z/OS
No modifications are needed for IBM z/OS environments. If you are using the extended architecture (XA) option of CICS, the product performs the following activities:
Detects these environments dynamically and exploits them
Automatically places all programs and work areas above the 16-MB line, except for a control program of 266 bytes
Obtains storage from EDSA if you are using CICS/ESA
We recommend the storage that is listed in the following table. These recommendations are based on a z/OS environment (with the XA option of CICS being used) in which all storage that is used by SUPEROPT is obtained from above the 16-MB line. CICS storage is allocated from the EDSA.
