What are the steps to change the hostname that is put in the CCM WebServer URL list to access Control-M Web Server component, Client Distribution, Self Service, Application Integrator, etc?

By default, the generated url for the Control-M Web Server contains the short hostname of the machine where the web server is running. It may be needed to change this to the fully qualified domain name instead for the client machines to be able to access it.
The Control-M Web Server components is used to display the online Help in the WLA client, for Self Service, Batch Impact Manager and Application Integrator, as well as client deployment. 

- For Version 9.0.18 and higher, use the restore_host_config utility with the -interface_name flag.

9.0.19 :

9.0.20 :

9.0.21 :

This utility makes changes in the CORBA configuration files and a few other files. Changing the web_server_params.xml without running the utility can cause the configuration in the file to be replaced with the original values.

See documentation on: em restore_host_config -interface_name -name <FQDN>
Update web_server_params.xml using the instructions in the documentation.


- For Version 9.0.00 apply the following steps:

   1. On the Control-M EM server machine, edit the file <EM_HOME>\client_updates\conf\web_server_params.xml

   2. Change the hostname in the WEB_SRV_HOST parameter

   <WEB_SRV_HOST>hostname.mycompany.com</WEB_SRV_HOST>

   3. The following line should also be changed:

   <ALLOW_MODIFICATION>true</ALLOW_MODIFICATION>

     change to:

   <ALLOW_MODIFICATION>false</ALLOW_MODIFICATION>

   4. check em database table config_ha, update as needed
  
   5. Then Log into the CCM application, right click the Web server component and choose: Recycle

   Note: If problem is not fixed restarting the Web Server, please restart all Control-M/Enterprise Manager Server components, as it has been found in some cases where problem is resolved only after recycle the whole Control-M/Enterprise Manager.
