Managing the environment
Requirements for managing your recovery environment include ensuring that data sets and areas that are to be recovered are defined to DBRC and are available on the system running IMS Database Recovery Facility.
All required resources must be in the RECON, and DBDLIBs must be available.
In an IMS-managed ACBs environment, the IMS catalog must be available instead of DBDLIBs. Also, the IMS catalog must be registered in the RECON.
