Installing CA Disk Under CA ACF2 › Installing the CA ACF2 Interface

Installing the CA ACF2 Interface

Perform the following procedure to install the CA ACF2 Interface.

To install the CA ACF2 Interface:

1. Activate the CA Disk CA ACF2 Interface by specifying sysparm ACF2SUPP with a value of Y in the SYSPARMS member of the parmlib data set.
2. Review access to data set names VTOC.volser and DMSOS.Vvolser. If you use the SELECT VTOCS DSCL statement, CA Disk backs up the VTOC of each volume processed, tracking this information by the esoteric data set name VTOC.volser, where volser is the volume on which the VTOC resides.

   If you create volume-level backups with the VBACKUP command, CA Disk backs up each volume, tracking this information by the esoteric data set name DMSOS.Vvolser, where volser is the volume being backed up.

   BACKUP, VBACKUP, and IXMAINT functions each query any CA Disk Security Interfaces for authority to process these names.

   If you plan to use the SELECT VTOCS DSCL statement, or the VBACKUP command, make sure that your BACKUP, VBACKUP, and IXMAINT functions can each access this fictitious data set name.

3. Examine the following special considerations for implementation of CA ACF2 in multiple-CPU shops.

If the ACF2SUPP sysparm is specified with, a value of Y and CA ACF2 is not active on the CPU on which CA Disk is running, CA Disk issues an appropriate message and abend. This prevents CA Disk from processing data sets that is normally protected by the security system. This situation sometimes occurs in installations that have CA ACF2 installed only on some of the CPUs that CA Disk is running on.

To avoid this problem, specify sysparm ACF2FORC with a value of Y to indicate that CA Disk continues processing even if CA ACF2 is not installed on the system on which it is running. If ACF2FORC is specified as Y and CA ACF2 is not active on the system, no security checking is performed
