db2perfr - Performance monitor registration tool command

The db2perfr command is used to register an administrator user name and password with Db2® when accessing the performance monitor on Windows operating systems. This allows a remote performance monitor request to correctly identify itself to the Db2 database manager, and be allowed access to the relevant Db2 performance information. You also need to register an administrator user name and password if you want to log counter information into a file using the Performance Logs function.

Usage notes

  • Once a user name and password combination has been registered with the Db2 database system, even local instances of the performance monitor will explicitly log on using that user name and password. This means that if the user name information registered with the Db2 database system does not match, local sessions of the performance monitor will not show Db2 performance information.
  • The user name and password combination must be maintained to match the user name and password values stored in the Windows security database. If the user name or password is changed in the Windows security database, the user name and password combination used for remote performance monitoring must be reset.
  • The default Windows performance monitor user name, SYSTEM, is a reserved word in Db2 database products and cannot be used.
