Lock dependecy status(show/hide) is now preserved

23 October 2004

Added option to visualize lock dependency between applications (A depends on B which depends on C), to access - right click in application window and "Show lock dependency".
Added option to display current/delayed configuration values (equivalent of the DB2 version 8 "show detail" option of the "get db/dbm cfg" command)
Minor fixes

06 October 2004

04 October 2004

04 May 2004
Fixed agentid value for lock monitor in v7.

03 May 2004
Added first version of "Debug" option for support. Cosmetic changes

02/04/04
Added "Agent Id" for the locks snapshot. Fixed tablespace monitor for v8 and DMS/SMS configuration.

09/03/04
Removed all changes related to context switching (multi-instance attachment, environment clean up) - too buggy (or I do not know how to use it correctly :(.

04/03/04
Hopefully the final fix to context switching (node number selection)

24/02/04
I've finally fixed the node selection on attachment.
Fixed XML output for tablespaces and bufferpools monitors.

17/02/04
Fixed tablespace, lock and table snapshots, which have been broken since 20/01/04

16/02/04
Partially fixed node number selection during attachment (EEE/ESE with DPF) - added "default" option (do not touch system settings). Not visible node selection is equivalent to default - I'm not using "set client" to specify node.
Currently I can not find an API method to reset node after attachment attempt. I know how to set it, but there is no method to reset(and I can't get a default value if %DB2NODE% is not set). You can either manually specify correct node number or open/close program (db2 terminate analog).

12/02/04
Added node number selection during attachemnt (EEE/ESE with DPF specific) - use small button with '^' on top of the window. Fixed minor bugs.

21/01/04
Fixed v7 and v6 dlls link and content.

20/01/04
Added "Db Browser" - information about tables, view, indexes, etc. Not finished.
Added "List history" - history information about backups, reorgs, etc.
Added ReorgCheck equivalent.
Internal code reorganization, various bug fixes.

Due to internal code reorganization and massive changes, the version can be unstable (I tested it fairly well, but...). By default, new version is shipped with v8 dll. If your client version is not v8, please download the corrpesonding zip file and replace the db2mon.dll. In theory db2monitor v7 dll should work with v8 client (not vise versa).

10/07/03
Multi-select save/force for applications. Custom attribute in application window.
Various bug fixes

08/01/03
Added delta values for snapshots (to turn on - edit->options )

07/17/03
Added computer/instance/db tree on attach screen (Alt-t or upper left '>')
Various bug fixes

05/22/03
Added dialog for schema name for SQLs without explicit schema prior explain (Edit->Options)
Fixed packaged SQL explain and some minor bugs

05/15/03
Added explain ability (via dynexpln and epxlain/db2exfmt combo).
Added saving monitor output to file (xml). Fixed some bugs

12/17/02
Added version 6.1 support ( download and replace db2mon.dll if your client version is 6.1)

10/26/02
Added tablespace/bufferpool changed values highlighting. Fixed minor bugs

10/15/02
Fixed db/dbm configuration window for v8 beta

10/04/02
Added tablespace data - allocation, containers information, ability to extend DMS. Connection to db is performed for tablespace data retrieval
Changed application window - more detailed application and statement information. Added support for new statements in cache between snapshots - highlights changed Execution/Preparation or full line if statement is new.
Added DB/DBM configuration information

10/04/02
Added Yahoo group for new version notification
http://groups.yahoo.com/group/db2monitor
If people will be interested, I will move it to non-"yahoo subscription required" place


09/12/02
Fixed bug with incorrect monitor switches setting. Download this version and check switches option, if you have version with 8-beta support (after 07/30).
Added drop down list of cataloged dbs in attached instance.

09/11/02
Added auto-refresh option - 10s, 30s, 1 and 5 min, default off. The setting value is not preserved across program restarts.

07/30/02
Added db2 8.1 beta support, just few new variable parsing, like memory pools. Because of lack of pre-8 support in the beta, separate dll is required. First attachment is performed using version 7 dll, the attached db version determined and v8 dll is loaded, if necessary.
Can be buggy.
Addition of container information on tablespace snapshot screen rerquires window redesign. I'm lazy, if people think they need it, email me, probably I will add it. In general if you have any ideas about program improvement, please share.

07/08/02
Added db lock snapshot processing

06/25/02
Added FCM parsing for dbm
Redesigned db & dbm section. Added changed values highlighting

06/22/02
Added db, dbm, bufferpool and table snapshots
Added db & node information on attach screen
Added global snapshots for EEE (edit->options)
