Rational Team Concert 3.0 sizing guide for z/OS

This article provides sizing recommendations specifically for z/OS. Read the Rational Team Concert 3.0 sizing guide first for basic Rational Team Concert sizing recommendations.

Small-scale enterprise deployment

For this sizing guide, a small-scale deployment is a configuration of between 100 and 700 users on either a single-tier or a double-tier setup. For a single-tier setup, the application server and database are running on the same LPAR. For dual-tier setup, the application server and database are running on different LPARs.

The following tables list the system recommendations for small-scale setup scenarios:

Application server and database – System z990 with 1800 mips or higher (single-tier configuration)
Memory 6GB or higher
DiskDS8000 with PAV enabled
Operating System z/OS 1.9 or higher
Application serverTomcat 5.5 or WebSphere Application Server 6.1.0.32 or higher
DatabaseDB2 9.1
Application server – System z990 with 1500 mips or higher (dual-tier configuration)
Memory 6GB or higher
DiskDS8000 with PAV enabled
Operating System z/OS 1.9 or higher
Application serverTomcat 5.5 or WebSphere Application Server 6.1.0.32 or higher
Database – System z990 with 300 mips or higher (dual-tier configuration)
Memory 6GB or higher
DiskDS8000 with PAV enabled
Operating System z/OS 1.9 or higher
DatabaseDB2 9.1

Large-scale enterprise deployment

For this sizing guide, a large-scale deployment is a configuration of between 700 and 2000 users on either a single-tier or a double-tier setup. For a single-tier setup, the application server and database are running on the same LPAR. For dual-tier setup, the application server and database are running on different LPARs.

The following tables list the system recommendations for large-scale setup scenarios:

Application server and database – System z990 with 4000 mips or higher (single-tier configuration)
Memory16GB or higher
DiskDS8000 with PAV enabled
Operating System z/OS 1.9 or higher
Application serverTomcat 5.5 or WebSphere Application Server 6.1.0.32 or higher
DatabaseDB2 9.1
Application server – System z990 with 1500 mips or higher (dual-tier configuration)
Memory 16GB or higher
DiskDS8000 with PAV enabled
Operating System z/OS 1.9 or higher
Application serverTomcat 5.5 or WebSphere Application Server 6.1.0.32 or higher
Database – System z990 with 300 mips or higher (dual-tier configuration)
Memory 6GB or higher
DiskDS8000 with PAV enabled
Operating System z/OS 1.9 or higher
DatabaseDB2 9.1

Rational Build Agent

The Rational Build Agent is required for System z builds. For additional information, see Working with Enterprise Extensions builds.

The following table lists the system recommendations for the Rational Build Agent:

System z990 with 100 mips or higher
Memory2GB or higher
DiskDS8000 with PAV enabled
Operating System z/OS 1.9 or higher
