Optimizing Local LDAP Settings

When the Local LDAP receives excessive requests, the requests are cached. However, if the the cache is overloaded, it causes the LDAP to become unresponsive. From v9.1.0.3, a standard set of values for the cache that is required for optimal handling of the LDAP requests is set in the system. After you upgrade to v9.1.0.3, you can tune the cache parameters for the Local LDAP configuration. The default values for the cache parameters is shown in the following list.

• The slapd.conf file in the /etc/ldap directory contains the following cache values:
  • cachesize 10000 (10,000 entries)
  • idlcachesize 30000 (30,000 entries)
  • dbconfig set_cachesize 0 209715200 0 (200 MB)
• The DB_CONFIG file in the /opt/ldap/db* directory contains the following the cache values:
  • set_cachesize 0 209715200 0 (200 MB)

Based on the setup and the environment in the organization, you can choose to increase the parameters.

Ensure that you back up the files before editing the parameters.

1. On the CLI Manager, navigate to Administration > OS Console.
2. Edit the values for the required parameters.
3. Restart the slapd service using the /etc/init.d/slapd restart command.
