Determining WebSphere Application Server for z/OS system requirements

The following sections describe system requirements for WebSphere Application Server for z/OS.

Hardware requirements

[5.0 only][Version 5.0.1][Version 5.0.2]The hardware requirements for this product are any hardware that supports OS/390 Version 2 Release 10 or any version of z/OS Version 1.1 or later. However, there are significant performance advantages for those applications doing floating point arithmetic if the machine has binary floating point hardware, such as S/390 Parallel Enterprise Server-Generation 5 and later systems.

The LPAR in which the WebSphere Application Server for z/OS runtime and initial Application Servers run requires a minimum of 512 MB of real storage. You may need to increase the real storage size depending on the size and number of Application Servers you deploy. In addition, you may want to increase your JES spool space if you use WebSphere Application Server for z/OS tracing options to the SYSPRINT DD dataset.

You should plan on an extra 3390-3 volume for the distribution and configuration HFS data sets, two additional 3390-3 volumes for the WebSphere product code, and two further 3390-3 volumes if you will use the Integrated JMS Provider.

Recommendation: Increase your paging subsystem by one 3390-3 volume if your storage is constrained.

Software requirements

You must install, enable, and configure the following z/OS or OS/390 elements, features, and components. Consult the Program Directory and PSP bucket for the required corrective service.

All of the z/OS sources referenced are available at this Web site: http://www.ibm.com/servers/eserver/zseries/zos/bkserv/

Regarding optional functions, consult the following table:


Software requirements for optional functions
If you plan to use . . . Then you need . . . Notes . . .
Kerberos security OS/390 SecureWay Security Server Network Authentication and Privacy Service for OS/390 For OS/390 and z/OS, this support is part of SecureWay Security Server.
Cryptography Cryptographic Services System SSL, a component of Cryptographic Services Base, an element of z/OS. For details, see z/OS System Secure Sockets Layer Programming.
EJB roles to secure Web components or enterprise beans z/OS Version 1.2 Security Server (RACF) or equivalent For releases of z/OS earlier than z/OS Version 1.2, install the appropriate APAR for this support.
Java Message Service (JMS)
  • Integrated JMS provider
  • Either of the following:
    • MQ stack from WebSphere Application Server for z/OS
    • Full function MQ using MQ 5.3.1
MQSI, a pub sub product that supports z/OS, does not support new function like MDBs.
WebSphere Application Server for z/OS IMS Connect Version 8 support IMS/TM 6.1.0  
WebSphere Application Server for z/OS CICS Transaction Gateway 5.0.1 support CICS/TS 1.3  
DB2 DB2 Version 7.1 DB2 is no longer a prerequisite for WebSphere Application Server for z/OS, though some functions may still require it. For example, session persistence requires an existing database. Check your individual configuration.
DB2 SQLJ in J2EE application components DB2 Version 7.1 PTF UQ59527 DB2 is no longer a prerequisite for WebSphere Application Server for z/OS, though some functions may still require it. For example, session persistence requires an existing database. Check your individual configuration.
Logging z/OS system logger For details, see z/OS MVS Setting Up a Sysplex.
Connectors WebSphere Application Server for z/OS supports any resource adapter that is designed to use the 1.0 level of the J2EE Connector Architecture (JCA). Install the listed IBM connectors if you want to access your IMS or CICS legacy data. For details on how to define and install a specific connector, see the documentation for that particular connector product.
  For the CICS Transaction Gateway ECI connector:
  • CICS Transaction Gateway Version 5.0.1
  • CICS Transaction Server Version 1.3
  • WebSphere Studio Application Developer IE Version 5.0
 
  For the IMS Connector for Java:
  • IMS Connect for z/OS Version 2.1
  • IMS Version 8
  • WebSphere Studio Application Developer IE Version 5.0.1
 
  For the IMS JDBC Connector:
  • IMS Version 8
