Processors
The basic requirement is for a processor
that supports the prerequisite operating system and has sufficient processor
storage to meet the requirements of z/OS® V1.4, CICS® TS for z/OS, Version 3.1, the application
programs, the access methods, and all other software being run. This includes
the IBM® eServer™ zSeries® 990.
Parallel
Sysplex support
A Parallel Sysplex® environment
is required by each of the data-sharing facilities supported by CICS, and by
the MVS™ system
logger's log stream merging facility. This requires:
- One or more coupling facilities with their associated coupling links installed
- An IBM sysplex
timer to provide a common external time source
- Sufficient DASD paths to support the number of central processor complexes
(CPCs) in the sysplex. The DASD paths can be provided either by DASD controllers
with enough paths to dedicate one to each CPC in the sysplex, or by an ESCON® director.
CICS support for data sharing can be used to access data in IMS™ databases, DB2® databases,
VSAM data sets, CICS temporary
storage, coupling facility data tables, and named counters.
Cryptographic hardware
zSeries cryptographic hardware
is required:
- To exploit the WS-Security capability.
- To fully benefit from the performance improvements to SSL encryption.
Both functions rely upon the z/OS Integrated Cryptographic Services
Facility (ICSF).
Katakana Terminal Devices
Because CICS has to issue
certain messages in mixed-case, the product is not supported with displays
or terminal emulators that are restricted to the non-extended single-byte
character set (SBCS) Katakana part of code page 930.
