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 use more resources during deployment.

• Runtime routines for encryption and decryption now use a temporary buffer that is a max size of 16.7MB. This large buffer is released as soon as the algorithm has completed processing the buffer.
• Runtime user exit TIRSIPEX (CICS Sockets Server Exit) need modifications to the timeout parameters SELECT-TIMEOUT-SECS and SELECT-TIMEOUT-MICROSEC. These parameters are evaluated and increased as appropriate.
• The default MQSeries message length is evaluated and increased as appropriate.
