Partitions with Enable/Disable


Partitioning an Application

To partition an application, divide up the application components that make up an application. Application components are then hosted by separate NAS machines. Partitioning applications allows the type of processing each NAS machine performs to be specialized.

Parts of the application are hosted on different NAS. Each server knows on which other servers the application component objects of the application are hosted and forwards requests to the appropriate server.

To partition an application, perform the following steps:

  1. Open the Application window of NAS Administrator.
  2. In the left pane of the Application window, double-click the server to be deployed .
  3. Click the group of application components to be deployed.
  4. From the right pane of the Application window, click Deploy Application Group.
  5. Deploy components to at least two NAS machines.
  6. Enable load balancing among servers that the application is partitioned across.
  7. Click Apply Changes for each NAS machine to which changes are made.

Disable the Deployed Application Components

Deploy the components to two or more NAS machines and enable load balancing among the servers that the application is going to be partitioned across. There is an option to disable the deployed application components when deploying the application. Use this option when there are more components to be disabled than enabled. Go back later and enable the components hosted on the new server or servers.

If the application is already hosted on multiple servers, disable the appropriate components on each server to partition the application.

 To set the Enabled/Disabled property from the NAS Administrator:

  1. Open the Application screen of the NAS Administrator tool.
  2. In the left frame, highlight the server to change and the application to modify.
  3. Check to enable each registered server to load balance the application component or application between.
  4. Alternatively, click on the Toggle Enable button for the appropriate mode.
  5. Click OK and then Apply.
  6. Repeat for each Netscape Application Server participating in the load balancing of the application component.
