Local fix
Problem summary
**************************************************************** * USERS AFFECTED: WebSphere eXtreme Scale users * * with environments that handle container * * failover scenarios. * **************************************************************** * PROBLEM DESCRIPTION: After a failover, many transaction * * timeout or lock timeout exceptions * * occur. * **************************************************************** * RECOMMENDATION: * **************************************************************** When partitions are replaced after a WebSphere eXtreme Scale container fails, partition placement fails to gracefully quiesce running transactions, leaving the transactions to timeout and rollback. During this time, the application can experience lock timeout exception errors. After the transactions timeout, the result will be CWOBJ0061W messages and transaction timeout exceptions. Normal processing resumes after the timeout occurs.
Problem conclusion
The partition placement is deferred until the transactions complete or an appropriate wait time occurs.
Temporary fix
