DREFLUSHANDPAUSE

Prepares DIH for a snapshot (hot backup). DIH flushes all files to disk and pauses indexing, so a snapshot of the data can be taken. This index action is most applicable if your IDOL storage is a SAN with disk-snapshot capabilities.

Note: The index ID returned from this index action (for example, INDEXID=41) because you need this ID to restart the paused indexing queue.

After sending the index action, poll DIH with the IndexerGetStatus action until the returned status is -16 (Indexing Paused). You can then perform the snapshot.

After the hot backup completes, restart the index queue, again with the IndexerGetStatus action and with the index ID returned from DREFLUSHANDPAUSE. For example:

http://Hume:20000/action=IndexerGetStatus&index=41&IndexAction=restart

Example

http://Hume:20001/DREFLUSHANDPAUSE?

This index action uses port 20001 to instruct the DIH on host Hume to flush all files to disk and pause indexing.

Parameters

IgnoreMaxPendingItems Whether to ignore the IndexQueueMaxPendingItems limit for this index action.
