# DRERESIZEINDEXCACHE

Allows you to resize the IDOL Server indexing cache without restarting the server.

The default size of the index cache at IDOL Server startup is determined by the value of the IndexCacheMaxSize configuration parameter in the `[IndexCache]` section of the IDOL Server 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://12.3.4.56:20001/DRERESIZEINDEXCACHE?IndexCacheMaxSize=20480

This index action uses port `20001` to set the index cache size to approximately `20` Mb.

## Parameters

Parameter | Description | Required
--- | --- | ---
IgnoreMaxPendingItems | Whether to ignore the IndexQueueMaxPendingItems limit for this index action. |
IndexCacheMaxSize | The new cache size. | Yes
IndexUID | An identification code for any document tracking events. |
MaxSyncDelay | The maximum seconds to delay before writing indexed data to disk. |
Priority | The priority for the index job. |

## Comments

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