Scope

The Starter means is used to start a Job Stream. The Starter starts the a Job Streams Stream based on the basis of run-time provided to it (the starter Starter can also be started manually also using the "Start Now" operation from it's action menu). The Starter when it starts the Job Stream it creates an instance of the Job Stream called Session. Each session of the Job Stream instance has its own Instance ID. The events Events are now created on a session basis. The created per instance. An event created with Session e.g. Instance A does not have access to Session Instance B, the two -session instances are independent even if they are of used in the same job StreamsJob Stream.

Advantages of Job

...

Stream Starter

The Starter adds new a number of advantages to the Job Streams:

1. Assigning Run-time to the

   starter

   Starter

   The Job Stream Starter allows assigning a run-time to the Job Stream. Earlier it was not possible to run a Job Stream more than once without using the "Reset Job Stream but now " operation. Now we can run the Job Stream more than once for , e.g. every 5 minutes. From release 1.13.4 we We don't need to specify the run-time to with the first job of the Job Stream and then to make other jobs in the Job Streams Stream start accordingly. 
   A Job Stream can even have more than one Starter and can have different run-time times assigned to each starterStarter.

2. Assigning Parameters to the

   starter

   Starter

   The Job Stream Starter can have carry a set of parameter parameters, i.e. we can assign parameters to the Starter and that the parameters will be available to each job in the Job Stream. The parameter parameters can only be accessed by the job in the Job Stream instance which is created by this Starter. For example, a parameter [name': 'value1'] will be available for each job of the Job Stream if it is assigned to the Starter. Without the Starter, we need to define the parameters for each job in the Job Stream.

3. Starting more than 1

   job

   Job at a specific time

   The Job Stream Starter is assigned to the first of job in the Job Stream. If there is more than one job that starts should start at begin of the Job Stream at the same time then we need to assign Run-Time on each job differently. But with the Starter, we can assign the starter to jobs and all the jobs can assign the Starter a number of jobs that will be executed in parallel at the specified run-time.

4. Specific Job Stream

   history

   History for each run

   The Job Stream when now executed with the Starter creates an instance of Job Stream called the session. Each created session has with its own Session Instance ID. The Job Stream now stores the history of each session, so from the release 1.13.4 Job Stream has a specific history for each run which was earlier not possibleinstance run is stored individually.

5. Access

   to the event for one complete run of Job Stream 

   Events within the scope of a Job Stream run 

   The Job Stream starter when creates a session then the Starter instance is the scope for which events are created for this session. And the events . Events can be accessed until as long as the Job Stream execution is not completed, i.e. we can access the event for the lifetime of one job stream run. Earlier the events for the Job Streams where only accessible for today i.e. the event cannot access with the expression <event_name> once the period gets completed.a Job Stream run.
   Please refer to Scope of Events for reference.

6. Accessing

   the events

   Events from another Job Stream 

   The Until release 1.13.3 the event eventA, when created in a Job Stream jsstreamA jsStreamA, can be consumed by all the InConditions all In Conditions in all the Job Streams using the expression eventAtill the release 1.13.3. To access the events from another Job Stream in release 1.13.4 we need have to address reference the Job Stream, i.e. from 1.13.4 when using the eventA created in jsstreamA need jsStreamA it has to be accessed with the expression jsstreamAjsStreamA.eventA.

How to create a Job Stream Starter

The Starter can be added either in two ways. It can be created either at the time of added either when creating the Job Stream or it can be added to the an existing Job Stream.

5. Click on the Submit button to add the Job Stream.
   
   
6. For example: When we click on the submit button , with the below details then a Job Stream will be created with a name jobstream1 with a starter name JSStarter. The Starter includes on job /testcase1/job1 with a delay of 10 seconds i.e. when the starter Starter is started then the job /testcase1/job1 will be executed after 10 seconds later.
   
   
   
   
   

Note: The A Job Stream requires a minimum of one Starter. We cannot create a Job Stream without a Starter.

Adding

a Starter to an existing Job Stream

1. Click on the action menu of the job stream name from the right panel and select Add New Starter.
   
   
   
2. A Create New Job Streams Starter Menu opensA window opens to create a new Starter.
   
   
   
3. Add the details for the starter Starter and click on submitthe Submit button.
   
   
4. For example, if we added add another starter Starter to the an existing Job Stream jobstream1 which we created in the above example with the details Title: JSSTarter2JSStarter2, Job Name: /testcase1/job2 then the starter Starter will be added to the Job Stream like this.
   
   
   Note: We can add two or more starters Starters to the same job also.
   

How to start the Job Stream

...

Starter

Whenever When a Job Stream starter Starter is started then it creates a new sessioninstance. This session instance has its own events, i.e. if the same Job Stream is run executed twice then two sessions instances will be created with a timestamp (say session instance A and session instance B). If any event is created in session instance A then it this does not reflects session affect instance B.

Selecting

The Starter when started it creates a session. Every session is stored and each session has its own execution of Job Streamcreates an instance. You can view the session by clicking on the Starter Atsee the instances when using the Started At date range. It will display the list of session instances created between the dates specified in by From and To.

a Job Stream Starter

The parameters added in the starter to a Starter are accessible by to all jobs in the whole Job Stream. Every Job in that session used all Each job in an instance can access the parameters assigned to the starter Starter throughout the Job Stream run. 

The parameter parameters can be added in two ways. It : they can be created either at the time of when creating the Job Stream or they can be added to the an existing Job Stream.

Note: If the a job contains its own parameter than both the parameters(starter and job) are parameters then both parameter sets (from Starter and from job) can be used by the job at the time of execution.

a Run-time to the Job Stream Starter

The Runtime added in the starter run-time added to a Starter is used to start the JobStream Job Stream automatically at the given time or at any period. The parameter can be added in two ways. It can be created either at the time of creating the Job Stream or can be added to the existing Job Stream.

Note: If the a job in a Job Streams Stream contains its own runtime run-time and the starter Starter starts the execution then it waits for the runtime run-time of the job. But as the job will be executed by JobScheduler so it Master its execution will not be unknown for known to the Job Streams Stream instance, i.e. the event events created by this job cannot be accessed in a sessionby this instance.

The new tab Sessions are added to the history view of the Job Streams. This includes the history of sessions with the session name, the current status of the session (running or completed), and the session ID. From the session tab, you can check whether the current session is still running or it has executed the Job Stream completely. If the value of Running=yes it means that the job Streams is still running for that session and has not been completed yettab Instances displays Job Stream instances that are executed for the selected date range. Clicking on an instance will open the Task History tab for that instance.
