logstat Example: Determine Databases that Are Active
To determine which databases are currently active, follow these steps:
1. Look at the List of active databases in the logstat output. For each database listed, the database's ID number, name, owner, and status appear on one line.
Note: The first entry listed is always owned by $ingres.
2. Note the ID number of each database. These numbers are used in the List of active transactions in the logstat output to identify the database associated with each transaction.
3. Compare the database ID numbers to the entries following the heading Database in the listings of active transactions. If you find a match, the database associated with that ID is currently active.
For example, in the sample output shown here, the second database shown is testdb owned by test. The ID for this database is 00280005. In the List of active transactions, the transaction listed belongs to Database: 00280005. The status of this database (testdb) is JOURNAL,FAST_COMMIT,ACTIVE. If an installation shutdown was pending, you can inform the testdb’s owner, test, of the impending shutdown.
