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

The default size of the index cache at startup is determined by the value of the IndexCacheMaxSize configuration parameter in the [IndexCache] section of the Distributed Index Handler 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.


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


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.  


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