Steps to Implement CPF on systems 'A' and 'B'

  1. Verify CCI is installed.

  2. Define new APPLIDs to VTAM for CPF on both Systems.

  3. Create two CPF recovery files (one for each system).

  4. Create two CPF journal files (one for each system).

  5. Review and tailor the Top Secret CPF parameters on both systems. See examples at bottom.

  6. Review and tailor the TNG/CCI parameters on both systems. See examples at bottom.

  7. Review and tailor the TNG/ENF on both systems.

  8. Shutdown and restart the started task CAS9 to update CCI and ENF (this will active CCI).

  9. Modify the JCL for the Top Secret started task on both systems to point to the new CPF recovery and CPF journal files.

  10. Review and discuss Top Secret command keywords used with CPF.

  11. Shutdown and restart the Top Secret started task to implement CPF.

  12. Test CPF.

NODE(LU0,A22CCI,01,SYSB,24576,START/STOP)

CONNECT(SYSB)

PERMIT(NONE)

Example System B CCI control Parms

SYSID(SYSB)

PROTOCOL(VTAM,A22CCI,01,SYSB,24576,START/STOP)

NODE(LU0,A24CCI,01,SYSA,24576,START/STOP)

CONNECT(SYSA)

PERMIT(NONE)

Example System A TSS/CPF Parms
CPF(ON)

CPFNODES(SYSB)

CPFRCVUND(NO)

CPFWAIT(NO)

********************************************
Example System B TSS/CPF Parms
CPF(ON)

CPFNODES(SYSA)

CPFRCVUND(NO)

CPFWAIT(NO)
