As much as we may hate to admit it, problems do sometimes arise in the ZMF Server started task that may lead to an abend (and I hasten to stress that these are not always Serena's fault!). Also, back in the dim and distant past that coincided with the release of ZMF 7.1, the recommended started task dump file contained in the SERVER sample CNTL member changed from the tried and trusted:
//SYSUDUMP DD SYSOUT=* *Abend list
to the new (and slightly mysterious for some):
//SYSMDUMP DD DISP=(MOD,CATLG,CATLG), * SYSMDUMP // DSN=somnode.SERCOMC.SYSMDUMP(+1), // UNIT=SYSDA,SPACE=(CYL,(200,100),RLSE), // DCB=(DSORG=PS,RECFM=FBS,LRECL=4160,BLKSIZE=4160)
Many of our customers are comfortable with SYSMDUMPs. However, if you are unfamiliar with this format, have never made the change to your started tasks’ JCL, are wondering why this happened, how these should be handled or are interested in some of the common mistakes we see customers making with them, then please read on.
