Error description
Provide a mechanism to disable one-phase commit optimization
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server * **************************************************************** * PROBLEM DESCRIPTION: Provide a mechanism to disable * * one-phase commit optimizations for * * JTA transactions. * **************************************************************** * RECOMMENDATION: * **************************************************************** If a JTA transaction involves a single resource, or, if during prepare all but the last resource votes read-only, the WebSphere Application Server Transaction Manager performs a one-phase commit optimization. There is currently no mechanism to disable the one-phase optimization.
Problem conclusion
The one-phase commit optimization can be disabled by setting the JVM System Property com.ibm.ws.Transaction.disableOnePhaseCommitOptimisation to a value of true. The default value is false, in which case the behaviour remains unchanged and one-phase commit optimizations are performed as before the APAR. The fix for this APAR is targeted for inclusion in fix pack 8.5.5.18 and 9.0.5.5.
