Preparing your system to use the DB2 Attach Facility

To prepare your system to use the DB2® Attach Facility, you must perform two tasks.

To use the DB2 Attach Facility:

  1. Add the attachment facility definition to the IMS PROCLIB data set.
    Use of the DB2 Attach Facility requires that a subsystem member (SSM) be defined in IMS.PROCLIB. If an SSM member does not already exist in IMS.PROCLIB, you must create one. The SSM contains an entry for the Db2 for z/OS® system with which IMS and the application program communicate. All Java™ dependent regions in IMS access a single Db2 for z/OS system.
  2. Make the Db2 for z/OS RESLIB available to the IMS JMP and IMS JBP regions.
    After defining the attachment facility, you must provide the Java regions in IMS with access to the Db2 for z/OS RESLIB. In the JCL for the JBP and JMP regions types, add the Db2 for z/OS library definition using the DFSDB2AF DD statement, which points to the Db2 for z/OS libraries that contain modules used by RRSAF. The Db2 for z/OS libraries must be APF-authorized.
