How to Change the System User

You use the System Identity Utility, installed on the Performance Center Server, to change the system user on the Performance Center Server and hosts.

When you change the system user, or a user's password, the System Identity Utility updates the Performance Center Server and hosts.

To learn more about the Performance Center system user, see Performance Center System User.

1. Prerequisites

   • When changing the system user, Performance Center must be down. That is, all users must be logged off the system and no tests may be running.

   • When changing the user password:

   • Ensure that each host is listed in the Machines table under one alias only.

   • In the case of a domain user, when the domain IT team notifies you that the password is to be changed, you need to temporarily change the Performance Center system user on the Performance Center Server and hosts to a different user. After the domain IT team has changed the password of the domain user and has notified you of this change, you need to change the Performance Center system user back to the domain user on the Performance Center Server and hosts.

2. Launch the System Identity Utility on the Performance Center Server

   1. In the Performance Center Server installation's bin directory, open the System Identity Utility (<Performance Center Server Installation directory>/bin/IdentityChangerUtil.exe).

   2. Enter the ALM details to connect to ALM.

   The System Identity Utility opens. For user interface details, see System Identity Utility Window.

3. Change the details of the Performance Center user

   Enter the relevant details to update and click Apply. The utility updates the Performance Center Server and hosts, starting with the Performance Center Server.

   In the lower part of the utility window, the Machines table displays the status of each machine during the configuration process.

   If the utility is unable to change the user on the Performance Center Server, it stops the configuration, rolls back the change, and issues a message explaining why the change cannot be made. Correct the error and click Apply again.

   When configuration completes successfully on the Performance Center Server, the utility proceeds with the configuration of the hosts. The utility attempts to configure all the hosts, even if the configuration on one or more hosts is unsuccessful. In this case, after the utility has attempted to configure all the hosts, correct the errors on the failed hosts, and click Reconfigure. The utility runs again on the whole system.

4. Verify that the system user was changed on the Performance Center Server

   1. Open IIS Manager. Under Sites > Default Web Site, choose a virtual directory.

   2. Under Authentication select Anonymous Authentication. Verify that the anonymous user defined was changed for the following virtual directories: PCS, LoadTest and Files (a virtual directory in LoadTest).

   3. Check in the PCQCWSAppPool and LoadTestAppPool application pools that the identity is the Performance Center user.
