Hi
I am trying to tune the performance of the Directory Server. We have
increased the memory for the database cache and for each database
entry cache. These are the new values:
cn=config, cn=ldbm database, cn=plugins, cn=config
nsslapd-dbcachesize: 838860800 (~800MB)
cn=*,cn=ldbm database, cn=plugins, cn=config
nsslapd-cachememsize: 125829120 (~120MB)
We have 27 databases, and the servers have 16 GB of RAM, so the server
should be able to handle all that memory (800 + 120*27 = 4040MB). But
when I go to the monitoring section of the management console, the
database cache says the hit ratio is 99% (this is OK according to the
documentation, near 100%), but the entry cache is 0%, that is very far
for 100% that the documentation recomends (see screenshots attached).
Am I confused or the configuration is not correct?
When you start out with an empty
cache, the cache hit ratio will be 0
until entries get into the cache and are pulled from the cache rather
than the database.
Try doing a search like ldapsearch ... -b "basesuffixofdatabase"
"objectclass=*"
