Introduction to the User Migration Utility

The User Migration Utility is a command-line utility that enables enterprise user administrators to move their users from a local database model to an enterprise user model. You can easily migrate thousands of local and external database users to an enterprise user environment in an LDAP directory where they can be managed from a central location. The utility connects to the database using the Oracle JDBC OCI driver.

Enterprise user administrators can select for migration any combination of the following user subsets in a database:

  • List of users specified on the command line or in a file

  • All external users

  • All global users

In addition, enterprise user administrators can specify values for utility parameters that determine how the users are migrated such as

  • Where to put the migrated users in the LDAP directory tree

  • Map a user with multiple accounts on various databases to a single directory user entry

The following sections explain the migration process and the changes that occur to user schemas.

Note:

After external users are migrated, their external authentication and authorization mechanisms are replaced by directory-based mechanisms. New passwords are randomly generated for migrated users if they are mapped to newly created directory entries.
