To use an instance as a directory server and store directory data, you must configure a DB2 database for the instance.
You can use Instance Administration Tool, Configuration Tool, or the idscfgdb command, to create and configure a DB2 database. You must stop the directory server before you configure or unconfigure the database. For more information about the idscfgdb command, see Command Reference.
If you choose to create the default instance with Instance Administration Tool, the DB2 database instance is also created and configured for the instance. For a proxy server instance, you do not require to configure a DB2 database.
When you configure a DB2 database for an instance, the configuration file of the instance is updated with the DB2 database information. The tool also creates database and local loopback settings.
The database and local loopback settings are created, if they do not exist. You can specify whether to create the database as a local code page database or as a UTF-8 database. The default code page that is used for DB2 database creation is UTF-8.
