The following scenario illustrates how you could configure the RRSF network shown in Figure 1 .

Figure 1. An RRSF network containing two multisystem nodes. NODEAB and NODEEFG are both multisystem nodes.

In this network, systems MVSA and MVSB share a RACF® database, and are configured as member systems of multisystem node NODEAB. MVSA is the main system on NODEAB. Systems MVSE, MVSF, and MVSG share a RACF database, and are configured as member systems of multisystem node NODEEFG. MVSE is the main system on NODEEFG.

1. Create a shared RACF parameter library for MVSA and MVSB, and set up MVSA and MVSB to invoke a common member of the parameter library, IRROPTAB, at initialization. (See The RACF parameter library for information on how to do this.) Add the following commands to IRROPTAB to configure MVSA and MVSB as member systems of multisystem node NODEAB:

   TARGET NODE(NODEAB) SYSNAME(MVSA) LOCAL MAIN PREFIX(SYS1)
      PROTOCOL(APPC(LUNAME(MF1AP001)) WORKSPACE(VOLUME(TEMP01)) OPERATIVE
   TARGET NODE(NODEAB) SYSNAME(MVSB) LOCAL PREFIX(SYS1)
      PROTOCOL(APPC(LUNAME(MF2AP001)) WORKSPACE(VOLUME(TEMP01)) OPERATIVE

2. Add the following commands to IRROPTAB to configure NODEEFG as a remote multisystem node for NODEAB:

   TARGET NODE(NODEEFG) SYSNAME(MVSE) MAIN PREFIX(SYS3)
      PROTOCOL(APPC(LUNAME(MFEAP001)) WORKSPACE(VOLUME(TEMP01))
   TARGET NODE(NODEEFG) SYSNAME(MVSF) PREFIX(SYS3)
      PROTOCOL(APPC(LUNAME(MF6AP001)) WORKSPACE(VOLUME(TEMP01))
   TARGET NODE(NODEEFG) SYSNAME(MVSG) PREFIX(SYS3)
      PROTOCOL(APPC(LUNAME(MF7AP001)) WORKSPACE(VOLUME(TEMP01))

3. Create a shared RACF parameter library for MVSE, MVSF, and MVSG, and set up MVSE, MVSF, and MVSG to invoke a common member of the parameter library, IRROPTEG, at initialization. (See The RACF parameter library for information on how to do this.) Add the following commands to IRROPTEG, to configure MVSE, MVSF, and MVSG as member systems of multisystem node NODEEFG:

   TARGET NODE(NODEEFG) SYSNAME(MVSE) LOCAL MAIN PREFIX(MSN.SYS3)
      PROTOCOL(APPC(LUNAME(MFEAP001)) WORKSPACE(VOLUME(D79PK5))
   TARGET NODE(NODEEFG) SYSNAME(MVSF) LOCAL PREFIX(MSN.SYS3)
      PROTOCOL(APPC(LUNAME(MF6AP001)) WORKSPACE(VOLUME(D79PK5))
   TARGET NODE(NODEEFG) SYSNAME(MVSG) LOCAL PREFIX(MSN.SYS3)
      PROTOCOL(APPC(LUNAME(MF7AP001)) WORKSPACE(VOLUME(D79PK5))   

4. Add the following commands to IRROPTEG to configure NODEAB as a remote multisystem node for NODEEFG:

   TARGET NODE(NODEAB) SYSNAME(MVSA) MAIN PREFIX(MSN.SYS1)
      PROTOCOL(APPC(LUNAME(MF1AP001)) WORKSPACE(VOLUME(D79PK5)) OPERATIVE
   TARGET NODE(NODEAB) SYSNAME(MVSB) PREFIX(MSN.SYS1)
      PROTOCOL(APPC(LUNAME(MF2AP001)) WORKSPACE(VOLUME(D79PK5)) OPERATIVE

5. Issue the following command on systems MVSA and MVSB, to cause the commands in IRROPTAB to run:

   SET INCLUDE(AB)

6. Issue the following command on systems MVSE, MVSF, and MVSG, to cause the commands in IRROPTEG to run:

   SET INCLUDE(EG)
