Connection reset by peer:/Broken pipe using JTurbo JDBC Driver
I am using the JTurbo JDBC driver to connect to a SQL Server 7.0 database. I am using Connection Pooling. After roughly an hour or so, I am no longer to get connections from the pool. Exceptions thrown are "connection reset by peer", followed by "Broken pipe" exceptions on every subsequent getConnection call.
Has anyone found a successfull resolution to this problem using the JTurbo JDBC driver for SQL Server 7.0? I have tried the "autoReconnection=true" option on the URL string for the driver, but this has had no effect.
I am running the Resin app server, version 1.2.7, on Solaris 8 and connecting to a SQL Server database running on NT 4.0. The JVM on Solaris where the servlet is running is 1.3.1.
Any help is greatly appreciated!

I do not have an idea about your application server but i do know how i solved it in weblogic. Just see whether this is helpful to you.
Points to be sure of........
1) Make sure that when ever you request a connection from a pool, after you are done with it return it. If you are not returning it and trying to use that reference again, this problem will occur.
2) Look at the capabilities of your app server. Set the connection pool such that
a) All the connections are checked at regular interval with some default select statement from any table in the database.
b) Connections are check when the connection is checked out and returned to the pool.
I the connection object is not ready , close it and create a new one. The app server which manages the pool should implement these feature so that when you get the connection - its the tested and working object.
If your app server does not support - then think of ways you testing it before you using it(Anyway this is not the good solution).

Connection reset by peer, broken pipe...
This part of sockets is just needlessly confusing. Perhaps someone can shed some light on this?
Sometimes I get an IOException with as message "Connection reset by peer". Other times, it's "broken pipe". What is the difference? Why isn't there a way other than parsing the exception message text to figure out if it's a client 'hanging up on you' unexpectedly or something else?
Secondly, in my NIO server, all webbrowsers, but for some reason firefox especially, really likes to make a full request, than grab 0 to 99 bytes (the full return HTTP message size is much larger than that), and then silently hang up and immediately re-request the same resource again. Sometimes 10 to 15 times in a row. Firefox shows no errors of any kind when it does this. the read() operation on the socket returns -1 which is what ends up causing the close.
Is this because '-1' doesn't really mean: The socket is closed, it actually just means: the socket INPUT is closed but you can still send?
And if it is the latter, how the heck do I detect a connection in lockdown state in a non-blocking environment?Sometimes I get an IOException with as message

Is this because '-1' doesn't really mean: The socket
is closed, it actually just means: the socket INPUT
is closed but you can still send?It actually means a one-way close originating from the other end, which could be the result of either a close or a shutdownOutput() by the peer. If it was a shutdownOutput() you can indeed still send.
And if it is the latter, how the heck do I detect a
connection in lockdown state in a non-blocking
environment?What do you mean by 'lockdown state'? If you mean how do you detect when the peer finally closes after a shutdown, the answer is that you eventually get a connection reset when writing, which is where we came in. If you have a socket channel which has detected EOS as above and you don't have any more data to send to it, close it. -
Trying to insert a Large CLOB : connection reset by peer
I am Trying to insert a Large CLOB .. i get this error message
java.sql.SQLException: Io exception: connection reset by peer
I am using a prepared statement to insert a Clob. It works fine with small data.
Thanks for your help in advance.It might help if you gave more information - this probably depends on your database and driver, so giving info on them will help.

Broken Pipe/Connection Reset By Peer IO Exceptions
Can someone explain what causes a connection reset by peer exception vs.
a Broken Pipe IO exception? I realize they are generally caused by
someone hitting stop, closing their browser, hitting a different link,
etc.. but I was trying to understand what might cause a connection
reset by peer exception vs. a broken pipe exception. I've added code to
my servlet to suppress the "Connection Reset By Peer" socket exceptions
but I'm wondering if I should do the same with Broken Pipe. Also, are
there are other types of similar exceptions that can occur when users
get impatient.. Thanks

"Connection reset by peer" using firewall between iFS API and Database
Hi ..
We have a webapplication running on a websphere server using the iFS API to connect to a iFS schema through a firewall ( PIX ). The firewall will close idle connections after a while, and this results in "Connection reset by peer" errors in our application.
Firewall guys says that configuring the firewall not to close connections, is not an option.
Does anybody have experiences with this, suggestions on how to deal with this?
We are running iFS 9.0.1.
Thanks
Anders Monrad
Danisco ITI'm having the same problem, using a PIX firewall, however, I have the firewall setup between OHS & OC4J, also between OC4J and our application database.
I have a solution for the OC4J and app DB. If I set the expire_time = 10 in sqlnet.ora, this will ensure that sqlnet will ping the connection between OC4j and the DB every 10 minutes, thus the firewall will not close the connection due to inactivity.
However, does anyone have a solution for the OHS & OC4J connection? Can this be resolved with configuration rather than having to use an app to ping it?
[I realise I could write an app to retrieve a page every so often to keep the connection open, but I want to do it with configuration]
Thanks in Advance. -
Socket read error: connection reset by peer
Hi.
Has anybody experienced the error message �Socket read error: connection reset by peer�
Please see below for detailed information.
Appreciate your help
Regards
RT
Enviroment specification
Server: HP/UX 11.00 64-bit, Oracle RDBMS 8.1.6.0.0 64-bit
2 firewalls between client and db.
Client:
Win 2000,
SP3,
Oracle Client 8.1.7.0.0 ,JDBC OCI (thin JDBC driver,class12.zip)
JDK 1.3
JRUN3.0
The TCP protocol is being used in the communication
Error messages
Web Users receive: Socket read error: connection reset by peer
Trace files on the sever: Read unexpected EOF ERROR on 18.
Explanation: The error in the server sqlnet trace file, suggests that a client connection has terminated abnormally, i.e. client machine powered off, a cable removed or a network connection aborted without warning. No user has complained of such a problem and there is no client trace with an error.
The problem
The users of the java web application, experiencing an exception almost once or twice a day.
The JRUN web-server reports broken connections to the db and client are receiving "connection reset by peer".
At the moment when the errors occurs the users just have to wait a while(2-10 min) and then they can use the web application again.(no action is taken)
This problem can not be reproduced. The problem happens only occasionally when the network is under heavy load and new DB connection is being created.
The application
The java web-application uses a customized connection pooling against the database. This pool is shared among all the users of the website. whenever a user process needs to fetch data from the database, a free connection from this pool is allocated. The application is testing if the connection is valid before making a transaction (select '1' from dual). When the error occurs a ORA-3113 end-of-file on communication channel is returned to the application.
The path between the client and db involves at least two firewalls. The firewalls are opened for sql*net traffic. The network group can tell that enquiries from the app.server is not getting feedback from the db. They have not however, identified if the enquiries are reaching the db-srever, or if they are stopped earlier in the network.
Around 1000 users, are using other applications which uses dedicated sqlnet connections against the db and they have not experienced any problems.
Issues considered
Connection pooling
It is a customized connection pooling, developed by Lindorff developers.
I have read through the source code for the connection pooling and it does the job as it should, and in case of bad connection, it tries to create a new connection.
The log file shows that the call to the method DriverManager.getConnection() hangs until the server goes down, which is probably because of the fact that the method DriverManager.setLoginTimeout(), does not take effect and timeout value is Zero. ( According to oracle , Oracle JDBC does not support login timeouts and calling the static DriverManager.setLoginTimeout() method will have no effect).
Firewall
One thing to consider is when the firewall may decide to shut down the socket due to long inactivity of a connection. This will cause problems to JDBC Connection Pool because the pool is not aware of this disconnection at the TCP/IP level; until someone checks out the connection from the pool and tries to use it. The user will get a Socket read error: connection reset by peer.
Jrun timeout paramter is less than the firewall�s timeout so the firewall will not close a connection before Jrun does.
Number of processes the DB can handle
Processes parameter is 1300, , they have not experienced the Oracle error msg �max # of processes reached�.
Port redirection through a firewall:
Since the firewall has a sql net proxy Port redirection through a firewall is not a problem. Problems with port redirection only appear at connect time, but in this situation the connections fail long after the connection is established.
The network group
The network people who investigaged the problem at Lindorff report that there are a significant amount of "dropped packages" between the database server and the jdbc client (web-application) 24 hrs. The reason for this is "unknown established TCP packet" which means that the firewall does not consider these packages to be part of an already established session. The network group believes this happen because one of the hosts send a RESET or FIN signal which the firewall have noticed but are not received by the other host.
It seems like the firewall are dropping packages bacause of "Unknown
established TCP packet" from both the JDBC client and the TNSLISTENER on the database server. The dropped packages are SQL*Net v2 traffic so clearly Oracle products are involvedPresumably something is working.
Thus the problem is not with your code. At least not the database part that you have control over.
That error occurs when the other side closes the socket. Presumably you are catching lost connection exceptions and trying to restore it. -
JCO - Connection reset by peer - after 5 minute timeout
Hello
We're using SUP with the JCO Connector. This has been working flawlessly since project inception. Now, after switching to a new data center (Windows Server 2008 Server Enterprise Edition, SP2 on VMWare) we're observing a mysterious behavior with timeouts of idle connections. I hope someone in this forum knows what this might be.
JCO connections originate from SUP servers. When such connections are idle for more than 5 minutes they get disconnected from SAP -- this is in agreement with SAP timeout parameter of 300 seconds.
On our new systems we noticed that requests sent 5min+ (after timeout) show following error:

JCO 2.1.9 AMD 64-bit (contains librfc 6.40) but replaced this with librfc 7.10 (after seeing Note 825494). Behavior was exactly the same. We did confirm in jco/rfc trace that those versions were actually used.
Any ideas?

Connection Reset by Peer Error
I was working on an application at work and migrated the code and database to my machine at home so I can work on it there as well.
It works fine on my work machine but when I run it at home it consistantly fails on the database connection statement with a "Connection Reset by Peer". I can connect to the database fine using the oracle tools so I know the database is up. I thought it was my firewall but I turned that off and the problem remains. I'm using the latest JDeveloper and an oracle 9i database and tried various JDBC drivers (classes12.zip..which is what I'm using at work, classes12.jar, and the newest drivers from the Javasoft site.) I also set it up using the forte IDE (thinking it may be a JDeveloper setting) but that didn't do it either.
Any clues why this might be happening? I've been searching the internet for some insight but to no avail.
Thanks
WendyCheck the database's alert log. Are you using database links? Look into that.
AS 9.0.2.3 is antique. It should have broken down already much earlier. Please move to a more stable version as soon as you can. You will not regret it. -

XI 2.0 Inbound file adapter : Connection reset by peer
I am using XI 2.0 and have an inbound file adapter. It polls every 5 minutes. But at least 1 or twice a day the file adapter stops with the following error message.
"java.net.SocketException: Connection reset by peer: JVM_recv in socket input stream read" occurred \par
There have been times when this runs for days or weeks without any problems.
Has anyone else seen this issue and how do your correct it?
Currently I have to go into the file adpaters and restart them manually. It would be nice if there was some way to automate this function. Any ideas?
Regards,
JimWith JDK 5.0 use ojdbc5.jar instead of ojdbc14.jar.

JCOM throwing SocketException: Connection reset by peer: socket write error
I have an ejb which is calling a simple ActiveX component using JCOM.
Ocassionally the ejb loses the ability to connect to the ActiveX component. Any attempt to call a method results in a java.net.SocketException: Connection reset by peer: socket write error.
However the ActiveX component continues to run correctly. I can still connect to it using a vb test client. This is using com to connect, not DCOM as used by JCOM(JIntegra).
The application server and the ActiveX component are running on the same server.
Any suggestions as to why the JIntegra DCOM request could be failing?
Thanks,

Looks like the browser user is closing the browser or moving on to a new url before the response comes back.
Search the newsgroup, as there are a number of posts concerning this.

Connection reset by peer problem
I have the following code, and every time I run it i get a "java.net.SocketException: Connection reset by peer: socket write error" exception. Why is that? This is the first time I'm writing a network client application, so please help :)
Socket s = new Socket("127.0.0.1",8080);
OutputStream out = new BufferedOutputStream(s.getOutputStream());
InputStream in = new BufferedInputStream(s.getInputStream());
out.write("server status\r\n".getBytes());
//out.flush();
StringBuffer responseLine = new StringBuffer();
int c;
while(in.available() > 0) {
c = in.read();
responseLine.append((char)c);
//out.close();
//in.close();
//s.close();
System.out.println(responseLine.toString());P.S. It's the same problem with or wothout the out.flush(), and with or wothout closing my streams and socket.InputStream = new BufferedReader
Um..just look at that code, oh boy.
InputStream is a class and so is
BufferedReader
Two different classes (event if they are subclasses)
cant be directly assigned to each other.The human eye sometimes sees what it wants to see and not what it is... :-)
I think the problem is with the protocol and the timing. The while loop may never execute due to timing:
1. Client's "server status" request takes a few ms to arrive in the server.
2. In the meanwhile, in.available is zero and the client does not enter the loop and does not append any characters to the string buffer.
3. Server writes its status on the socket which arrives at the client which is no longer reading it a few ms later.
Which brings us to the protocol:
If the server status is a fixed length block of data, try reading it into a single byte buffer.
If it is variable length or text, use a BufferedReader on the socket, read the response a line at a time and make the server end the report with a token (like a last line of "END_OF_SERVER_STATUS_REPORT" or "01234567890123456789012345678901234567890123456789", whatever).
Don't check if data is available on a socket if you know it should be, sooner or later, and you don't want to multiplex your flow on data availability. -
Io exception: Connection reset by peer: JVM_recv in socket input stream read
We are developing a new J2EE app using JDev, OC4J, servlets, and EJBs. We have determined that our firewall is closing database connections that have been idle for 1 hour. This is a security requirement that cannot be changed. When we try to use these idle connections in both stateless and entity beans, we consistently receive this or a similar error message:
"ServletSACategoryList: Error invoking EJB procedure. Exception: java.sql.SQLException: StatelessSysAdminBean::getCategoryList - Io exception: Connection reset by peer: JVM_recv in socket input stream read "
Environment:
Oracle 9iAS 9.0.2.0.0
Database: Oracle 8.1.7
JDBC 8.1.7
JDK 1.3
JDev 9.0.2.829
We are using the ejb-location attribute within data-sources.xml for JNDI lookup of the DataSource. Here is what this file looks like:
<data-sources>
<data-source
class="oracle.jdbc.pool.OracleDataSource"
name="jdbc/OracleDS"
location="jdbc/OracleCoreDS"
xa-location="jdbc/xa/OracleXADS"
ejb-location="jdbc/OraclePoolDS"
url="jdbc:oracle:thin:@###.###.#.###:1521:dev1"
connection-driver="oracle.jdbc.driver.OracleDriver"
username="????????"
password="????????"
max-connections="4"
wait-timeout="20"
min-connections="1"
inactivity-timeout="60"
connection-retry-interval="1"
max-connect-attempts="3"
/>
</data-sources>
After calling getConnection() on the Connection object in my stateless bean, I have tried checking if the Connection object is null or isClosed(), I have caught any Exception, and looped to try again, but nothing has worked.
Please respond to [email protected] or directly to this post if you can help in any way.
Thank you,
- RobHi Robert,
If you don't mind, I can only offer a few suggestions for things
to try -- I'm afraid I don't have a solution for you. Of-course,
you may have already tried these things, so please excuse me if
this is the case.
Firstly, your "data-sources.xml" file looks "different". Have
you read the "Data Sources" chapter of the "Oracle9iAS Containers
for J2EE Services Guide, Release 2 (9.0.2)"? It is accessible
from here:
http://otn.oracle.com/docs/products/ias/doc_library/90200doc_otn/web.902/a95879/ds.htm#1004903
Also, have you tried running OC4J in "debug" mode? This web
page has more details:
http://kb.atlassian.com/content/atlassian/howto/orionproperties.jsp
I get the impression from the information you have supplied,
that you may not be explicitly closing your database connections
in your code. It looks to me like you are obtaining a database
connection in your session bean, and then keeping it for the
lifetime of that bean. Is that correct? I think it's better
to obtain a connection when you need to interact with the database,
and then close the connection immediately after completing the
interaction with the database (but that's just my opinion).
Lastly, if you haven't already discovered them, these web sites
may also be of help:

Hope this helps you.
Good Luck,
Avi.
