We install our product via SMP/E, and of course provide sample JCL to do so.
Those jobs currently specify VOLSERs everywhere via a VOLSER variable, with the
expectation that customers will further configure the jobs for their
installation, especially if using SMS.
I'd like to make it simpler. Looking at the jobs, there are three places that
the VOLSER gets used.
The ALLOC job contains:
// VOL=SER=&VOLSER.,
(on a bunch of DDs) and
VOLUMES(&VOLSER) +
(on a bunch of DEFINE CLUSTER statements) and
VOLUME(&VOLSER).
(on a bunch of ADD DDDEF statements)
and the RECEIVE jobs each have a single instance of:
//SMPTLIB DD UNIT=&UNIT,VOL=SER=&VOLSER,SPACE=(CYL,(10,10,100))
I'm wondering if it seems plausible to do something like add a variable named
(say) VSORSC (that's "VolSer OR StorClas"). The value of this would be (doh) a
VOLSER or storage class name, plus another variable indicating whether it's a
VOLSER or storage class. Then our code would set and use more variables in the
appropriate places,e.g.:
If using VOLSERs:
SD1 gets set to VOL=SER=&VSORSC
SD2 gets set to VOLUMES(&VSORSC)
SD3 gets set to VOLUME(&VSORSC)
If using STORCLAS:
SD1 gets set to STORCLAS(&VSORSC)
SD2 gets set to ??
SD3 gets set to ??
The question is what SD2 and SD3 should be set to when using STORCLAS; I don't
know (maybe just STORCLAS(&VSORSC) again??). And those with more knowledge of
SMS and SMP/E than me (I can spell both about two out of three times) may say
"Nah, this is pointless because there are too many other possibilities for this
to even come close to making sense".
Obviously I'm ignoring the case of them wanting to use VOLSERs but with stuff
spread across multiple volumes, or using SMS but wanting stuff in different
storage classes; those are possible but seem like the advanced class--those
folks won't have a problem just updating the jobs directly.
Plausible? Or fool's errand?
