Tomcat Io exception: Connection reset

The error occurs after a little while and I need to stop start the entire tomcat before the pages can retrieve data from oracle again. I saw many posting on this which some says its related to browser closing before the end of page load, dbstmt.close etc...can someone pls direct me on which is correct.
the print stack is as follows...
HTTP Status 500 -

I'd guess it's a database problem. Probably something to do with the way you open and close database connections, or the nature of the link to the Oracle server. It might even be an authentification problem.
The problem is that there's a third trace block not being displayed here. The servlet exception probably also has a "root cause" exception which is not being printed on the trace. You may find more information in Tomcat's log files, but then again you may not.
You may want to think about putting an explicit try - catch block in the offending jsp as a debugging aid and, thus, catching and displaying the expception in an "unwrapped" state.

Io exception: Connection reset - after some time interval

Hi,
We are facing a problem in connection while implementing connection pooling using OracleDataSource .
Application is running with out any issue if it is called continuously.
If we call the application after some time interval, connection is being reset. We are able to get the connection instance but connection reset exception is thrown while calling callableStatement.execute().
If application called after application restart it is working fine.This issue is happening only for the first few calls made after some time interval.(after 1 hr)
After that call is proceeding without any issue.

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"

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,

Hi 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:
http://www.orionserver.com
http://www.orionsupport.com
http://www.elephantwalker.com
Hope this helps you.
Good Luck,
Avi.

Io exception: Connection reset

Dear,
my scenario is: SAP MII accesses an Oracle database and reads messages form this database to subsequently send to a webservice.
For some messages, with size of 4K, the MII can complete the process successfully.
For other messages that have size of 89K, the error occurs:
: com.sap.xmii.Illuminator.logging.LHException: com.sap.xmii.Illuminator.logging.LHException: com.sap.xmii.Illuminator.logging.LHException: Error occurred while processing records; Io exception: Io exception: Connection reset
How can I solve this problem?
Best Regards,
Sérgio Salomã

You need to determine where the issue is occuring. How are you calling the transaction? Do you have proper error handling under the sql and web service actions?

My RMI Server application Not work under Linux: Exception: Connection reset

Under Red Hat Linux 8.0 my RMI server application, when I try to bind the Impl class, sends me the exception:
"java.rmi.UnmarshalException: Error unmarshaling return header;
nested exception is: java.net.SocketException: Connection reset".
And it works under Windows 2000 without any problem.
What could it be?
Many thanks,
Ales.

Hi Ales,
Try to change your /etc/hosts file, and change the line that says :
127.0.0.1 MDK localhost.localdomain localhost
(where MDK is the machine's name).
Remove MDK from this line and add a new one mapping it to a 'real' outside IP address, visible (check firewall!!!) to the network from where you are approaching the Linux Box
Good luck,
Aart

HI everyone..
I got it..
well the first thing we have to take care is the the host name
host name should match your mail id...
eg:
<your mail id>@<domain>
now even for exchange server the domain remains same... ask your administrator(exchange) to give u smtp host name not the one used in your MS outlook express. only the id part will change.. if u can get this id properly then this code works fine..
Cheers
Ram
ps: And never ever instantiate the properties object, always get it from System class..

Exception: Connection Reset

Whilst sending a medium amount of data over a socket it stops receiving and if i terminate the client the server sais that he had a connection reset. Can anyone tell me whats the matter?

Till now at the same stage of sending data not the code. the code runs fine for a couple of times but then hangs. Other communication isnt p[ossible anymore...
Part of the server
[code]
class DoRadar
extends TimerTask {
ServerControl sc;
String Vessel;
double Range;
public DoRadar(ServerControl sc1) {
sc=sc1;
public void setRadar(String v, double r) {
Vessel = v;
Range = r;
public void run() {
Vessel w=null;
for(int a=0; a<sc.Player.Vessels.size(); a++) {
Vessel v = (Vessel)sc.Player.Vessels.get(a);
if (v.Name.equals(Vessel)) {
w=v;
break;
if (w==null) {
sc.pw.println("Vessel not yours or not found...");
} else {
sc.pw.println("$base new");
for (int a=0; a<sc.gc1.Bases.size(); a++) {
Base b = (Base) sc.gc1.Bases.get(a);
double r2 =

Hi Shantanu,
You can not modify the value for the file field - this facility was blocked a while ago for security reasons.
You can, however, disable the field to stop the upload taking place. In your javascript code that copies the path into your hidden item, add in:
filefield.disabled = true;
When submitting a page, only those items that are not disabled are submitted - normally this is a pain, but it helps here!

Andy

Connection Reset exception received in Windows only

Hi,
I have two instances of my java app, one on Windows, one on Linux, both connected to the same cpp app running on Linux, and the machine running the cpp app is very heavily loaded. After some time, only the windows java app gets a Socket Exception (Connection Reset), not the linux.
In fact, after connecting to the cpp app, the java app starts a number of transactions with the cpp app, requesting data from the cpp app. The trasanctions are timing out on Windows, but not on Linux.
Does anyone have any idea why this might be happening?
Thanks for any help,
Regards,
Shefali

Hello,
I have the same problem. My java TCP client detect disconnection (Connection Reset exception is generated) after about 60 seconds. With Suse 10 it make more then 15 minutes!!!!
This is not normal of an application that it takes that long to detect a disconnection! Is there a way of changing/configuring the timeout of the TCP/IP layer of the OS?
Thanks in advance for your help.
Alain.

Io Excpetion Connection Reset In OWB Mapping

Hi,
While executing a mapping in OWB i am getting an error Io Exception Connection Reset.
This happens when execution of mapping involves more than 50 lakhs of records.
Please any one can help.

You say: "But the connection is taking more than expected time".
So I am think of a network issue. Check the DNS and/or entries in the HOSTS file if they are according to the prereqs.

Connection Reset issue in Weblogic 8.1

Hi,
We have an application running on weblogic 8.1. Please let men explain the steps that we carried out:
1. A new user was being enrolled through the applciation.
2. To make the connection object the value of the properties DriverClass, ConnectionURL, UserId and Password was obtained from the config.xml.
3. preparedStatement.executeUpdate() inserted data in the database.
This works fine initially but when i leave the system idle for an hour or so and then try to access the application we get an error:

For those interested, I have some updates on this subject and someone out there sent me a mail asking if I ever found anything out.
Basically, when I encountered this issue the first time, I was working on a SP2 Portal. We were having numerous small bugs like this one with SP2 that centered around the back button or refresh button. BEA gave us a "super patch" back in July or so that when applied to our SP2 project, fixed our issue. I have sense moved onto SP3, and I did not see the compression issue (so I think SP3 must have the patches correctly setup...like I would assume it would).

Connection reset when inserting file to BLOB column

Friends,
When inserting a file to a BLOB clomun and the file is more than 1KB, I receive the following message: java.sql.SQLException: Io exception: Connection reset
The code is this:
int fileLength = (int)file.length();
System.out.println("File length: "+fileLength);
int cod = (int)(Math.random() * 1000);
String sql = "INSERT INTO BLOB_TABLE VALUES(?,?)";
try {
FileInputStream fis = new FileInputStream(file);
PreparedStatement pstmt = connection.prepareStatement(sql);
pstmt.setInt(1, cod);
pstmt.setBinaryStream(2, fis, fileLength);
pstmt.executeUpdate();
System.out.println("File insert sucess!");
connection.close();
Does anybody know what this can be? My database is oracle.
Thanks!

When you create objects on the database they are stored in the data dictionary by default in UPPER case.
So in this line:
src_loc bfile := bfilename('example_lob_dir', 'example.gif'); -- source location
you need to reference the name of the directory object in upper case. e.g.
src_loc bfile := bfilename('EXAMPLE_LOB_DIR', 'example.gif'); -- source location
;)
