Follow this page to manage the realm in a federated repository
configuration.
Before you begin
The settings that are available on the Performance panel are
independent options that pertain specifically to the federated repositories
functionality. These options do not affect your entire WebSphere Application
Server configuration.
Procedure
- In the administrative console, click Security > Secure
administration, applications, and infrastructure.
- Under User account repository, select Federated repositories from
the Available realm definitions field and click Configure.
- Under Related items, click Manage repositories > repository_name.
- Under Additional properties, click Performance.
- Optional: Select the Limit search time option
and enter the maximum number of milliseconds that the Application
Server can use to search through your Lightweight Directory Access
Protocol (LDAP) entries.
- Optional: Select the Limit search returns option
and enter the maximum number of entries to return that match the search
criteria.
- Optional: Select the Use connection pooling option
to specify whether the Application Server can store separate connections
to the LDAP server for reuse.
- Optional: Select the Enable context pool option
to specify whether multiple applications can use the same connection
to the LDAP server. If you select the option, specify the initial,
preferred, and maximum number of entries that can use the same connection.
The Enable context pool option can be enabled either
in conjunction with the Use connection pool option or separately.
If this option is disabled, a new connection is created for each context.
You can also select the Context pool times out option and specify
the number of seconds after which the entries in the context pool
expire.
- Optional: Set the Maximum size value
of the context pool to zero (0).
- Optional: Select the Cache the attributes option
and specify the maximum number of search attribute entries. This
option enables WebSphere Application Server to save the LDAP entries
so that it can search the entries locally rather than making multiple
calls to the LDAP server. Click the Cache times out option
that is associated with the Cache the attributes option to
specify the maximum number of seconds that the Application Server
can save these entries.
- Optional: Select the Cache the search results option
and specify the maximum number of search result entries. This
option enables WebSphere Application Server to save the results of
a search inquiry instead of making multiple calls to the LDAP server
to search and retrieve the results of that search. Click the Cache
times out option that is associated with the Cache the search
results option to specify the maximum number of seconds that the
Application Server can save the results.
- Optional: Create the root DataObject object
locally using the com.ibm.websphere.wim.util.SDOHelper.createRootDataObject method instead of the com.ibm.websphere.wim.ServiceProvider.createRootDataObject
method.
Results
These options are available to potentially increase the performance
of your federated repositories configuration. However, the any increase
in performance is dependant upon your specific configuration.
