I’m working for a client that just laid-off their only z/OS Systems
Programmer after 26+ years of loyal service. I inherited his workload,
including a proposal to change to their JES2 spool setup. They are a
retailer and will be going into their peak season soon, so they want to
insure that they won’t run out of JES2 resources (Spool space, JQE’s, TG’s
etc.)
They currently have 4 3390-3’s being used for spool space, with three more
volumes available for adding if need be. They have two lpars in a parallel
sysplex, but have not plexed their JES’s, so this is a single JES2 MAS
definition we’re dealing with. Spool related JES2 parms are as follows:
SPOOLDEF BUFSIZE=3992, /* Buffer size 1944-3992 */
DSNAME=SYS1.HASPACE, /* Spool data set name */
FENCE=NO, /* Force to Minimum volume ? */
SPOOLNUM=32, /* Max. Number of spool volumes */
TGBPERVL=5, /* track groups per volume in blob */
TGNUM=81440, /* Fits TGMs into 4K Page */
TGSIZE=36, /* Buffers/Track Group */
TGSPACE=(MAX=32576, /* @R4 */
WARN=80), /* @R4 */
TRKCELL=3, /* Buffers/Track-cell */
VOLUME=SPL00 /* Spool Volume Serial @MVS1 */
…
JOBDEF JOBNUM=10000, /* Job Queue Size */
…
Now they are at z/OS 1.4 and according to the JES2 doc at that level, some
of these parameters are old or obsolete. A @DSPOOLDEF shows the following:
$DSPOOLDEF
$HASP844 SPOOLDEF 385
$HASP844 SPOOLDEF BUFSIZE=3992,DSNAME=SYS1.HASPACE,
$HASP844 FENCE=(ACTIVE=NO,VOLUMES=1),GCRATE=NORMAL,
$HASP844 LASTSVAL=(1998.081,08:29:40),RELADDR=NEVER,
$HASP844 SPOOLNUM=32,TGSIZE=36,TGSPACE=(MAX=81440,
$HASP844 DEFINED=66700,ACTIVE=66700,PERCENT=32.5772,
$HASP844 FREE=44971,WARN=80),TRKCELL=3,VOLUME=SPL00
Any ideas as to what I need to change? It’s been decades since I’ve played
around with JES2 parms, so any help would be most appreciated.
