    Can we convert ACCESS method from VSAM to OSAM during CA FFOR IMS using OLDDBD ?

    I am getting U4021 abend during conversion and my DBDSRC is not using any exit routines,

    whether its problem related to DBDSRC ?

    Thanks for the reply!!

     

    Can we convert VSAM to OSAM using other CA IMS Online Re-org Utilities(FUNCTION=BATCHREORG) apart from CA FFOR (FUNCTION=REORG)?

    Or We have to convert it using CA IMS Offline Utilities?
