What to do when Oracle instance information
about the Oracle instance changes, such as the instance user name
and password, you must update the Remote Agent Utility.
When Oracle RAC nodes are
added or removed, you must enter information about any changes to
instances in the Remote Agent Utility. After these changes are
entered, the Backup Exec media server discovers them.
If the changes are not
updated in the Remote Agent Utility, the error "Unable to attach to
a resource..." may appear when you run a backup job.
