IBM CICS Transaction Server, Version 3.1 at a glance
Hardware requirements
• Processor: One that supports the prerequisite operating system and has sufficient processor storage to meet the requirements of the
operating system, CICS Transaction Server, Version 3.1, the application programs, the access methods and all other software being run.
• Parallel Sysplex support: A Parallel Sysplex environment is required by each of the data-sharing facilities supported by CICS, and by the
IBM MVS
™
system logger’s log-stream merging facility. This requires one or more coupling facilities with the associated coupling links
installed, a sysplex timer to provide a common, external time source and sufficient direct access storage device (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 IBM ESCON
®
director to provide the paths.
• Data sharing support: CICS support for data sharing can be used to access data in IBM IMS
™
databases, IBM DB2
®
databases,
virtual storage access method (VSAM) data sets, CICS temporary storage, coupling facility data tables or named counters.
• WS-Security capability: To exploit the WS-Security capability, which relies on the z/OS Integrated Cryptographic Services Facility (ICSF),
appropriate IBM ^
®
zSeries
®
cryptographic hardware is required.
Software requirements
• Operating environment: IBM z/OS, Version 1.4
• The Language Environment library SCEERUN required for CICS Transaction Server initialization, by inclusion in either the STEPLIB
concatenation or the LNKLIST
• IBM Software Developer Kit (SDK) for z/OS, Java 2 Platform, Technology Edition, featuring persistent reusable Java Virtual Machine (JVM)
technology, Version 1.4.2, for Java application programs or enterprise beans
• IBM XML Toolkit for z/OS, Version 1.7 required for WS-Security support (available at no charge)
• IBM WebSphere
®
Application Server, Version 5.0 required to deploy enterprise beans
