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
- Verify that the CICS IA
Natural exit is available, using program CIURDCX1 found in the hlq.SCIULOAD
library
- 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.
- Link the exit into the CICS dependent
nucleus, NCvvvRE:
- 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
- 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
- Add the following linkage-editor control statement to the
linkage-editor input stream:
INCLUDE ACIUMOD(CIURDCX1)
- 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.
