• The attributes of each database that you use to store directory data, including
the server configuration data in the
NetscapeRoot
database. On these
databases, you can change the following attributes to improve performance:
❍
The maximum number of entries you want the server to keep in memory
(maximum entries in cache attribute)
❍
The amount of memory you want to make available for cached entries
(memory available for cache attribute)
To configure the default database attributes that apply to all other database
instances:
1.
On the Directory Server Console, select the Configuration tab, then in the
navigation tree expand the Data Icon, and highlight the Database Settings
node.
This displays the Database tabs in the right pane.
2.
Select the LDBM Plugin Settings tab in the right pane.
This tab contains the database attributes for all databases stored on this server.
3.
In the Maximum Cache Size field, enter a value corresponding to the amount
of memory that you want to make available for all databases.
4.
In the look-through limit field, enter the maximum number of entries you want
the server to check in response to a search request.
If you do not want to set a limit, type
-1
in this text box. If you bind to the
directory as the Directory Manager, by default the look-through limit is
unlimited, and overrides any settings you specify here.
To configure the attributes of each database that stores your directory data:
1.

database.
