Few more things in automatic scheduling

Question

does manage scheduler has all the privilege,,,,,,,means create job,,,,execute,,,,and alter,,,or we still provide them with these privileges
what does it mean,,,,,jobs can be defined with service affinity(they should run on a specific service)as opposed to an instance affinity(they should run on specific instance),,,,,,,,,, i read this line in ocp administration II study guide by doug stuns, tim butterbaugh from sybex
and the oracle press book says,,,,The service that a job class belongs to specifies that the jobs in this class will have affinity to the
particular service specified. In an Oracle Real Application Clusters (RAC) environment, this
means that the jobs in this class will only run on those database instances that are assigned to the
specific service. To balance the load on your system and for better performance, you can specify
the Service Name of the service where you want a job to run.
If no service is specified, the job class will have no service affinity and any one of the database
instances within the cluster might run the job. You can only specify service affinity for a job
class, not for individual jobs.
what does they means by service thing here,,,,and how do we specify it? or use it?
and does resource_consumer_grp and Service name parameter in job class definition are mutual exclusive?or not

Answer 1

what does they means by service thing here,,,,and how do we specify it? or use it?
Any application running in Oracle RAC clusterware is considered as a service. What is a service in the windows,its kinda same. If its a part of RAC and an application and running,its service.
Read from here about services,

If you don't know RAC yet, better is to leave it.Its the core of RAC if you ask me.
does resource_consumer_grp and Service name parameter in job class definition are mutual exclusive?or not
Did you check in the docs for the same?
