Resolution

There are some examples of the Database Management for Db2 for z/OS products that work with the parameters defined in SETUPxx member.
 
 - Some of the Database Management 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.
 - Sysview for Db2 accesses 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.


The ISFPxx member is only used in Post Install Task INS Bind Product Packages and Plans ssid0002 job.
