How to disable an obsolete Processor Group

Issue/Introduction

Whenever you have to disable an obsolete Processor Group in Endevor, please follow the information provided below:

Resolution

1.  Update the Type Definition to point to the new processor group.

2.  Run the ALTER command to search and edit the elements to remove the obsolete processor group and assign them the new one. 

In the below example, the command will search:
- for all Elements in the Environment PROD,
- for all Systems and Subsystems,
- Type of COBOL and
- all stages.  
- If the element also has processor group COBOL43 it will be selected to be changed to processor group COBOL63.  

Example:

ALTER ELEMENT '*'
  FROM ENVIRONMENT 'PROD' SYSTEM '*' SUBSYSTEM '*'
    TYPE 'COBOL' STAGE '*'
  REPLACE PROCESSOR GROUP COBOL43 WITH COBOL63
  OPTIONS NOUPDATE ELEMENT                        
 .    

The command is set up initially with OPTIONS NOUPDATE ELEMENT. This will force NO changes to be done, it will only show the Elements that will be changed. To actually update the Elements, change NOUPDATE to UPDATE.  

The ALTER processor group will not change how the existing element selects the delete processor. So only the default processor group will be changed.  
Note that the ALTER command requires SMF recording to be turned on.

3.  Update the processors in the "old processor group" (the one that is being made obsolete) to *NOPROC* .

4.  When you are ready to move forward with the "new" processor group, all you have to do is delete the old one.
