Change log management for a directory server instance

Edit online

You can configure the change log database to record changes to the schema or directory entries of an instance.

The change log records all update operations, such as add, delete, modify, and modrdn, against a directory server instance. You can use client utilities to retrieve the change log data that is recorded when changes are made to a directory server database.

You can use Configuration Tool or the command-line utilities to enable or disable the change log database. You must stop the directory server before you configure or unconfigure the change log database.

To configure the change log for a directory server, use the idscfgchglg command. To unconfigure the change log for a directory server, use the idsucfgchglg command. You cannot configure a change log database for a proxy server instance.

To configure the change log for a directory server instance, you must meet the following criteria:

  1. A DB2® instance with the same name as the directory server instance must exist.
  2. You must configure a database for the directory server instance.
  3. On AIX® and Linux™, the local loopback service must be registered in the /etc/services file.

When you configure a change log database, it is created in the same database instance as the directory server instance database. For the change log database, an additional 30 MB of hard disk space is required. When you configure the change log, the change log entry is added to the configuration file of the directory server instance.
