Cache Directory Location

Cache Directory Location

If you run the Integration Service on a grid and only some Integration Service nodes have fast access to the shared cache file directory, configure each session with a large cache to run on the nodes with fast access to the directory. To configure a session to run on a node with fast access to the directory, complete the following steps:
  1. Create a PowerCenter resource.
  2. Make the resource available to the nodes with fast access to the directory.
  3. Assign the resource to the session.
If all Integration Service processes in a grid have slow access to the cache files, set up a separate, local cache file directory for each Integration Service process. An Integration Service process may have faster access to the cache files if it runs on the same machine that contains the cache directory.
You may encounter performance degradation when you cache large quantities of data on a mapped or mounted drive.
