This video series explains how to prepare to install Rational Collaboration for Lifecycle Management version 2012.
Topics include: Hardware and Software minimums, Topology Considerations, Jazz Team Servers, and Planning URIs.
Preparation is CRITICAL to CLM installation as many variables, once set, are difficult and impractical to change or modify at a later time.
Your CLM installation will be fast and efficient if you collect the proper information and plan ahead of time.
A 64-bit operating system and a minimum of 4 GB of server memory provide the best environment for running the Jazz™ Team
Server. 32-bit servers are no longer supported. For a complete list of system requirements and sizing guidelines for the
current release see the CLM 2012 InfoCenter. Note that the configuration and administration of your environment is easier when all of the
hardware and software components are of the same type and version. To maximize performance for Rational® CLM applications,
you must understand your own installation environment and how it handles certain factors that can affect its performance.
The following factors can affect performance:
Network latency between all of the physical servers involved should be as small as possible. This is especially true for the
network between the application server and the database server,
for the network between an application and its Jazz™ Team Server (JTS). For the network between servers and network attached
storage (NAS), latency should be as small as possible.
Ensure that the machine specifications match the workload of the installed software. The database server should have fast disk
access and the application server should have a fast CPU. Both servers will work better with more memory.
Also ensure that the application server and database processes are configured to use the available memory.
Ensure that the application server and database software is up to date and tuned using tuning guides for those products.
For example, using DB2 9.7 should provide better performance than DB2 9.5.
Note that WebSphere Application Server can provide performance improvements over the Tomcat Server.
Ensure the OS is tuned using OS specific tuning options. This is also related to the workload of the machine.
Database servers should be tuned to allow fast disk access, while application servers should be tuned for CPU and network
performance. Applications should be tuned, such as reducing the number of viewlets. Viewlet population can affect performance.
If you find that you do not use some of the viewlets on the home page, close them. The viewlets query the server frequently, which can
reduce performance.
Internet browsers affect performance. For example, the Quality Management application works more efficiently on Mozilla Firefox than
on Microsoft Internet Explorer. In Quality Management, you can use the column-filtering capabilities when running queries on
test artifacts; this limit the number of artifacts that display and locates specific test artifacts more quickly, which improves performance.
