When you notice degradation in performance of a Tivoli® Storage
Manager solution,
start by verifying that conditions outside of the server and client
are not the cause. Learn about problem symptoms and causes, and how
to use tools to identify them.
Performance tuning and bottleneck identification
When you tune a Tivoli Storage
Manager solution,
you must look at all of its components and their configuration. Performance
degradation in key operations, including client backups, storage pool
migration, and expiration, can be the result of insufficient resources,
poor configuration, or both.
Taking the first steps for solving performance problems
Start by looking for problems that are indicated by system
errors or obvious deficiencies outside of Tivoli Storage
Manager. After you
are satisfied that no such problems exist, continue by reviewing information
about identifying performance problems in the Tivoli Storage
Manager environment.
Throughout the process, monitor for errors and changes in performance.
Identifying performance bottlenecks
When you suspect that you have a performance problem or
want to improve performance, you can use the provided flowcharts to
help identify sources of performance issues. The charts suggest the
use of tools and scripts to help you measure performance on your system.
Server instrumentation reference
You can use server instrumentation to track operations,
such as backup and restore, and to help identify where performance
problems originate.
