IIRC - Not difficult if you are not using anything unique to CA Sort. All sort
products (DFSORT, SYNCSORT, and CA SORT) are mostly interchangeable. The
PGM=SORT is the same in all three and I think the Control Cards are mostly the
same. Sort is one product where interchangeability seemed to rule.
If DFSORT is not installed as your primary z/OS sort product do one of the
following:
Add the DFSORT SORTLPA library to the link pack area list; then add the
DFSORT SICELINK library to the link list.
OR
Add the DFSORT SICELINK library to the link list; then add the DFSORT
SORTLPA library to the link list.
Important: If any non-IBM primary sort product is installed in the link
list, install DFSORT in the link list, in system search order.
Recommendation: If any non-IBM primary sort product is installed in the
link pack area, add the DFSORT libraries to the link list.
For testing, you can
Add the DFSORT SICELINK library to the JOBLIB statement; then add the
DFSORT SORTLPA library to the JOBLIB statement.
Add the DFSORT SICELINK library to the STEPLIB DD statement; then add the
DFSORT SORTLPA library to the STEPLIB DD statement.
Add the DFSORT modules to a private library that is equivalent to one of
the above configurations.
You may need to update IFAPRDxx in SYS1.PARMLIB to enable DFSORT.
Review any configuration done in CA Sort with ICEMACx members. I think you
need a usermod for these.
But you can test with STEPLIBs for a few of your sort jobs. Once you know those
work, you can probably just change the CA Sort to be below DFSORT in LINKLST
and LPALST
I think the DFSORT libraries are part of the system install so you may already
have them in your system.
You may just need to review how to locate them and plan how to swap out the CA
Sort information.
Review the SVC 17 ESR and see if that is still needed.
Review any configuration and see how ICEMACx may need to be updated.
I think IBM Support may have info on this process.
