We have been successfully using SC3.4 for months to back up our Windows DB2 databases. Due to wanting to stay current and other reasons, we upgraded our SC to 3.6. I copied my old 3.4 config files for the servers to be backed up into the 3.6 installation path and upgraded my agents to 3.6. After doing that, I ran a test backup which fails very quickly. Here is a snippet of the log file:
[Thu Dec 6 13:37:36 2012] INFO: Logfile timestamp: 20121206133736
[Thu Dec 6 13:37:36 2012] INFO: Plugin validation skipped for db2, no plugin parameters file found or no parameters set
Unfortunately I am not able to restart my services at this time. I am not really thinking this is the issue though. I had it working perfectly under 3.4 using a local user do userid to connect to the db2 db. This part was was working fine. The only Change I made was upgrading sc. I am using the same config files on the snap Creator mgmt server. I am not aware of any config changes I needed to have made or preserved on the client side.
