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.

In earlier sections in this chapter, you ve seen how you can use the SET_ATTRIBUTE procedure to modify various components of the Scheduler. Attributes like JOB_NAME and PROGRAM_NAME are unique to the job and program components. You can retrieve the attributes of any Scheduler component with the GET_SCHEDULER_ATTRIBUTE procedure of the DBMS_SCHEDULER package.

You can use the SET_ATTRIBUTE_NULL procedure to set a Scheduler component s attributes to NULL. For example, to unset the comments attribute of the TEST_PROGRAM program, you can use the following code: SQL> EXECUTE dbms_scheduler.SET_ATTRIBUTE_NULL('TEST_PROGRAM', 'COMMENTS');

There are some attributes that are common to all Scheduler components. The SET_SCHEDULER_ ATTRIBUTE procedure lets you set these common, or global, attribute values, which affect all Scheduler components. The common attributes include the default time zone, the log history retention period, and the maximum number of job worker processes.

There are several dynamic performance views you can use to monitor Scheduler jobs, and I briefly discuss the important views here.
DBA_SCHEDULER_JOBS
The DBA_SCHEDULER_JOBS view provides the status and general information about scheduled jobs in your database. Here s a simple query using the view: SQL> SELECT job_name, program_name 2 FROM DBA_SCHEDULER_JOBS; JOB_NAME PROGRAM_NAME --------------------------------------------- --PURGE_LOG PURGE_LOG_PROG GATHER_STATS_JOB GATHER_STATS_PROG . . . SQL>
DBA_SCHEDULER_RUNNING_JOBS
The DBA_SCHEDULER_RUNNING_JOBS view provides information regarding currently running jobs.
DBA_SCHEDULER_JOB_RUN_DETAILS
You can use the DBA_SCHEDULER_JOB_RUN_DETAILS view to check the status and the duration of execution for all jobs in your database, as the following example shows: SQL> SELECT job_name, status, run_duration 2* FROM DBA_SCHEDULER_JOB_RUN_DETAILS; JOB_NAME STATUS RUN_DURATION -----------------------------------------------------------PURGE_LOG SUCCEEDED +000 00:00:02 PURGE_LOG SUCCEEDED +000 00:00:04 GATHER_STATS_JOB SUCCEEDED +000 00:31:18 SQL>
DBA_SCHEDULER_SCHEDULES
The DBA_SCHEDULER_SCHEDULES view provides information on all current schedules in your database, as shown here: SQL> SELECT schedule_name, repeat_interval 2* FROM dba_scheduler_schedules; SCHEDULE_NAME REPEAT_INTERVAL --------------------------------------------------------------------DAILY_PURGE_SCHEDULE freq=daily;byhour=12;byminute=0;bysecond=0 SQL>
DBA_SCHEDULER_JOB_LOG
The DBA_SCHEDULER_JOB_LOG view enables you to audit job-management activities in your database. The data that this view contains depends on how you set the logging parameters for your jobs and job classes. In the Creating a Job Class section, earlier in the chapter, you saw how to set the logging level for a job at the job class level. In order to set the logging levels at the individual job level, you use the
CHAPTER 18 MANAGING AND MONITORING THE OPERATIONAL DATABASE
SET_ATTRIBUTE procedure of the DBMS_SCHEDULER package. In the SET_ATTRIBUTE procedure, you can set the LOGGING_LEVEL attribute to two different values: DBMS_SCHEDULER.LOGGING_FULL DBMS_SCHEDULER.LOGGING_RUNS The DBMS_SCHEDULER.LOGGING_RUNS option will merely record the job runs, while the DBMS_ SCHEDULER.LOGGING_FULL option turns on full job logging. Here is an example showing how you can turn on full job logging at the job level: SQL> EXECUTE dbms_scheduler.set_attribute ('TESTJOB', 'LOGGING_LEVEL', dbms_scheduler.LOGGING_FULL);
Purging Job Logs
By default, once a day, the Scheduler will purge all window logs and job logs that are older than 30 days. You can also manually purge the logs by executing the PURGE_LOG procedure, as shown here: SQL> EXECUTE DBMS_SCHEDULER.PURGE_LOG( LOG_HISTORY => 1, JOB_NAME => 'TEST_JOB1');
Default Scheduler Jobs
By default, all Oracle Database 10.2 databases use the Scheduler to run the following jobs, though you can, of course, disable any of these jobs if you wish: SQL> SELECT owner, job_name, job_type FROM dba_scheduler_jobs; OWNER JOB_NAME JOB_TYPE ------------------------------ ----------------------------SYS PURGE_LOG SYS FGR$AUTOPURGE_JOB PLSQL_BLOCK SYS GATHER_STATS_JOB SYS AUTO_SPACE_ADVISOR_JOB The GATHER_STATS_JOB is responsible for automatic optimizer-statistics collection. The AUTO_SPACE_ADVISOR_JOB runs the Segment Advisor on a daily basis in order to provide recommendations for segment shrinking. The new Scheduler is a welcome addition to the Oracle DBA s arsenal of tools. By providing a sophisticated means of scheduling complex jobs, it does away with the need for third-party tools or complex shell scripts to schedule jobs within the database.
