DGM-17567
Current database session was authenticated using operating system credentials.
Cause
The current database session was authenticated using operating system credentials, for example, "CONNECT /". If a role change operation was performed, DGMGRL may not be able to connect to the participating databases to complete the role change.
Action
Re-connect to the database using an alternative authentication method, for example, database credentials, and retry the command. Note that this will not be an issue if an external passsword store, for example Oracle wallet, is being used and entries have been added to it that specify correct database credentials.
