If a job is running when you close a window, the job will continue to run to its completion. However, if you created a job with the STOP_ON_WINDOW_CLOSE attribute set to TRUE, that running job will close upon the closing of its window. To disable a window, you use the DISABLE procedure, as shown here: SQL> EXECUTE DBMS_SCHEDULER.DISABLE (NAME => 'BACKUP_WINDOW');

You can only disable a window if no job uses that window or if the window isn t open. If the window is open, you can disable it by using the DISABLE procedure with the FORCE=TRUE attribute. You can drop a window by using the DROP_WINDOW procedure. If a job associated with a window is running, a DROP_WINDOW procedure will continue to run through to completion, and the window is disabled after the job completes. If you set the job s STOP_ON_WINDOW_CLOSE attribute to TRUE, however, the job will immediately stop when you drop an associated window. If you use the FORCE=TRUE setting, you ll disable all jobs that use that window.

You can map each Scheduler job class to a specific resource consumer group. A resource plan is assigned to a resource consumer group, and thus indirectly to each job class as well, by the Database Resource Manager. The active resource plan (as determined by the currently open window) will apportion resources to groups, giving different levels of resources to different jobs, based on their job class. The Scheduler works closely with the Database Resource Manager to ensure proper resource allocation to the jobs. The Scheduler will start a job only if there are enough resources to run it. Within each Scheduler window, you can have several jobs running, with varying degrees of priority. You can prioritize jobs at two levels class and job. The prioritization at the class level is based on the resources allocated to each resource consumer group by the currently active resource plan. For example, the FINANCE_JOBS class might rank higher than the ADMIN_JOBS class, based on the resource allocations dictated by its active resource plan. Within the FINANCE_JOBS and ADMIN_JOBS classes, there will be several individual jobs. Each of these jobs has a job priority, which can range from 1 to 5, with 1 being the highest priority. You can use the SET_ATTRIBUTES procedure to change the job priority of any job, as shown here: SQL> BEGIN dbms_scheduler.SET_ATTRIBUTE( NAME => 'test_job', ATTRIBUTE => 'job_priority', VALUE => 1); END; The default job priority for a job is 3, which you can verify with the following query: SQL> SELECT job_name, job_priority FROM dba_scheduler_jobs; JOB_NAME JOB_PRIORITY ------------------------------ --------------------ADV_SQLACCESS1523128 3 ADV_SQLACCESS5858921 3 GATHER_STATS_JOB 3 PURGE_LOG 3 TEST_JOB03 3 TEST_JOB1 3 6 rows selected SQL>

Since windows might have overlapping schedules, you may frequently have more than one window open at the same time, each with its own resource plan. At times like this, the Scheduler will close all windows except one, using certain rules of precedence. Here is how the precedence rules work: If two windows overlap, the window with the higher priority opens and the window with the lower priority closes. If two windows of the same priority overlap, the active window remains open. If you are at the end of a window and you have other windows defined for the same time period with the same priority, the window that has the highest percentage of time remaining will open.

A window group is a collection of windows, and it is part of the SYS schema. Window groups are optional entities, and you can make a window a part of a window group when you create it, or you can add windows to a group at a later time. You can specify either a single window or a window group as the schedule for a job. As explained earlier in this chapter, you can take two or more windows that have similar characteristics for example, some night windows and a holiday window and group them together to create a downtime window group. Window groups are used for convenience only, and their use is purely optional.
