Question:
In the Overview Guide it says "CA Top Secret uses its own queuing and locking mechanism and does not issue any hardware reserves. Because of this operation, the files should be in the GRS exclusion tables and there are not QNAMES necessary for MIM." We use GRS and this does not say exactly which files can be excluded. Would you please tell be which ones that applies to? (PLUS this information should be in the installation manual not the overview or the users guide.)
Answer:
The following CA Top Secret datasets should be in the GRS exclusion tables: 

- The primary security files (BDAM and VSAM) 
- The VSAM AIX and VSAM PATH files (if sharing security file) 
- The mirror security files BDAM and VSAM (if using this feature) 
- The backup security files (BDAM and VSAM) 
- The audit file(s) 
- The recovery file 
- The CPF recovery file 
- The RCACHE VSAM Cluster (This is an optional file used for R_cacheserv hardening for USS) 

The QNAME for TSS is SYSDSN. 

There are 2 ways to add these: 

1) RNLDEF RNL(EXCL) TYPE(SPECIFIC) QNAME(SYSDSN) RNAME(tss.<<file>>) 

where <<file>> is the dataset name for the secfile, audit, recovery file etc. 

2) Or, if you have a generic naming standard that matches the TSS files, you can add a generic entry 

RNLDEF RNL(EXCL) TYPE(GENERIC) QNAME(SYSDSN) RNAME(tss.) 

where ‘tss.’ is the prefix of the TSS files. For example, if all of your TSS files start with TSS.R160.SYSABCD.filename, you can specify RNAME(TSS.R150.SYSABCD.) 

TYPE(SPECIFIC) means that you specify the complete dataset name. 
TYPE(GENERIC) means that you specify high level qualifiers and all datasets matching the qualifiers are excluded.
