Lab 12.2: Creating a Job Window

This lab shows you how to create and use a job window in the Scheduler. Here are the steps:

1.Create a simple resource plan.

2.Create a job schedule.

3.Create a job window to utilize the resource plan.

4.Open the job window explicitly.

5.Close the job window explicitly.

Here’s a specific example:

1.Create a simple resource plan.

SQL>begin

dbms_resource_manager.create_simple_plan(simple_plan => ‘LNE_PLAN1’, consumer_group1 => ‘LNEGROUP1’, group1_percent => 80, consumer_group2 => ‘LNEROUP2’, group2_percent => 20);

end;

/

2.Create a job schedule.

SQL>begin dbms_scheduler.create_schedule(

schedule_name => ‘NIGHTLY_BATCH_SCHEDULE’, start_date => SYSTIMESTAMP, repeat_interval => ‘FREQ=DAILY; BYHOUR=20’, comments => ‘Runs nightly at 9:00 PM’); end;

3.Create a job window to utilize the resource plan.

SQL>begin dbms_scheduler.create_window (

window_name => ‘NIGHTLY_BATCH_WINDOW’, resource_plan => ‘LNE_PLAN1’, schedule_name => ‘NIGHTLY_BATCH_SCHEDULE’, duration => INTERVAL ‘10’ HOUR, window_priority => ‘HIGH’);

end;

/

4.Open the job window explicitly for a 10-hour duration.

SQL>begin dbms_scheduler.open_window (

window_name => ‘NIGHTLY_BATCH_WINDOW’, duration => INTERVAL ‘600’ MINUTE, force => TRUE);

end; SQL> /

PL/SQL procedure successfully completed.

5.Close the job window explicitly.

SQL> begin dbms_scheduler.close_window (

window_name => ‘NIGHTLY_BATCH_WINDOW’); end;

SQL> /

Lab 13.1: Using the Locale Builder to Create a New Linguistic Sort

This lab was created using Windows XP. However, it should also work using Unix (and in fact was tested using Linux).

This lab shows you how to use the Oracle Locale Builder to create a new linguistic sort.

1.Open Oracle Locale Builder.

2.Choose to create a new file, and then choose Linguistic Sort.

3.Select Monolingual Linguistic Sort.
