Message Format Services (MFS) Operations

The treatment of MFS (Message Format Services) is a little different from that of the PSBs and DBDs. The COPE system can access a copy of the production system Format Libraries. Whenever a change is made to a format definition or a new format introduced, it must be imported into the Logical System that uses it. If a format is not imported into a Logical System, COPE will use the ‘production version’ of the format.

Typically, on a new COPE installation, no formats are imported.

Adding MFS into COPE

You only import MFS into COPEthat you wish to change. It is not necessary or desirable to import all MFS into COPE.

Follow this procedure to add MFS source into COPE.

1. Go to COPE Option 2 (Import and Generate) (COPE Development System Import - MFS).
2. Update the Logical System field.
3. Update the Input dataset name field to point to the MFS source.
4. Enter Option MFS.

5. Press Enter.

    COPE Development System Import - MFS

   

6. Place an S next to the MFS source member you wish to import (COPE Development System Import - MFS)

7. Press PF3 twice.Select MFS Source Member

   

8. Submit and run the job that is generated.
   It will update COPE cross-reference tables and submit a job that will compile the MFS.

Changing MFS Source in COPE

Follow this procedure to update MFS source within COPE.

1. Go to COPE Option 3 (Update/Copy/Move/Generate) (COPE Development System Dynalloc Update/Generate).
2. Update the Target Logical System field as appropriate.
3. Enter MFS in the Option field.
4. Press Enter.
   COPE Development System Dynalloc Update/Generate
   
5. Put an E next to the MFS source you wish to update (Edit MFS Source).
6. Press Enter to display an ISPF edit session for the MFS source.
   Edit MFS Source
   
7. Update the MFS source as appropriate and press PF3.
8.  Place a G next to the MFS source you wish to generate (Generate MFS Source).
   Generate MFS Source
   
9. Press Enter.
   Note – the prompt field now shows COMPILE (Generate MFS Source -COMPILE).
   Generate MFS Source -COMPILE
   
10. Press PF3 to review the generated JCL.
11. Submit and run the job that is generated.
    This job will update COPE tables and submit a job which will run the MFS generation to the TEST format library.

Deleting MFS Source in COPE

Follow this procedure to update MFS source within COPE.

1. Go to COPE Option 3 (Update/Copy/Move/Generate) (COPE Development System Dynalloc Update/Generate).
2. Update the Target Logical System field as appropriate.
3. Enter MFS in the Option field.
4. Press Enter.
   COPE Development System Dynalloc Update/Generate
   
5. Put an D next to the MFS source you wish to delete (Delete MFS Source).
   Delete MFS Source
   
6. Press Enter.
   Note – the prompt field now shows DELETED (MFS Source - DELETED).
    MFS Source - DELETED
   
7. Press PF3 to review the generated JCL.
8. Submit and run the job that is generated.
   This job will update the COPEtables and submit additional jobs which will delete the MFS and update additional COPE tables.
