Hardware requirements

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: 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: 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.
