Resolution

A1.
There are some examples of the CA DB2 Products that work with the parameters defined in SETUP00 member.
(If you want a more detailed answer then we have to open a separate Case for the particular CA DB2 Product.)
 
 - Some of the CA DB2 Utilities (Fast Unload, Rapid Reorg...) and Log Analyzer work with the values of SYSADM and SYSADM2 when they call PLR Log Reader to access the DB2 Log.

 - CA SYSVIEW for DB2 access the SETUPxx to know the XMANID to connect to Xmanager/Xnet. Or to read the ZPARM module ZPARMLIB and ZPARMMEM parameters and display their values.

Obviously Post-Install Tasks are the most use of the SETUPxx as when you run these tasks there is not an environment defined so you need to take the values from SETUPxx.

A2.
The ISFP00 is only used in Post-Install Task 'INS Bind Product Packages and Plans', SSID0002 Job.
