Customizing the CICS® IA
Natural Interface includes two tasks: Modifying the Exclusive Work
Area (EWA) size and the Natural Name List size.
Modifying the Exclusive Work Area (EWA) size
The
default size of the EWA allows you to collect information for up to
12 Natural programs for each Natural session. You can change the EWA
size by modifying the RDCEXIT Natural profile parameter for the CICS IA Natural support exit. If
you increase the EWA by 8 bytes you can collect information for one
more Natural program.
Modifying the Natural Name List size
The CICS IA Natural support exit extracts
the Natural information and saves it in an area called the Natural
Name List (NNL). The default size of the NNL allows you to collect
information on up to
252 simultaneous Natural sessions.
To
modify the size of the NNL area:
- Update the supplied source member hlq.SCIUSRCE(CIUNNLP). Follow
the instructions in the source.
* NSESS specifies the maximum number of simultaneous Natural
* sessions. The number must be a value between 2 and 32256.
* A value 252 is the installation default setting.

:- Modify the Job card to meet your site standards.
- Review the ASM.SYSIN card to make sure you are picking up the
modified source.
- Review the LKED.SYSLMOD card to make sure you are linking the
module into the required dataset.
- To make the modified NNL table available to the IA Natural Collector,
ensure that the dataset into which you have linked the modified NNL
module is before the CICS IA
load library in the DFHRPL.
