See Chapter 4, "Populating Directory Databases."
Restart your Directory Server.
6.
After you increase your All IDs Threshold value, examine your database cache
size.
Increasing your All IDs Threshold can result in larger memory requirements
caused by larger entry ID lists. The increased in memory requirements will differ
depending on the number and types of indexes that you are maintaining, but the
requirements will never be larger than the factor by which you increased the

your database cache size to more than double its current value.
Increasing your database cache size by the same factor as you increased the All IDs
Threshold is an extreme measure. If you have the physical memory available, try
increasing your database cache size by a factor that is 25 percent of your
nsslapd-allidsthreshold
IDs Threshold value, increase your database cache size by 50 percent. If necessary,
slowly increase your cache size until you are satisfied with your server's
performance.
