Where is sp start job

Connect and share knowledge within a single location that is structured and easy to search. This article describes an SP to launch a sql agent job and wait. It's normally used to detect long running jobs. I actually had to do this recently, and this is how I'm thinking of implementing it.

However, it does work:. Of course, you'll want to put in some code to ensure that there's a max number of times this will recurse, but you get the idea. You could also pass in a parameter to control how often the recursion happens.

In my case, after ten seconds, the results are meaningless. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams? Collectives on Stack Overflow. For example, the following statement drops two windows:. For example:. A job with a disabled window group as its schedule does not run when the member windows open. Disabling a window group does not disable its member windows. You can also disable several window groups in one call by providing a comma-delimited list of window group names.

For example, the following statement disables three window groups:. The Database Resource Manager Resource Manager controls how resources are allocated among database sessions. It not only controls asynchronous sessions like Scheduler jobs, but also synchronous sessions like user sessions.

It groups all "units of work" in the database into resource consumer groups and uses a resource plan to specify how the resources are allocated among the various consumer groups.

For Scheduler jobs, resources are allocated by first assigning each job to a job class, and then associating a job class with a consumer group. Resources are then distributed among the Scheduler jobs and other sessions within the consumer group. You can also assign relative priorities to the jobs in a job class, and resources are distributed to those jobs accordingly.

You can manually change the current resource plan at any time. Another way to change the current resource plan is by creating Scheduler windows.

Windows have a resource plan attribute. When a window opens, the current plan is switched to the window's resource plan. The Scheduler tries to limit the number of jobs that are running simultaneously so that at least some jobs can complete, rather than running a lot of jobs concurrently but without enough resources for any of them to complete.

The Scheduler and the Resource Manager are tightly integrated. The job coordinator obtains database resource availability from the Resource Manager. Based on that information, the coordinator determines how many jobs to start. It will only start jobs from those job classes that will have enough resources to run. The coordinator will keep starting jobs in a particular job class that maps to a consumer group until the Resource Manager determines that the maximum resource allocated for that consumer group has been reached.

Therefore, there might be jobs in the job table that are ready to run but will not be picked up by the job coordinator because there are no resources to run them. Therefore, there is no guarantee that a job will run at the exact time that it was scheduled. The coordinator picks up jobs from the job table on the basis of which consumer groups still have resources available.

The Resource Manager continues to manage the resources that are assigned to each running job based on the specified resource plan. Keep in mind that the Resource Manager can only manage database processes.

The active management of resources does not apply to external jobs. The following example illustrates how resources are allocated for jobs. Figure offers a simple graphical illustration of this scenario. This resource plan clearly gives priority to jobs that are part of job class JC1.

Note that resources that remain unused by one consumer group are available from use by the other consumer groups. You can view information about job runs, job state changes, and job failures in the job log. The job log shows results for both local and remote jobs.

The job log is implemented as the following two data dictionary views:. Depending on the logging level that is in effect, the Scheduler can make job log entries whenever a job is run and when a job is created, dropped, enabled, and so on. For a job that has a repeating schedule, the Scheduler makes multiple entries in the job log—one for each job instance.

Each log entry provides information about a particular run, such as the job completion status. Log entries for job runs are not made until after the job run completes successfully, fails, or is stopped.

The following example shows job log entries for a complete job lifecycle. After the first successful run, the job is enabled again, so it runs once more. It is then stopped and dropped. You can consult the run details views to determine why a job failed or was stopped. If the logging level of the job class is higher than that of a job in the class, then the logging level of the job class takes precedence. Thus, by default, all job runs are recorded in the job log.

For job classes that have very short and highly frequent jobs, the overhead of recording every single run might be too much and you might choose to turn the logging off or set logging to occur only when jobs fail.

However, you might prefer to have a complete audit trail of everything that happens with jobs in a specific class, in which case you would enable full logging for that class.

To ensure that there is an audit trail for all jobs, the individual job creator must not be able to turn logging off. The Scheduler supports this by making the class-specified level the minimum level at which job information is logged.

A job creator can only enable more logging for an individual job, not less. This functionality is provided for debugging purposes. For example, if the class-specific level is set to record job runs and logging is turned off at the job level, the Scheduler still logs job runs. If, however, the job creator turns on full logging and the class-specific level is set to record runs only, the higher logging level of the job takes precedence and all operations on this individual job are logged.

This way, an end user can test his job by turning on full logging. For example, to turn on full logging for a job called mytestjob , issue the following statement:. For multiple-destination jobs, the overall parent job state depends on the outcome of the child jobs. Due to situations that might arise on some destinations that delay the start of child jobs, there might be a significant delay before the parent job state is finalized.

For repeating multiple-destination jobs, there might even be a situation in which some child jobs are on their next scheduled run while others are still working on the previous scheduled run. Eventually, however, lagging child jobs may catch up to their siblings, in which case the final state of the parent job can be determined. Table Table lists the contents of the job monitoring views for multiple-destination jobs. One entry for each child job when the child job completes, and one entry for the parent job when the last child job completes and thus the parent completes.

This ID represents the unique combination of a job, a credential, and a destination. You can configure a job so that the Scheduler raises an event when the job changes state. The Scheduler can raise an event when a job starts, when a job completes, when a job exceeds its allotted run time, and so on. The consumer of the event is your application, which takes some action in response to the event.

For example, if due to a high system load, a job is still not started 30 minutes after its scheduled start time, the Scheduler can raise an event that causes a handler application to stop lower priority jobs to free up system resources.

The Scheduler can raise job state events for local regular jobs, remote database jobs, local external jobs, and remote external jobs.

No progress will be made in the chain unless there is manual intervention. The job's schedule limit was reached. By default, a job does not raise any job state events.

When raising a job state change event, the Scheduler enqueues a message onto a default event queue. Your applications subscribe to this queue, dequeue event messages, and take appropriate actions. After you enable job state change events for a job, the Scheduler raises these events by enqueuing messages onto the Scheduler event queue SYS.

This queue is a secure queue, so depending on your application, you may have to configure the queue to enable certain users to perform operations on it. See Oracle Streams Concepts and Administration for information on secure queues.

To prevent unlimited growth of the Scheduler event queue, events raised by the Scheduler expire in 24 hours by default. Expired events are deleted from the queue. Each bit flag represents a different job state to raise an event for. For example, turning on the least significant bit enables job started events to be raised. It enables the following event types, both of which indicate some kind of error. To consume job state events, your application must subscribe to the Scheduler event queue SYS.

This queue is a secure queue and is owned by SYS. To create a subscription to this queue for a user, do the following:. There is no need to grant dequeue privileges to the user. If it is NULL , an agent is created whose name is the user name of the calling user. This call both creates a subscription to the Scheduler event queue and grants the user permission to dequeue using the designated agent. The subscription is rule-based.

The rule permits the user to see only events raised by jobs that the user owns, and filters out all other messages. After the subscription is in place, the user can either poll for messages at regular intervals or register with AQ for notification. The Scheduler event queue SYS. You can configure a job to send e-mail notifications when it changes state.

The job state events for which e-mails can be sent are listed in Table E-mail notifications can be sent to multiple recipients, and can be triggered by any event in a list of job state events that you specify.

You can also provide a filter condition, and only job state events that match the filter condition generate notifications. You can include variables like job owner, job name, event type, error code, and error message in both the subject and body of the message. The Scheduler automatically sets values for these variables before sending the e-mail notification. You can configure many job state e-mail notifications for a single job. The notifications can differ by job state event list, recipients, and filter conditions.

For example, you can configure a job to send an e-mail to both the principle DBA and one of the senior DBAs whenever the job fails with error code or You can also configure the same job to send a notification to only the principle DBA if the job fails to start at its scheduled time. When you specify multiple recipients and multiple events, each recipient is notified when any of the specified events is raised. All other arguments have defaults.

The default sender is defined by a Scheduler attribute, as described in the previous section. The following example configures an additional e-mail notification for the same job for a different event. This example accepts the defaults for the sender , subject , and body arguments. This example could have also omitted the events argument to accept event defaults. The next example is similar to the first, except that it uses a filter condition to specify that an e-mail notification is to be sent only when the error number that causes the job to fail is or When you specify multiple recipients and multiple events, the notification for each specified event is removed for each recipient.

Running the same query as that of the previous section, the results are now the following:. If you leave the events argument NULL , notifications for all events for the specified recipients are removed. If you leave recipients NULL , notifications for all recipients for the specified events are removed. If you leave both recipients and events NULL , then all notifications for the job are removed. If you include a recipient and event for which you did not previously create a notification, no error is generated.

You can accomplish the same tasks using Oracle Enterprise Manager. Creating, Running, and Managing Jobs A job is the combination of a schedule and a program, along with any additional arguments required by the program. Creating Jobs Using a Named Program You can create a job by pointing to a named program instead of inlining its action. Creating Jobs Using a Named Schedule You can also create a job by pointing to a named schedule instead of inlining its schedule.

Creating Jobs Using Named Programs and Schedules A job can also be created by pointing to both a named program and a named schedule. Specifying Job Credentials and Job Destinations For local external jobs, remote external jobs, and remote database jobs, you must specify the credentials under which the job runs. Creating Credentials A credential is a user name and password pair stored in a dedicated database object. See Also: "Credentials" for more information about credentials.

Creating Destinations A destination is a Scheduler object that defines a location for running a job. You do not need object privileges to use a destination created by another user. To create an external destination: Register a remote Scheduler agent with the database.

You create an external destination implicitly by registering a remote agent. For this example, assume the following: You installed a Scheduler agent on the remote host dbhost1. See Also: "Destinations" for more information about destinations "Jobs" to learn about remote external jobs and remote database jobs.

Members of destination groups have the following format: [[ schema. Example Creating a Database Destination Group This example creates a database destination group. See Also: "Groups" for an overview of groups. Creating Multiple-Destination Jobs You can create a job that runs on multiple destinations, but that is managed from a single location. See Also: "Defining Program Arguments". See Also: "Detached Jobs". See Also: "Lightweight Jobs". After running, the job is dropped. Alter ing Jobs You alter a job by modifying its attributes.

Runni ng Jobs There are three ways in which a job can be run: According to the job schedule—In this case, provided that the job is enabled, the job is automatically picked up by the Scheduler job coordinator and run under the control of a job slave. Provided that job is enabled, the Scheduler runs it automatically.

Caution: When a job is stopped, only the current transaction is rolled back. This can cause data inconsistency. Stopping a Chain Job If a job pointing to a chain is stopped, all steps of the running chain that are running are stopped.

Viewing std out and stde rr for External Jobs External jobs with credentials write stdout and stderr to log files. Creating and Managing Programs to Define Jobs A program is a collection of metadata about a particular task.

Defining Program Arguments After creating a program, you can define program arguments. See Also: "Setting Job Arguments". Altering Pr ograms You alter a program by modifying its attributes. Creating and Managing Schedules to Define Jobs You optionally use a schedule object a schedule to define when a job should be run. Schedule Tasks and Their Procedures Table illustrates common schedule tasks and the procedures you use to handle them.

Examples of Cal endaring Expressions The following examples illustrate simple repeat intervals. Run every Friday. All three examples are equivalent. Next run time Using the calendaring syntax, the next time the job will run is fixed. Note that the calendar expression repeats every two hours on the hour. Repeat Intervals and Daylight Savings For repeating jobs, the next time a job is scheduled to run is stored in a timestamp with time zone column.

About Events An event is a message sent by one application or system process to another to indicate that some action or occurrence has been detected. There are two kinds of events consumed by the Scheduler: Events raised by your application An application can raise an event to be consumed by the Scheduler. File arrival events raised by a file watcher You can create a file watcher—a Scheduler object introduced in Oracle Database 11 g Release 2—to watch for the arrival of a file on a system.

However, by default, events that occur while the job is already running are ignored; the event gets consumed, but does not trigger another run of the job. In this case, an instance of the job is started for every instance of the event, and all job instances are lightweight jobs. Creating an Ev ent Schedule You can create a schedule that is based on an event. Altering an Ev ent Schedule You alter the event information in an event schedule in the same way that you alter event information in a job.

Passing Event Mess ages into an Event-Based Job Through a metadata argument, the Scheduler can pass to an event-based job the message content of the event that started the job. Starting a Job When a File Arrives on a System You can configure the Scheduler to start a job when a file arrives on the local system or a remote system.

Note: The following behaviors: The UNIX mv command does not change the file modification time, while the cp command does. Enabling File Arrival Events from Remote Systems To receive file arrival events from a remote system, you must install the Scheduler agent on that system, and you must register the agent with the database. To enable the raising of file arrival events at remote systems: Set up the local database to run remote external jobs. Install, configure, register, and start the Scheduler agent on the first remote system.

This adds the remote host to the list of external destinations maintained on the local database. Repeat the previous step for each additional remote system. Creating File Watchers and File Watcher Jobs You perform the following tasks to create a file watcher and create the event-based job that starts when the designated file arrives.

Task 1 - Create a Credential The file watcher requires a Scheduler credential object a credential with which to authenticate with the host operating system for access to the file. Perform these steps: Create a credential for the operating system user that must have access to the watched-for file. Perform these steps: Create the program. File Arrival Example In this example, an event-based job watches for the arrival of end-of-day sales reports onto the local host from various locations.

Changing the File Arrival Detection Interval File watchers check for the arrival of files every ten minutes by default. To change the file arrival detection interval: Connect to the database as the SYS user.

The following example changes the file arrival detection frequency to every two minutes. Creating and Managing Job C hains A job chain "chain" is a named series of tasks that are linked together for a combined objective. To create and use a chain, you complete these tasks in order: Task See Create a chain object Creating Chains 2. Define the steps in the chain Defining Chain Steps 3. Add rules Adding Rules to a Chain 4.

Enable the chain Enabling Chains 5. Create a job the "chain job" that points to the chain Creating Jobs for Chains.

Chain Tasks and Their Procedures Table illustrates common tasks involving chains and the procedures associated with them. Defining C hain Steps After creating a chain object, you define one or more chain steps. For an event step, the step was started and is waiting for an event.

Setting an Evaluation Interval for Chain Rules The Scheduler evaluates all chain rules at the start of the chain job and at the end of each chain step. Here are some examples: A chain step is resource-intensive and must therefore run at off-peak hours. Note: Chains are automatically disabled by the Scheduler when: The program that one of the chain steps points to is dropped The nested chain that one of the chain steps points to is dropped The event schedule that one of the chain event steps points to is dropped.

The job subname is normally the same as the step name except in the following cases: For nested chains, the current step name may have already been used as a job subname. Stopp ing Individual Chain Steps There are two ways to stop individual chain steps: By creating a chain rule that stops one or more steps when the rule condition is met.

For each step to stop, you must specify the schema name, chain job name, and step job subname. Pausing Cha ins You can pause an entire chain or individual branches of a chain. Skipping Ch ain Steps You can skip one or more steps in a chain.

See Also: "Skipping Chain Steps". Handling Sta lled Chains At the completion of a step, the chain rules are always evaluated to determine the next steps to run.

Prioritizing Jobs You prioritize Oracle Scheduler jobs using three Scheduler objects: job classes, windows, and window groups. Managing Job Priorities with Job C lasses Job classes provide a way to group jobs for prioritization.

Managing Job Scheduling and Job Priorities with Win dows Windows provide a way to automatically activate different resource plans at different times. The key attributes of a window are its: Schedule This controls when the window is in effect. Duration This controls how long the window is open. Resource plan This names the resource plan that activates when the window opens. Window Tasks and Their Procedures Table illustrates common window tasks and the procedures you use to handle them.

Altering Win dows You alter a window by modifying its attributes. Openin g Windows When a window opens, the Scheduler switches to the resource plan that has been associated with it during its creation. Opening a window manually has no impact on regular scheduled runs of the window.

When a window opens, an entry is made in the window log. Closing Windo ws There are two ways a window can close: Based on a schedule A window will close based on the schedule defined at creation time.

Managing Job Scheduling and Job Priorities with Window Groups Window groups provide an easy way to schedule jobs that must run during multiple time periods throughout the day, week, and so on. Window Group Tasks and Their Procedures Table illustrates common window group tasks and the procedures you use to handle them. Example of Resource Allocation for Jobs The following example illustrates how resources are allocated for jobs. Writing applications that receive job state events from the Scheduler See "Monitoring Job State with Events Raised by the Scheduler" Configuring jobs to send e-mail notifications upon a state change See "Monitoring Job State with E-mail Notifications" Viewing the Job Log You can view information about job runs, job state changes, and job failures in the job log.

See Also: "Monitoring and Managing Window and Job Logs" for more information about setting the job class logging level. Monitoring Multiple Destination Jobs For multiple-destination jobs, the overall parent job state depends on the outcome of the child jobs.
