Enhancements for validating DBB toolkit setup/configuration

Please consult the thread at https://github.com/IBM/dbb-zappbuild/discussions/466 

I am often asked to validate things with regards to DBB/zAppBuild. Many of these tasks I manually do, though I have a few scripts of my own that do some of it. I realize that part of this inquiry is in regards directly to DBB and the database; but it has direct impacts to zAppBuild. This may be for a new client implementing DBB or for an upgrade of DBB to 2.x. In both scenarios zAppBuild is also in question.

How can I automate this?
Let me use Jazz as a simple example. When you go through the web wizard for the setup of Jazz, it requires you to input the required information to connect the database. It then has a Test Connection button. This validates that you have the correct database credentials, jdbc drivers, and the requisite environment settings.

I often need to validate the following items:
General DBB:

• DBB db2z database has correct RACF permissions.
• DBB_HOME is defined in /etc/profile or otherwise
• DBB toolkit has the correct permissions. i.e. /usr/lpp/IBM/dbb/bin and such are as they need to be.
• DB2 JDBC drivers
   

The idea should about extending the validation.groovy script to check:

• metadatstore connection
• assigned DBB role (btw - there is this a util available in https://github.com/IBM/dbb/tree/main/Utilities/PermissionCheck)
• ISPFExec / TSOExec configuration
• printing of the permissions of the toolkit

This also needs to be documented in the Host Configuration guide.
