Description

 

 

 

increases, and directory search performance

 

drops. To improve this ratio, increase the

 

number of entries that the directory maintains

 

in the entry cache by increasing the value of

 

the Maximum Entries in Cache attribute.

 

See Section 2, “Tuning Database

 

Performance” for information on changing this

 

value using the Directory Server Console.

 

 

currententrycachesize

The total size of directory entries currently

 

present in the entry cache.

 

 

maxentrycachesize

The maximum number of directory entries that

 

can be maintained in the entry cache. This

 

value is managed by the Maximum Entries

 

in Cache setting. See Section 2, “Tuning

 

Database Performance” for information on

 

changing this value using the Directory Server

 

Console.

 

 

dbchehits

The number of times the server could process

 

a request by obtaining data from the cache

 

rather than by going to the disk.

 

 

dbcachetries

The total number of requests performed on

 

the directory since server startup.

 

 

dbcachehitratio

The ratio of cache tries to successful cache

 

hits. The closer this number is to 100%, the

 

better.

 

 

dbcachepagein

The number of pages read from disk into the

 

cache.

 

 

dbcachepageout

The number of pages written from the cache

 

back to disk.

 

 

dbcacheroevict

The number of read-only pages discarded

 

from the cache to make room for new pages.

 

Pages discarded from the cache have to be

 

written to disk, possibly affecting server

 

performance. The lower the number of page

 

evicts the better.

 

 

dbcacherwevict

The number of read-write pages discarded

 

from the cache to make room for new pages.

 

This value differs from Pages Written Out in

 

that these are discarded read-write pages that

 

have not been modified. Pages discarded

 

from the cache have to be written to disk,

 

possibly affecting server performance. The
