Can the same JCL library be used by more than one CA7?
Yes. CA7 supports PDS, PDSE, CA PANVALET, CA Librarian, and CA Endevor libraries for use as JCL libraries for job selection. These libraries can be used by multiple CA7 instances and are accessed DISP=SHR during job selection. For CA PANVALET, CA Librarian, and CA Endevor libraries please see required Initialization File JCL statement keyword DSORG in the Systems Programming Guide.
