Changing Queue AssignmentsLocate this document in the navigation structure

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.

    Note

    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.
