Server exit parameter list and processing

z/OS MVS Programming: Sysplex Services Guide
SA23-1400-00

The server exit parameter list is mapped by ixcysrvr_tSXPL as part of the mapping macro IXCYSRVR. A server code within that parameter list identifies the specific type of processing that the server exit is to perform.

The SXPL has a base portion that is common to all server codes, and a variable portion that is unique to each particular server code. The server exit routine will need to process server codes for the following functions:
  • Initializing the server
  • Providing a work area for XCF
  • Processing a request sent by a client

For programming details, see "User routine processing" in Coding a server exit routine.
