If you wish to apply NATIVE authentication to a database that was created without it, the procedure is slightly different depending on whether you specify NATIVE:credentialsDB or NATIVE:credentialsDB:LOCAL. user authenticationNATIVE authentication NATIVE authenticationconverting a database to use

• If you specify NATIVE:credentialsDB, add users of the existing database to the credentialsDB. For instance, if the old database was created without any authentication, then its default user name is APP, and you could do the following: CALL SYSCS_UTIL.SYSCS_CREATE_USER('app', 'app');
• If you plan to specify NATIVE:credentialsDB:LOCAL, first connect to the existing database as its Database Owner using its old authentication scheme. Call SYSCS_UTIL.SYSCS_CREATE_USER to add credentials for the Database Owner. For example, if the existing database was created with no authentication, the Database Owner is APP, and you would add credentials for APP as shown above.
