Long Running Interface

What is the best way to tell if an interface is processing, not locked, and is running. We have one that could run for hours.
What transactions are useful for this?
Thank-You

With SM50, you can see if tables are being read.

Long Running Reports

I'm now writing some reports that are slow running. I've tuned the sql, however because the volume of data being returned and the complexity of the report queries the reports will likely never run faster then ~30 seconds.
I'm using the ApEx advanced reporting (BIP) and ApEx version 3.0.1.
What are some thoughts on how to best implement long running reports?
Thanks,
Todd

Hi Dimitri,
You asked...
What happens when you run the report directly from BI
Publisher?There are several reports from one application. I've run the report queries in OEM SQL Tuning Advisor and tuned them.
I have not seen a noticeable difference in run times between submitting the reports from APEX or running them from BIP. The queries for these reports have the same run time when run through SQL Developer.
The slow run time of the report queries can be traced to poor table design. The application is a bit of legacy application with the front end now being rewritten using APEX. The poor table design issues are magnified by the volume of data. I have plans to partition one of the transaction tables.
Prior to rewriting the user interface in APEX the application was written in Oracle Forms. When written in Forms the application was a bolt-on to the Oracle applications. In that environment users could submit reports to the run in the background (via Concurrent Manger) then the report output was viewed later following the completion of the report.
I'm pursuing a similar solution as the concurrent manager in Oracle applications but available in the APEX, BIP environment. The reports do run between 30 seconds to 1 minute which is to long for the users to wait on the submitting page. Any thoughts on how it is possible to run these long running reports without tying up the user’s page?
I'll investigate dbms_scheduler and BIP APIs. I know BIP also has a scheduler available but I do not know much about it.
Thanks,
Todd

How to avoid long user interface response time in long measurements ?

Hi
I tried to find more information regarding techniques how to avoid long user interface response times in case of extremely long measurement times with an external instrument communicating over GPIB, so I post this hoping to get some hint or a link to a guideline. I guess this is quite normal problem.
Problem is that when I want to measure long time in order to get an average result from the instrument, I have to wait until the result is returned from the instrument. Obviously that makes the user interface response very slow in traditional technique.
My restriction is the old GPIB 488 instrument driver that I would not want to modify, but I have source code to it.
What would be the best way to improve the response time for user interface ? I have looked into the few things:
* multithreading
* callback in main program for GPIB events
* modifying instrument driver e.g. to support VISA and creating a VISA callback
regards,
Petri

Several ways to do this:
If you're getting several measurements, you could have the instrument generate an asynchronous interrupt (an "SRQ" in GPIB terms), then collect the data in response to the SRQ callback. While you're waiting for the SRQ's, you can have your main thread running the interface so responsive GUI. You don't have to spinlock on the GPIB read waiting for instrument data.
Or, as you mentioned, you could spawn a thread to manage the measurements, and use a timer in the main thread to periodically allow you to check the status of the measurement thread. Again, the main thread mostly just runs the user interface.
Either way, the idea is to keep the main thread freed up most of the time to run the GUI, and have it periodically check for completion of your measurement sequence. While you're waiting in the main thread, you may want to make sure the user can't inadvertently re-trigger another measurement sequence until the active one is complete.
If you do find yourself doing a dead wait, you'd want to break this up into a series of shorter waits, and in between each wait, do a ProcessSystemEvents from the main thread to keep the GUI active.

Long Running SQL and ORDS Spawns Multiple Database Sessions

Hi all.
We have a strange situation when accessing a long running SQL Report (a single APEX Page).
The SQL takes about 15 mins to run but when I monitor what database sessions are spawned by the APEX Listener, I see multiple sessions all executing the same SQL. It appears that after 6 minutes, the APEX Listener spawns a new database session to execute the same SQL.
Has anyone seen this before and if so, is there a key setting I am missing as I don't want this to happen. I am new to the APEX Listener and WebLogic so apologies if this is the way it's meant to work but it seems odd that after a certain amount of time (6 minutes in my case) a new database session is spawned to do the same work.
We are running:
WebLogic: 10.3.0.6
APEX_LISTENER_VERSION 2.0.0.354.17.06
Datadate: 11.2.0.3.0 Production
APEX: 4.2.1.00.08
Cheers for any help.
Duncs

Hi Duncan,
With all respect, you should please rethink your interface. I would never consider writing a Web application with a request that knowingly takes 15 minutes to return the results. You can consider doing this asynchronously via DBMS_SCHEDULER and then alerting the user (via email, perhaps) that their results are ready. Or if you can precompute this in advance, consider using materialized views so that the user's response time is sub-second.
In an era where the patience of the average end-user is measured in single-digit seconds, it is impractical to ever expect an end-user to wait 15 minutes for their resultant Web page.

Checking for status of a long-running BPEL process

Hi experts,
I have one BPEL process for originating customers' loan which usually involves various steps which takes around 15-20 mins to complete per instance. I would like to implement a user interface that can check the process's progress and display how it is going to the user.
I have thought of using an asynchronous process that updates a global variable listing status of each step inside the process and use a poller to invoke another operation (like "checkStatus" operation) of this process to retrieve this variable and display the value to the users. It may be achieved by using "OnEvent" activity waiting for "checkStatus" operation. It will run in parallel with the main process, have access to the global variable and reply this variable immediately to the caller.
It sounds like an idea in theory but invoking a web service operation for polling status is very heavy-weight and may impact performance during high-load.
I am just wondering if there is other solution to this problem as I believe the status checking is a very common expected requirement in long-running BPEL process. What might be the best practice to implement this?
Look forward to your responses.
Thanks and regards,

Hi.
I apologize for the slow reply. I am just back from overseas and did not have chance to go to the forum!
Thank you a lot for your responses!
The BAM looks like a suggested out-of-the-box solution. But it ties too much to Oracle API and will be hard to customise the way you want to interpret the status to end-users. If you want to display the process status with BAM in a web application interface, ADF is the only solution (please correct me if I am wrong). I would prefer a stand-alone, free of proprietary API solution so that we can build a screen that is technology-independent. As ADF UI is not our only supported view technology. For example, a PHP web client should be able to interpret the BPEL process status.
Will really appreciate your suggested solution.
Thanks and regards,

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.

Matt,
A namesake of yours is my client for this issue.
Coming to the problem, the customer says there is proxy configured between HTTP server and WebSphere. This proxy server times out for long running reports. If the HTTPServer is bypassed, things work fine.
A colleague of mine opened a case with BOBJ. I can get you the case# if you need it. We got this reply:
From: Takano, Hitomi

Hi Matt,
I was away for the last two days, so I couldn't reply to you sooner.
Extending the timeout setting from Webi and Infoview in BOXI R2 will not
make the long running reports work as your proxy setting at the lower
layer than BOXI just allows 5 minutes and after that the connection will
be cancelled by the proxy. I'm not sure why this setting was effective
for https only or timeout out after 2 min. This is out of scope of BOXI
R2 and your network admin would be the best person to handle. You were
getting 502 error in Java Report Panel. I googled with "502 error and
ProxyTimeout", and I got the some articles returned which say when
backend doesn't answer on requests(because it timed out), it returns to
a client an error 502.
I'll close this thread as the n/w admin at the client are working things out.
Thanks for your support.

1st gen iPod Touch, old app no longer runs

I have a first generation iPod Touch, version 3.1.3. About a year ago I bought an app, "Converter Plus (Universal)", and it worked fine until recently when I received notice of an update. There were a few app updates and all loaded successfully except the Converter Plus (Universal) which gave me an error message that the software I have does not support the updated app. I understand and accept that my old iPod Touch does not support most (almost all) new apps. The problem, however, is that the old Converter Plus (Universal) app that worked fine for a year no longer runs. I try to open it, the initial screen pops up but shuts down right away. I can only assume that when the recent update was attempted but failed it somehow messed up the old app. Is there any way to restore the old version of the app so I can go back to using it? The app only cost $1.99 so it is hardly the end of the world if I cannot use it any more, but I am worried all my other older apps (some of which receive regular updates) might also stop working and that just seems wrong to me. Feels like I am being robbed. Thanks for any suggestions.

Try:
- Reset the iPod. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Try deleting the version of that app that is in your iTunes library. Then do the following:
iTunes Store: Transferring purchases from your iOS device or iPod to a computer
Then delete the app from your iPod and sync the app back to your iPod and see if it works.
- Next try restoring from backup. Make sure that all the apps that are compatible with 3.1.3 are in your iTunes library so they can be synced back as part of the restore from backup.
- Last, restore to factory settings/new iPod and sync your media to the iPod.

We have two users that have been using Creative Cloud for almost a year. Recently, sometime in the last 4ish weeks, the users can no longer run Creative Cloud apps. (Yes, our subscription is paid.) Error simply says administrator access is required

We have two users that have been using Creative Cloud for almost a year. Recently, sometime in the last 4ish weeks, the users can no longer run Creative Cloud apps. (Yes, our subscription is paid.) Error simply says administrator access is required to install. The apps have already been installed. The users cannot run them unless they are in the local admin group.Using "Run as admin" does not work. It gives the same error.
I have opened a case with adobe support and was basically told to suck it up and put the users in the admin group. Actually, what was said was that it is "mandated that the users have administrative rights".
There are a couple of things wrong with this. It was working for both users until recently - a recent required creative cloud update. The users have never been local admins yet the apps were working (poorly, but working).
We are in an enterprise environment and users simply do not have administrative rights on the computers.
I have changed permissions on all adobe folders, granting users or authenticated users modify or full control rights, did the same in whatever Adobe registry HKLM keys I could find. Nothing has allowed the users to run the apps - unless they are put in the local admin group.
Someone has to have a fix for this. Adobe apps have proved to have far too many vunerabilities to even entertain the idea of elevating user rights. I can't imagine that enterprise environments are allowing this.
Any help or suggestions are greatly appreciated.

Jeff,
Thank you for your response. The users in question are "standard" domain users. We do not reduce users permissions below the standard level.
The apps do not load with their current standard user permissions.
The thing that makes this odd, is that up until recently they did this issue with cloud apps. The only way I can make it work for them now is to put them in the local administrator group on their pc's - which is not going to happen.
This is what they now see. As I said before, this was not a problem up until recently they would see all their available apps. If I put them in the local admin group the apps are listed without having to install. Everything is there, just not accessible to the user.

Hi Jon,
 
 
You can set the maxConnections which represents the Maximum number of connections in the pool in oc4j-ra.xml.

Long running threads (Jasper Reports) and AM-Pooling

Hi,
we are developing quite large application with ADF an BC. We have quite a lot of reports generated through Jasper that take quite long time to complete. The result is a PDF document that user gets on the UI so he can download it over download link. Reports that take over an hour to finish are never completed and returned to the user on UI. I think the problem is in AM-Polling because we are using default AM-Polling settings:
<AM-Pooling jbo.ampool.maxinactiveage="600000" jbo.ampool.monitorsleepinterval="600000" jbo.ampool.timetolive="3600000"/>
The AM is destroyed or returned to pool before reports finishes. How to properly configure those settings that even long running threads will do there jobs to the end.
We also modified web.xml as follows:
<session-config>
<session-timeout>300</session-timeout>
</session-config>
Any help appreciated.
Regards, Tadej

Your problem is not related to ADF ApplicationModules. AMs are returned to the pool no earlier than the end of request, so for sure they are not destroyed by the framework while the report is running. The AM timeout settings you are referring to are applicable only to idle AMs in the pool but not to AMs that have been checked out and used by some active request.
If you are using MS Internet Explorer, then most probably your problem is related to the IE's ReceiveTimeout setting, which defines a timeout for receiving a response from the server. I have had such problems with long running requests (involving DB processing running for more than 1 hour) and solved my problem by increasing this timeout. By default this timeout is as follows:
IE4 - 5 minutes
IE5, 6, 7, 8 - 60 minutes
I cannot find what the default value is for IE9 and IE10, but some people claim it is only 10 seconds, although this information does not sound reasonable and reliable! Anyway, the real value is hardly greater than 60 minutes.
You should increase the ReceiveTimeout registry value to an appropriate value (greater than the time necessary for your report to complete). Follow the instructions of MS Support here:
Internet Explorer error "connection timed out" when server does not respond
I have searched Internet for similar timeout settings for Google Chrome and Mozilla Firefox, but I have not found anything, so I instructed my customers (who execute long-running DB processing) to configure and use IE for these requests.

Web.Show_Document does not work with long running reports

I am using Web.Show_Document() to call reports from Forms. Everything works fine for smaller reports. However for long running reports I do not get the output instead get the page "This page cannot be displayed.". On checking the job status on the report server I find that report is still running and completes after some time but by that time my http request has already timed out. What configuration do I have to change to make my long running reports work.
Thanks

So, looks like this is an IE issue. I need to add the form server site to my list of Trusted Sites. Once I did that, everything started to work fine. Thought I'd share in case anyone is really interested.....

Script to kill long running reports in OBIEE

Hi
I have requirement to kill long running reports . I am using OBIEE version 10.1.3.4.0 which has a bug where it is not taking query limits governor and the reports are not getting killed if i am setting that parameter in RPD.
Oracle support has advised me to upgrade to next version, but for now, i cannot upgrade.
Can anyone suggest me script to run on obiee app server that can kill long running reports on obiee and database server.
I have AIX server and all reports run on database with same functional ID that is being used for ETL as well to Analytics database.

Long running reports using java servlets

Hello,
I'm running into a problem using java servlets to produce database reports and sending them back to the client browser as excel or html. The problem comes into play when the user has submitted two reports then goes to run a third and the browser hangs. I realized now that this is because of the two active connections that the user already has to the app server. Does anyone have any suggestions on how to get around this? I'm trying to now write the report to the server, and provide the browser with a url, but it seams as though the connection isn't totally closed even though I close the response printwriter.... Any suggestions would be greatly appreciated....

Unfortunately I dont have an answer to your question, but:
If the reports are large/long running, should they be generated on demand? You could schedule the reports to be generated every day, month or whenever appropriate, stored on the server and then quickly pulled by the user whenever needed.

Long running reports end successfully - present s "page can not be found"

Long running reports and browser timeouts - page can not be found"
We are launching Oracle 9i Reports from a Portal 9ias (release 9.0.2.2) system. We are in production with about 100 users. It is not going well with respect to Report problems.
We have the following problems:
1) hanging reports,
2) reports where parameter screens will not present due to large LOV on parameter screen,
3) and the most aggravating problem is "Page can not be found" presented to user when in fact the report ran successfully and create a .pdf.
We are at our wits end with Oracle Support and the Oracle Portal and Reports product.
As I said, I am launching Oracle Reports 9i from a Portal 9.0.2.2 application. I have several long running reports that complete successfully but return to the user an error "Page can not be found". Meta-link Note: 189454.1 suggests a modification to ReceiveTimeout parameter in the pc registry. We set the ReceiveTimeout parameter to 7200000. This did not solve the problem. Users still receive "Page can not be found".
Is there a report server side setting that we must set also ... or some other setting we should check?
I need to solve this issue. Is there someone out there that can help? Are there other people having similar Oracle Reports issues? According to Oracle Support we are the only people with these issues. Are we?

1) If you can reproduce the Reports Hanging issue consistently you can push Oracle Support to file a bug.
2) I am not sure about this now, but again you can take this to Oracle Support and push for resolution.
3) There are some problems with IE - Adobe integration. This is not a Reports bug. You can try
(a) Switching off Adobe - web integration in Adobe Acrobat reader settings, so that Adobe will not automatically open pdf file in web. Instead a dialog will be shown as to which application to open the pdf file or save it to disk and user can save the file to disk and open.
(b) Use IE latest version. (or some other browser like Netscape )
[ You can roll back the ReceiveTimeout param change you made to see the impacts one at a time ]
1) To confirm that this is a Adobe - IE pdf problem run the same report to htmlcss, rtf. If these come fine, then we can ascertain that this is Adobe - IE issue.
2) Give http://host:port/reports/rwservlet/showjobs?server=server_name. You can see all the jobs and their jobids. For the concerned jobs you can click and see whether output is actually generated or not.
