Taking the first steps for solving performance problems

Start by looking for problems that are indicated by system errors or obvious deficiencies outside of IBM Spectrum Protect. After you are satisfied that no such problems exist, continue by reviewing information about identifying performance problems in the IBM Spectrum Protect environment. Throughout the process, monitor for errors and changes in performance.

1. Review the best practices that are described in Configuration best practices. Make changes as needed, based on the information.
2. 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.
   1. 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.
   2. Verify that attached storage devices such as disk systems are operational and have no errors.
   3. Verify that storage and local area networks do not have frequent port errors.
3. Review the server activity log and client error logs.
4. Review the log for the server database, the db2diag.log file. To find the file, see Locating DB2® diagnostic log files.
