Two Socket errors: Socket write and Socket reset

does anyone know the reasons and remedies for the error
java.net.SocketException: Software caused connection abort: socket write error
and
java.net.SocketException: Connection reset by peer: socket write error
please reply if someone knows
thanks

These are basically the same error triggered in different places.
This occurs when the other end of the connection closes while the client is still writing to it.

Transaction dswp "Socket Error 10049 {Thd 5516} [socket #22A0BC, 0.0.0.0:19

Hi,
I just install SM 7.0 SR3 on HP-UX/Oracle 10.2. The installation finished ok.
I have done all configuration steps with satellite systems(ECC .0 Development, ECC 6.0 Test, EC 6.0 Productive), users, RFCs,... all of this steps finished ok. SO, I have created a Solution with the three satellite systems
I'm able to log on SAP Solution Manager system, also I've chequed java stack, both are working.
The problem is when I go to dswp transaction, operations->solution monitoring->System monitoring/administration, the systems doesn't appears, I have a message:

At tr. sm21, for today only appears a error: Run-time error "GETWA_NOT_ASSIGNED" occurred at 9:21. And If I reproduce the error, It doesn't generate other run-time error like this. So, I don't think that run-time error ocurred at 9:21 was related with my problem.

Two iphones one apple id and master reset

Here is my issue. I just got an iphone 4s for my hubby and did a master reset on his phone. I lost all the data after that. I also use my own apple id on his cell. Will that affect syncing data, music etc. on either phone?I am trying to fugure out the best way to have the phone working properly. So, on that note, should I have one apple id or two?
Thanks a bunch!

that's right, sync it with your library but also make sure that your sister does not do it again as it will keep changing.
You may wanna disable contacts sync with the iCloud on her device by taking her device and go on settings, iCloud & switch off contacts.

Socket Error on Recieve

Hi Experts.
when i try to export repository schema (or) Export Change file from the console, it is displaying "Socket Error on Recieve" and i am unable to perform any kind of operation.
I have repaired, refreshed, stoped and started repository and server, but i didn't get any progress on this.
Is any additional settings or operations need to perform at repository or MDM server level...?
Can any one help me what would be the reason for this problem...?
If this is a network issue, then what kind of things need to consider to resolve it..?
Thanks
Bharat

HI Bharat,
This is more to do with MDM server to Data base connectivity.
I think restarting the server can solve your problem,if it does not then check if the same problem exists for other repositories also.Also,check the MDS log file entry.
Thanks,
Ravi

How to handle write errors in non blocking sockets

Hi,
I'm using sockets registered with a Selector for read operations. I've seen code examples that put the SocketChannel in non blocking mode before registering it with the selector, and in fact not doing so would cause an IllegalBlockingModeException to be thrown.
My problem is that I can't handle write errors. The call to write() returns inmediately without throwing any exception. Even worse, when the network timeout expires the selector wakes up and I get an exception on read(). So I can't tell the difference between a real read error and a write error.
What can I do? Is there a magic method I haven't heard about?
Thanks

ejp wrote:
OK, so what happens is this: you write from your ByteBuffer; if there is room in the socket send buffer, the data is transferred and the transfer count is returned. (If there isn''t, the write returns zero and nothing has happened.) Your application code then continues. Meanwhile TCP is trying to send the data in the send buffer and get an ACK from the peer. If the peer is down as per your test, eventually those write attempts will time out. You will then get a connection reset exception on the next read or write.
Even worse, when the network timeout expires the selector wakes upCorrect, to tell you there is an error condition pending. This is good, not bad.You're right. This way my program can know that something happened.
But I still don't understand what the difference between a failed write() and a failed read() is. I mean, the error condition may appear during a send attempt, or it may appear after sending. In both cases I get an error when trying to read. How can my program know if data have been received by the other end?
Do I have to implement ACK messages in the application level protocol??? It'd be nice if TCP could do this for me...

Broken Pipe Error-unable to write to socket for second attempt

Hello,

I am able to write and read from socket for first time but when tried to write second time in the same sequence gives broken pipe error.

if I were you I would put the lines
kkSocket.setSendBufferSize(1024);
kkSocket.setSoTimeout (10000);
kkSocket.setTcpNoDelay(true);
before connecting to the server, not after the initial message was sent.

Imap performance and socket errors

SunOS vmpm1 5.10 Generic_141414-02 sun4u sparc SUNW,Sun-Fire-V490
We're experiencing imap problems that appear to be load related, and have had to restart mail services several times to restore service. The imap logs show a large number of socket errors. The server load average is in the 1-2 range; there's no apparent memory resource problem. We're seeing 600-1000 simultaneous imap sessions, which is a higher number than in the past. We run JMS & Communications Express on dedicated V490 SPARC server with 8GB of memory. We're planning to add an additional 8GB this Friday.
Our imap configuration settings are as follows:
-bash-3.00$ configutil | grep service.imap
service.imap.enable = 1
service.imap.enablesslport = yes
service.imap.idletimeout = 30
service.imap.maxsessions = 4000
service.imap.maxthreads = 250
service.imap.numprocesses = 1
service.imap.objectclass = top
service.imap.plaintextmincipher = 0
service.imap.port = 143
service.imap.sslcachesize = 0
service.imap.sslport = 993
service.imap.sslusessl = yes
Can you suggest additional troubleshooting steps? Do you recommend any configuration changes?
Thanks.

Questions:
1. Our JMS version info doesn't state whether it is 32 or 64-bit. Therefore, I assume we are running a 32-bit version. Is that correct?Correct. There is no 64-bit version of MS6.2.
2. Is there a virtual memory limit on the 32-bit version of JMS 6.2? Is the limit greater for JMS 6.3?The Solaris OS imposes the virtual memory size limit of ~3.75GB for all 32bit processes on SPARC. 64-bit processes have a much much larger limit.

"could not open socket" error

Hello:
I am following the book "Adobe Dreamweaver CS5 with PHP" by David Powers (an excellent book I might add) and am currently going over chapter 8. (Zending email). I have completed the section concerning processing of a simple user feedback script, and I beleive I have my connector script, and code correct. My testing server is running and correctly defined in DW. When I attempt to submit the form in a browser window, I get the message "could not open socket" at the top of the browser document window. I assume this involves adjusting a configuration file but I can not figure out where it is. Any help out there?
My setup:
Windows 7
Apache2.2.17
PHP5.3.4
ZendFramework-1.11.4-minimal

Boy, this one sure has me stumped.
Despite using the amendment to the catch block that you so graciously suggested, and turning off my firewall, and antivirus software, all I get is the error message "could not open socket" at the top of the browser (various) document window (and a resetting of all fields and textarea):
Here are my files. (I understand I will be changing my passwords, and getting a new recaptcha key, but I am desperate to fix this):
I also amended the mail_connector.php script using the (Outgoing Mail Server: (SSL) server306.webhostingpad.com (server requires authentication) port 465) choice below with the same result.
My hosting company provided this to me for manual setting of email:

Problem in using socket streams with encryption and decryption

Hi,
I am developing a client/server program with encryption and decryption at both end. While sending a message from client it should be encrypted and at the receiving end(server) it should be decrypted and vice versa.
But while doing so i got a problem if i use both encryption and decryption at both ends. But If i use only encryption at one (only outputstream) and decryption at other end(only inputstream) there is no problem.
Here is client/server pair of programs in which i am encrypting the outputstream of the socket in client side and decrypting the inputstream of the socket in server side.

**** I know that the CInput tries to read some header stuff thats why i used two threads for input and output.
Waiting for the reply.
Thank you.

Do not ever post your code unless requested to. It is very annoying.
Try testing what key is being used. Just to test this out, build a copy of your program and loop the input and outputs together. Have them print the data stream onto the screen or a text file. Compare the 1st Output and the 2nd Output and the 1st Input with the 2nd Input and then do a static test of the chipher with sample data (same data which was outputted), then do another cipher test with the ciphertext created by the first test.
Everything should match - if it does not then follow the steps below.
Case 1: IO Loops do not match
Case 2: IO Loops match, but ciphertext 1st run does not match loop
Case 3: IO Loops match, 1st ciphertext 1st run matches, but 2nd run does not
Case 4: IO Loops match, both chiphertext runs do not match anything
Case 5: Ciphertext runs do not match eachother when decrypted correctly (outside of the test program)
Problems associated with the cases above:
Case 1: Private Key is changing on either side (likely the sender - output channel)
Case 2: Public Key is changing on either side (likely the sender - output channel)
Case 3: Private Key changed on receiver - input channel
Case 4: PKI failure, causing private key and public key mismatch only after a good combination was used
Case 5: Same as Case 4

If I copy the "lcds" folder, Tomcat starts with socket errors

In the documentation it is said that when you create a new server-side application, you can start by copying the 'webapps/lcds' folder. I did that but then, Tomcat starts with some socket errors:
[LCDS]SocketServer 'my-rtmp-SocketServer' failed to pre-validate desired socket settings for BindSocketAddress: 0.0.0.0:2038
java.net.SocketException: Unrecognized Windows Sockets error: 0: JVM_Bind
[LCDS]SocketServer 'my-rtmp-SocketServer' failed to start.
flex.messaging.LocalizedException: SocketServer 'my-rtmp-SocketServer' cannot bind to accept client connections on port '2038' because another process has already bound the port. Please ensure that multiple endpoints across all applications are not configured to use this same port.
Am I doing something wrong?
Thanks,
Borek

What is happening is that you are getting a port conflict for the socket-based NIO and RTMP endpoints used in the channel definitions in the services-config.xml file of your new web app. The issue is that you have endpoints bound to the same port in the LCDS web and in your new web app.
You can deal with this one of two ways:
Option 1: In that services-config.xml file, search on "RTMP" and "NIO" to find the channel definitions and change the port numbers to something slightly different than the ones used in the LCDS web app.
Options 2: Move the LCDS web app out of the picture so it doesn't get loaded, and just use a template for future web apps. If you aren't using it for any of your development, there is really no reason you have to load it.
I'll add a note about this to the documentation that talks about using the LCDS web app as a template.

Problem with Java Proxy and Socket Connection

Hi Gurus!!
I have developed a Java Proxy that connects via socket with a Server Socket application. This Server Socket application accepts more than one connection at the same time.
When I connect the first time from my Java Proxy, the connection is correctly established. When the first connection opened, if a try a second connection, this is not established.
I use "new Socket(SocketServer,SocketPort);" to open the connection.
I think that all time the Java Proxy is trying to open the same connection, and this is a problem.
Is there a way to indicate to the server that is a new connection and that the existing connections remain?
Anybody could help me, please?
Thanks and regards,
Manuel Míguez.

Sorry!!!!i must give you more information.
The error which i have when i push the submit button is
HTTP Status 404 -
type Status report
message
descriptionThe requested resource () is not available.

My thought is that the error is in this line
String connectionURL = "jdbc:mysql://localhost/mybooking";in mysql when i write this code then the table opens with no problems:
mysql>show databases;
mysql>usebooking;
mysql>showtables;
mysql>describe booking;Furthermore i have added in my web application the library mysql JDBC driver my-sql-connector-java-5.1.6.bin.jar

Error in using the Socket Adapter while deploying the composite

I am going through a Socket Adapter sample given in Oracle JCA Adapters for Sockets"Oracle Socket Adapter Hello World".
This sample demonstrates inbound request/response and synchronous outbound request/response modes of communication using using Oracle Socket Adapter.
The HelloWorld business process takes an input string from the Socket Adapter inbound service and
publishes the message to the BPEL process.
The BPEL process invokes the Socket Adapter outbound service and returns the received string using synchronous reply.
Before going into this sample i did the configuration in the Weblogic server by following the steps below:-
1)Log into Weblogic server console
2)Click Deployments in the left pane for Domain Structure
3)Click Socket Adapter.The settings for SocketAdapter page is displayed.
4)Click the configuration tab
5)Click the Outbound Connection Pools tab, and expand java.resource.cci.ConnectionFactory to see connection
factories
6)Click eis/socket/SocketAdapter
7)Set the KeepAlive connection property to true
8)Save the setting.
After this i did the necessary configurations in the Socket Adapter Configuration Wizard(Inbound/Outbound).
The BPEL process has:-
1)A receive which receives input from a Socket Adapter which serves as an inbound synchronous service.
2)An invoke acitvity which invokes a socket adapter which serves as a outbound synchronous service.
3)Two Assign activites to do the necessary assignment.
After Deploying the sample i encountered with the following errors:-
<Sep 9, 2012 1:19:48 PM IST> <Error> <oracle.integration.platform.blocks.deploy.servlet> <SOA-21537> <Sending back error message: There was an error deploying the composite on soa_
server1: [JCABinding] [Middleware.ServerConnection/6.0]Unable to complete unload due to: Cannot locate Java class oracle.tip.adapter.socket.SocketInteractionSpec: Cannot locate Jav

Can any one please tell me the solution for this error.

Did you find a solution for this issue. I see the same error while deploying the same very sample code.

No more data to read from socket error.

insert (a.id,a.name) values ( b.id,b.name);This code is giving error : No more data to read from socket error.
But when I am trying
MERGE INTO TABLE1
( SELECT ...
FROM VIEW1*
where a.column1='test' ) a UNPIVOT ("VALS" FOR cols IN ( .....columns to unpivot.......))
) b ON ( a.id=b.id)
WHEN MATCHED THEN
UPDATE set a.name=b.name
when not matched then
insert (a.id,a.name) values ( b.id,b.name);It's working properly.
Any idea why I am getting error with code 1?

You need to look for an Oracle specific error code and message. The error text you have posted does not seem to be an Oracle error.
The error however could result from an ORA-3113 end-of-file on communication channel.
This Oracle error means that the Oracle server process servicing your request (executing SQL or PL/SQL code) ran into a fatal error (potentially an Oracle bug). The server process then proceeds with a "crash dump" - writes an error to the database instance's alert log, writes a trace file and then terminiates abnormally.
It terminates without telling the client and without tearing down the tcp client-server connection. When the client then attempts to use this connection, the socket read fails. No data to read as the socket connection no longer exists.
But this is speculation - we need to see the actual Oracle error (from the server or from the client driver). And you seem to be using an Oracle client that suppresses Oracle error codes and text. Which places a serious question mark over the actual usability of such client s/w for Oracle client-server.

Socket error 10038 on URLConnection

We put a Java 1.2.2 applet into production on our intranet starting in April. Of the more than 800 users (all running Windows and IE), 3 have been unsuccessful in getting it to work; the appliet will not make a connection to our application server via a URLConnection to a CGI. The error returned is a connection error, code = 10038, "Socket operation on a non-socket."
This week the applet failed for two more of our users who had been using it successfully. They both reported that a Windows application (Remedy software, I think it is their Help Desk product) had been upgraded.
Any ideas as to why our applet fails with the 10038 on a small number of machines? Or what other environmental factors (Winsock problems?, etc.) might cause the 10038 error as evidenced by the upgrade of another application?

We have same problem with 10038 error. It appears after installing Ws2help.dll in C:\Windows\System. This dll was required by "trillian", a instant messenger software. The problem disappears after removing this library.

Socket error in weblogic 7 when switching app to ssl

I am supporting an app that is running on weblogic 7.0.2.0. Because of security requirements I have been asked to enable SSL access and turn off the non-SSL listen port. I can enable the SSL port without issue but when I attempt to close the non-ssl port (so that users can only access via SSL) I get the following error in the log on startup.

Initially I didn't see this problem in validation, but now that I have restarted the admin server and managed servers in validation I see the same error in both environments.
Does anyone have an idea of what might cause this error?
Thanks,
-Mike

We faced with the similar issue in WLS 7.X after below Assertion error after restoring services we were able to resolve this issue for time being as per the weblogic there is a patch provided by BEA and this sort of issue is resolved.
This issue has been identified and updated under cars CR103525
