Problem summary
**************************************************************** * USERS AFFECTED: All Distributed Data Facility (DDF) users. * * Specifically those with remote client * * XA Transaction Manager environments. * **************************************************************** * PROBLEM DESCRIPTION: The following abends are reported * * during indoubt thread resolution * * processing that's initiated from a * * remote XA Transaction Manager * * environment: * * o 04E-00D3002E DSNLTRD :0014 * * o 04E-00D31010 DSNLCRSY:0005 * **************************************************************** * RECOMMENDATION: Apply corrective PTF when available * **************************************************************** Potential abends can occur during automatic indoubt thread resolution (Resync) processing that's initiated from remote XA Transaction Manager environments. The conditions are highly rare or intermittent because they only occur in the unlikely event that the remote XA Transaction Manager environment happens to initiate multiple concurrent automatic indoubt thread resolution sequences. The abends occur because Db2 "XA resync" processing continually acquires and releases latch serialization which may lead to a timing window opportunity for the indoubt thread knowledge (RLE) to be unexpectedly deleted by another resync event.
Problem conclusion
Db2 11/12 for z/OS is changed to maintain latch serialization for the duration of the XA related resync event.
