APAR status
Closed as program error.
Error description
When a thread that is paricipating in globally coordinated transactions with IBM MQ and DB2 closes down you may see an error reported. The error is reported in the IBM MQ error logs because IBM MQ is the transcation manager used, by IBM Intergarion Bus and App Connect Enterprise, to coordinate global transactions with DB2. The error reported by IBM MQ is XAER_PROTO (-6) on xa_close() and it will refer to the DataFlowEngibe process. The error can occur when a thread reaches its maximum 'database connection idle' time and attempts to disconnect.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: All users of IBM App Connect Enterprise V11 or V12, or IBM Integration Bus V10, who use globally coordinated (XA) transactions with a Db2 database. Platforms affected: Windows on x86-64 platform, Solaris SPARC platform, Solaris x86-64 platform, Linux on zSeries platform, Linux on x86-64 platform, Linux on Power platform, HP-UX Itanium platform, AIX **************************************************************** PROBLEM DESCRIPTION: When a thread that has been involved in globally coordinated transactions with a Db2 database is released, because it has become idle, there is the possibility that an XAER_PROTO (-6) error can be reported on the xa_close call. If this error has occurred it will be reported in the IBM MQ queue manager error logs as IBM MQ is coordinating the global transactions.
