BEA-000449 Closing socket as no data read from it

This error message is filling up the server log files. It looks like some network problem. How can I find the cause ? This does not create a functional problem, but I am sure there will be a performance problem. Also, since this message is filling up the logs rapidly, I cannot see my regular application debug statements.

I have follow the following step
If you want to follow this solution. Go to Admin console -> Click on Domain->Configuration->Log Filters->create new Log filter.
I added this line in expression "(MESSAGE !='Closing socket as no data read from it during the configured idle timeout of 5 secs')"
Go to your server-(for each server you have to set it individually)->Logging->Advanced->Select this log filter for Standard Out or log file.
this is not working in weblogic 11G, any one have the solution to stop this msg.

Hi Amar,
I think you have given the wrong string in the filter, you are getting "*Closing socket as no data read from it on 95.66.7.15:58,089 during the configured idle timeout of 25 secs*" and you have given in the filter "*Closing socket as no data read from it during the configured idle timeout of 5 secs*".
You can change it and see if that works for you.
Also the above option is just to suppress the issue which are getting which in this case is fine as its just a warning message, however you can even try to tune few of the follwoing parameters that too would help you to remove this warning message.
1. Set the parameter -Dweblogic.client.socket.ConnectTimeout=XXX, in the start-up script of the server which you are seeing this issue under JAVA_OPTIONS
Note: Where "XXX" is the value in ms.
Example:
-Dweblogic.client.socket.ConnectTimeout=500
2. Try tuning the duration time to a higher value from the below Console path
Server -> Protocols (tab) -> HTTP (sub-tab) -> Duration

Windows7 64-bit causes BEA-000449 Closing socket as no data read

Hi,
I have a new Windows7 64-bit laptop and copied my ADF and other FMW apps to the new laptop from my windows XP. I am using Jdev 11.1.1.5 on the prior XP and the new Windows7.
The applications ran fine in XP and I am able to run the the JSPX pages in the windows7 but for one critical issue.
I have a page that issues a query to a web service and is able to display the results in a table. The table rows have links to call a managed bean to prepare then uses an Action to display the results in a new form page. The two pages are in an unbounded task flow. When I click on the link I don't see any debug messages from the bean and don't see the Form page but I see in the logs:
<Warning> <Socket> <BEA-000449> <Closing socket as no data read from it on 127.0.0.1:49,319 during the configured idle timeout of 5 secs>
I never had such issue with XP. (note I used the same Jdev 11.1.1.5 software for both)
Also I have the same application running on a Linx server and when I tested to click on the link from the result table also I never see the Form page when using Windows7 but works fine with XP !?
Can we use Windows 7 with ADF and WebCenter applications? This critical since my client users are planning to upgrade to Windows7.
Is there a special configurations to resolve such issue and others that I still didn't test.
Thanks

Update,
I was using IE 9 on windows7 and IE 8 on XP. I now tested with Firefox 64-bit, which is named Namoroka since that was the 64-bit version I found, and I didn't have such issue, surpised.
My client must use IE since we also have Siebel which uses ActiveX and many government agencies are certified on IE.
(Note: when using Namoroka, I keep getting a popup when move from one page to another that: "You are using an unsupported browser. The supported browsers are Interner Explorer 7 and higher, Firefox 2.0.0.2 and higher, Safari 3.1.2 and higher, and Google Chrome 1.0 or higher. )
From what I see now can't upgrade to windows7, but I did see that many are using it. So please help in what you already solved this issue.
Thanks

Closing socket as no data read

Hi,
I am using weblogic 10.3 application server. I am frequently facing the below warning in log file
<BEA-000449> <Closing socket as no data read from it during the configured idle timeout of *0 secs*>
As a response, "Page cannot be displayed" error is seen in browser for that request. I checked the config.xml, nowhere it is configured as 0 seconds.
Please help me with your suggestions.

CTRL-M (^M) characters in data read from sockets

Hi,
We have developed a software applications which opens upto 300 TCP connections and 4000 UDP sockets. The data from the TCP application is multiplexed to UDP sockets and viceversa.
We connect to the application using a TCP socket and send certain data to the application which in turns sends this data to all the 4000 UDP sockets. The data received from 4000 UDP sockets is in turn sent back to the TCP socket as responses.
We used telnet to connecct to thespecific TCP port on our application, sent a request to be sent to all 4000 UDP sockets and noticed ctrl-M characters in the data received from TCP socket. However we are sure we are not appending or adding this ctrl-m character while sending the data on TCP socket.
telnet host port >/tmp/abc
send a request
send next request
(after 10 mins, close connection)
cat -vet /tmp/abc >/tmp/xyz
There are ctrl-m characters in /tmp/xyz.
^M is observed only at the end of few lines and not on all lines. Successive repeatition of this test generates ^M in different lines but at the end of the line always.
Can anybody help me to know why these ^M characters are getting generated?
Note: We are completely working on Solaris and do not move contents across Windows and Unix. Our application is completely written on C++
Thanks.

I think I've misunderstood something here. The problem you're having is with the response being filtered by Telnet or your client, not what telnet is sending to the server?
In that case I think the explanation is clear. Telnet is trying to display what comes back on a screen, and it is deleting and inserting newlines every now and then according to its internal whim so as to make the data wrap. I don't know if you can control that, but I also don't know if it matters as long as you have your own client application. You just have to stop treating Telnet as a viable test client.

Data read from undo

hi,
how to find the data read from undo tablespace.
how to find the data read from datafile.
any select statement read from redo log or not. i think no,is it correct

What does it mean by "how to find data read" ?
that means how to find the a select statement whether read from data buffer cache or data file*
even if it is read from data file.first kept in buffer then return to userYes , data is always going to be read from teh buffer cache only , even if its going to be a physical read too.
In case you want to see that there was a PIO involved or logical IO( from teh cache), you can check so by seeing the stats for the query like below

Excel data read from users and upload in to Oracle DB using custom webpart

Hi Team,
I need to get the excel date from user using file upload control and read the data from the excel using custom webpart and validate the each rows whether having the values or not and need to upload the data to the oracle database.
Can you please let me know the best approach to read the data from excel using sharepoint custom webpart.
Thanks,
Mylsamy

Hi,
According to your post, my understanding is that you want to read excel data from the uploaded file and insert the data into Oracle Database.
The following way for your reference:
1.Create a Visual Web Part using Visual Studio.
2. Add an asp.net upload control into the .ascx file.
<div>
<asp:FileUpload ID="fileupload" runat="server" />
<asp:Button ID="btnUpload" runat="server" onclick="btnUpload_Click" Text="Upload" />
</div>
3. Add some logic methods into .ascx.cs file.
protected void btnUpload_Click(object sender, EventArgs e)
//read data and insert the data into Oracle database.
4.We can create a web service for adding data to Oracle database, then consume this web service in the visual web part.

Data read from text file(notepad) not enterd into particular field

Hi frends, I have used function "F4_FILENAME" and "GUI_UPLOAD" to upload a text file in notepad on my desktop to an internal table in SAP.after that i used the folowing code line to copy data from one table to other:
" insert tab2 from table itab accepting duplicate keys. "
But my problem is that in tab2 i have total 5 fields.In notepad file i have written following two words:
achal
mehra
now when i copy the data from itab to tab2 , it shows word "achal" in the field 1 of 1st row and "mehra" in field 1 of 2nd row only.
what i want is to store "a" in field1 "c" in field2 and so on in row 1.
similarly "m" in the second row and field1.
PLZ guide me.I am new to ABAP.

thnx frend but dear ur code has syntax error.Actually I am new to ABAP. I am using following code as a part of my program :

Caching data read from database

I have a big performace problem in our J2EE application. We use jsp and servlets to process a request. Servlet gets the results from database which are stored in a vector of dataobjects and vector is stored in session. We display only 20 rows in jsp and provide page navigation to view more data by Next and Prev links. The problem is we want to store results in request object instead of session variable but then that data is not availabe for Next and Prev links. We don't want to do another search to view more data. Is there a way to cache the data so that while view more data by page navigation we don't need to hit database since request object would be cleared at that time. I am clueless. I hope I explained the problem properly. Any help on this would be highly appreciated

You're not clueless, you said it yourself.
To make info available over multiple requests, you need to use a session variable rather than the request.

Data read from Memory use - ranked list

Dear Experts,
I am trying to read data from memory use -ranked list.
In general we use function pool to read the data but in case if we should read the data from a class can we do it.
{O:267}-IF_PT_HRS_D_IF~IM_CONTRACT_TES[1]-TES
in the above class in TES table we have data , we have to read data from TES .
In memory use ranked list it is like below
{O:451*\CLASS=CL_PT_HRS_IF}
Object
Regards,
Kartheek.

This one is really tricky. Display value just shows the rank but it would hold the actual value when you try to do calculations.
We have had similar problem but it was not related to ranking.
One Simple approach could be
Make them use Wrokbooks and do this calculation by using a SUM formula in Excel. Excel will consider whta is being displayed as a value for that cell
One far complicated solution is you can use the Olympic ranks and Do your sum in a Macro.
What I mean is if you get the last rank to be 10 then you can write your program to do the sum as
1098765432+1.
This approach could be taken only if they are OK with Olympic ranking.

Data read from AI buffer missing samples at start

I'm using a USB-6251. The program sets up two AI channels (reading I and Q) on a single task and a DO channel on another task. The DO channel uses the ai\SampleClock as it's clock, so the two are synchronized. The DO creates a periodic rising edge digital pulse (a clock, basically) that is used as a trigger on an external function generator. The signal from the function generator, after passing through some external signal processing hardware, is eventually what is read in by the AI channel.
We know from scoping the relevant signals, that they appear to be synchronized correctly. That is to say, the analog signal to be read arrives at the AI channel of the DAQ more or less instananeously with the DO trigger being activated. If there is a delay, it is on the order of a few microseconds.
However, when I read in the AI buffer (FiniteSamples in a repeated fashion), the waveform I get back always has a section of samples at the start that appear to be backfilled from the first actually read data-point (see the attached image). This delay is on the order of milliseconds (it varies with each run).
I want to eliminate this delay entirely. The signal should be a sinusoid that starts at sample 0 and is continuous through until the last sample read.
I have put the code below.
Setup:
// Create the analog read task
analogReadTask = new Task("analogReadTask");
// Create the virtual channel for the I component
analogReadTask.AIChannels.CreateVoltageChannel(initParams.AddrI.ChannelAddress, "I", AITerminalConfiguration.Differential, -4, 4, AIVoltageUnits.Volts);
// Create the virtual channel for the Q component
analogReadTask.AIChannels.CreateVoltageChannel(initParams.AddrQ.ChannelAddress, "Q", AITerminalConfiguration.Differential, -4, 4, AIVoltageUnits.Volts);
// Configure the clock for the analog reads
analogReadTask.Timing.ConfigureSampleClock(string.Empty, initParams.SamplingRateHz, SampleClockActiveEdge.Rising, SampleQuantityMode.FiniteSamples, totalSamples);
// Create the mult-channel reader
analogReader = new AnalogMultiChannelReader(analogReadTask.Stream);
analogReader.SynchronizeCallbacks = false;
pulseWriterTask = new Task("pulseWriterTask");
// Create a digital output channel that provides the trigger to the U/S system
pulseWriterTask.DOChannels.CreateChannel(initParams.AddrUsTrigger.PortLineAddress, "US trigger", ChannelLineGrouping.OneChannelForEachLine);
pulseWriterTask.Timing.ConfigureSampleClock("/Dev1/ai/SampleClock", initParams.SamplingRateHz, SampleClockActiveEdge.Rising, SampleQuantityMode.ContinuousSamples, samplesPerPulse);
pulseWriterTask.Stream.Buffer.OutputBufferSize = samplesPerPulse;
pulseWriterTask.Stream.WriteRegenerationMode = WriteRegenerationMode.AllowRegeneration;
pulseWriter = new DigitalSingleChannelWriter(pulseWriterTask.Stream);
pulseWaveform = new DigitalWaveform(samplesPerPulse, 1, DigitalState.ForceDown);
pulseWaveform.Signals[0].States[0] = DigitalState.ForceUp;
analogReadTask.Control(TaskAction.Verify);
pulseWriterTask.Control(TaskAction.Verify);
Starting the read:
analogReadTask.Start();
// Start writing the digital pulse, however it will not begin
// until the ai/SampleClock starts, thus implicitly synchronizing the two tasks
pulseWriter.WriteWaveform(true, pulseWaveform);
analogReader.BeginReadWaveform(totalSamples, readerCallback, analogReadTask);
Result (should be a sinusoid from start to finish)
Solved!
Go to Solution.

More information. The very first read is different from subsequent reads.
On the first read, I only see 11 trigger signals, even though we expect 16 (250-sample period for 4000 samples at 40Khz).
On subsequent reads, we see 16 trigger signals as expected, but still a small delay at the beginning of the read.

How can an image be displayed by using raw data read from the serial port?

Hi there,
I am using an embedded camera to take photos. To operate it i send commands to it via the serial interface. I have received all of the image data back through the serial port and can view it as hex data in a string. The image data is 16bit colour RAW data at 160x120 resolution meaning i have 38400 bytes of data (160x120 = 19200. 19200*16 = 307200. 307200/8 = 38400). I want to be able to display this data as a picture, but cannot figure out how to do it. Can someone please point me in the right direction? i have been fiddling about with lots of the pixmap functions but no luck. Do i need to put this data in to a 2D array first?

Yes, first convert it into a 2D array of pixel values. From there you can convert it into an image to display it in a picture control.
