Stop a Workflow Background Engine
Hi, i have set a scheduled background process that runs every minute for test purposes, however,
now that i don't need it anymore, i would want it to be deactivated.
It keeps sending me notifications that the process has completed (i've set it that way), and my inbox is getting full because of it. hehe.
any help?
thanks!
I figured it out. it's just as simple as a concurrent program with a scheduled run. so i went into system administrator, found the scheduled request, and terminated it.

How to use Workflow Background Engine in Oracle Apps?
I have created the development of a custom workflow,tested it in Developer studio in Workflow administrator and has been working correctly. I was hoping to implement this workflow using Workflow background process Concurrent request and move to production.Unfortunately when submititng the concurrent request I am not receiving any notification eventhough all the time Concurrent request always completes normal.(Also when submitting as concurrent request workflow is not prompting for the itemkey). Is it not possible to implement a workflow in the application using background concurrent process? Any help is appreciated.
Please note that Workflow Background engine is used to process workflows that are in deferred status. It is not used to launch the workflow. You will have to write your own code to launch the Workflow using one of the following methods.
1. Use WF_ENGINE.CreateProcess and WF_ENGINE.LaunchProcess APIs.
2. Register a Business Event, create a subscription to the event to launch the workflow and raise the Business Event from your code.
Workflow Background Engine has parameters such as Itemtype, Min and Max Thresholds, Process Deferred, Process Timeout and Process Stuck... which basically determine the type of background work it has to do.
Please refer to Workflow Developer Guide on how to launch Workflows and the uses of Workflow Background Engine.
Thanks

Workflow Agent Listener and Workflow Background Engine
Hi all,
I try to update roles via User Management responsibility but when applying them it throws the following warning: "Updates to Role data will not be visible in the application until the following processes are started : Workflow Agent Listener and Workflow Background Engine". So, my question is via which responsibility i can submit those requests and is there anything else i should know before creating, update roles and assigning permissions to them?
Thanks in advance,
Alexander.I checked the requests and i found that Workflow Background Engine completed successful. Only Open Period Balance finished with error but is it possible this to be the reason of the given warning? I believe not.
And pls kindly explain what exactly means "you may need to log a SR."? Create a Service Request (SR) in My Oracle Support website so you get a help from Oracle Support Engineer (assuming you have a valid CSI number and MOS account) -- https://support.oracle.com
Thanks,

Workflow background engine in Oracle inventory responsibility
12.0.6
we have scheduled Po approval and requisition in workflow backgraound engine to run every 5 mins which routes our Po`s and Req
But Workflow background engine has more than 100 item types
what are they all used for..its requests doesnt even have any output
Can someone please explain to me abt it and refer a document too
Thanks alot>
what you mean by this
We run Po approval and Requisition item types as its needed
Do you mean that we should run all more than 100 item types regularly or what?
Can you please refer me a document for it for my understanding
You are supposed to run the workflow background process for all item types (i.e do not pick a specific item type in the concurrent program submission window). Pl see these MOS Docs

Altering Workflow background engine process frequency
Hi All,
I would like to know how to increase/lower the frequency of workflow background engine in OCS. Currently it s set to 60 secs.
Thanks in advance!
HetalWorkflow (Oracle Workflow) background engine's frequency can be changed by updating / creating a new job with the SQL command wf_engine.background() in the Workflow user (owf_mgr) schema.

CAN NO LONGER SHUT DOWN REPORTS BACKGROUND ENGINE
Hello all...
We are in the process of upgrading our apps to Developer 6.0.
Come to find out that the old method of shutting down the Reports
Background Engine programmatically no longer works. (i.e.
ORACLE_SHUTDOWN=Yes).
Any info would be very much appreciated.
Thanks
nullThe mDNSResponser error has been reported as a problem with "Back To My Mac" and sometimes with Bonjour. There are probably other causes as well, but that's a place to start. You could make sure those services are disabled and check the logs to see if the errors go away.
I suppose that activity like this could stall a shutdown also, but I usually see the shutdown problem with devices not behaving and allowing the system to do an orderly shutdown.
Another test method that could point you directly to the OS or a 3rd party application would be to create another user on your machine and see if that user has the same issues.
Just because something worked before doesn't mean that a recent update or other change hasn't caused a problem. Are you using a wireless connection or hardwired? If you are wireless then you could also stop or turn off the wireless connection before trying to shutdown to see if it could be part of the problem.
The trick to begin troubleshooting a problem is to remove the variables, see if something changes, and then decide what to do about it or look for help with that particular system or sub-system. -
How to close the report background engine programatically in developer 6.0?
Friends,
We have developed our application using Oracle Developer 6.0 as front end and Oracle 9iR2 as a back end.
whenever the user is opening the application one session is creating after that if he runs any report the report background engine is started and that engine also creating one session. So, unnecessarily two sessions are opening for a single application.
So, how can we close the report background engine programatically after the report displays all the records?
Moreover, when the user close the application, the report background engine is still open. the user has to close the report background engine manually.
so how can we solve this issue?
Thanks
Sathyguyi got this while searching but its not working.....
Problem Description
Starting reports using a RUN_PRODUCT on Windows platforms starts a
Reports Background Engine (RBE). After leaving the forms application the
background engine is still running and must be terminated by the user.
Solution Description
This is intendet behaviour.
To close the Background Engine programmatically use the Reports Runtime parameter
ORACLE_SHUTDOWN. E.g.
Perform the following actions to stop the RBE when closing the Forms
application:
1) Create a dummy report which only does e.g. a SELECT * FROM DUAL
This report has a DESTYPE=FILE and a DESNAME to e.g. C:\TEMP\DUMMY.OUT
2) In the POST-FORMS trigger add the following code:
DECLARE
pl_id ParamList;
BEGIN
pl_id := Create_Parameter_List('dummy');
Add_Parameter(pl_id,'ORACLE_SHUTDOWN',TEXT_PARAMETER,'Yes');
Add_Parameter(pl_id,'PARAMFORM',TEXT_PARAMETER,'NO');
Run_product(REPORTS,'<<name dummy rapport>>',SYNCHRONOUS, RUNTIME,
FILESYSTEM,pl_id,NULL);
END;
Explanation
The Report Background Engine runs separately from the Forms application and
there is no direct relation between these processes. The Forms should signal
the RBE that is being closed.
When the Form is closed the POST-FORM triggers sends a dummy report to
the RBE. Since the ORACLE_SHUTDOWN=Yes parameter is used after running the
report the RBE is terminated.
A small side-effect of the solution is that a small file (5Kb) is created on
the file-system contaning the output of the dummy report. -
Workflow (Process Engine) is blocked with Check FM
I use BPM and it generates a Workflow with Check Function Module at the beginning. This FM is SWF_XI_CHECK_PROCESS_START and stops with exception. Then the Process Engine stop without doing anything.
Does someone know how I can solve this problem ?
What does this FM and what for ?
Message was edited by: Franck VIDILHi Udo,
In the monitoring, I have lines (one for each incomming messages) but each are with PE with green flag.
I use a correlation, the value in it is correct between the messages, but the BPM flow stopped without Workflow because of this Check FM I suppose.
Do you know if this Check FM is linked with correlation ?

Franck. -
Deferring to the Background Engine
Hi,
We are using standalone workflow. We have an activity that we defer to the background engine by setting the cost to be above the threshold of 50. We have submitted a DBMS_JOB which calls
wf_engine.background(null,50,null,true,false);
every 5 minutes. This does indeed process the deferred activity. We have a situation however where we would like to launch 4 processes each of which has a deferred activity. The background engine processes each activity sequentially whereas we would like the 4 processes to be processed at the same time. Is this possible?
Thanks,
GavinGavin,
You could use the "deferred tread" function from the standard wordflow lib (WF_STANDARD) in stead of raising the costs to above 50. After this deferred thread function you can model paralel functions. If you would like to wait for all parallel processes to complete before continueing your flow you should also use the "and" function also from the standard workflow lib.
Greetings,

Error calling background engine!!!
Hi guys!!
can you help me???
Status row for item 'WFEVDEME/PO345345', activity ID '228'
This is the error when i4m launching the background engine!!!
The Item Type WFEVDEME doesn4t exists.Why the sqlplus are returning this error????
cheersHi
I can4t purge that itemType because is not there, I purge that item type but when i4m lauching the background engine it still make this error...
ERRO na linha 1:
ORA-20002: 3101: Status row for item 'WFEVDEME/PO55555', activity ID '228' does
not exist.
ORA-06512: na "OWF_MGR2.WF_ENGINE", linha 2753
ORA-06512: na linha 5
But that item type dosen4t exists...
please help me...
If you are on a Production system and are getting this kind of error, please log an iTAR on Oracle Metalink.
If this is just a development system, might be just as easy to purge the WFEVDEME itemtype using the wfrmtype.sql script. See the Workflow Guide for details. -
How to start a background engine
When I use wfbkg.sql to start a background engine, it says wf_engine.Background has not been identified. What should I do? And is it necessary to use background engines?
thanks,
AliceHi,
What version of workflow are you using? What user are you running the script as?
In standalone workflow, login as your workflow user (default user is owf_mgr but this can change during installation), and you should be able to run it. Either that or just run
exec wf_engine.backgroundfrom SQL*Plus.
In Apps, you should schedule the job through concurrent manager as Workflow Administrator.
You only need to run a background engine if you have any processes which are not going to timeout, defer to the background, or get stuck (where the correct path cannot be determined). If you aren't deferring or having timeouts, then you don't need to run a background engine at all - my first multi-million pound Workflow implementation didn't have any background engines, but this is more the exception than the norm.
HTH,
Matt
