Converting to DFSMSrmm from ASG-ZARA or AutoMedia

330 Converting to DFSMSrmm from ASG-ZARA or AutoMedia

This is done by permitting user ID VSM8HSC (STC userID) control access as

shown in Example 7-23.

Example 7-23 Permit HSC to RMM resources

PERMIT STGADMIN.EDG.MASTER ACCESS(CONTROL) ID(VSM8HSC)

See Security Server RACF Security Administrator’s Guide, SA22-7683 for

more information about the resources defined in the RACF FACILITY class.

4. Protect VTCS commands.

Define a profile in the OPERCMDS class for all VTCS commands. You can

use a RACF RDEFINE OPERCMDS as shown in Example 7-24.

Example 7-24 ADD an OPERCMDS resource

RDEFINE OPERCMDS subsystemname.VT UACC(NONE)

5. Allow user SAM15 update access to all VTCS commands you have

previously defined as shown in Example 7-25.

Example 7-25 PERMIT VSM to OPERCMDS

PERMIT subsystemname.VT CLASS(OPERCMDS) ID(SAM15) ACC(UPDATE)

7.2 Parallel processing

The timing of the DFSMSrmm update to its CDS during OPEN processing is

such that any volumes rejected by the vendor system should not result in

updates to the DFSMSrmm CDS.

Also, the timing of the DFSMSrmm reject of a tape is such that recording by

AutoMedia or ASG-ZARA may not occur if DFSMSrmm rejects a volume.

Therefore, parallel running problems are unlikely to be the result of volume

rejection and control by one system or the other. More likely, the differences in

inventory management functions such as expiration and retention control cause

the problems. DFSMSrmm’s uncataloging of tape data sets can cause the other

vendor system to return a tape to scratch, and vice versa.

Caution: VTCS has an automatic interface to notify DFSMSrmm when a VTV

becomes scratch but DFSMSrmm does not notify VTCS when unscratching a

VTV by changing the volume status to non-scratch. If this is done, you must

also run the HSC SLUADMIN utility to unscratch the VTV for VTCS.

Otherwise, you may encounter a mount failure when VTCS attempts to

service a scratch mount request.
