Issue:
While running a database archive, the archive or trim will fail with a 'timeout expired' error as shown below:
Running the archive or trim again over a much shorter time interval, such as an hour, will succeed.
Product Line:
Power Monitoring Expert 7.2.2
Environment:
Database Manager
Database Trim and Archive
Cause:
There were a number of timeout settings with Database Manager that were causing these issues. The timeouts were mainly a 30 second Trim timeout and an 18 hour archive timeout.
Resolution:
There is a hotfix available that will remove these timeout settings. In addition, the attached hotfix will also speed up the trim and archive process, without the unwanted side effects of a huge transaction log size increase and database tables locking up.
*Warning: Take backups of any files prior to modifying them. Ensure the backups are in a location that will not be overwritten (i.e. the Desktop).
