Special Considerations for large Common Format Buffers

For CA Gen Release 8.5, the amount of customer data that can be sent between CA Gen Client and Servers using Common Format Buffer (CFB) based cooperative flows has increased. The previous CFB limit was 32K. The new limit is 16.7 MB.

Installing the modules larger than 32K require modifications for resources that are used during Compile and Link.

• Internal libraries that are used for source code, listing, ncal loadmodules, executable load modules are increased in size. You are responsible for monitoring the space utilization of the data sets using the ISPF utility. If system generation terminates abnormally with a D37 or B37 system abend, it is likely that the data sets ran out of space or directory blocks.
• Temporary work space that is allocated by parameters TICASUTP and TICASUTS need to be evaluated and appropriately increased. These parameters can be found in the PARMLIB member TIUHE for the Host Encyclopedia and member TIUIT for the z/OS IT and can be modified as necessary.
