Issue/Introduction

How does the INVAL command with UTIL utility help when one application generation record gets corrupted? 

Environment

Release : 11.4 & 12.0

 

Resolution

The command INVAL can be used in UTIL mode to invalidate just this generation of the application. 
                                                                    
The invalidated generation of the application will no longer be available to ESP task upon its startup.

This generation will be ignored and no scoreboard entry will be built (and other internal structures). It will not delete the record from the APPLFILE or JOBINDEX. For ESP processing this generation does not exist anymore (after restart of ESP).

Note:
- It can still show on LAP command until it's overwritten by more current generations. 
- If this generation on its completion was supposed to post some other generation, it will not happen and it has to be done manually using a command (i.e. UWA).
- It won’t affect the posting of externals if APPL has POST_OLDEST coded.
