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 |
| Disk | DS8000 with PAV enabled |
| Operating System | z/OS 1.9 or higher |
| Application server | Tomcat 5.5 or WebSphere Application Server 6.1.0.32 or higher |
| Database | DB2 9.1 |
Application server – System z990 with 1500 mips or higher (dual-tier configuration) | |
|---|---|
| Memory | 6GB or higher |
| Disk | DS8000 with PAV enabled |
| Operating System | z/OS 1.9 or higher |
| Application server | Tomcat 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 |
| Disk | DS8000 with PAV enabled |
| Operating System | z/OS 1.9 or higher |
| Database | DB2 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) | |
|---|---|
| Memory | 16GB or higher |
| Disk | DS8000 with PAV enabled |
| Operating System | z/OS 1.9 or higher |
| Application server | Tomcat 5.5 or WebSphere Application Server 6.1.0.32 or higher |
| Database | DB2 9.1 |
Application server – System z990 with 1500 mips or higher (dual-tier configuration) | |
|---|---|
| Memory | 16GB or higher |
| Disk | DS8000 with PAV enabled |
| Operating System | z/OS 1.9 or higher |
| Application server | Tomcat 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 |
| Disk | DS8000 with PAV enabled |
| Operating System | z/OS 1.9 or higher |
| Database | DB2 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 | |
|---|---|
| Memory | 2GB or higher |
| Disk | DS8000 with PAV enabled |
| Operating System | z/OS 1.9 or higher |
