Error description
CSQX053E CSQXFFST Error information recorded in CSQSNAP data set CSQX027E CSQXRESP Unable to get storage, RC=00000000 CSQX053E CSQXFFST Error information recorded in CSQSNAP data set : : CSQX027E CSQXRESP Unable to get storage, RC=00000FC9 CSQX053E CSQXFFST Error information recorded in CSQSNAP data set IEA794I SVC DUMP HAS CAPTURED: DUMPID=002 REQUESTED BY JOB (xxxxCHIN) DUMP TITLE=xxxx,ABN= 5C6-00E70071,C=R3600.701.CHIN CSQX027E CSQXRESP Unable to get storage, RC=00000FC9 CSQX053E CSQXFFST Error information recorded in CSQSNAP data set IEA794I SVC DUMP HAS CAPTURED: DUMPID=002 REQUESTED BY JOB (xxxxCHIN) DUMP TITLE=xxxx,ABN= 5C6-00E70071,C=R3600.701.CHIN LOC=CSQXRCTL.CSQXBPFR+0040E Change team confirmed that the CSQX027E message is being erroneously issued due to the presence of the CSQXDBG DD card That is, there is no shortage of storage in the CHIN; the message is being issued due to the buffer pool checking code setting a return code when it finds an orphaned buffer (orphaning of the buffer is due to the PI13042 problem).
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 0 Modification 1 * **************************************************************** * PROBLEM DESCRIPTION: When running with the chinit debug * * DD card CSQXDBG enabled, any detected * * problems with storage may also result * * in a CSQX027E error (UNABLE TO GET * * STORAGE) where no storage shortage * * exists. * **************************************************************** * RECOMMENDATION: * **************************************************************** With the CSQXDBG DD card enabled, additional checks are performed on the consistency of buffer blocks and chains. In the event of a problem being discovered, this is reported via an FFST as intended. When a problem is reported, the return code from the original storage allocation or free operation may be overwritten by the result of the buffer checking operation. This may make the calling function believe that the storage operation failed when it in fact succeeded.
Problem conclusion
Processing has been amended to ensure that the return code from the buffer checking operation does not overwrite the return code for the initial storage operation. 010Y CMQXRSRV CSQXCCMX CSQXCCM2 CSQXCMEM CSQXRSTM
