Is the format of the SnapShot Copy produced by Quick Copy for Db2 for z/OS (PQC) standard or concurrent format?
SNAPSHOTACCES YES will produce a standard Db2 imagecopy and register it in SYSCOPY as a standard DB2 image copy.
SNAPSHOTACCESS INSTANT will create a copy with a format similar to CONCURRENT COPY but only PQC and Fast Recover for Db2 for z/OS (PFR)
will know about this copy. It should NOT be registered in SYSCOPY since it is basically a VSAM DATASET dump (complete snapshot).
