Directory Server allows you to change the configuration of the following while the server is running:
Suffixes. After Directory Server has been installed and brought online, you can continue to add new suffixes dynamically while the server keeps running.
Indexes. After you have defined the suffixes, you can add new indexes to accelerate search performance. You can customize your index according to function, such as indexes that list entries that have a particular attribute, that approximate a particular attribute, that contain a substring, or that match a particular locale. Indexes can be updated dynamically without interrupting the normal functions of the directory server itself.
Schema.You can change the directory schema dynamically. If the schema needs to be extended to meet the needs of an application, you can add new object classes and attributes while the server is running, without affecting operations.
Replication topology. You can set up and modify the replication topology while the server is running.
