Discover Readme File ==================== This is the README file for Discover release 3.32. *IMPORTANT NOTE* To upgrade from a version of Discover prior to release 3.30, you will need a new license. Release 3.30 licenses and later are still valid with release 3.32. Contents ======== System Requirements Recommended Settings Installation Instructions Installing the Discover monitor on additional NSK systems Upgrading Discover from a previous release Changes introduced in release 3.32 Changes introduced in release 3.31 Changes introduced in release 3.30 Changes introduced in release 3.26 Changes introduced in release 3.25 Changes introduced in release 3.24 Changes introduced in release 3.23 Changes introduced in release 3.22 Changes introduced in release 3.21 Changes introduced in release 3.20 Changes introduced in release 3.12 Changes introduced in release 3.11 Changes introduced in release 3.10 Changes introduced in release 3.02 Changes introduced in release 3.01 Changes introduced in release 3.00 *************************************************************************** System Requirements =================== PC Windows Vista, XP or Windows 2000 Professional (SP2 or later). NonStop System Itanium H series, Himalaya S series (G03 or later), or K series (D40 or later). *************************************************************************** Recommended Settings ==================== 1. The Discover GUI has been tested at resolutions: 800x600, 1024x768 and 1280x1024, with both small and large fonts. A resolution of at least 1024x768 with large fonts is recommended. *************************************************************************** Installation Instructions ========================= How to install Discover: If you are installing the PC based client, follow the instructions in the setup and configuration wizards. These will be started the first time that you run the Discover client. They will install Discover on your PC and optionally on the NSK system. To install the Discover Server only (or to install the server manually): 1 You will need a DCVRSnnn.ZIP file, which contains: README.TXT (this file) DCVRPACK.100 (Discover installation program) Use PKUNZIP to un-zip these files. You also need a copy of the following files: LICENSE.101 (Discover License file) DCVRREF.DOC (Discover Reference Guide) DCVRUSER.DOC (Discover Users Guide) You can get a copy of these by contacting Merlon at (416) 504-8727, or toll free in North America at 1-888-463-7566. 2. Copy the LICENSE and DCVRPACK files to the Tandem system. Use IXF, FTP, or a similar file transfer program. The files should be placed in the same subvolume on the Tandem system. Important Note: The file DCVRPACK is a binary file, the LICENSE file is an ASCII file. Make sure you select the correct file transfer mode for each file. 3. Logon to the Tandem system using TACL, and set your current subvolume to where you copied the Discover files. 4. Use FUP to alter the code of the DCVRPACK file to 100, for example FUP ALTER DCVRPACK, CODE 100 5. RUN the DCVRPACK file, for example: RUN DCVRPACK 6. The DCVRPACK program prompts for continuation, answer Y. 7. DCVRPACK creates a set of files in your current subvolume. These are the code and data files needed by Discover. When DCVRPACK has finished, it starts the SETUP program. 8. The SETUP program completes the installation of Discover. You will be asked to supply some information by SETUP. Discover is now installed. The RD macro is used to start the Discover monitor process. You should review this macro to ensure that the choice of CPU and OUT file meets your requirements. Run the RD macro to start the Discover monitor. Run the DCI program to issue commands to the Discover monitor. Many aspects of Discover's operation are controlled by the settings in the DCVINI file. You might want to print a copy of the file and consult "The Discover DCVINI File" section of the Reference Guide to check the values are appropriate for your system. *************************************************************************** Installing the Discover monitor on additional NSK systems ========================================================= If you are using the PC-based client, and have already done a full Discover installation on your workstation and on at least one system, you can install the NSK components of Discover on additional systems by: 1. Start the client 2. Ensure that you are not connected. If the client has automatically connected to a system, click on Disconnect in the Session menu. 3. Select NSK Setup from the Tools menu, and follow the instructions in the wizard. *************************************************************************** Upgrading Discover from a previous release =========================================== If you are upgrading from an older release of Discover, we recommend that you upgrade the software "in place", that is in the same Discover subvolume. To do this, proceed as follows: 1. Stop the Discover monitor process, and any DSC processes that are running from the same subvolume 2. Make a backup copy of all the files in the Disover subvolume. (either to tape, or to another disk subvolume}. 3. If you are using the Discover PC based client, run the installation package and follow the setup instructions. To complete the upgrade of the Discover server manually: 4. Replace the DCVRPACK and LICENSE files with the new version. 5. FUP ALTER DCVRPACK, CODE 100 6. Run DCVRPACK, and follow the normal installation steps. If you are upgrading from a 2.xx to a 3.xx release, SETUP will ask you whether you wish to change the DCVINI settings, if you answer NO (recommended), you will not be prompted for new DCVINI settings. You WILL be prompted for a few monitor- related settings that are not stored in the DCVINI file. IMPORTANT: See item 1 in the Release 2.30 changes section for special instructions on installing 2.30. Note that if you choose to change settings, SETUP attempts to ADD some sample worksheets, you may see error messages indicating that the ADD WS commands failed, since the worksheets already exist. You can ignore these error messages. If you are upgrading from a 1.xx release to a 3.xx release, SETUP asks you whether you wish to continue. If you answer YES (recommended), you will be prompted for DCVINI settings, and the old settings will be overwritten. 7. After SETUP has finished, Discover has been upgraded. Review the RD macro before using it to start the Discover monitor. If you change your mind about changing DCVINI settings after SETUP has finished, you can use the DCVINI file from the previous version. To do so, stop the monitor process, copy the DCVINI file from the backup copy you made in step 2, and re-start the monitor. *************************************************************************** Changes introduced in release 3.32 ================================== IMPORTANT NOTE: As of this release, Discover has replaced optional dynamic or static TCP/IP connections with a private listener process that provides additional Discover-specific features (see #2, below). If you are using static connections, Discover installation will automatically update your configuration to use the private listener with the lowest port in the port range. All client connection requests will be addressed on this port. If you are using dynamic configuration, please remove the DSC reference from your PORTCONF file to avoid conflicts with the system LISTNER. 1. Windows Vista help support for compiled help has been accommodated. 2. The method of client communication has changed (DI81000843). There is no longer an optional static or dynamic connection, but rather a Discover-specific private listener that runs from the Discover installation subvolume. Several corrections and improvements have also been made to the Discover client. *************************************************************************** Changes introduced in release 3.31 ================================== 1. A single Discover client can simultaneously access multiple Discover Monitors (DI81000584). 2. Discover now monitors and repairs SQL/MX objects (DI81000587). 3. A summary report is now generated at the completion of the Discover SCAN (DI81000635). 4. The ACCESSCONTROL section has been added to the DCVINI file to allow encryption rules for client connections to be enforced at the server (SM45000632). 5. A new condition, TOOMUCHFLABUSED has been added as well as the file attribute, FLABUSED, to monitor consumption of a file's label (DI81000745). 6. Two new conditions, MAXSIZEINCREASED and MAXSIZEDECREASED have been added to monitor changes to the maximum size of a file (DI81000801). Several corrections and improvements have also been made to the Discover client. *************************************************************************** Changes introduced in release 3.30 ================================== 1. The Discover Monitor has been certified for use on the Itanium platform (H-Series). 2. Support for extent analysis has been added for disks larger than 72 Gb (DI81000569) 3. Long term file full projections now use the largest projection interval, rather than the peak growth rate (DI81000571). 4. NEGATIVEREMOVAL processing has been improved (DI81000572). *************************************************************************** Changes introduced in release 3.26 ================================== 1. A flaw in FREEBLOCKS calculation that could cause the Discover Monitor to abend on large files (more than 400,000 free blocks) has been corrected. Please note that this is a server-only change, so the Discover client version will remain at 3.25. *************************************************************************** Changes introduced in release 3.25 ================================== IMPORTANT NOTE FOR WINDOWS XP AND 2000 USERS: As of this release, Discover stores its client configuration (*.INI files) and session connection information (*.SSP files) in \Documents and Settings\\MERLON\Discover, rather than in the Discover installation directory (default \Program Files\Merlon\Discover) For existing clients, please move Discover.INI, DGUI.INI and all files of type .SSP to the appropriate directory to maintain client configuration and to ensure existing sessions are still available. 1. Worksheet dispositions will be processed without starting a separate process (such as FUP for GIVE dispositions) for each file in the worksheet. (DI81000392). 2. The VDIAG tool has been enhanced to optionally display growth from an entered date, rather than just since the last scan. (DI81000435). 3. SMF files may be locally-qualified (i.e. without a system name) in user-defined conditions, filters and file group definitions (DI81000394). 4. The FILECORRUPT condition will no longer be triggered on open files (i.e. those that are currently being loaded or duplicated) (DI81000415). 5. History charts have been corrected to include the latest scan information (DI81000423). 6. User defined conditions will now "inherit" inserts, so that, for instance, if you use ORPHANFILE in a condition, the %OWNER and %MANAGER inserts will be available. Note this also includes inserts appropriate to the criteria used in a user-defined condition, so that %LASTOPENTIME will also be added to correspond to the LASTOPENTIME criteria. (DI81000434). 7. The AUDITCOMPRESS file attribute is now monitored by Discover (DI81000433). 8. The UTILINI file was being intermittently cleared - this has been corrected (DI81000429). 9. The SCANNEDFILES list, which defines files to be included and excluded from the scan, may be controlled from the client (DI81000350). 10. The client no longer displays "stale" data when objects are selected (DI81000409). 11. ORPHANFILE will not be triggered for EXCLUDED files (DI81000340). 12. Estimated file full times are provided for files that do not match the FILEFULLn criteria (DI81000438). 13. The DCVADMIN file was being overridden during a new installation, which could allow unauthorized access to the Discover configuration. This has been corrected (DI81000341). 14. The TODO list displayed on the client may now be filtered by category as well as task state (DI81000254). 15. The DCI TODO list display no longer loops when more than twenty tasks have identical timestamps (DI81000436). 16. Stored charts can be managed from the Charts item in the main menu of the Discover client (DI81000102). 17. The File Full Summary report now includes a percent full column indicating each file's current size compared to its maximum (DI81000024). 18. Multiple tasks may be selected in the TODO list for manipulation and execution (DI81000131). 19. Halt task has been added to the task object menu in the TODO list (DI81000444). 20. Points may now be suppressed from Discover's history to remove single- instance growth spikes, such as file loads (DI81000489). 21. A new condition, SCANFINISHED, has been added that is triggered at scan completion (DI81000490). 22. The maximum number of disks scanned by a single Discover monitor has been increased to 512 (DI81000493). 23. DONTPROJECTBEFORE now applies to disk volumes as well as files (DI81000494). 24. The simulation for extent growth on file groups has been improved (DI81000496). 25. EXTENT, FREEPAGES, and PAGES inserts have been added to the DISKFULL condition (DI81000498). 26. A RATE insert has been added to the VOLUMEDIAGNOSE condition (DI81000501). 27. NEGATIVEREMOVAL detection of growth "spikes" has been improved (DI81000503). *************************************************************************** Changes introduced in release 3.24 ================================== 1. The percentage of unused blocks present in a file is included as (TOOMANY)FREEBLOCKS for triggering either conditions or as worksheet filters. 2. Dependencies have been added to action scheduling specifications. Subseqent actions may be performed only if the previous action for the condition failed or succeeded. This corresponds to the DCI IFFAIL and IFOK tokens. 3. The FC command now functions properly in the DCI tab of the client. 4. Several changes have been made to the charting facility: - Zooming and panning are now disabled on the charts that appear under the History and Forecheck tabs to prevent confusion. - Double click of the chart under the forecheck no longer opens the history chart form. - The date range on history charts is now set so the latest date is always displayed to more clearly indicate the chart's range. - When double-clicking the History tab chart, the chart window is sized so that the dates that appear on the axis are the same as those from the History tab chart. - For history charts containing multiple series displayed in percentage format, the percent used now reflects each series individually (e.g. a 20Mb file with a maximum size of 100Mb is shown as 20%, as is a 1Mb file with a maximum size of 5Mb). - Changing a bar chart with multiple series to use stacked bars is now allowed. - Printing of charts has been improved in terms of readability and consistency between previews and hard copy. A print setup function has also been added to the chart window. - Files for which Discover history does not exist may not be added to charts. - Group history charts are now displayed correctly when there are less than three data points - if no history exists for a given group, the history chart is not displayed under the history tab. 5. A Guardian error 66 reported deletion of more than 99 tasks using the DCI has been corrected. 6. DCI obey files may now include comments - any lines prefaced with "--" will be ignored by DCI. 7. The Discover server may now be started and stopped from the client Tools menu. 8. The BACKUP disposition now functions correctly for files updated prior to January 1, 2000. 9. The EXTEND disposition may now be configured to add extents to a file to accommodate a number of days expected growth. Please note that this feature may only be used if Discover is monitoring the file in question. 10. The limit of approximately 1600 subvolumes per disk and files per subvolume has been removed. 11. In the Groups tree, only disk volumes that contain files in a particular group will be displayed under that group. 12. The maximum size of a group has been changed from the aggregate disk capacity of the disk volumes containing files in that group to the aggregate maximum size of the files within the group (limited by disk capacity). 13. Installation of Discover from the Discover client includes the option to maintain an existing license file, rather than requiring that licensing information be re-entered. 14. Changes to the SCANNEDFILES list are now stored on the Discover INI file to prevent loss of information during an uncontrolled shutdown. 15. The File Full report wizard includes an option to display all files, including those that are already full, or only to display files that Discover predicts will be full at a future date. 16. Handling of the Detect Changes attribute of disk volumes has been corrected. 17. A function has been added to the Worksheet Object menu to delete multiple files from the worksheet based upon a file name pattern. 18. A new column, "Execution Message", has been added to the worksheet summary to provide additional information on files for which the disposition has failed. 19. When a worksheet is executed from the GUI, it is placed on the TODO list according to the current NSK time (i.e. immediate execution), rather than the PC local time. 20. The worksheet enable flag has been added to the worksheet summary. 21. When a worksheet with no active dispositions is executed, the worksheet stopped message is logged to EMS to indicate that it has completed. 22. A new value, History Chart Interval, has been added to the View menu to control the period over which the history charts appear in the History Tab. The default for this is 30 days. *************************************************************************** Changes introduced in release 3.23 ================================== 1. Previously, using the refresh button on the task bar to refresh the TODO list did not work correctly. This has been corrected, as well as allowing the refresh of a single task by selecting that task and pressing the refresh button. 2. Previously, selecting a specific TODO list entry sometimes caused the details text to be truncated or replaced by a very abbreviated form. 3. TODO list navigation by paging as well as date and time has been improved. 4. TODO execution of tasks now indicates that the task has been rescheduled (to be executed immediately) by dimming the task entry. 5. The time taken to do a refresh of the users summary has been significantly improved. 6. Previously, the new user quota wizard did not properly parse the userid - in fact it dropped the last digit. This has been corrected. 7. Chart functions have been improved as follows: - If a chart was open during session termination, it was possible to cause a number of errors, including the message "Data Manager Release Failed". This has been resolved. - When a chart is displayed before Discover has gathered any data (i.e. the first scan), the GUI could lock up - this has been corrected. - Multi-page charts allow for large collections of data, as well as scrolling of zoomed charts. - Zooming of charts has been corrected to correctly return to previous sizes when zooming in and out. - Default chart properties are now appropriate to the type of chart selected. - Selected chart properties are maintained between GUI sessions. - The FREE.SPACE and NONGROUP.FILES groups are no longer lost after initial display of the Allocation by File Group by Volume chart. - Filtering by disk volume has been corrected in the Group History Chart. 8. A number of problems with reports that were related to restoring column sizes, fonts, or sorting were corrected. These problems tended to manifest themselves as "List Index out of bounds" errors. Several report fields mistakenly reported as pages/bytes have also been corrected. 9. In some reports where no data was selected, a GPF could occur. This has been fixed. 10. Direct editing of SQL object attributes, such as file codes, is no longer allowed. 11. The refresh function is now performed when the object being refreshed is a collapsed tree node. 12. Toggling the view of all files versus viewing files by history now updates the files folder correctly. 13. The volumes summary tab values have been corrected to properly reflect disc capacity and allocations in percentages, if so selected. 14. When editing files using the Tools...Editor option, a picklist of recently edited files has been added as well as warnings when saving to existing files. 15. Filtering by user has been added to the User Quota report. 16. The worksheet properties tab now include drop-down boxes for filters and dispositions, as well as the ability to add a new filter or disposition when altering the worksheet. 17. The condition MODIFIEDTIMECHANGE was added. This condition is triggered when Discover detects that the file has been modified since the last scan. *************************************************************************** Changes introduced in release 3.22 ================================== 1. Icons were added to each node in the browse trees. 2. It was possible to cause the GUI to display a non-existant and erroneous todo entry when moving backwards through the Todo List. A message box indicating an "Internal Error ... Invalid argument to date encode" would ensue. This problem has been fixed. 3. When deleting Todo Entries, it was possible to cause the GUI to attempt the deletion of a single Todo Entry twice. This caused a message box to pop up with an "Invalid Marker" error. This has been fixed. 4. For versions 3.20, and 3.21 the version of the DMAIL program included was 3.13. This caused MAIL actions to fail with a license error. This has been corrected. 5. The DMAIL program previously set the MAIL FROM line to the name of the host. This is now set to the FROM parameter from the UTILINI file. 6. Previously, altering a critical file definition caused the changes to be made to the in memory copy of the information only. The change would appear to have been made until the monitor was shutdown and restarted, when the altered definition would disappear. This has been corrected. 7. Under some circumstances, it was possible that the Discover monitor was not aware that a subprocess had stopped. If the subprocess was a DSAP or PUP process started during a scan, this could cause scanning to be suspended until the monitor was restarted. Discover now checks each process that it starts on a regular basis, detects and recovers from this type of situation. 8. When using the modify quota wizard, Discover refused to accept the target userid because it contained the logon name in parentheses. This has been corrected. 9. Occasionally, displaying the details of a todo note entry with the GUI caused garbage to be diosplayed in the parameters section. 10. The refresh operation now works correctly for a todo entry. 11. A number of problems with the critical file summary were corrected. 12. If a disk volume was not configured, any attempt to display or manipulate it with the GUI caused a GPF. This has been corrected. 13. When the GUI was started and attempted to connect to a monitor that was not running, a GPF could occur. This has been corrected. 14. Various wizards were not causing a refresh after they had been run. This meant that after running a wizard to create a new object, the display would have to be manually refreshed to see the just created item. The wizards have been modified to automatically refresh the display. 15. The Editor open PC file dialog box was changed to support filtering for text files. 16. Filters and conditions which included an initial pattern containing + wildcard characters were rejected by the GUI. This has been fixed. 17. When an action wsa configured to run a program, it was possible to construct a command line containing return characters. These caused difficulty for most programs. Return characters are now ignored in the argument text. 18. Previously, Discover would skip over a critical file pattern that followed immediately after another file pattern that matched no files. This has been fixed. 19. When calculating predicted values for a report, a numeric overflow could occur if the beginning date for the report was significantly earlier than the first data point in the record. 20. Previously, the growth rate and the maximum size of a file were displayed incorrectly in the history tab. *************************************************************************** Changes introduced in release 3.21 ================================== 1. Improvements to error reporting for properties, history, and task tabs. 2. When a worksheet name contained an underscore, any operations to the files on the worksheet in the GUI would fail. This has been corrected. 3. The file summary report was incorrectly titled "Deleted Files" - This has been corrected. 4. The Delete toolbar button did not work correctly for Todo List entries. (In fact it cleared the entire display, but had no permanent effect). It now deletes the currently selected Todo entry. 5. Deleting a Todo list entry with the right click menu did not update the display of the entry's state. It is now correctly marked deleted. 6. Previously, the GUI would display only the first 25 files on a worksheet. This has been corrected. 7. Not all conditions and actions were reported by the SHOW COND * and SHOW ACTION * commands in DCI. Neither were they all displayed in the GUI. This has been corrected. 8. Previously, in lists where only a single item could be selected at once (e.g. the task list), the right click operation operated on the item underneath the current mouse position, rather than the currently selected item. This has been changed so that if a right click occurs on an item that is not currently selected, it becomes the currently selected item. You must right click on the currently selected item to cause the right click menu item to appear. In lists that allow changes to many items at once, the right click menu operates only on the selected items (this is unchanged from the previous release). 9. In release 3.20, the GUI displayed an incorrect value for the growth rate of a volume. This has been corrected. *************************************************************************** Changes introduced in release 3.20 ================================== 1. Considerable changes were made to the infrastructure of the GUI for this release. This has improved both the speed and robustness of the GUI. 2. There are now summary tabs for Conditions, Dispositions, and Filters. 3. You can now copy the contents of most report views to the clipboard. For example, you can copy selected records from the worksheet file tab to the clipboard using the Edit menu (or ctrl-c). 4. Previously, if a user-defined condition contained an underscore character, the corresponding condition was not found, and the "no action defined" error was reported. This has beed corrected. 5. When a file had a very small EOF and a large number of allocated pages, it was possible for Discover to fail with a numeric overflow. This has been corrected. 6. Problems opening the DCVFH file were not always reported. If there was a problem with the alternate key file, Discover would be unable to expand the files tree or locate file history. In this release, an error message is logged to the Discover out file. 7. The commands: SUSPEND TODO and RESUME TODO were added to DCI. These commands temporarily suspend Discover activity (such as reloads). See the DCI HELP for more information. *************************************************************************** Changes introduced in release 3.12 ================================== 1. Previously, TODO records were always written to the DCVTODO file with their maximum size. This was wasteful of space since much of the data at the end of the record was for optional parameters. TODO records are now truncated when appropriate. 2. Previously, a worksheet could be secured so that the owner of the worksheet was denied access. Discover no longer denies access to the owner of a worksheet, whatever the security setting. 3. A worksheet created using the New Worksheet Wizard now has a default security of "AAAA". The security was previously undefined. 4. In DCI, setting the page size to zero (to turn paging off), would eventually cause an overflow trap because an internal line counter overflowed. This has been corrected. 5. Previously, an empty criteria (in a condition or group specification), would match any file. It now matches no files. 6. The condition CRITICALFILEERROR was added. This condition is detected when a file in the critical file list cannot be monitored because of a Guardian error. This condition could for example be used to start a TACL macro that attempts to create the file if the error code is 11. Note that in previous releases, Discover would unconditionally report this error to its outfile. Since the condition can now produce a message (if desired), Discover no longer unconditionally writes a message to the outfile. 7. The condition CREATIONTIMECHANGE was added. This condition is triggered when Discover detects that the creation timestamp for a file is different from the one recored in the last scan. This usually indicates that the file has been replaced. 8. Individual actions for a condition can now be configured to be dependent on the preceding action. This is done by adding an IFOK or IFFAIL prefix to the action. There are some restrictions on the use of this feature. Type HELP ACTIONS in DCI for more information on use. 9. The small file threshold for a volume can now be set to zero (with the command ALTER VOLUME $vol THRESH 0 KB. This effectively disables the small files group for the volume. 10. Previously, setting the action associated with a condition to a syntactically incorrect value caused the previous in memory action defintion to be lost. If a correct action definition was not subsequently entered, the condition could be ingored until the next time that Discover was restarted. This has been corrected. 11. It is now possible to delete a group definition. This can be done with the GUI or with the DCI command: SET GROUP groupname= 12. It is now possible to delete a condition definition. This can be done with the GUI or with the DCI command: SET CONDITION condname= 13. This version of Discover contains a workaround for evaluating the index levels on Format 2 SQL Tables: this information is not reported properly by Guardian. Discover now determines the number of index levels when it performs slack or disorder analysis. 14. When the scan interval is set to one day (1440 minutes), Discover automatically adjusts for daylight savings time transitions by always scheduling the scan for the same time of day. 15. The output from SHOW ACTION * and SHOW CONDITION * is now sorted. 16. QUICKSCAN mode was added. Type HELP QUICKSCAN in DCI for more information on this feature. In this mode, Discover will not examine all of the files on configured volumes. Instead, for each configured volume, it will examine only those files that are included in the SCANNEDFILES list. These files can be manipulated with the DCI commands: ADD INCLUDE ADD EXCLUDE DELETE INCLUDE DELETE EXCLUDE LIST SCANNEDFILES 17. Previously, an action added via the GUI or DCI clients had an incorrect message number generated when sent to an EMS collector. This situation corrected itself if Discover was shutdown and then restarted. This bug has now been corrected. *************************************************************************** Changes introduced in release 3.11 ================================== 1. Version 3.11 contains a fix for a bug which caused reload worksheets to be incorrectly rescheduled when a reload was suspended and it was not the first reload executed by the worksheet. Version 3.11 is a server release only. *************************************************************************** Changes introduced in release 3.10 ================================== 1. Version 3.10 includes the Discover Worksheet Editor (DWE). This component can be installed on client PCs and used to manipulate worksheets belonging to the user. DWE is intended to provide access to Discover worksheets by end-users or other non-administrative staff. 2. It is now possible to specify a CPU parameter for RELOAD. The following bug fixes are included in release 3.10: 1. (--) A bug handling file-open warnings in the recycle bin was corrected. 2. (--) Setup now allows for the possibility of a port other than 23 for telnet services. 3. (--) Timestamps on worksheet file entries are corrected to local time, rather than GMT. 4. (--) The DCI RUN command waited versus nowaited handling has been corrected. 5. (93) A configured volume which was unavailable could pick up history values from the previous volume scanned. This has been corrected. 6. (95) Modifying a worksheet using the worksheet wizard would unconditionally set the autosignoff and redo flags. As well, the worksheet security was not preserved. This has been corrected. 7. (--) Several bugs were corrected relating to the constructoin of "matrix" reports. An option was added to control the orientation of these reports (where feasible). 8. (--) Selecting landscape mode from the print setup menu now works properly. 9. (--) Previously, files which were contained on SMF volumes were recorded in the history database with the system name present. This had the unfortunate side effect that they were undisplayable with DCI or the GUI. This has been corrected. Known Problems: 1. When displaying a large amount of data in matrix reports, resource depletions can occur. This is sometimes characterized by a message which reads "Invalid Parameter". Suggested workarounds are: 1. Try unchecking the "show individual items horizontally" checkbox in the report wizard. 2. Select less data (usually files) for display. 3. Decrease the number of colors displayed in the Windows Display properties window. *************************************************************************** Changes introduced in release 3.02 ================================== The following bug fixes are included in release 3.02: 1. (63) For charts properties, the remove function did not properly remove an item from the chart. This has been corrected. 2. (88) The DSC program did not correctly locate the discover monitor unless either the backup or primary process was in CPU 0. This has been corrected. 3. (--) The Print Item in the File menu of the Chart window now functions correctly. Previously, it was necessary to use the tool bar button. 4. (--) A "Copy Chart" function was added to the Chart window. This feature copies the current chart to the clipboard. 5. (--) Fetching of matching file data for the File History Report has been improved. 6. (--) Changed the default FILEFULL and DISKFULL warning messages to correctly reflect the default intervals. *************************************************************************** Changes introduced in release 3.01 ================================== The following bug fixes are included in release 3.01: 1. (76) Setting the number of volumes to 20 on the capacity chart no longer causes a GPF. 2. (77) Processes started by the DCI RUN command were unconditionally started nowaited. This is now true only when the NOWAIT option is specified. 3. (78) Previously, Discover would abort the scan when it encountered a volume for which there was no disk process if scan was enabled for that volume. This has been corrected. 4. (79) The tree pane was disabled after history was requested for an object which had none. This has been corrected. 5. (81) Refresh did not work properly for volumes when the forecheck tab was selected. No data was fetched until the volumes node was expanded. This has been corrected. 6. (72) Automatic refresh of the volume forecheck summary is now working properly. 7. (80) The growth rate values for volumes are now displayed in MB/min or KB/min. 8. (--) A number of small memory leaks were corrected. 9. (47) User logon names are now displayed in addition to the userids in the user tree and user summary reports. 10. (51) Previously, the audited property of a file could not be set -- an error 590 was reported. This has been corrected. 11. (75) The monitor property "Configured Volumes" was changed to "Volumes Configured". As well a new property "Volumes to be scanned" shows the number of volumes that are enabled for scan. 12. (82) The tree pane was disabled after the an attempt to expand the children of the "Monitor" node. This can no longer be done. 13. (85) Expanding the "Users" node looped forever if there were more than 128 users with quota information. 14. (87) Previously, when altering the properties of another object, the property would not be updated unless the user selected another property or pressed the enter key. If another object was selected, the outstanding change would be lost. This has been fixed. 15. (--) A bug which could cause nodes to become lost was corrected. This manifested itself as an exception during the clean up processing, when the program was terminating. *************************************************************************** Changes introduced in release 3.00 ================================== 3.00 is the first release of Discover to support the Graphical User Interface. You can install the GUI (also known as the Discover Client) on a system running Windows 98, Windows NT Workstation (with Service Pack 4 or greater installed), or Windows 2000. If you install the client on Windows NT, you may have difficulty with some displays unless you obtain and run a copy of 50comupd.exe from microsoft.com. Other changes are: 1. A bug which caused history points to be occasionally dropped from the disk or volume history records was corrected. 2. The maximum number of critical files definitions has been changed to 4096. As well, critical file definitions can now include wildcards. 3. A bug which prevented listing the files in a worksheet unless the user had write access to the worksheet was corrected. 4. Previously, if a file could not be added to a worksheet due to some problem with the DCVWSF file, Discover did not produce a message. It will now produce a message for the first occurance of this situation during a scan. As well, this will be noted in the worksheet info. 5. Discover now logs all worksheet start and stop events to the outfile. 6. Two new conditions have been added: INCOMPLETEDDL is detected for SQL objects for which an ALTER has failed during a merge or move operation when the SHARED ACCESS option was set. (A new action - RECOVERDDL - has been added to perform an appropriate recovery for this condition). UNRECLAIMED is detected for SQL objects for which there is unreclaimed free space. *************************************************************************** Copyright ========= Portions of this software are Copyright (c) 1993 - 2003, Chad Z.
