Table Locking Issue
I am trying to work out how a custom concurrent program fails intermittently when calling oracle core API JTF_TASKS_PUB.UPDATE_TASK within the custom code.
I have pin-pointed the exact piece of code that is failing in the API.
It is failing when trying to perform an update on table IEU_UWQM_ITEMS.
I think the reason the update is failing is because this table was somehow locked at the time of the update.
The other reason I think it is a locking issue is because I cannot replicate this issue on a test environment and it happens intermittently on the live system.
