Enable Remote Access to DB2 Performance Information

If your DB2 for Windows NT workstation is networked to other Windows NT machines, you can use the feature described in this section.

In order to see Windows NT performance objects from another DB2 for Windows NT machine, you must register an administrator username and password with DB2. (The default Windows NT Performance Monitor username, SYSTEM, is a DB2 reserved word and cannot be used.) To register the name, type:

   db2perfr -r username password

The username and password data is held in a key in the registry, with security that allows access only by administrators and the SYSTEM account. The data is encoded to prevent security concerns about storing an administrator password in the registry.

Notes:

1. Once a username and password combination has been registered with DB2, even local instances of the Performance Monitor will explicitly log on using that username and password. This means that if the username information registered with DB2 does not match, local sessions of the Performance Monitor will not show DB2 performance information.

2. The username and password combination must be maintained to match the username and password values stored in the Windows NT Security database. If the username or password is changed in the Windows NT Security database, the username and password combination used for remote performance monitoring must be reset.

3. To deregister, type:

      db2perfr -u
