APAR NUMBER: PJ40972 PRODUCT: z/TPF FUNCTIONAL AREA: MQS SUPPORT SHIPPED IN PUT: 10 ABSTRACT: With PJ30737, writing z/TPF WebSphere MQ sweeper trace log entries to a z/TPFCS BLOB may result in an OPR-9323 (system error 009323). PACKAGE CONTENTS: Source Segments: (C) base/rt/cmqmgc.cpp Object Only Binaries: None. Configuration Independent Binaries: (C) base/lib/libCMQS.so (C) base/load/CMQS.so (C) base/obj/cmqmgc.o Support Files: base/lst/CMQS.map base/lst/cmqmgc.lst OTHER BINARIES TO BUILD: NO None. COMMENTS: With the addition of PJ30737, z/TPF WebSphere MQ sweeper trace enhancements, queue trace entries are written to a z/TPF collection support (z/TPFCS) BLOB. This allows the trace entries to be saved over an IPL. If two processes attempt to write to the same Trace Log BLOB that might result in system error 009323 (MQSERIES UNEXPECTED TO2 ERROR) out of segment cmqmgc.cpp with the following diagnostics: "-write Trace Log BLOB error", the persistent identifier (PID) of the BLOB, and "-6 - UPDATE SEQUENCE COUNTER MISMATCH". This occurs because the z/TPFCS BLOB is not locked and updates are managed by the use of a sequence number. The routine that writes the trace data reads the BLOB then writes the update; if another process updates the BLOB after it is read and before it is written, a z/TPFCS sequence error mismatch will result.
SOLUTION: The z/TPF WebSphere MQ sweeper trace has been updated to check for a sequence error. If a sequence error is detected, the BLOB is re-read and re-written until it completes without error. COREQS: NO None. MIGRATION CONSIDERATIONS: NO None. BUILD COMMANDS AND INSTRUCTIONS: YES #maketpf commands for linux maketpf -f CMQS cmqmgc.o maketpf CMQS link TPF_VERIFY_LINK_REFS=NO maketpf CMQS link UPDATED INFORMATION UNITS: NO None.
