OCI-01997
GRANT failed: user 'string' is IDENTIFIED GLOBALLY
Cause
An attempt was made to grant administrative privileges to a user account, which was created as IDENTIFIED GLOBALLY. This is only allowed in an ASM; not in a database instance.
Action
When connected to a database instance, try granting the administrative privilege to a user whose account is managed by the database (as opposed to managed by a directory server, as is the case with accounts which are IDENTIFIED GLOBALLY).
