High Bandwidth Shared File System Files

High Bandwidth Shared File System Files

Because they can be accessed often during a session, place the following files on a high-bandwidth shared file system:
  • Source files, including flat files for lookups.
  • Target files, including merge files for partitioned sessions.
  • Persistent cache files for lookup or incremental aggregation.
  • Non-persistent cache files for
    only
    grid-enabled sessions on a grid.
    This allows the Integration Service to build the cache only once. If these cache files are stored on a local file system, the Integration Service builds a cache for each partition group.
