thanks&regards

Execute the following query:
select t.request_id,
       t.actual_start_date,
       t.actual_completion_date,
       trunc((t.actual_completion_date - t.actual_start_date) * 24 * 60, 2) as "Total Time (Min)"
from fnd_concurrent_requests t
where t.actual_start_date like sysdate
   and (t.actual_completion_date - t.actual_start_date) * 24 > 1;Next time, please post oracle apps related issues here:

STRANGE Issue in submitting Concurrent Request - 11.5.10.2

Hello Gurus,
I am facing a weird issue in submitting an Oracle EBS report(.rdf file).
Below is the problem description.
[1] - When I submit the report, it goes into running mode.
[2] - It stays in running mode forever.
[3] - When we run the same report in non Production environments, report complete instantly.
[4] - Even the same report runs perfectly well from report designer.
[5] - All tuning considerations are well cleared. The same report is fetching data instantly everywhere in prod.
[6] - The STRANGE thing that we have noticed that, when we submit the concurrent request, the ORACLE_PROCESS_ID in FND_CONCURRENT_REQUEST does not get populated. It is NULL. For all other request, there is process ID.
[7] - We even recreated Concurred program but still no luck.
[8] - Bounced Database, Middle Tier but still no luck.
[9] - Redefined a new conc mgr but still no luck.I believe #6 from above is a critical lead towards the problem. Having run out of all options, I am posting it here on the forum. All Tuning aspects are well taken care. It is rock solid and tuned to death. Without taking care of Tuning, I would not have posted this.
Thanks,
R

Hussein,
You must be a one man show here :) 34,295 POSTS!!!!!!!!!! WOOOOOOOOOW.
Anyways, The link you have given, finally concludes with following
Hi All,
Got solution for this problem
I have raised SR for this
SR Analyst also told the same as (MCHARCHU)
I have added SRW.USER_EXIT('FND SRWINIT'); in before report trigger
and SRW.USER_EXIT('FND SRWEXIT'); in after report trigger
and also a parameter P_CONC_REQUEST_ID in User PARAMETERS
Thanks to all of you guys......
Thanks,
Bhanu Chander.In my report, All of above settings are already covered but still the issue is persistent.

How to submit a concurrent request from Discoverer report.

I would like to know If any one has tried submitting a concurrent request from Discoverer Report?_
This is no stupid question, but our team here finally decided with a solution to our long pending issues with few of the discoverer report. To Proceed further, we would like to know, how to submit a concurrent request from Discoverer report?
We are looking for calling a package from the Disco admin by passing the parameters from the disco to the 6i report.
All help us in this regards are much appreciated.
Kindly help us in the same!
Thanks
Arun

Thanks Rod for confirming the same.
I will be trying the same today and will let you know if I succeed in doing it.
If I can share the actual requirement with you, it goes like this.
"I will be triggering the Oracle 6i standard AP Trail balance report through the Disco report. The standard report will be inserting the required data to one of my custom table. Once the concurrent program completes normal, my custom table will be having the required data to create the workbook specific to the current run of the concurrent program.
The one problem which I think could happen is, How can I make my disco report to wait till the standard program to complete in normal so that my disco report can be generated with the data from custom table.
Will the above requirement is possible If I follow the way you mention in the PDF or Could you suggest a better way for achieving the same.
In short, my requirement is: The custom table(say XX_TABLE) will be populated with data when the standard 6i report is run and the disco admin will be making of the custom table (XX_TABLE) to generate the report.
Please advice.
Thanks
Arun

Concurrent request -one at a time

I am going to run this request from PL/SQL,
this is going to be called more than 1 time simultaniously, if more than 1 user runs the report at a time.
I want to make it run one at a time, instead of running 2 different calls at same time.
like i want to make the first request get completed and then run the next.
How do i do it?
FND_REQUEST.SUBMIT_REQUEST('BOM','BMCOIN','Import Bills and Routings',
NULL,FALSE,
org_id,'1','1','1','1');

Receive warning on Concurrent request

Hi All,
I am running the preliminary payment register while creating a payment batch but receive a warning message.
APP-FND-00500: AFPPRN received a return code of failure from routine FDUPRN. An error occurred while AOL tried to spawn the print process
Cause: AFPPRN received a return code of failure from the OSD routine FDUPRN. An error occurred while AOL tried to spawn the print process.
Please give me any suggestions to how to fix this.
Thanks in advance,

Hi,
What is the application release?
Do you get this warning with all concurrent requests or just with this specific one?
Please go through the following documents and see if it helps in resolving the issue.

i througly checked with the above 3rd Document, ever settings are very fine,, no changes in this,, then i bounced the concurrent. the notes says ths problem may occure because of insufficient of space or not proper setup of xml, !;(

XML Output from Concurrent Request DBMS_XMLGEN

I am trying to create xml output for a concurrent request, using the DBMS_XMLGEN package to generate my XML?
I have gotten so far as to be able to run my procedure and see the output in TOAD using dbms_output.put_line, but I can't seem to quite get the right link to convert this to Oracle Apps output.
I have a concurrent request setup to output XML.
This calls my procedure to return to the output file.
So far, when I run from APPS, all that shows in the Output file is 'XML document must have a top level element.'
Here is the relevant code...
ctx DBMS_XMLGEN.ctxHandle; -- vars to convert SQL output to xml
xml clob;
xmlc varchar2(4000);
off integer := 1;
len integer := 4000;
i number := 0;
rc_data sys_refcursor;
begin
-- this calls simple open cursor for sql statement, returns rows
rc_data := fa10022_data(P_BOOK_TYPE_CODE
, P_STATE
, v_BEG_DATE_EFFECTIVE
, v_END_DATE_EFFECTIVE
, P_BEG_ASSET_ACCT
, P_END_ASSET_ACCT
, v_depr_per_ctr);
ctx := dbms_xmlgen.newContext(rc_data);
dbms_xmlgen.setRowsetTag(ctx, 'XXFA10022');
dbms_xmlgen.setRowTag(ctx, 'G_DATA');
xml := dbms_xmlgen.getXml(Ctx);
i := dbms_xmlgen.getNumRowsProcessed(ctx);
dbms_xmlgen.closeContext(Ctx);
apps.fnd_file.put_line(apps.fnd_file.output, xml);
I was also following this link...
http://www.appsassociates.com/products/Generation_XML_PLSQL.pdf
any suggestions?
Thanks!!
Janel

That was painful, but it helped!
Most of it is workflow code...POXMLGEN contains the pertinent coding.
I think my problem now lies with some of my data. Depending on what is returned, I sometimes receive a warning with no output. I know there are special characters in the data (ex eacute), but I can't tell if that is what is causing the issue. I do have the statement dbms_xmlgen.setConvertSpecialChars(ctx, TRUE); in my code, so not sure what else to do.
This is what is being returned in OPP log...

ConcurrentModificationException - concurrent requests while lazy loading a relationship without server warmup

Hello,
We are running into a ConcurrentModificationException when we are firing 100 concurrent requests without warming up the server.
Looks like the error is coming up when a a relationship is being lazy loaded.
We are seeing this behavior consistently. Once the server is warmed up, we are not seeing any issues under concurrency.
I am attaching the two DAOs that are related to the issue.
ExtensionPointRulesetDAO has a M:1 relationship with RuleSetEntityDAO and we are getting the error when ExtensionPointRuleSetDAO._persistence_get_ruleSetEntity() is called.

Hi,
Found a note explaining the significance of these errors.
It says:
"NZE-28862: SSL connection failed
Cause: This error occurred because the peer closed the connection.
Action: Enable Oracle Net tracing on both sides and examine the trace output. Contact Oracle Customer support with the trace output."
For further details you may refer the Note: 244527.1 - Explanation of "SSL call to NZ function nzos_Handshake failed" error codes

Concurrent Manager Issue in Oracle Apps 11i on MS Windows 2003

Hi,
We have Oracle Apps 11i (11.5.10) on Windows 2003 running Oracle Financilas and Supply Chain.
From this morning onwards, concurrent requests are not getting completed. All requests are showing Running Normally. I checked the server (Single Node 4 GB Memory) and CPU usage is more than 90%. Task Manager is showing 50% CPU usage for SYSTEM (Image Name). Once the CPU usage for SYSTEM(image name) goes beyond 40% then the server is becoming slow and the problem starts.
When I stop the Concurrent Manager it does not stop and I have to End Process the FNDLIBR process manually.
I have recreated the concurrent manager using CCMSETUP and also ran cmclean.sql. Nothing is helping.
System is Live since 2006 and the issue started only today.
Please suggest any solutions as this is happening in our Production system.
Thanks.
Thiru

Thiru,
Which concurrent manager consumes the CPU usage? Are you able to identify it?
Any errors in the CM log file? Did you try to start the CM with diag=y and see if any errors are reported in the log files?
What happen to the CPU usage when you stop the CM?
I assume that you are running Purge Concurrent Manager/Requests on regular basis, so this should not be an issue here.
Please review the following notes, and see if it helps.

Concurrent request taking more time than usual

HI,
I am running a concurrent request : Payables transfer to general Ledger
which was usually getting completed within 5 minutes....but now it is taking hours to complete....Log file not showing any errors as such...
I increased the standard mangers processes and bounce the Concurrent managers n Database as well...i also ran cmclean.sql, but no luck..
Can anybody suggest me the approach for this problem...
thanks n regards,
Sajad

Check the enable trace option in the concurrent program definitions.
After that run the concurrent request and get the trace file in udump directory and tkprof it, and analyze which is the query that is causing the issue.

Cancelling Concurrent Request hangs

Hi Experts,
Recently we upgrade the OS to solaris 5.8 to 5.10
Concurrent request like Receipt Printing running more than 20 minutes and it completed with warning, the log file shows printer is not accepting. if we cancel these requests it hangs.
Then we will cancel this concurrent request from OS level. we are facing this issue after upgrading the OS to Solaris 5.10.
In Solaris 5.10 is there any new for printer configuration. Please help me to overcome this.
Regards
R.Sundaravel

After the OS upgrade, did you relink all of the application binaries ? Pl see MOS Doc 209810.1 (How to Relink Oracle Applications 11i Programs After Upgrade or Patch of the UNIX Operating System)

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.

HttpURLConnection returns overlaping responses for concurrent requests

Hi,
we are facing an issue in making HttpURLConnection requests. Our servlet has to make HttpURLConnection to another server (Both request and response body to be passed is xml, that is the contract with server which we are firing requests to). User can fire 2 concurrent requests one after another with out waiting for first request to be completed. When two requests are fired, two threads are executing the below block of code with no time. And the problem is first response is empty second response contains data for both responses
           URL url = new URL(urlStr);
            HttpURLConnection c = (HttpURLConnection) (url.openConnection());
            c.setRequestMethod("POST");
            c.setRequestProperty("Content-Type", "text/xml; charset=\"utf-8\"");
            c.setDoOutput(true);
            out = new BufferedOutputStream(c.getOutputStream());
            out.write(requestData.getBytes("UTF-8"));
            out.close();
            String inputLine = null;
            StringBuffer sBuffer = new StringBuffer();
            in2 = new BufferedReader(new InputStreamReader(c.getInputStream(), "UTF-8"));
            while ((inputLine = in2.readLine()) != null) {
                sBuffer.append(inputLine);
                sBuffer.append("\n");
            String responseXML = sBuffer.toString();and the above code is in separate static class. we tried using third party implementations for HttpURLConnection instead of sun implementation. NO LUCK.
Any help in resolving this issue would be of great help
Thanks,
JKChaitanya

JKChaitanya wrote:
"in2" is also local variable to the method, only "requestData" comes from servlet's doPost method, all other variables are local to the method in which HttpURLConnection code is availableIt seems to me that the implication is that the server you are chaining to is not thread safe and can only handle one request at a time. This means that you will have to process the requests sequentially. Two obvious approaches - use synchronisation or use a request queue. To test the hypothesis it would be very easy to use synchronisation on your servlet class object. Note - you cannot reliably synchronise on the servlet instance since your server may be configured to use more than one instance.
