Cause: A database link is being used in the cluster database
environment that loops back to the same instance. One
session is trying to convert a lock that was obtained by the
other session.

Action: Get the more restrictive lock first. For example, if
session 1 gets a share lock and session 2 gets an exclusive
lock on the same object, get the exclusive lock first. Or,
simply use the same session to access the object.

Please add more information about this Error
