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.
Procedure
- Review the best practices that are described in Configuration best practices. Make changes as needed, based
on the information.
- Verify that there are no problems or errors outside of
the server software. Problems in the server hardware, the operating
system, the network, and attached storage devices can severely affect
operations. Fix all errors outside of the server software before you
diagnose server performance issues.
- Review error logs for the operating system to find errors
that can affect the server. For example, for AIX® systems use the errpt command
to view errors. For Linux systems,
look in the /var/log path.
- Verify that attached storage devices such as disk systems
are operational and have no errors.
- Verify that storage and local area networks do not have
frequent port errors.
- Review the server activity log and client error logs.
- Review the log for the server database, the db2diag.log file. To find the file, see Locating DB2® diagnostic log files.
What to do next
Implement modifications and fix any problems as described
in the preceding steps, and then determine whether you must further
analyze performance. Use techniques that are described in
Identifying performance bottlenecks to analyze your system for performance
bottlenecks.
