"Connection reset by peer" Help Me

Question

Hi
I have j2re1.4.2_08 and Oracle 9.2
When I tried to update database with huge data I got following exception:
java.sql.SQLException: Io exception: Connection reset by peer: socket write error
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:179)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:333)

at edu.bnmit.BookDBUpdateThread.run(BookDBUpdateThread.java:80)
at edu.bnmit.BookDBUpdateThread.update(BookDBUpdateThread.java:46)
at java.lang.Thread.run(null:-1)
method used to update database is:
void update(Books b[]){
Connection dbConnection;
PreparedStatement stmt;
try{
dbConnection = DriverManager.getConnection(
dbConnection.setAutoCommit(false);
String sqlStmt = "UPDATE Books SET " +
"bookName=?, bookAuthor=?" +
"WHERE bookId=?";
stmt = dbConnection.prepareStatement(sqlStmt);
for(int i = 0; i < b.length; i++){
stmt.setString(1,b.bookName);
stmt.setString(2,b.bookAuthor);
stmt.setInt(3,b.bookId);
stmt.executeUpdate();
dbConnection.commit();
stmt.close();
dbConnection.close();
}catch(SQLException e){
System.err.println("Error While Updating Table");
String s = e.toString();
StackTraceElement trace[] = e.getStackTrace();
for(int j = 0; j < trace.length; j++){
s += "\n\tat "
+ trace[j].getClassName() + trace[j].getMethodName()
+ "(" + trace[j].getFileName()
+ ": " + trace[j].getLineNumber() + ")";
System.err.println(s);
}Orcale server is distently placed. I get this exception when I send 10,000+ records to update.
Can anyone help me.
Thanks

[Just a note: the stack does not match the code posted here. In the stack, executeUpdate() is called from BookDBUpdateThread.run() whereas your code shows that it's called from BookDBUpdateThread.update().  It helps to post the correct stack/code.)
The problem might just be that you have an unreliable connection. The fact that you have a long running operation is just exposing connection drops that may otherwise go unnoticed.
I suggest that you test this over a more reliable connection. If that is not possible, split the update into multiple shorter running updates. Of course, this would only work if the updates do not require a single transaction. If a single transaction is required, you can use your own XATransaction (the details on XATransactions are beyond the scope of this forum.)
