ActiveBatch Oracle Database Job Scheduler Integration

A job is a combination of a schedule (the frequency of job execution) and a program. There may also be additional arguments the program requires. The kind of is defined by the job-Type while what the job does is defined by the job_action. A job can perform a task defined by PL/SQL block, stored procedure, chain, external script, and program.
To name a job, follow SQL naming rules to name Scheduler objects in the DBMS_SCHEDULER package. To create multiple jobs, you can select JOB_NAME from USER_SCHEDULED_JOBS after defining jobs and adding them to the array. When selecting the end_date for the job to no longer run, the job will be dropped if auto_drop is TRUE. If it is FALSE, the job will be disabled and the STATE set as COMPLETED.
To alter, run, copy, drop, stop, disable or enable a job, you must be the job owner. You cannot select owners other than the user in whose schema the job was created. Discover ActiveBatch’s reliable, powerful, and extensive job scheduling.

Oracle Scheduler helps simplify hundreds or thousands of tasks, and is implemented by the DBMS_Scheduler package.

• To create one job type the command BEGIN DBMS_SCHEDULER.CREATE_JOB procedure; for multiple jobs, use DBMS_SCHEDULER.CREATE_JOBS procedure. Some job attributes can be assigned in the CREATE_JOB procedure, but others must be set with DBMS_SCHEDULER.SET_ATTRIBUTE.
• To create a job in another schema, simply specify schema.job_name. Once a job is created, it can be queried with the *_SCHEDULER_JOBS views. DBA_SCHEDULER_JOBS will display all information pertaining to Scheduler jobs in the database.
• To drop one or more jobs in one or more job classes, use the syntax DBMS_SCHEDULER.DROP_JOB.

• To create a credential for the job to use, input exec DBMS_scheduler.CREATE_CREDENTIAL
• By default, jobs are disabled when created. Enable it with the procedure DBMS_SCHEDULER.ENABLE. To disable procedures or a job, use DBMS_SCHEDULER.DISABLE.
• Job Classes define jobs by resource consumer group and database service name. Associating a job with a Job Class helps you manage the resources a Job can use during execution. The syntax to create a Job Class is DBMS_SCHEDULER.CREATE_JOB_CLASS.
• The procedure DBMS_SCHEDULER.STOP_JOB will stop a job.
• To return the system data, input SYSTIMESTAMP. The return type is TIMESTAMP WITH TIME ZONE.
• To schedule a UNIX/Linux shell script in DBMS_SCHEDULER, you can define an Oracle program with the location of the shell script, create a schedule for the job, and associate a job with the schedule.

Explore how you can optimize operations with ActiveBatch’s enterprise job scheduler.

With 130 production-ready job steps, ActiveBatch enhances Oracle automation capabilities for improved service levels and lower costs. Easily designate sys admins so everything continues to run smoothly. With ActiveBatch’s drag-and-drop interface, creating complex workflows is straightforward and easier than ever. Explore how ActiveBatch simplifies workload automation.

You can run job requests of divergent types, including Java classes, PL/SQL procedures, and process requests that run as forked processes. To define a start time, end time, and interval to apply to a job, use the create_schedule procedure. Learn more about ActiveBatch’s low-code automation and script optimization.

There are a few ways to monitor scheduler jobs. First, you can view the job log, which includes the data dictionary views SCHEDULERJOB_LOG and SCHEDULERJOB_RUN_DETAILS where * = {DBA|ALL|USER}. You can also query and additional data dictionary, write applications that receive state events from the scheduler, or configure jobs to send email notifications for state changes. There are many procedure parameters to set to ensure you get the information you need. If you need to define job schedulers, look in the SQL Developer Connections tab.
Or, you could monitor it all in ActiveBatch, which acts as a single point of control and central dashboard to monitor all job scheduling activity across your entire environment. Uncover ActiveBatch’s flexible monitoring, alerting, and reporting.

Use the procedure CREATE_PROGRAM to create a program. From there you can define the program_name, program_action, and program_type. To set argument values for your program, use DEFINE_PROGRAM_ARGUMENT or DEFINE_ANYDATA_ARGUMENT procedures.
Scheduler does have some predefined metadata arguments that can be passed as an argument to the program if the program logic is dependent on the Scheduler environment. If your program needs to access specific job metadata, define a special argument with the DEFINE_METADATA_ARGUMENT procedure. Be careful when setting arguments; a program can become disabled if number_of_arguments is changed so that arguments are no longer defined. Discover how ActiveBatch helps you build and automate reliable end-to-end workflows in half the time.

Yes, you can create a job that points to a named schedule rather than inlining its schedule. To do this, specify a value for schedule_name in the CREATE_JOB procedure. Do not specify values for start_date, repeat_interval, or end_date. Expressions for calendaring follow the same format. FREQ= is the frequency for the job to run; BYDAY, BYHOUR, BYMINUTE, and BYSECOND specify when jobs will run, either daily, hourly, or minutely. For example, FREQ=DAILY INTERVAL=10 is a job that runs every 10 days. FREQ=DAILY BYHOUR-16,17,18 schedules a job to run daily at 4,5, and 6 pm.
