Changing priority of concurrent request

Hi
Please let me know is it possible to change the priority of a concurrent request submitted by the batch user(any particular user) only.
1)
I know we can use the profile option but that does not serve the purpose because i dont want the priority of all the other requests submitted by that user to be changed ,just for one particular concrrent request i want this to happen.
2)
From system admin also it can be done but this will make the priority of that request to change so it will be the same irrespective of the user.
Actually i want to CHANGE the priority of a concurrent request only when it is submitted by a particular user (through CONCSUB utility)and that should affect the priority of other requests submitted by that user ,they should remain as it is.

Please let me know is it possible to change the priority of a concurrent request submitted by the batch user(any particular user) only.How the request is being submitted? Is it from the application or the OS or using an API?

I also believe you cannot set priority if you use CONCSUB for a specific concurrent program under specific username.

How To Schedule a Concurrent Request on completion of a Spawned Request

As soon as the concurrent request submitted through Oracle Form(Consolidation Transfer)is completed we need to schedule another Concurrent Request which had to be kicked off automatically on completion of the First concurrent request. Since, the First concurrent request of Consolidation Transfer is a Spawned Program, the request set could not be created, to kick off the second concurrent program.
I would Appreciate if anyone can advise any solution to achieve this objective.

Hi Harish,
Doesn't matter what you need to do all you need is the hook!
a) Nice. Force the request to print and use print driver to call CONCSUB to submit your new "child" request
-- Since the Consolidation Trasnfer concurrent request could only be submitted through Consolidation Trasnfer Form only, I am not sure how we can do Force Print for this request.
GR: Set printer and style on concurrent program definition. Set profile option "Concurrent:Report Copies" to 1 (even by Forms Personalization if you want to). Sorted. Still think this is the best option.
c) Abstraction. Replace the C executable with a shell script that takes arguments and calls the C program and then submits new "child" request via CONCSUB
-- Appreciate, if you can elaborate this option. I think we can try this, with the help of your detailed input.
GR: Change the executable on the concurrent program to a host shell script under your mods application. Initially just get the shell script to capture program call and arguments. Run the program to get arguments. Next iteration, change shell script to call the C program from your shell script with correct arguments. Verify okay. Next iteration do the same plus call CONCSUB to submit request / set.
d) Nasty. Trigger on fnd_concurrent_requests to call new "child" request via fnd_request.submit_request - NB: very unsupported! Make sure trigger doesn't raise an exception.
-- On completion of the Consolidation Transfer concurrent request, we tried to submit the request set using the Trigger on Consolidation History table and/or fnd_concurrent_requests table. But it is entering into infinite loop.
GR: Need to use trigger condition to capture update of status_code to C (Completed) and other codes e.g. Warning. Personally I'd avoid this option because you have others! Although once I did use this method when I wanted absolute transparency :-)
Update: Changed "Print: Copies" to "Concurrent:Report Copies"

Gareth

How to schedule a concurrent request to run at a specified time/day?

Hi All,
How to schedule a concurrent request to run at a specified time/day (ex: Sunday 12pm)?
Thanks,
Chiru

Is this to run periodically ?
During the request submission, click schedule, choose the specific days, and click on S = Sunday.
Change the start date on the date of the sunday you want to run, eg : 15-JUL-07 14:00:00, change the end date as well.

How to open Report output in RTF format using concurrent request form.

Hi
I have created a report using BI publisher and RTF format. This report is working fine in PDF format. User can submit report using consurrent request form and can see report preview in PDF format.
Now user wants to submit another request and wants to see report output in RTF format.
User submitted a request, request successfully completed and generated a output RTF file in unix box but when user wants to see report output using concurrent request form (View Output) then window is showing raw data instead of RTF output.
Can any body tell me about solutions?
Thanks
Ravi

Hi Ravi
I did little R&D on it and found following 2 solutions.I am sure that you also find something but for my shake i am putting it here.If you already find the solution then ignore it.
I) 1st Solution
1)Change the profiles 'Viewer: Application for Text' and put value as 'Browser'
2) Change the profiles 'Viewer: Text' and put value as 'Browser'.Either change it system level or concerned user.
3) Log out from Current session and close all internet explorer application.
4) Log in again to check the result
II) 2nd Solution
1) Navigate to: Sys admin --> Install -> Viewer Options to open the Form "Viewer Options".
Do the entry as shown below:
File_Format     Mime Type               Description
RTF          application/rtf Microsoft Word(.rtf)
RTF          application/msword          Microsoft Word(.rtf)
2) Then ensure that the profile option Viewer: Application for Text is set to BLANK at the Site Level and User Level.
3) Then ensure that the profile option Viewer: Text is set to 'browser' at the Site Level.
-- It will pop-up the screen to choose application name from above two values.
Hope this will work it for you. For me i replicated the scenario and both solutions were working for me.
With Best Regards

Estimating number of concurrent requests

Hello,
I want to estimate the number of concurrent requests that my server application may need to handle.
Here are 3 approaches I tried to compute the probability of concurrent requests. Each of them gives different results, and obviously some of the results are palin wrong.
It's been a while since I've learnt probabilities, I used to be comfortable with them back then, but this time's over it seems.
Can you help me point out the flaw in the reasoning of each approach (that's for my culture), and, better yet, suggest how to correctly estimate the reasonable number of concurrent requests the server will have to handle (that's for my current problem)?
Preliminary assumptions:
Here are the figures, to fix ideas, and illustrate examples given below of the approach I took.
The application will have 1000 users, each of them issuing 10 requests per day.
Each request take approx 1 minute to be processed.
Users are supposed evenly distributed over worlwide timezones, and the requests are supposed to be evenly distributed over the time of a day (which is not true for a single given user, but is true if enough users are evenly distributed over timezones).
Users are supposed to work independantly of each other, so the probabilities of their actions are independant.
*1) Approach 1: brute linear approach:*
Each user uses 10 requests * 60s/rq = 600s of server time per day.
1000 users therefore use 600,000 seconds of server time; as there are 86400s per day, in average the server is serving *600K/86,K = approx 7* request at any instant of the day.
*2) Approach 2: estimate probability of N concurrent requests*
Each user uses 600s of server time per day.
So the probability to be serving one given user at any given instant of one day seems to be *600/86,400 = approx 0.007*
The probability to be serving N given users at any given instant is therefore 0.007 pow N.
As we don't care about which specific N users are served, the probability to be serving whatever N users is therefore: *(0.007 pow N)xC(1000,N)* where C(1000,N) is the binomial coefficient for subsets of N elements among 1000.
For N=7 it gives a probability of approx 151%
For N=10 it gives a mighty 68%
You have to wait above N=20 to fall under a 1% probability
*3) Approach 3: estimate probability of "not N" concurrent requests*
Each user uses 600s of server time per day.
So the probability to not serve one given user at any given instant of one day seems to be *85,800/86,400 = approx 0.993*
The probability to not serve N given users at any given instant is therefore *0.993 pow N* .
This probability is interesting for big values of N (the probability to serve m users = probability to not serve N=1000-m users), which for N=993 gives 0.09%
But if I multiply by the binomial coefficient, the value is much above 1 for almost all values of N (interestingly, N=999 gives 95%, and N=1000 (0 user served) is 0.09%, but these results are probably artifacts of the floating point computations).
What mixes me up are the following questions:
Q1) Is approach 1 reasonable enough?
It seems to be modelling a degenerate form of approach 2, where the requests would not be randomly spread over the day, but optimally organized in queues.
I cannot force this usage pattern.
Q2) How would you approach this estimation? Do you have a better approach?
Q3) Obviously the formula in approach 2 is wrong at some point as for certain values of N it is above 1.
It is expected that the probability for these values of N is 1, as the linear formula prooves that it is not possible to fit all 40000 requests into one day under a concurrency level of 7. But >1 is mathematically incorrect, so what is the flaw in the reasoning, that leads to this formula?
Q4) What worries me in approach 2 is that I actually use approach 1 to compute the basic probability of 0.007, then use this result in the supposedly more general formula. I'm not sure whether the computing of the 0.007 qualifies as a deduction or as an assumption?
Q5) What's wrong with approach 3 (probability to not serve N clients)? Why are the results inconsistent with approach 2?
Q6) What worries me too is that I based all three approaches on instants of duration zero ("the probability that at any instant..."). Should I instead try to compute "the probability that over a period of 1 second, one user issues a request"? How does this modify the reasoning and the formulaes?
Thank you in advance for your help.

When it becomes difficult to get closed form solutions then resort to simulation. The following is a basic event simulation of 1 days of your problem as I understand it but using a uniform random active period. It will be trivial to change the active distribution to match your exact requirement. You will need to add JFreeChart to the classpath to run it.
One advantage of this form of simulation is that one can easily add logic such as that to throttle the response and then examine how this affects users.

Is it possible to bypass stages defined in Concurrent Request Set

Hi,
I have a concurrent request stages where there are multiple stages defined(corresponds same concurrent program with different parameter values) and this request is called from backend.
The way the stages are presently defined is on success,error & warning it will go to the next stage (e.g stage1 -> stage 2 -> stage3).
Now I have a requirement where based upon some condition, I would receive parameter values for stages. E.g I would received parameter for stage 1 to run and stage 3 to run and no parameter for stage2. In this case what I want is in the request set, stage 1 program will run and then stage 3 program will run bypassing the stage2 program as no parameter value received for stage 2 program.
Will there be any change required in the way the the link stages are defined or if there is any other way to accomplish the same.
Ultimate aim is that all the required stages(1,2,3......and so on w) will be defined but based upon the parameter value availability, corresponding stages will run like 1 then 3 then 5 and request set should complete.
I am assuming that its possible so I a trying for some workaround within PLSQL itself. Appreciate if any one can throw some light on this if clearing only the link stages could be a solution.
Regards,
Ad

What version of the DB are you running?
Here is a PL/SQL example: http://www.oracle-base.com/articles/misc/xml-over-http.php
You could also do it in Java: http://www.oracle.com/technetwork/developer-tools/jdev/dbcalloutws-howto-084195.html

Change Parameters on Scheduled request

Hi,
Is there a way, maybe profile setting, to go back into one of your scheduled reports from the concurrent manager and modify the parameters?
Thanks,
Ken

Hi,
Let me clarify a little bit.
I have a concurrent request that runs for example every Sunday. Now this request is already scheduled and running fine. Now what I want to do is go back into the already scheduled request and change a value in one of the parameters.
What happens now is I find my scheduled request click on the 'View Details' button and then click in the Parameters field. All the parameters are grayed out and I cannot change them.
Hope this explanation helps a bit.

Error after viewing Concurrent Request logfile--tools-Copy file

Hi ALL,
Navigation Path
==============
After concurrent request gets complete--View Log-tools -copy Logfile-
I am getting error "The Applications File Server could not open the file for read".
Can you please put some light on this error.
Your help is highly appreciated.
Cheers,
Sridhar

Hi,
What is the application release?
Has this ever worked? If yes, any changes have been done recently?
Can you reproduce the issue with all reported?
Please make sure that the application listener is up. Also, run AutoConfig and make sure it completes successfully.

Hussein

Submit concurrent request for cost transaction workers

Is it possible to submit a concurrent request to run one of the cost transaction workers using submit_request
Resource Cost Worker (CMCCTW)
Overhead Cost Worker (CMCOCW)
these are normally submitted by Cost Manager (CMCTCM)

By modifying the concurrent program for "Overhead Cost Worker". Set SRS on. Added the parameters it uses (group_id, transaction_type, Org_id) I was able to run the concurrent request successfully from Submit Request Form. It still gets an error when you try to submit it using submit_request. I'm more courious thqan anything at this point. I'm sure Oracle would not be happy for me to make these sorts of changes to a production system.

Need to retrive the name-value pair of concurrent request

Hello All,
I need to write a query that takes the concurrent request ID (executed concurrent request) as input and retrives the concurrent request parameter names and the values submitted to run that request.
we have considered the following tables to acheive the result:
fnd_descr_flex_col_usage_tl
fnd_concurrent_requests
fnd_concurrent_programs
however unable to map the parameter name-value pairs properly.
Thanks
Krrish

declangallagher .. I am sorry for not being very clear ...
I am sorry for taking your time.But I appreciate your effort .and time ..
I
I have two servlets 1. result (existing) 2. preResult ( probable wrap around)
The servlet
1.result : takes in the Name and gets the result from the db ( Actually uses Castor and JDO ) to get the result
and the GET is as follows
http://128.173.99.68:8080/WebApplication/result?queryFor=Experiment&Name="john"
where "queryFor" is for the name of the form and Name is the text in the VTL ( View)
2.preResult is supposed to be a wrapper around the servlet "result" this takes in the ID from the user
and is of the form
http://128.173.99.68:8080/WebApplication/preResult?queryFor=Wrapper&ID="1234"
There exists a DB mapping to ID and Name .
So Instead of calling the result servlet ..I'll directly call the preResult servlet ...get the ID from the user ...
and get the corresponding Name from the db
....here
I wish to (If possible) tweak the "request" parameter
change
1.The queryFor value to Experiment
2. add The Name="john"
and send this to the result servlet so that it process it ...........

Concurrent Request report with XML Publisher

I have Concurrent program (report) which I modified to work with XML Publisher. I change the output format to XML at the concurrent program page. Then I create the data defenition and template at XML Publisher administrator. Then I uploaded and assign the RTF template as the default template for this concurrent program.
Now I can run this report and get the output in XML report publisher .
But when I am running directly as concurrent request , I dont get any output. What am I doing wrong?
**Please Help*George Thomas*
I posted initially at a wrong place and I am re-posting here. my apology
