Hi There,
Background:
We have an IMS database which is no longer being used actively.
It has been decided to decommission the database. This has necessitated changes in the programs which use that database.
Question:
The program which accessed the database uses a PSB which has the PCB details for the other IMS databases which we would need. Say, DB1 is what we are decommissioning and the PSB also has DB2, DB3 which we would require to use.
If we start commenting out all the IMS calls for DB1 within the program, the changes to be done are huge.
Given this scenario, what would be the simplest solution to this?
Any inputs will be greatly appreciated.
Thanks in advance.
Regards,
Raghavendra |

There is no simple solution... just donkey work
also You need to consider all the references to the fields relative to the decommissioned DB and used in all the programs.. |

A quick and dirty trick could be to create dummy/empty copybooks for all the structures related to the DB in question
and run compilations of all the programs involved in order
to have a the error listing for all the variables used but not defined
and keeping doing it until You get a error free compilations |

Since you wont be using the IMS DB, the logic and functionality of the program changes drastically.
How about doing analysis and think about re-designing the programs, and some times the pogram may become obsolete. |
