XIV Application Server On z/OS Considerations
* Note that only the SAP Central Services ASCS and SCS
are now supported on Unix System Services under z/OS *
1. The following OSS Notes should be reviewed:
595331 - z/OS enhanced ascii support & FTP updates
1009521 - Central Services does not start
2. Indicate at the time of the sizing that the central services instance will run on S/390
or z/OS, since this will affect the processing and memory requirements.
3. Review BPXPRMxx parameters, TCP/IP setup, and filesystem setup as documented
in the SAP Planning Guide for SAP NetWeaver for IBM DB2 UDB for z/OS and the
ASCS+SCS Installation Guide.
4. Disable SMF Record Type 92 (tracks HFS File activity).
5. Verify that the user exit IEFUSI is not limiting memory allocation for the central
services instance startup.
