ORA-25507: resource manager has not been continuously on

 

<<Database Administrator's
Guide>>上有这样一段话:You
must have the Database Resource Manager feature activated, and it
must have been activated since instance startup (all
instances in an Oracle Real Application Clusters environment) to
successfully issue the

ALTER SYSTEM
QUIESCE RESTRICTED

statement. It is through the
facilities of the Database Resource Manager that non-DBA sessions
are prevented from becoming active. Also, while this statement is
in effect, any attempt to change the current resource plan will be
queued until after the system is unquiesced.
