I would like to know if SYSGEN has to be performed for the program that executes in batch using BMP IMS parameter on DFSRCC0 utility. I assume that the SYSGEN is process that relates to the PSB and nothing to do with the application program created newly.
For instance below is my JCL, it uses PGM-A whereas the PSB-B is different name and an existing one. Do I need to perform SYSGEN for this or not required.
You can use an existing PSB as it is... for newly created program...in your case the the program that uses PSB-B should be also a BMP...you can have the same structure of in PROCEDURE DIVISION USING ......(PCB(S))
its always good to use the PSB name as same as program name..
I guess SYSGEN not required...can you provide more information on SYSGEN and relation with PSB that you are refering to.....
