Issue the iKeycmd command to add the cert256.arm certificate as the default certificate in the key database file of the hub server:

# /opt/tivoli/tsm/ui/jre/bin/ikeycmd -cert -add -db /opt/tivoli/tsm/ui/Liberty/usr/servers/guiServer/gui-truststore.jks -file /fvt/comfrey/srv/cert256.arm -label 'label description' -pw 'password' -type jks -format ascii -trust enable

To restart the initial configuration wizard, you must delete a properties file. When you delete the file, you delete information about the hub server connection. However, any alerting, monitoring, at-risk, or multiserver settings that were configured for the hub server are not deleted. These settings are used as the default settings in the configuration wizard when the wizard restarts.

1. Stop the web server of the Operations Center. For instructions, see Stopping and starting the web server.

2. On the computer where the Operations Center is installed, go to the following directory:

      AIX® and Linux systems: installation_dir/ui/Liberty/usr/servers/guiServer
      Windows systems: installation_dir\ui\Liberty\usr\servers\guiServer
  where installation_dir represents the directory in which the Operations Center is installed. For example:
      AIX and Linux systems: /opt/tivoli/tsm/ui/Liberty/usr/servers/guiServer
      Windows systems: c:\Program Files\Tivoli\TSM\ui\Liberty\usr\servers\guiServer
      

3. In the guiServer directory, delete the serverConnection.properties file.

4. Start the web server of the Operations Center.

5. Open the Operations Center. Start a web browser, and enter the following address: https://hostname:11080/oc, where hostname represents the name of the computer where the Operations Center is installed, and secure_port represents the port number that the Operations Center uses for HTTPS communication on that computer.

6. Use the configuration wizard to reconfigure the Operations Center. Specify a new password for the monitoring administrator ID.

7. Update the password for the monitoring administrator ID on any spoke servers that were previously connected to the hub server. Issue the following command from the Tivoli® Storage Manager command-line interface:

  UPDATE ADMIN  IBM-OC-hub_server_name new_password
  

If you want to update you configuration, access the configuration interface
