PQ60432: NO EXCEPTION THROW WHEN A DB2 ERROR OCCURS | |||||||||||||||||||||||||||||||||||||
![]() |
|||||||||||||||||||||||||||||||||||||
APAR status Closed as program error. Error description Problem : The customer has DB2 XA enironment with one local and one remote application database. He shuts down the remote application database, and the transaction fails. Before applying pq55352 (and subsequently pq55402), an error was returned to the servlet. Until DB2 apar JR16724 was applied, the biggest problem was that at pq48877 the customer received an exception, but the DB2 layer never recovered the XA transaction. . With the DB2 apar and PQ48877 the customer application recovers. But if they apply pq55402 they still see the behavior where with the remote database down, the servlet just hangs, and no exception is every thrown.Local fix Problem summary **************************************************************** * USERS AFFECTED: WebSphere Application Server users of * * Connection Management * **************************************************************** * PROBLEM DESCRIPTION: Possible hangs when processing * * StaleConnectionExceptions. * * Similar to PQ55402. * **************************************************************** * RECOMMENDATION: * **************************************************************** Possible hangs when processing StaleConnectionExceptions. Connections become unusable and do not recover. This is similar to PQ55402 but for a different case - JTA Enabled or XAConnection.Problem conclusion The code path for JTA was fixed so that it doesn't hang when a stale connection occurs.Temporary fix Customer has the Fix and it works.Comments
