LDAP performance settings
Use this page to minimize impacts to performance by adding opened connections and contexts to internally maintained pools and reusing them. Also minimize performance impacts by maintaining internal caches of retrieved data.

- In the console, click...
Security | Global security
- Under User account repository, select Federated repositories from the Available realm definitions field and click Configure. To configure for a specific domain in a multiple security domain environment, click Security domains > domain_name. Under Security Attributes, expand User Realm, and click Customize for this domain. Select the Realm type as Federated repositories and then click Configure.
- Under Related items, click Manage repositories.
- Click Add to specify a new external repository or select an external repository that is preconfigured.
- Under Additional properties, click Performance.

Limit search time
Timeout value in milliseconds for a LDAP server to respond before stopping a request.
Data type: Integer Units: Milliseconds Default: 0 Range: Equal to or greater than 0. A value of 0 specifies that no search time limit exists.
Limit search returns
Maximum number of entries that are returned in a search result.
Data type: Integer Units: Entries Default: 0 Range: Equal to or greater than 0. A value of 0 specifies that no search return limit exists.
Use connection pooling
Whether to utilize the connection pooling function, which is provided in the SDK.
Connection pooling is maintained by the Java run time. It is configured by system properties.
Default: Disabled Range: Enabled or Disabled
Enable context pool
Whether context pooling is enabled to the LDAP server.
To improve performance, use the context pool in combination with connection pooling.
Default: Enabled Range: Enabled or Disabled
Initial size
Number of context instances in the pool when the pool is initially created by the LDAP repository.
Data type: Integer Default: 1 Range: 1 to 50
Preferred size
Preferred number of context instances that the context pool maintains. Both in-use and idle context instances contribute to this number.
Data type: Integer Default: 3 Range: 0 to 100
Maximum size
Maximum number of context instances that can be maintained concurrently by the context pool. Both in-use and idle context instances contribute to this number.
When the pool size reaches the maximum size, no new context instances can be created for a new request. The new request is blocked until a context instance is released or removed. The request periodically checks for context instances that are available in the pool. A request for a pooled context instance uses an existing pooled and idle context instance or a newly created pooled context instance.
A maximum pool size of 0 indicates that the context pool can maintain an infinite number of context instances.
Data type: Integer Default: 0
Context pool times out
Number of seconds for the context pool to time out and remove idle context instances.
A timeout value of 0 indicates that the context pool does not time out context instances.
Data type: Integer Default: 0
Cache the attributes
Whether to cache the attributes that are returned from the LDAP server.
Default: Enabled Range: Enabled or Disabled
Cache size
Maximum size of the cache.
Data type: Integer Default: 4000 Range: Equal to or greater than 100
Cache times out
Maximum number of seconds that the cached search results can stay in the cache.
A timeout value of 0 indicates that the cached search results stay in the cache until update operations are made.
Data type: Integer Units: Seconds Default: 1200 Range: Equal to or greater than 0
Distribution policy
Distribution policy for the cache in a clustered environment, which is one of the following:
Not shared
Sends out new entries, both ID and data, and updates to those entries.
Push
Requests data from other servers in the cluster when that data is not locally present.
Push and pull
Sends out IDs for new entries and requests from other servers in the cluster entries for IDs that were previously broadcast. The dynamic cache always sends out cache entry invalidations.
Cache the search results
Whether to cache the search results that are returned from the LDAP server.
Default: Enabled Range: Enabled or Disabled
Cache size
Maximum size of the cache.
Data type: Integer Default: 2000 Range: Equal to or greater than 100
Cache times out
Maximum number of seconds that the cached search results can stay in the cache.
A timeout value of 0 indicates that the cached search results stay in the cache until update operations are made.
Data type: Integer Units: Seconds Default: 600 Range: Equal to or greater than 0
Distribution policy
Distribution policy for the cache in a clustered environment, which is one of the following:
Not shared
Sends out new entries, both ID and data, and updates to those entries.
Push
Requests data from other servers in the cluster when that data is not locally present.
Push and pull
Sends out IDs for new entries and requests from other servers in the cluster entries for IDs that were previously broadcast. The dynamic cache always sends out cache entry invalidations.
