Can the RDT (Resource Descriptor Table) entry for IBMFAC be changed from NOMASK to MASK safely?
Release: Component: TSSMVS
NOMASK can be changed to MASK in the RDT for IBMFAC, however, there is a procedure to do this. It's not as simple as just changing the attribute because existing permits for this class could be affected.
The procedure is: 1) Revoke ALL permits in the IBMFAC resource class. (Issue TSS WHOOWNS IBMFAC(*)
to see all ownerships and then
TSS WHOHAS IBMFAC(xxxx)
for each 'xxxx' that shows up in the WHOHAS output.
Save the WHOOWNS and WHOHAS output.)
TSS REVOKE(acid) IBMFAC(xxxx)
2) Remove ALL ownerships in the IBMFAC resource class.
TSS REMOVE(dept) IBMFAC(xxxx) for each 'xxxx' that shows up in the TSS WHOOWNS IBMFAC(*) output in step 1.
3) If SECCACHE is not active, skip to step 4.
If SECCACHE is active, SECCACHE must be turned off before changing NOMASK to MASK in the RDT.
a. Find the SECCACHE control option in your TSS parameter file. Note the settings for when SECCACHE is reactivated.
