Configuring ACL cache, entry cache, and filter cache from the command line

Edit online

You can configure the ACL cache, entry cache, and filter cache from the command line. You must tune these caches to improve a directory server performance for search operations.

Procedure

  1. Log in with the directory server instance owner credentials.
  2. To configure LDAP cache configuration variables, run the following command: 
    ldapmodify -p port -D adminDN -w adminPW -i filename
    where, filename contains the following entries: 
    dn: cn=Directory,cn=RDBM Backends,cn=IBM Directory, cn=Schemas,cn=Configuration
changetype: modify
replace: ibm-slapdDbConnections
ibm-slapdDbConnections:15
 
dn: cn=Front End, cn=Configuration
changetype: modify
replace: ibm-slapdACLCache
ibm-slapdACLCache: TRUE
-
replace: ibm-slapdACLCacheSize
ibm-slapdACLCacheSize: 25000
-
replace: ibm-slapdEntryCacheSize
ibm-slapdEntryCacheSize: 25000
-
replace: ibm-slapdFilterCacheSize
ibm-slapdFilterCacheSize: 25000
-
replace: ibm-slapdFilterCacheBypassLimit
ibm-slapdFilterCacheBypassLimit: 100
  3. Restart the directory server and administration server to effect the changes made.
