jdbc connector error,after restart the connector,everything works fine

error log: can’t execute sql: “in sert into …”…
ora 02067 error: transaction or savepoint rollback required

when I execute sql in developer, i still met this error

And then, i restart the jdbc connector, everything went well.

And the wm service just inserts a table and calls a stored procedure in oracle.
This service has been running really well for several month.
The procedure has a automonoums transaction, i don’t know whether this mattered.

I’ve found the oracle error is about distributed transaction, but in my procedure ,there is no operation on remote database.

Any comments or guides?
Thanks a lot
