Long running processes using a lot of CPU

Hi all,
We have a clustered environment and on both the DB nodes there are processes that is taking a lot of CPU and runs a really long time. The load of the servers get really high and performance degrades drastically.
I've traced the processes and the module is usually a combination of the following:
icx.por.rcv.server.ReceiveItemsAM
icx.por.reqmgmt.server.ReqMgmtAM
I know it has something to do with Purchase Orders.
Can someone please give me more info on this processes and what I can do about them?
Thanks in advance.

Sockd process uses a lot of CPU time

Hi,
I'm running the Sun Java System Web Proxy Server version 4.02 on a SunFire V210 dual processor box running Solaris 10 with the default socks5.conf for testing.
Just browsing a few web pages in Firefox or IE using the socks proxy boosts CPU usage from the sockd process to a staggering 50% and stay there for several minutes.
Comparing with the old NEC reference Socks5 daemon the Sun version is really performing badly.
The system is pretty standard though I have tuned /etc/system and the tcp stack using recommendations in the proxy administration manual. All Solaris 10 patches are installed.
prstat output:
   PID USERNAME SIZE   RSS STATE PRI NICE      TIME CPU PROCESS/NLWP
24519 proxy    6664K 4384K cpu1     0   10   0:11:18 50% sockd/43Any ideas what's wrong or do I have to stick with the old NEC reference daemon?

Context when Invoking Long Running Processes

When I use a long running process to invoke another long running process, the creator of the second long running process is always "System Context Account".
Is it possible to invoke one long running process using another long running process using the context of the workspace user? The primary need here is to be able to track the process in the audit tab.

Hi gary,
Thanks for the update.
I have just tried your "Run As" approach which is also not working.
My testing scenario:
I have created two processes (a Parent and a Child)
I have enabled RunAs option with 'Invoker' for the Child process.The parent process is configured to invoke the Child internally.
I am, as a user, invoking the Parent process from Workspace. The Child process is being invoked; However, the process's creator name still shows 'System Context Account'. I do remember that this issues was exist in previous release as well ES (8.0).
Is this a bug? or am I missing something in between?
Please advise.
Thanks,
Nith

Ditto Using A Lot Of CPU? Fans Run Often

It seems to be the culprit in causing the fans to run fast since installing SL. I stop the process from the Activity Monitor but it starts back. AM shows ditto at 90% when it's running. The fans come on, I stop ditto and they slow down, later the fans come on again, I check and ditto is running again and at 90%...............

Actually resolved this. Related to unzip issue.
Attempting to unzip some files locks up the Archive Utility. Force Quitting the Archive Utility leaves ditto open and using a lot of CPU.
Therefore, I'm using The Unarchiver (as kindly suggested by someone on my unzip problem post) at least until Apple updates the Archive Utility.

In forms how to cancel long running process or query in 10g

We have application which is hosted on 10g AS. Some forms has lot of processing to be done and sometimes user wants to cancel the processing in between maybe because he wants to change some value and refire processing.
Based on the search on net 'Esc' key was used in earlier version of forms to function as User requested Cancel operation. How can same be done in 10g. Do we have to do anything in fmrweb.res for this. Is there some setting to be done in forms or in AS for this functionality.
Does this matter on whether JInitiator is used or JPI is used for running the application?
Edited by: suresh_mathew on May 21, 2013 1:36 AM

Hi,
Exit can be used to cancel query mode i.e. in case you go into query mode by Exit you can cancel query mode. Suppose you went into query mode and you have fired query which will take some time to fetch how can I abort it.
In earlier version of form there was 'Cancel' facility wherein if triggered it used to fire an error message 'Ora--01013 user requested cancel of current operation"
With this facility you can abort any query which is executing or any long running process which forms is currently performing.
fmrweb.res would have entry like
27 : 0 : "Esc" : 1001 : "Cancel"
The above entry I picked from OPN
Java Function Numbers And Key Mappings For Forms Deployed Over Web [ID 66534.1]
Unfortunately this is not working for us even if I put this in frmweb.res of 10g AS
Basically I want ability to Abort/Cancel a long running process be it query execution or standard process triggered in the form.
Any advise or help is highly appreciated.
Suresh

Long running process/query

One of my after submit processes involves a lot of processing, temp tables, sorting, aggregating, etc.
When this process is invoked from a page, is there a way to put up a generic 'Processing...' page that auto refreshes and when my back-end process is done, takes me to my results page?
Thanks

Let me see if I understand you...
So, the first page (that would have invoked the long running process) branches to the "processing page". That page has a onload that does doSubmit(). The after submit process on this processing page calls my long running process via dbms_job. When the long running process ends, the branch on the processing page takes me back to the first page (or whereever).
But then as far as the browser is concerned, the processing page never "finishes loading". IE's progress bar would creep ahead sloooowly and it would appear as if the page is loading for a looong time!
Wouldnt it be cleaner to use the META refresh tag like John was suggesting?
Also, using either of your approaches, how would I allow the user to "Cancel" the long running process and go back to the first page?
Could you please put up a quick sample of this in action on htmldb.oracle.com?
Thanks

Question : Scheduling a Long Running Process in BPEL

Hi All,
I have a doubt regarding deployment and scheduling of a Long Running Process in BPEL console like the way we schedule a concurrent program in Oracle Apps.
Business Scenario:
We have developed a BPEL process to pull data from the Database, do the required transformation and then enqueue the transformed data in a queue present in another database.
Then a Java program will pick the data from the queue and then generate an XML file and send it to FTPserver of the Trading Partners(TP's).
We have two Trading Partners and hence the generated XML will be put into the appropriate FTP servers of the TP's.
The BPEL processing for both the Trading Partners is identical. Only the generated XML is put in different FTP servers.
My question here is:
1. Since the processing is same for both the TP's, how can we use the same process for both the Trading Partners.Can we handle it in the BPEL process itself ?
2. Is there any way to schedule the same process in BPEL console, to first run for Trading Partner TP1 and wait for say 15 mins and then run for another Trading Partner TP2 and this cycle should continue since we will be deploying it in production environment and continuous updation of the transactions will be happening in the database.
So far my knowledge in BPEL goes, i could not find any way to schedule a process in BPEL console. If any one has come across similar scenario, please post your updates/approach which will help us in defining the architecture for our client.
Thanks In Advance,
Cheers
Dibya

Hi Marc,
Thanks a Lot for ur inputs.
Need some more clarification for quetsion no.1 in my previous post.
From our BPEL process we are calling a package which takes the Trading Partner name as the input and some other parameters. Our BPEL process will be run for both the Trading Partners since the processing is identical.
If we develop two different processes for both Trading Partners, then there will be locking issues in the database since both the processes will refer to the same table.
Hence we were looking for an option where we can use the same process for both the Trading Partners. Is there any way to handle it in BPEL process.
Your inputs will be really helpful.
Thanks In Advance,
Dibya

Correlating to long running process

I'm trying to set up a long running process that handles item-storage. For handling of the BPEL I have a process which needs to tell the long running process which item is stored in that particular storage. For example: i have 200 bins, which can contain up to 100 items. As the bins are handled individually (when filled), I need the 100 bpels that handle the items to wait until the long running process is finished.
So, I figured to make a BPEL that accepts 2 messages: 'initiate' and 'addItem'. Initiate sets up the bin and waits until filled before handling the bin.
The addItem is placed in a onMessage branch. This branch should be 'create Instance = no", as the instance is created when the bin is initiated. I get one initiate message and 100 addItem messages. Initiate & additem are correlated, so I should only receive the messages for this particular bin. However, when I try to compile this process, I get the following message:
Error(36): [Error ORABPEL-10050]: no create instance activity [Description]: in line 36 of "L:\workspaces\MyTests\LongRunningProcess\LongRunningProcess.bpel", There is not an activity (receive/pick) to start the process. [Potential fix]: You might want to set createInstance="yes" for this <receive> / <pick>.
Well, the 'fix' is not quite what I had in mind. I cannot have a createInstance='yes' here, as the instance is already created when I started handling the bin. Besides, I have to handle 100 incoming messages, not just 1.
I have a need for this kind of pattern, as I have a lot of converging & diverging messages in our processing. Diverging is easy, converging is giving me a lot of headaches.
Anyone has ideas how to help me find a solution for this? Thanks in advance!

Hi,
1) You could use conversation for the first issue which are designed for this usecase.
Conversations are essential for any web service involved in asynchronous communication. This includes web services that communicate with clients using callbacks or polling interfaces, and web services that use controls with callbacks.

===============================================================
Looking in the Manual Recovery screen, I can see an Activity I can recover. It's about an assign Activity where I'm doing a single boolean assignation.
Of course, together with the ORABPEL-05002 error I got also the 'Transaction was rolled back: time out' message. Note that I have modified the transaction-timeout value to 180000. The error occurs during the night, with no heavy load of the server.
Recovering the assign activity brings back the process in the running state.
My process pattern:
while (1 == 1) {
do activity;
wait_timeout();
So, I have the following questions:
1. Which is cause of this error?
2. How may I automatically recover this lost activity? RecoveryAgent?
Any suggestion is appreciated.
Regards,
amo

These are the possible cause to the problem and their solutions:
Poor performance of the dehydration database If you are using Oracle Lite as dehydration store, please switch to use Oracle 9i or 10g. If Oracle 9i/10g is already in use, check the database parameter 'process' and 'session' to make sure it can handle the expected throughput.
OC4J has too few available connections to the dehydration database. Increase the maxConnection number of the BPELServerDataSource at the BPEL_HOME/integration/orabpel/system/appserver/oc4j/j2ee/home/config/data-sources.xml (for developer edition) or IAS_HOME/j2ee/OC4J_BPEL/config/data-sources.xml (mid-tier installation).
Size of message is too big Two ways to deal with this problem:
Increase the transaction timeout at PEL_HOME/integration/orabpel/system/appserver/oc4j/j2ee/home/config/server.xml (developer edition) or IAS_HOME/j2ee/OC4J_BPEL/config/server.xml (mid-tier installation)
Decrease the auditLevel from BPELConsole -> Manage BPEL Domain -> Configurations tab. Doing so will reduce the amount of data saved to the dehydration store.

Is Photos using a lot of CPU?

Photos is now using a lot of CPU. This is after it converted my iPhoto library. Is this normal? Is anyone else seeing this on their machine? Here's a screen shot with
Photos hidden (not actively being used).

It's probably still building the library and optimizing. Mine is still way up there as well. I'm going to let it run over night and see where it's at in the morning.

ProgressIndicator and hourglass for long running processes

Hi all,
Iam using Oracle ADF 10g with EJBs.
I have a long running process for which I want to give the user an indication of its progress. The process is run upon clicking a submit button.
I have tested the use of the combination of progressIndicator + poll according to the example of Gerger consulting( http://gergerconsulting.blogspot.com/2007/04/adf-faces-progressindicator-example-for.html) but it did not work. The problem is that my long running process hangs the page and the progress bar does not work until the process has finished.
I have seen a similar post in this foum (Re: How to run long background jobs in ADF applications where a user complains that there is not an Oracle method for running asynchronous processes from Oracle ADF.
I've tested to isolate my asynchronous process with the progressIndicator + poll in a single ADF page. The process is being activated from an invokeAction from the executables of the pagedef file. But again the process hangs the page and the progressIndicator does not display at all.
So I have abandoned the idea of the progress indicator and Iam thinking of using an hourglass.
Is there an example or guidelines of how I can do it?

Thanks John for your reply,
Iam still working on the progressIndicator. I have read the discussion thoroughly quite many times.
One thing I have not yet figured out from your discussion is how you manage to create the long-running-process thread within an action method within the managed bean and make the thread still be active, while the parent action method has finished.
Usually the managed beans attached to a .jspx pages has request scope. So a commandButton's action method (that will spawn the long running thread) will finish much earlier than the thread and it will kill the thread.
Thanks,
Dimitris

GF 3.1.1 Admin Console Freeze -- A long-running process has been detected

I installed Glassfish 3.1.1 on both sparc and intel servers for solaris 10 & 11 platform. All my servers have the same symptom when I access the admin console. The console freezed and pop-up a message "A long-running process has been detected". There is nothing I can do at this point. I've tried accessing from different PC with different browsers (IE, Firefox 5, Chrome and Safari), but nothing is working including clearing the cache. Also, tried uninstall and install again (with and without updatetool) many times. Any idea how do I stop the popup message? Am I the only one has this problem? I'm using JDK 1.7 (GF 3.1.1 support JAVA 7). I need help!!!!!
Thanks,
- Johnny

The only fix I know of for this issue is to reboot the host.
If there is another fix someone please let me know as I have users who run into this often.
Thanks

Call long running process and return immediately

Hi everyone,
Here' my problem : I am calling an onDemand application process when clicking on a button. It's a very long running process; and while waiting for the response my browser stops responding (white page).
So, is there a way to call a process and return immediately to the javascript. The process will set a field to a given value when it finishes. In javascript side, I can then check in a while boucle the value of this field to know if the process has ended.But I dont know how to return just after the application process call ...
Thanks and best regards,
Othman

I presume that you can achieve that by means of a batch job.
You can use an automatic page reload every X seconds until a certain "flag" (or similar mechanism) changes state and check it in a before header process. In the meanwhile you can display some animated GIF for instance.
Once the processing is completed you remove the reload timer from the header or you branch to a different page using a programmatic technique like procedure owa_util.redirect_url.
Bye,
Flavio

HTTP Server Hangs on Long Running Process

Hi,
We are having an issue with our production environment where long running processes i.e. > 5 mins will cause the client application to stop responding. We notice that this is only affecting forms which has no activity during the busy period i.e. forms which call a back end DB procedure or function and waits for a response from the DB to say that the process is done.
Checking on the process itself from the DB shows that the process has completed successfully but somehow there's no response back to the client to say that it's completed. As a result, the client will be in busy status forever.
We are sure that the issue originates from the HTTP server because when we by-pass the HTTP server i.e. send the request directly to the Apps server, this behaviour is not happening.
By thew way, we are running on Oracle Forms 11g using Weblogic.
Changes made so far but to no effect:
maxBlockTime=1800000 (web.xml)
keepAlive=Off (httpd.conf)
Timeout=1800 (httpd.conf)
FORMS_TIMEOUT=60 (formsweb.cfg)
heartbeat=4 (formsweb.cfg)
Session-Timeout=30 (web.xml)
Can this be related to network configuration? If yes, what are the things to look for?
Thanks.

as the response came from the server your httpd service is not getting active for that you
need to keep the httpd service alive so that the response can be obeyed
just try this
keepAlive=On (httpd.conf)

Firefox 9 after a while starts using a lot of CPU power, need help!

After a while (2 hours or more) firefox 9 (not the plugin container) starts eating up more and more CPU power, usually just to 25% (because usually i close it and restart it after that), but today i had work to do and i couldn't restart it right then and that resulted in firefix using about 50-60% of a 4 core 3.2GHz CPU (AMD Phenom II X4 955).
I'm not doing anything extraordinary just writing emails and just plain normal browsing)
I only notice this because my CPU fan speeds up and makes a lot more noise if using more then 20% CPU power.
I'm pretty sure regular users wouldn't notice anything until it started to slow down their whole PC
I'm using Firefox 9.0.1 running on Win 7 64bit, i have about 20-30 tabs always open (loading) and i haven't tried disabling any add-ons.
I've read on forums that this might have something to do with flash data piling up, or with having to many tabs open.

It didn't show up when i searched for the problem on Google and it didn't show up when i search here on Firefox's support site either.
And the reason it didn't because it's mostly not about my problem.
'''If' it was one of those things then i would have a high CPU usage the minute i opened my browser, but i don't.'''
'''It will use a lot of CPU power (after a couple of hours) even if i don't do anything '''
And yes hardware acceleration is on and so is submit performance data and i use Ad Block Plus, and there isn't a correctly working theme or add-on out there that could use 50-60% of a 3.2GHz quad core CPU
I don't think this is something that can be fixed that easily
