Installing Natural support

CICS® IA Natural support runs as an exit to the Natural Review Data Collector. The Natural Review Data Collector and the CICS IA Natural support exit must be link-edited into an NSN.

Before you begin

Follow these steps to install Natural Support:

Procedure

  1. Verify that the CICS IA Natural exit is available, using program CIURDCX1 found in the hlq.SCIULOAD library
  2. Follow the instructions for link-editing the Natural Review Data Collector, (NATRDC) into an NSN as provided by the vendor. The exit can be linked into one of three places:
    • The Independent (shared) nucleus NATvvvSH.
    • The CICS dependent nucleus NCvvvRE.
    • A dynamically loaded CICS parameter module.
  3. Link the exit into the CICS dependent nucleus, NCvvvRE:
    1. Specify the RCA , RDCEXIT and RDCSIZE parameters in the Natural/CICS parameter module. These parameters are options on the NTPRM macro. Set the parameters as follows:
      • RCA=(CIURDCX1)
      • RDCSIZE=2
      • RDCEXIT=(CIURDCX1,400)
      Later versions of Natural do not support the use of RDCEXIT as a parameter on the NTPRM macro. Instead you must use the NTRDC macro as shown:
      • NTRDC EXIT=(CIURDCX1,400)
      You can also specify the RDCSIZE using the NTDS macro as shown:
      • NTDS RDCSIZE,2 DATA Collector Buffer
  4. Add the following DD statement for the CICS IA load library to the job used to link-edit the NSN:
    //ACIUMOD DD DISP=SHR,DSN=hlq.ACIUMOD
  5. Add the following linkage-editor control statement to the linkage-editor input stream:
    INCLUDE ACIUMOD(CIURDCX1)
  6. If you are linking into the Independent (shared) nucleus add the following into the job stream:
    //SCIULOAD DD DISP=SHR,DSN=hlq.SCIULOAD          
    
    INCLUDE SCIULOAD(CIURDCX1)

What to do next

When these steps are complete the CICS IA collection of interdependency data will record the names of the Natural programs involved in place of the name of the Natural nucleus.
