Source code for the CA Disk SVC is supplied in member ADSMVS60 of the CCUWSAMP library. The four exclusion tables are supplied in members ADSOPPGM, ADSOPDSN, ADSOPJOB, and ADSOPVOL. The tables can be used to exclude from DSCB updating any combination of data sets, DASD volumes, jobnames and programs. The program exclusion capability is recommended for use when running CA Disk jobs. This technique prevents a CA Disk management job from causing a data set to appear to have been used. The table code has each table initialized with either a real or dummy entry to illustrate how entries are defined. The CA Disk SVC is provided with the tables already linked. If they are modified, they must be re-assembled and linked into the CA Disk SVC.
Note: The activating zap is such that the CA Disk SVC replaces the MVS SU 60 update code (that is, if the SVC is activated, SU 60 decisions are deactivated).
