Chapter 3. Plug-in Implemented Server Functionality Reference176dbcachehitratioThis attribute shows the percentage of requested pages found in the database cache (hits/tries).dbcachepageinThis attribute shows the pages read into the database cache.dbcachepageoutThis attribute shows the pages written from the database cache to the backing file.dbcacheroevictThis attribute shows the clean pages forced from the cache.dbcacherwevictThis attribute shows the dirty pages forced from the cache.3.4.3. Database Attributes under cn=NetscapeRoot, cn=ldbmdatabase, cn=plugins, cn=config and cn=userRoot, cn=ldbmdatabase, cn=plugins, cn=configThe cn=NetscapeRoot and cn=userRoot subtrees contain configuration data for, or thedefinition of, the databases containing the o=NetscapeRoot and o=userRoot suffixes. Thecn=NetscapeRoot subtree contains the configuration data used by the Administration Server forauthentication and all actions that cannot be performed through LDAP (such as start/stop), and thecn=userRoot subtree contains all the configuration data for the user-defined database.The cn=userRoot subtree is called userRoot by default. However, this is not hard-coded and, giventhe fact that there are going to be multiple database instances, this name is changed and defined bythe user as and when new databases are added. The cn=userRoot database referenced can be anyuser database.The following attributes are common to both the cn=NetscapeRoot, cn=ldbm database,cn=plugins, cn=config and the user database, such as cn=userRoot or cn=database_name,cn=ldbm database, cn=plugins, cn=config subtrees.3.4.3.1. nsslapd-cachesizeThis attribute has been deprecated. To resize the entry cache, use nsslapd-cachememsize.This performance tuning-related attribute specifies the cache size in terms of the number of entriesit can hold. However, this attribute is deprecated in favor of the nsslapd-cachememsize attribute,which sets an absolute allocation of RAM for the entry cache size, as described in Section 3.4.3.2,“nsslapd-cachememsize”.Attempting to set a value that is not a number or is too big for a 32-bit signed integer (on 32-bitsystems) returns an LDAP_UNWILLING_TO_PERFORM error message with additional error informationexplaining the problem.The server has to be restarted for changes to this attribute to go into effect.
