# DRERESIZEINDEXCACHE

Allows you to resize the Content component indexing cache without restarting the server.

The default size of the index cache at Content startup is determined by the value of the IndexCacheMaxSize configuration parameter in the `[IndexCache]` section of the Content configuration file. Using the `DRERESIZEINDEXCACHE` index action allows you to change the cache size dynamically, for example, to decrease it after performing a large bulk indexing job.

NOTE: Because the cache must be flushed before it is resized, invoking this index action more often than necessary might degrade indexing performance.

## Example

    http://12.3.4.56:9101/DRERESIZEINDEXCACHE?IndexCacheMaxSize=20480

This index action sets the index cache size to approximately `20` Mb.

## Required Parameters

The following action parameters are required.

Parameter | Description
--- | ---
IndexCacheMaxSize | The new cache size.

## Optional Parameters

This action accepts the following optional parameters.

Parameter | Description
--- | ---
MaxSyncDelay | The maximum seconds to delay before writing indexed data to disk.

This index action accepts the following standard index action parameters.

Parameter | Description
--- | ---
IgnoreMaxPendingItems | Whether to ignore the IndexQueueMaxPendingItems limit for this index action.
IndexUID | An identification code for any document tracking events.
NoArchive | Turn off configured archiving for the index action.
Priority | The priority for the index job.

## Comments

Using this index action does not change the value of the IndexCacheMaxSize configuration parameter.
