TRANSACTION_ROLLED_BACK_CWOBJ0061W=CWOBJ0061W: The transaction with TxID, {0}, that was last running on thread, {1}, on shard {2} has exceeded the configured transaction timeout value and was been marked rollback-only. This might be caused by lock contention or application deadlock, or your transaction timeout value is set too small.
Explanation
WebSphere eXtreme Scale automatically marks a transaction rollback-only, when it has exceeded its configured transaction timeout value. This might be caused by lock contention or application deadlock, or your transaction timeout value is set too small.
User response
Examine the application logic to determine whether a lock contention can be avoided. If a deadlock situation exists, remove that logic. If the transaction timeout value is too small and your application expects a long transaction, increase the transaction timeout value appropriately.
