Info

‘show io’ command - This command displays the number of read and write operations per volume as well as the number of 8KB page reads. These numbers are independent of whether the I/O is synchronous or asynchronous.
While a Recovery is active, you can also check upon it’s status in the KnlMsg <strong>file</strong> (versions 7.6+, otherwise in ‘knldiag’). In the above example, you can see how many pages have been recovered already, that the end of the Redo Log has been reached and a Savepoint is written. You can even see that the state of the DB is then changed from ADMIN to ONLINE, i.e. the Recovery was successful!
