What Does the Status of a Queue Mean?

Status

Purpose

Idle

The queue server collects incoming documents and triggers their preprocessing. Other than this, it is not carrying out any actions at the moment.

Indexing

The queue server transmits documents to the index server and triggers indexing there.

Optimizing

The queue has triggered optimization and is waiting for a response from the index server.

Merging

The queue has triggered the integration of the delta index and is waiting for a response from the index server.

Replicating

The queue has triggered the replication of the index and is waiting for a response from the index server.

Repairing

The queue has errors and is being repaired by the queue server.

This status can occur if you do not stop the queue server in the normal way. This can cause the queue to have an inconsistent state. When you next start the queue server it automatically tries to repair the queue.

To Be Rolled Back

The queue server has designated the queue and index to be rolled back.

A rollback is necessary if the queue and index are inconsistent. This can occur if an error occurred during optimization that caused the index server to terminate the optimization process. The rollback returns the queue and index to their previous, consistent state.

The rollback affects documents that are being indexed or have already been indexed and that have not yet been optimized. These documents receive the status To Be Indexed again, causing TREX to repeat the processing for them.

The queue server automatically triggers the rollback at the next possible point in time.

Rolling Back

The rollback is currently running.

<activity> Suspend in Progress

You have tried to suspend the queue. The queue server is completing the current activity. The queue will stop when the activity has been completed.

Roll Back Suspended

You have suspended the rollback.

Suspended

You have suspended the queue.
