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.
