Java.io.IOException: Connection timed out while using non-blocking NIO

Hi,
I am using non-blocking NIO on jdk 1.6 to transfer files between two processes. The problem is that the sender thread times out on the write call even though it's in non-blocking mode. It doesn't make sense. The receiver on the other end is running fine, and even tries to read from the socket after the sender drops the connection, and throws a Connection reset by peer exception. I should mention that the receiver is sometimes busy doing other stuff, and may be a second or two late in issuing the read call. But if I understand correctly, default TCP timeout is about 2 minutes, so there's no reason why it should timeout in a second or two. I'd appreciate it if anyone has any insight.
Thanks!

No I have definitely completed the connection since I it happens a while after the transfer has actually started and part of the file has already been transferred. Oh btw, I should mention that it doesn't always happen. It's intermittent. And it's not a network issue since iperf tests between the two nodes show nothing unusual.

Error SOAP: call failed: java.io.IOException: Read timed out; HTTP 200 OK

Hi PI gurus,
Need some suggestions on one issue below -
Scenario - proxy (SAP) to SOAP (Web based system)
In the RWB Communication Channel Monitirong we are receiving the below error
" Error SOAP: call failed: java.io.IOException: Read timed out; HTTP 200 OK"
the request from XI system is going to target system and printing the lables (as per the functionality) with no issues but the comminication channel is giving the above error and this is causing the repeated sending the same request to target sytem and the data is printing repeateadly. This issues is occuring in Quality environment.
Strangley the same Interface with the same connectivity details is working fine in Development environment. But not working in Quality environment. Checked the firewalls settings on both in XI and Target system side and confirmed that everything is fine.
Below are the Logs both from Quality and developement are as follows
Quality ( Failure Case)
17.03.2011 07:19:59 Success SOAP: request message entering the adapter with user J2EE_GUEST
17.03.2011 07:25:03 Error SOAP: call failed: java.io.IOException: Read timed out; HTTP 200 OK
Development (Success ful)
17.03.2011 07:27:55 Success SOAP: request message entering the adapter with user J2EE_GUEST
17.03.2011 07:27:58 Success SOAP: completed the processing
When we checked with basis team on user id J2EE_GUEST, they confirmed that they are same in Development and Quality.
I repeat,, that the same target url and everthing is same in XI Configuration
Thanks in Advance. Points would be rewared for the best solution.
Thanks,
Jitender

HI Jitender,
If your scenariois working in DEV and if it is not working in QAS.Could you please check if both the systems are at same patch levels..

Getting error connection timed out while invoking webservice from bpel.

Hi,
I am trying to call a secure webservice developed in .Net having extension .svc from the bpel service and in response i am getting error
com.oracle.bpel.client.BPELFault: faultName: {{http://schemas.oracle.com/bpel/extension}remoteFault}
messageType: {{http://schemas.oracle.com/bpel/extension}RuntimeFaultMessage}
parts: {{summary=<summary>exception on JaxRpc invoke: HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message send failed: Connection timed out: connect</summary>
I am able to call this web service from the java programme using HTTPClient by setting the username/password and soapaction in http Header but not from the BPEL process. This .Net service is synchronous in nature. I also set the proxy in opmn.xml but didn't got any success.
Please reply me ASAP. Need urgent help.
Thanks.

Are you working on 11g ? if this is 11g
How are you invoking the webservice ...does it have any authentication..
If the webservice which you are invoking has basic http authentication...
1. In the composite.xml file, right click on the reference and configure WS policies. In security tab, add a security policy named"oracle/wss_http_token_client_policy"
2. Add two binding properties for the reference
(i) oracle.webservices.auth.username
(ii) oracle.webservices.auth.password
and provide the username and password for those two properties...
Just try this out...
Thanks,

My Ipad 2 is timing out while using it. Battery is charged and all apps are closed.

My Ipad 2 is timing out while I'm using it and I can't figure out why. I've made sure that all of the apps are shut down. The screen goes blank and thepassword screen shows up a few seconds later.

Your apps aren't just crashing, or you would be taken back to the home screens and not the screen where your passcode have to be entered. Seems like something is corrupt. Have you rebooted the iPad by holding down on the sleep and home buttons at the same time until the Apple logo appears on the screen? I don't think that's likely to fix the problem but it will not hurt anything to try that first.
You can also try resetting all settings. Settings>General>Reset>Reset All Settings. You will have to enter all of your device settings again.... All of the settings in the settings app will have to be re-entered. You won't lose any data, but it takes time to enter all of the settings again.

Wget - Connection timed out when using "long" strings

I'm having a problem with a little script to change some settings for IP-phones. Here is the script:
#!/bin/bash
for i in "0" #"4"
do
for j in $(seq 176 176)
do
wget --timeout=1 --tries=1 --keep-session-cookies --save-cookies cookies.txt --post-file=postfile http://192.168.$i.$j/dologin.htm
wget --timeout=1 --tries=1 --load-cookies cookies.txt --post-file=postfile2 http://192.168.$i.$j/update.htm
done
done
postfile looks like this and is just for logging in:
P2=<pass>&
postfile2 looks like this:
P270=123456&
The problem now is, when using it like above, everything works fine. But if I make the text in postfile2 one character longer, I get this:
Connecting to 192.168.0.176:80... connected.
HTTP request sent, awaiting response... Read error (Connection timed out) in headers.
Giving up.
It doesn't matter where I put the character to make the string longer (I can for example use P32=1234567& and it works). I have tested the script from different machines and used different phones, always the same. Any ideas?

daf666 wrote:The two files look identical, are you sure that the "bad" one is actually a capture of the timed out session? (both have same data length and same value in the content-length header).
Yes, they are different and the bad is is from the timeout .
daf666 wrote:Anyway, this timeout might occur, if for some reason wget will say content length is 10 and send only 9 characters in the post request..
Any idea what I can do about it? There is something fishy going on. I did this once before a few month ago when I wanted to change other settings. I tried to do the same thing again but even this doesn't work anymore. Maybe I should just try curl .

You would need to define secondary RFC Destination. Follow these steps to the end.
1.Create a secondary RFC user and an authorization in the backend(ECC)
1a)In Transaction SU01, create a new user (on the 'Logon data' tab,
you should select user type 'Dialog' or 'Service').
1b) Call Transaction PFCG for the role maintenance and create your own
role.
1c) In the role, select the 'Authorizations' tab and and choose the
button to change the authorization.
1d) Do not select ANY template on the dialog box.
1e) Choose 'Manual' ; then enter authorization object S_RFC and confirm
the entry.
1f) Expand the authorization object and choose the pencil symbol for
the 'Name of RFC to be protected'.
1g)Choose the pencil symbol for the 'Type of RFC object to be
protected', select the 'Function group' checkbox and save the
change.
1h)Generate and save the authorizations. Then return to the role.
1i)On the 'User' tab, enter the user you have created and carry out a
user comparison.
2. Define an secodary RFC destination in SRM server with the RFC user you have created
3. Supplier Relationship Management -> SRM Server -> Technical Basic Settings -> Define Backend Systems
In the Logical system entry of your backendsytem :Enter the secondary RFC destination into RFC(Dialog) field of the
4.Also make sure that the end user(Person creating shopping cart) has authorization object M_BBP_SHLP.
Let me know if this helps.

Using non-blocking NIO, need Main Thread wait?

I'm trying to utilize the New IO libraries to create a simple url check application. The application just tests return codes to make sure the list of urls I have are still valid.
I'm using the NIO libraries because I had problems with the URLConnection object hanging when I ran into a url where the server never replied. It just sat there waiting for a reply.
Now I have a new problem, the connection to the web server is now in a new thread and I need to wait for the connection to finish before using it. I can't figure out how to make the main app wait for the connection. All of the documentation I find for the Wait() method refers to threads and I can't find how to refer to the main application thread.
Any suggestions?
Josh

Ok, this is were I have some gaps in my Java knowledge. How do I wait for OP_CONNECT to fire. Is it like setting up a ActionListener but for a non-visual object?
Also what do you mean when you refer to deregistering it?
You don't need to explain everything. I would be happy if I was just pointed at the appropriate pages and I'll do the leg work.
Josh
If you're using NIO the connection can be handled in
the same thread as the I/O. Just wait for OP_CONNECT
to fire, deregister it, and away you go.

Non-Blocking SocketChannel read give Connection timed out

Hi,
My program is using Non-Block NIO SocketChannel for both Server and Client sides. However, if the connection between server and client has been idle for a while, when the client try to communicate with server, it gets blocked for a while (15 minutes) and then receives the following exception:
java.io.IOException: Connection timed out
     at sun.nio.ch.FileDispatcher.read0(Native Method)
     at sun.nio.ch.SocketDispatcher.read(Unknown Source)
     at sun.nio.ch.IOUtil.readIntoNativeBuffer(Unknown Source)
     at sun.nio.ch.IOUtil.read(Unknown Source)
     at sun.nio.ch.SocketChannelImpl.read(Unknown Source)
How can this be since the read is in Non-Blocking mode? Also, is there anyway to determine the timeout without being blocked?

This would mean that you are trying to read from the socket without having properly completed the connection, which timed out. I would say you are connecting in non-blocking mode but not calling finishConnect() when you get OP_CONNECT.

destination address is a "+" sign followed by cell number of client in US and I am in diff country.
source code I am using is "+" sign followed by a short code given by client.
I am also not aware what short codes are for.
I am also not sure whether I am passing correct parameters.
I just followed a demo code from the api's sample file. (open market api......swsms-2.9.16 is the jar used.).
would like to know If destination address can be my cell number.
The open market people have configured the demo short code for our SMS messaging account.
This feature will allow us to test our platform to send and receive SMS messages
while we are waiting for our dedicated short code.
Mobile Originated messages MUST start with our assigned keyword(s) to be routed to you.
We have a few keywords but don't know how to use them.
Please help!
Thanks in advance.

I had a same problem.
It was definately URL and SOAP Action Problem.
Also, I didnt configure the Proxy too.
Please dont waste more time in looking inot other configs.
Just give a careful look at Target URL and SOAP Action, again and again.

Connection refused to host: connection timed out

I have been struggling with this problem a couple of days now so I really hope someone can help me. I am trying to get rmi to work in a NAT environment.
