Tuning federated LDAP repositories in Liberty
You can improve the performance of the federated LDAP repositories by monitoring and adjusting the cache and the context pool elements in the server.xml file.
About this task
The cached query results of the LDAP repositories save time, because the data need not be retrieved from the back-end server every time an LDAP operation is performed. The LDAP cache attributes are stored in the <ldapCache> element for quicker access. You must monitor the status of the cache and adjust the cache control parameters to improve the performance of the cache. The context pooling parameters can be adjusted to improve the performance of concurrent accesses to the LDAP servers.
