Symptoms
An APS-related task fails with an error like below:
Task name Provisioning "context" for APS application BlackBerry 10
Last execution output Internal error: SDK::Platform::blob Plesk::SaaS::SaaSManagerTasks_impl::taskExecuteWorkflow(const SDK::Platform::Properties&) : [APSC] system exception, ID 'IDL:omg.org/CORBA/TRANSACTION_ROLLEDBACK:1.0' Unknown vendor minor code id (0), minor code = 0, completed = NO
Cause
The issue is probably caused by APS-15464, which was fixed in OA 5.5.5.
The cause is that during task execution DB connection times out while APSC transaction is still running, the connection is killed and the corresponding transaction is rolled back.
Resolution
Please uodate to version higher than or 5.5.5.
To workaround update the following parameter in /usr/local/pem/etc/Kernel.conf file on POA Management node to higher values:
db_service.connection_timeout
db_service.transactional_connection_timeout
Recommended values for both are 1200, but it could vary depending on the task.
After the change, restart pem service on POA Management Node and re-run the task.
