Example 5: Reloading an HDAM database in an IMS managed ACBs environment

When the IMS™ management of ACBs is enabled, you can reload a database without specifying the DBD library on the IMS DD statement.

Use the following JCL example to reload a database in an IMS managed ACBs environment.

In this example:

DFSDF=CAT parameter is specified on the EXEC statement. This parameter specifies the DFSDFCAT member that enables IMS managed ACBs.
The name of the IMS.PROCLIB data set in which the DFSDFCAT member exists is specified on the PROCLIB DD statement.
The name of the SGLXLOAD library of IMS Tools Base is specified on the STEPLIB DD statement.
The keyword STAGING is specified on the DFSACBPD DD statement. This keyword specifies to reload with the pending changes from the staging data sets in IMS catalog.
IMS DD is not specified.

If all of the following conditions are met, the catalog database must be registered to the RECON data sets:

DBRC=YES
Database is a non-HALDB
IMS DD is not specified
