Changing Queue Assignments 

Use

When you create an index, TREX automatically creates a corresponding queue and assigns the queue to a master queue server. If you are using backup queue servers, TREX also assigns a backup queue server to the queue.

You can change these assignments if necessary. You may want to do this if you need to remove a host from the distributed system and assign the queues to other servers first.

Prerequisites

You are using centralized data storage.

Procedure

...

       1.      Go to the Queue Landscape window.

       2.      In the table select the queue whose assignment you want to change.

       3.      Click in a column relating to a host. Choose the required function from the context menu.

Function	Description
Move master here	Assigns another master queue server to the queue.
Switch master/backup	Switches the master and backup queue servers. The master queue server is then used as the backup queue server for this queue (and vice versa).
Remove this backup	Removes the assignment of queue to backup queue server.
Add backup here	Assigns another backup queue server to the queue.

The functions only change the assignment of queue to server. The queues are not physically moved.

You can also change the assignments if the currently assigned master or backup queue server is active at that point in time. The currently assigned master or backup server completes its current activity before the change takes effect.
