Error description
The EYUSTARTDB2THRD view ('DB2 threads in a CICS region') shows value as zero for field 'Maximum number of threads' even if the DB2entry has a 'threadlimit' specified. Other fields seems correct: 'Number of reserved threads' shows correctly the Protected thread defined for the DB2entry. The MAXTHREADS field is only set for PLAN and COMMAND threads. We inquire on DB2ENTRY and retrieve THRAEDLIMIT, but don't set the value in the DB2THRD resource. Problem is faced both in CICSTS41 (customer's environment) and in CICSTS42 environments.
Local fix
NA.
Problem summary
**************************************************************** * USERS AFFECTED: All CICSPlex SM V4R1M0 and V4R2M0 Users * **************************************************************** * PROBLEM DESCRIPTION: The EYUSTARTDB2THRD view ('DB2 threads * * in a CICS region') shows the value for * * 'Maximum number of threads' as zero, * * for pool, command, and entry threads, * * even if the DB2ENTRY and DB2CONN re- * * sources have thread limits specified. * * 'Number of current threads' might also * * contain zero, even though there are * * active pool, command, or entry threads. * **************************************************************** * RECOMMENDATION: After applying the PTF that resolves this * * APAR, all MASes must be recycled to pick * * up the new code. Note that regions do not * * need to be brought down and restarted at * * the same time. * **************************************************************** The EXEC CICS INQUIRE DB2CONN and EXEC CICS INQUIRE DB2ENTRY commands return thread limits and active thread counts as full word values. However the MAXTHREADS and CURTHREADS attributes of the DB2THRD resource table are half word fields. Module EYU0NQT5 (NQT5 - Query DB2THRD Resources) copied the high order half word of the value returned by the EXEC CICS INQUIRE com- mands into the DB2THRD resource table. NQT5 did not copy the DB2ENTRY THREADLIMIT value into the DB2THRD resource table.
Problem conclusion
Module EYU0NQT5 was modified to copy the low order half word of thread limits and active thread counts returned by CICS into the DB2THRD resource table. MAXTHREADS is now set for entry related DB2THRD resources.
