Configuring a Numeric Cache Size

Configuring a Numeric Cache Size

You can configure a specific value for the cache size. You configure a specific value when you tune a cache size. The first time you configure the cache size, you can use the cache calculator or auto cache memory. After you configure the cache size and run the session, you can analyze the transformation statistics in the session log to tune the cache size. The session log shows the cache size required to process the transformation in memory without paging to disk. Use the cache size specified in the session log for optimal session performance.
