Resource Manager problems

Question

Hi All,
I've tried to create plan using :
DBMS_RESOURCE_MANAGER.CREATE_SIMPLE_PLAN(SIMPLE_PLAN => 'ESERVICE_RSRC_PLAN');
Without specyfying groups, so i've got an error.
Next when i've tried to create plan again using :
execute DBMS_RESOURCE_MANAGER.CREATE_SIMPLE_PLAN(SIMPLE_PLAN => 'ESERVICE_RSRC_PLAN',CONSUMER_GROUP1 => 'SYS_GROUP', GROUP1_CPU => 100,
CONSUMER_GROUP2 => 'OTHER_GROUPS', GROUP2_CPU => 100);
I've got an error ora-29364 saying that :
'plan directive ESERVICE_RSRC_PLAN, SYS_GROUP already exists'
So when i've tried to delete directive using :
EXECUTE DBMS_RESOURCE_MANAGER.DELETE_PLAN_DIRECTIVE (plan => 'ESERVICE_RSRC_PLAN',group_or_subplan => 'SYS_GROUP');
I've got an error :
ORA-29358: resource plan ESERVICE_RSRC_PLAN does not exist
Appreciate for any help.
Best Regards Arkadiusz Masny

You have two issues,
DBMS_RESOURCE_MANAGER.CREATE_SIMPLE_PLAN will create a simple resource manager plan with new groups you have to use new group names for it to work.
The total CPU at each level must total 100, to use a simple plan the following will work..
execute DBMS_RESOURCE_MANAGER.CREATE_SIMPLE_PLAN
(SIMPLE_PLAN => 'ESERVICE_RSRC_PLAN',
CONSUMER_GROUP1 => 'NEW_GROUP_1', GROUP1_CPU => 90,
CONSUMER_GROUP2 => 'NEW_GROUP_2', GROUP2_CPU => 10);
to use the existing group the follwoing SQL should work (NB I copied and pasted out of dbconsole, trying to manage this stuff using SQL is too much typing...)
BEGIN
dbms_resource_manager.clear_pending_area();
dbms_resource_manager.create_pending_area();
dbms_resource_manager.create_plan( 'ESERVICE_RSRC_PLAN', '');
dbms_resource_manager.create_plan_directive(
plan => 'ESERVICE_RSRC_PLAN2',
group_or_subplan => 'OTHER_GROUPS',
comment => '',
cpu_p1 => 10, cpu_p2 => NULL, cpu_p3 => NULL, cpu_p4 => NULL,
cpu_p5 => NULL, cpu_p6 => NULL, cpu_p7 => NULL, cpu_p8 => NULL,
parallel_degree_limit_p1 => NULL,
active_sess_pool_p1 => NULL,
queueing_p1 => NULL,
switch_group => '',

switch_estimate => false,
max_est_exec_time => NULL,

dbms_resource_manager.create_plan_directive(

END;
