Database Resource Manager
in the Oracle 10g database
Introduction
Oracle Database 10g
introduces new features to the Resource Manager for managing your
resources. For example: if you want that the PMON process kills
sessions that are idle for longer than 600 seconds and kills sessions
that are idle for more than 300 seconds and are blocking other
sessions, then you should use the DBMS_RESOURCE_MANAGER package. We
assumed that you have already defined your plan as ‘MY_DAY_PLAN’
and your group as ‘MY_FIRST_GROUP.’
SQL> BEGIN
DBMS_RESOURCE_MANAGER.create_plan_directive
(
PLAN => ‘MY_DAY_PLAN’,
GROUP_OR_SUBPLAN => ‘MY_FIRST_GROUP’,
COMMET => ‘Limit user
idle time’,
MAX_IDLE_TIME => 600,
MAX_IDLE_BLOCKER_TIME =>
300);
END;
