When using the Rational Directory Server, two files are created in the data subfolder (for example, C:\Program Files\IBM\Rational\DOOORS\9.5\data\): tds_valid_id.txt and tds_registered.txt. These files are used to associate the database with a universally unique identifier (UUID).
The tds_valid_id.txt file indicates that the repository identifier that is stored in the database is a valid UUID obtained from the directory server. As long as this file is present, the database cannot be registered with a different UUID.
To deploy a copy of a database as a new database with a different UUID, delete this file. To retain the current UUID, do not delete this file.
The tds_registered.txt file indicates that the repository identifier that is stored in the database is a valid UUID that is recognized by the currently configured directory server. If this file is present, the database server does not run unless the UUID is found in the Rational Directory Server registry.
To redeploy a database with its existing UUID on a new directory server, delete this file. Make sure that the tds_valid_id.txt file is not deleted.
