Understanding Connectivity in a Mixed Sysplex Environment z/OS MVS Programming: Sysplex Services Guide SA23-1400-00 |
|
In a mixed sysplex environment made up of systems at MVS™ SP Version
5 and OS/390® Release 1, each
of those systems must have APAR OW19718 installed in order to coexist
with one or more OS/390 Release
2 systems. The APAR allows the systems to use the SFM weights in
a consistent manner. With this support, the system selects a coupling
facility for structure allocation based on the level of the system
invoking the IXLCONN service:
In a mixed sysplex environment in which any system is at the MVS SP Version 4 level, that system will cause a request from another system to connect to a structure with a specification of IXLCONN CONNECTIVITY=SYSPLEX to fail. |
