How Searches Use Cache
112 Sun ONE Directory Server Installation and Tuning Guide • June 2003
Ifall suffix initializationtakesplaceofflinewith Directory Serverstopped,youmay
be able to work around this limitation. In this case import cache does not coexist
with database cache, so you may allocate the same memory to import cache for
offline suffix initialization and to database cache for online use. If you opt to
implement this special case, however, ensure that no one performs online bulk
loads on the production system. The sum of the caches used simultaneously must
still remain smaller than the total size of available physical memory.
How Searches Use Cache
Figure 6-2 illustrates how Directory Server handles both searches specifying a base
DN and searches using filters. Individual lines represent threads accessing
different levels of memory, with broken lines representing steps to minimize
through effective tuning.
