Optional. Enables the repository agent caching, which improves the performance when the Integration Service runs multiple sessions repeatedly. If you enable this property, the Repository Service process caches metadata requested by the Integration Service and the metadata that describes repository objects. Default is Yes.

Optional. Number of objects that the cache can contain when repository agent caching is enabled. You can increase the number of objects if there is available memory on the machine where the Repository Service process runs. Default is 10,000.

Optional. Allows you to use PowerCenter Client tools to change metadata in the repository when repository agent caching is enabled. When you enable writes, the Repository Service flushes the cache each time you save metadata through the PowerCenter Client. If you disable writes, you cannot save metadata to the repository through the PowerCenter Client, and the cache is not flushed. When you disable writes, the Integration Service can still write session and workflow metadata to the repository. The Repository Service does not flush the cache when the Integration Service writes metadata. Default is Yes.
