In DB2, how to know date/time a particular Database was put to RO?

[saurabhgaur]

Is there any place where one can find at what date/time a particular Database was put to RO? Or got any change in status ? Is that available to see somewhere in the subsystem catalog or BSDS?

As far as I know, there isn't a single, definitive way to pinpoint the exact moment a DB2 database was switched to read-only (RO) status. However, there are several methods that can help you narrow down the timeframe:1. DB2 Logs:

• Check the DB2 diagnostic log files (db2diag.log and others) for relevant entries. These logs may contain timestamps and messages indicating the database being placed in RO mode. Look for keywords like "READONLY" or "STOP DATABASE".
• The timeframe covered by the logs will depend on your log rotation settings.

2. System Operations Staff:

• If the RO switch was due to a planned maintenance activity, system administrators or operations staff likely have records of the specific time window.

3. Monitoring Tools:

• If your organization uses database monitoring tools, they might have logged events related to the database status change. These tools can provide a more precise timestamp for the RO transition.

4. DB2 Commands: While not necessarily revealing the exact time, you can use the

Code: Select all

DISPLAY DATABASE

command to check the current status of the database, including whether it's read-only or read-write. This might help confirm if it's currently in RO mode. By combining information from these sources, you can get a clearer picture of when the database was switched to RO status.
