Indexes

Indexes are used by eDirectoryTM to significantly improve query performance. eDirectory ships with a set of index definitions that provide basic query functionality. You can create customized indexes to further improve eDirectory performance in your environment.

Indexes
Lists all available indexes and index properties in a table.

Index Name
Indexes that are created automatically are given the name of the attribute that is being indexed. User-defined indexes are named by their creator.

Index State

Online
Currently running; can be suspended by clicking Take Offline.

Offline
Suspended; can be started again by clicking Bring Online.

New
Waiting to move to Online.

Deleted
Waiting to be removed from the index table.

Index Type

User
This type is user-defined and is the only type that can be added using Index Manager. This type can be edited and deleted.

Auto Added
eDirectory automatically adds these types during attribute creation. This type can be edited and deleted.

Operational
This type must be present to run the system. It cannot be edited or deleted.

System
This type must be present to run the system. It cannot be edited or deleted.

Index Rule

Value
Matches the entire value or the first part of the value of an attribute. For example, value matching could be used to find entries with a "LastName" that is equal to "Jensen," and entries with a "LastName" that begins with "Jen."

Presence
Requires only the presence of an attribute rather than specific attribute values. A query to find all entries with a "Login Script" attribute would use a presence index.

Substring
Matches a subset of the attribute value string. For example, a query to find a "LastName" with "der" would return matches for "Derington," "Anderson," and "Lauder."

A substring index is the most resource-intensive to create and maintain.

Attribute
Every index must have an attribute, because search matches are performed using schema attributes. If the attribute field appears blank, then the attribute still exists but is hard-coded into the system.

Add
Allows you to create a user-defined index. You can specify the index name, attributes, and rule.

Delete
Deletes the selected User or Auto Added index. An Operational index cannot be deleted.

Other Servers
Allows you to copy the selected User or Auto Added index definition to another server on the same tree. Also allows you to remove index definitions from other servers.

Take Offline/Bring Online
Allows you suspend or activate User and Auto Added indexes..
