I am auditing one of our servers...and some of the findings straight from DB CFG:
DB2 UDB v8.2, Fixpak 7, Windows XP
First Log archive method(LOGARCHMETH1) : OFF
Second Log archive method(LOGARCHMETH2) : OFF
LOGRETAIN : off
USEREXIT : OFF
HADR database role : STANDARD
HADR timeout value(HADR_TIMEOUT) : 120
HADR log write synchronization mode : NEARSYNC
Automatic database backup(AUTO_DB_BACKUP): ON
I checked up the db2diag.log and history to check for the last backup image which is like way back in Jan'06 which is loacted on the same drive.(not using TSM, don't know if they are backing up on some other drive) No schedules exists in DB2 (Tools catalog has not been configured) or Windows Scheduler considering the fact that Auto_db_backup is set to ON.Though Health Monitor is generating alerts that backup and RUNSTATS required.
Now my question is:
1. Is there a way to find out if backups are taken on some other drive, or if using any external software like Veritas.
2. Since HADR feature is enabled, does that makes sure that database can be recovered from the standby database server considering the fact that LOGRETAIN AND USEREXIT are both turned OFF.
3. I know this for sure that for the logs to be copied automatically to the standby USEREXIT should be enabled,right?
4. How do I get to know that the hot and standby are synchronized.
I know these are lot of questions but all of them are interconnected...let me know if you need any clarification on any of the questions.
Hope I get some help to clear my confusion.

HADR is not activated when HADR database role is STANDARD.
If you run a snaphot on the database, you will see HADR status (should be in Peer state if HADR is working properly) and you can see log positions on both the primary and standby database (sometimes there is a temporary difference in the log positions, so don't be alarmed). If you don't see any HADR information in the snapshot, then HADR is not configured.
db2 get snapshot for db on db-name
BTW, I would strongly recommend that you upgrade to FP 11. There have been over 1200 APAR's fixed since the FP 7 (the first release of DB2 8.2).
