creates at least one cache file for each Aggregator, Joiner, Lookup, Rank, and Sorter transformation. If
Data Integration
cannot run a transformation in memory, it writes the overflow data to the cache files.
For Aggregator, Joiner, Lookup, and Rank transformations,
Data Integration
creates index and data cache files to run the transformation. For Sorter transformations,
Data Integration
creates one sorter cache file. By default,
Data Integration
stores cache files in the directory entered in the Secure Agent $PMCacheDir property for the Data Integration Server. You can change the cache directory on the
Advanced
tab of the transformation properties. If you change the cache directory, verify that the directory exists and contains enough disk space for the cache files.
