What is a Concurrent Program ?
An instance of an execution file, along with parameter definitions and incompatibilities. Several concurrent programs may use the same execution file to perform their specific tasks, each having different parameter defaults and incompatibilites.
What is a Concurrent Program Executable ?
An executable file that performs a specific task. The file may be a program written in a standard language, a reporting tool or an operating system language.
What is a Concurrent Request ?
request to run a concurrent program as a concurrent process.
What is a Concurrent Process ?
n instance of a running concurrent program that runs simultaneously with other concurrent processes.
What is a Concurrent Manager ?
program that processes user’s requests and runs concurrent programs. System Administrators define concurrent managers to run different kinds of requests.
What is a Concurrent Queue ?
ist of concurrent requests awaiting processing by a concurrent manager.
What is a Spawned Concurrent program ?
Concurrent program that runs in a separate process than that of the concurrent manager that starts it. L/SQL stored procedures run in the same process as the concurrent manager; use them when spawned concurrent programs are not feasible.
LIFE CYCLE OF CONCURRENT REQUESTS
What are the phases and statuses through which a concurrent prequest runs through?
A concurrent request proceeds through three, possibly four, life cycle stages or phases:
Pending Request is waiting to be run
Running Request is running
Completed Request has finished
Inactive Request cannot be run
Within each phase, a request's condition or status may change. Below appears a listing of each phase and the various states that a concurrent request can go through.
Concurrent Request Phase and Status
Phase Status Description
PENDING Normal Request is waiting for the next available manager.
Standby Program to run request is incompatible with other program(s)
currently running.
Scheduled Request is scheduled to start at a future time or date.
Waiting A child request is waiting for its Parent request to mark it ready
to run.a report in a report set that runs sequentially must wait for
a prior report to complete.
RUNNING Normal Request is running normally.
Paused Parent request pauses for all its child requests to complete. For
example, a report set pauses for all reports in the set to complete.
Resuming All requests submitted by the same parent request have completed
running. The Parent request is waiting to be restarted.
Terminating Running request is terminated, by selecting Terminate in the Status
field of the Request Details Zone.
COMPLETED Normal Request completes normally.
Error Request failed to complete successfully.
Warning Request completes with warnings. For example, a report is generated
successfully but fails to print.
Cancelled Pending or Inactive request is cancelled, by selecting Cancel in the
Status
Terminated Running request is terminated, by selecting Terminate in the Status
field of the Request Details zone.
INACTIVE Disabled Program to run request is not enabled. Contact your system
administrator.
On Hold Pending request is placed on hold, by selecting Hold in the Status field
of the Request Details zone.
No Manager No manager is defined to run the request. Check with your system
administrator.
What is the difference between Request group and request set ?
REQUESTS GROUPS AND REQUEST SETS
Reports and concurrent programs can be assembled into request groups and request sets.
1. A request group is a collection of reports or concurrent programs. A System Administrator defines report groups in order to control user access to reports and concurrent programs. Only a System Administrator can create a request group.
2. Request sets define run and print options, and possibly, parameter values, for a collection of reports or concurrent program. End users and System Administrators can define request sets. A System Administrator has request set privileges beyond those of an end user.
Standard Request Submission and Request Groups
Standard Request Submission is an Oracle Applications feature that allows you to select and run all your reports and other concurrent programs from a single, standard form. The standard submission form is called Submit Requests, although it can be customized to display a different title.
3. The reports and concurrent programs that may be selected from the Submit Requests form belong to a request security group, which is a request group assigned to a responsibility.
4. The reports and concurrent programs that may be selected from a customized Submit Requests form belong to a request group that uses a code.
In summary, request groups can be used to control access to reports and concurrent programs in two ways; according to a user's responsibility, or according to a customized standard submission (Run Requests) form.
