JES3 in a Parallel Sysplex

This redbook discusses the role of JES3 in a Parallel Sysplex. It
focuses on those features of MVS/ESA and OS/390 that can be used by JES3
in a Parallel Sysplex, and provides information about the following
topics:JES3 CTC support has been removed from the JES3 code and is
replaced with XCF signaling services and JESXCF. JES3 console services
and JES3-only consoles have been removed with JES3 5.2.1 and are
replaced with MCS multisystem console support. The JES3 MLOG is removed
and can be replaced with either the MVS system logger or a new JES3
DLOG.

The following new MVS sysplex functions supported by JES3 in the
sysplex environment are discussed:Automatic Restart Management, Shared
tape support and JES3 tape management, and system symbolics.

S/390 hardware and software running as a Parallel Sysplex offers a
unique continuous availability platform, handling both fault tolerance
and system management issues. The following issues are discussed in the
context of continuous availability planning:DFSMS and dynamic I/O
reconfiguration, and the advantages of JES3 main device scheduling.

Migration issues that need to be addressed when converting to the
sysplex environment are described. This redbook was written for systems
programmers and IBM personnel involved in implementing a JES3 Parallel
Sysplex.
