Edit Server Configurations Using the CGE UI

Procedure and guidelines for modifying the CGE server's configuration settings using the CGE front end.

The Edit Server Configuration interface allows editing server configurations.
CAUTION: Modifying server configuration settings can adversely affect performance, especially if it is changed to point to a relatively slow file system. Therefore, it is recommended not to change server configuration settings, unless specifically instructed to do so by a Cray representative in order to gather information for diagnosing issues.
  1. Optional: Log on to the CGE UI by pointing a browser at http://machine-login1:3756/login, entering credentials and then selecting the Login button.
    This step is optional, depending on how the interface has been configured
  2. Access the CGE Edit Server Configuration interface, by using one of the following mechanisms:
    • Point a browser at http://machine:3756/dataset/config, where machine is the machine running CGE’s web server.
    • Select Edit Database Configuration from the Configuration Management drop down on the CGE UI.

  3. Select the desired server NVP and logging options using the Server NVPs and Server Logging Options sections of the UI. In addition to the Server NVPs and Server Logging Options, this interface also contains a Server Output Directory field that allows changing the server output directory. This is the directory to which the database writes results, and from which the web server reads in order to deliver query results over HTTP.
  4. Select the Reconfigure Server button when the changes have been made.
    Unlike the options presented in the other interfaces, the values set from this interface persist for the lifetime of the server and become the new defaults.
    Upon doing so, the system will return a response detailing the success/failures of the pieces of configuration that were to be updated, as shown in the following example output:
    Updated Server NVP Configuration successfully
Updated Server Logging Configuration successfully
