We are seeing that XCOM STC is using/calling v2.1 of Syncsort instead of current release v3.1.
When an installation of XCOM is done, is there a job that assemble/links with the current Syncsort version or is there a parameter for what version is current?
Release : 12.0
XCOM itself does not use Syncsort or any other SORT product.
The detected Syncsort usage must be because Syncsort is being used in an XCOM batch job or it is being used in an XCOM user exit.
Check if any XCOM batch jobs have JCL which reference Syncsort or if the source code for XCOM user exits has been customised to reference Syncsort.
For reference the XCOM User Exits doc. page is: XCOM™ Data Transport® for z/OS 12.0 > Using > User Exits
