Coordinating an application account’s database password change with the configuration changes across multiple application servers (Weblogic, Tuxedo, etc.) is a challenging task. The consequence of an unexpected event during the process can result in service disruption.
This enhancement is to allow a period of overlap where both the old and new passwords will be accepted for authentication on the database for a user/schema’s connections. Supporting views would allow the DBA to ensure that no sessions are connecting with the old password before it is disabled.
