Performance Tuning for Content Manager

144 Performance Tuning for Content Manager

6.1 Introduction

Tuning a Content Manager system involves tuning the operating system, DB2,

WebSphere Application Server, and Tivoli Storage Manager. Some of the tuning

and configuration can be done during or immediately after the system

installation. It is very important to include operating system tuning considerations

before the system goes into production. Some other tasks should be performed

during regular maintenance tasks.

Proper performance tuning is more than a solution to a performance problem.

With proper monitoring, performance tuning can be addressed during regular

maintenance schedules, minimizing performance impact on the system users.

6.2 Best practices for system performance

This checklist includes some of the most common applicable performance tuning

recommendations from the Content Manager Performance Team at the Silicon

Valley Lab and services practitioners in the field. The tasks presented here are

the most common suggestions for an initial install. These tasks are not all of the

performance tuning tips available, but they are the most common and considered

the best practice steps. The tasks are covered in detail in their respective chapters

in this book. We do not cover all operating systems and databases specifically.

Keep in mind that many of the principals and methodologies are still applicable.

Figure 6-1 on page 145 shows the performance methodology over the life cycle

of a Content Manager system we followed when designing the best practices

checklist. Even though the assumption is that the best practices are followed

during an initial install and configuration, these best practices can be

implemented at any time.
