Sun Java System Directory Server Enterprise Edition 6.1 Reference

Import Cache

The import cache is created and used when a suffix is initialized. If the deployment involves offline suffix initialization only, import cache and database cache are not used together. In this case, the import cache and database cache do not need to be added together when the cache size is aggregated. See Total Aggregate Cache Size. When the import cache size is changed, the change takes effect the next time the suffix is reset and initialized. The import cache is allocated for the initialization, then released after the initialization.

Directory Server handles import cache in the same way as it handles database cache. Sufficient physical memory must be available to prevent swapping. The benefits of having a larger import cache diminish for cache sizes larger than 1 GB.
