Hi experts,

Cannot switch database mode, error during dbm command:

db_online

End of knldiag

Background is that we don't have a final backup after upgrade from 7.9.8.0.22 to .28, so we restored into a .23 (old server has crashed, so we restored using SWPM).

The last log pages were created in .28. Do we have to clear the log area?

    Hello Daniel,

    this sounds strange - can you create an SAP ticket, open the OS connection to the database server and let me know the ticket#?
    To get around this, yes, you will likely need to clear the log. However, at the moment I do not fully understand what has happened at your system - can you explain the sequence of events in more detail?
