Description Marek Baluch 2011-10-20 14:28:12 UTC

Affects: Release Notes
project_key: SOA

The 'AcquireInstanceLock' exception may start popping up in the server log under heavy load.

Note from Jeff Yu: "So when you are doing the load tests again, you would see some 'AcquireInstanceLock' exceptions, thats fine because those jobs that didn't get the 'Instance Lock' successfully will be inserted into ODE_JOB table and got retried until they are succeed."

Link: Added: This issue depends RIFTSAW-456

Comment 2 Marek Baluch 2011-10-20 14:32:14 UTC

This will be fixed in Riftsaw 3 which I think will not make it into SOA 5.2. IMO we should document this as known issue.

If your server is working at high capacity, you may encounter 'AcquireInstanceLock' exceptions.  These have no impact as those jobs which did not obtain the 'Instance Lock' are sent to the ODE_JOB table from where they will be retried until they process successfully.

Added to the release notes.
