Connecting the IMS attachment facility to a second Db2 subsystem

After you install a second Db2 subsystem on the same operating system, you should connect the IMS attachment facility to that subsystem.

Procedure

To connect the IMS attachment facility:

  1. For separate libraries, change the STEPLIB DD statement in your startup procedure to refer to the new libraries.
  2. For separate libraries, change the DFSESL DD statement in your startup procedure to refer to the new libraries.
  3. Define a new subsystem name, language interface token (LIT), and command recognition character (CRC).
  4. Define a new language interface and reassemble.
  5. In the linkage editor JCL, specify the library that contains the new language interface.
