z/OSMF Network Configuration Assistant import function

The z/OS AI Services workflow creates a flat file with the AT-TLS policy. We have no way of importing that file into z/OSMF NCA without entering all the information manually. We need the ability to import that file into z/OSMF NCA.

zERT - Show a hint when zOSMF NCA will generate multiple policy agent rules

As there is no 1:n mapping from the zERT rules to the implementable policy, zERT will generate as many rules as required and append a suffix like ~1, ~2, ~n. However when coding those rules in the zOSMF NCA GUI there is not hint that the resulting...

Create a workflow for zERT Provisioning - Database, RACF

At the moment, one has to customize members (IZUZNADT, IZUZNADI, IZUNASEC ) in SYS1.SAMPLIB to provision a database for zERT and grant access to zERT. My idea is to use a workflow which would allow to do the same but inside a z/OSMF workflow.
