Excessive cxs socket connections created for ejb access

We are seeing a large number of TCP connections being created to the cxs engine for ejb access in our application.
We are running iPlanet application server 6.0, sp3 on Solaris 8. We have a web application that accesses a singleton component running in a kjs engine. That singleton accesses cmp entity beans and stateless session beans for serving client requests over the RMI/IIOP bridge. When three clients are connected and making requests, the number of TCP connections to the IIOP port (9010) starts to increase until everything freezes. I believe the "freezing" of the client apps is due to the open socket limit of 1024 being exceeded. According to the developer doc we can increase rlim_fd_max to 8192 to fix that problem.
However, my question is why are there an increasing number of socket connections? We are caching the ejb instances in the singleton so we should not be creating a large pool of EJBs. I have verfied the large number of sockets using netstat and also using RMI runtime logging in the kjs engine.
Does anyone have any ideas what could be happening here?
Thanks,
Mark

I noticed that most of the TCP connections are made to port 32787. Can anyone from iPlanet tell me what is listening on this port? The large number of socket connections is really tying up server resources.
Thanks,
Mark

Servlets or EJB for Persistent external socket connections

We have a Servlet that establishes a socket connection to another
external server and sends and receives messages. We have the Servlet defined as pre-loaded when JRun starts.
When JRun is started, the Servlet is started and connection is
established with the external server. The problem is when a new message is being sent, the Servlet is instantiate again and the connection is stopped and restarted. We do a forward request from another Servlet to this.
Am I totally misunderstanding Servlets because reading articles
and books seems to indicate that I should create an EJB instead of a
Servlet if you want a persistent connection.
Thanks in advance for your help.

I assume then that your connection to the external server is achieved in the "init" method of your servlet. Therefore every time the servlet container is called upon to accesss your servlet, it instantiates it - thus a new connection will be being made each time.
I would take out the connection properties from the init method. I.e. you only want it to happen once.

Socket connection access denied

I created a class that handles all the socket level calls for my Applet class. When I'm trying to open the socket, I get an exception saying "access denied (java.net.SocketPermission 172.16.11.63:3333 connect,resolve)". When I open the socket within the Applet class, it opens fine. I would think the socket class would have permissions to the socket because it's being loaded from the same host and the same directory as the Applet. Can someone please explain this to me? Thanks.

Normally a webserver runs on port 80. If you're connecting to port 3333, then that counts for a different host.

Please see the following:
1. Create an entry in Trxn DBCA for SQL Server in SAP, you are creating a database connection for the SQL server in SAP.
2. You use this connection, and write Native SQL stmnts...between EXECSQL...ENDEXEC to fetch the data..and then normal ABAP statements to put that data into your ztable.
TABLE DBCON Entry can be like this...depends on your External database..

Problem: Socket connection is not creating in machine, through utility program (MFC Dll), on ListDisplay service port - 3334 (on separate machine), while we are able to telnet on same ListDisplay service port - 3334 from same issue machine on same time

Problem: Socket
connection is not creating in machine, through utility program (MFC Dll), on ListDisplay service port - 3334 (on separate machine), while we are able to telnet on same ListDisplay service port - 3334 from same issue machine on same time
Environment: -
OS:
Windows XP SP2/7
Code:
VC 6.0
Dll: MFC
Problem Description: -
We have written a utility program which create socket (Using windows standard method [MFC]), and then make connection with another service (List Display) running
on port 3334 in different machine and retrieve the required list data. This program was working fine in almost all the machines.
But, we have received a severe intermittent issue on two machines. Client is facing issue in displaying the list data from port 3334.
Attempt: -
First we tried to debug code, and we come to know that socket is not creating in utility program. So we tried to telnet on ListDisplay service port 3334 and we were surprised that we were able to telnet, then we opened some more
telnet window on same port 3334 around (6 to 8) window, and each cmd connected properly. But we were not able to create socket from utility program.
Problem is severe because issue is intermittent.
We have tried all the way, but we are not able to figure it out, that what can be the exact problem and what are the conditions, when utility program will not
connect with ListDisplay service on port 3334.
Kindly assist to resolve this issue. For any help, we would be really thankful.

Hi,
According to your description, it seems that you have created an utility program which is making connection with another service port 3334, however, two clients are facing issue in display the data list from port 3334.
Port: 3334/TCP
3334/TCP - Known port assignments (1 record found)
Service
Details
Source
directv-web
Direct TV Webcasting
IANA
Since the port 3334 is used by directv-web service, I'd like to suggest check this service it is working well on the problematic clients.
1. The client can be resolved in DNS well? Please run "nslookup" in the prompt command.
2. Is there any 3rd party application interrupting? Do test in clean boot.
2. Strongly suggest you run process monitor tool to analysis it.
I am looking forward to your reply if you have any updated on your side.

Problem creating a connection pool for mssql server

Hi
i downloaded the microsoft type 4 driver for JDBC and i have installed it. now i am trying to create a connection pool for MS Sql server but each time i ping i keep getting an error telling me
Operation 'pingConnectionPool' failed in 'resources' Config Mbean. Target exception message: Connection could not be allocated because: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket
please can someone help out on this
Ifeanyichukwu

I assume that you installed the driver correctly. You did go into the app sever admin and set the JVM path? You do this by going to Application Server | JVM Settings | Path Settings and putting in an entry for Classpath Prefix.
If that is done and it's not something basic like your database isn't turned on, then it must be your settings. To to Sun's site and search for dbping. http://developers.sun.com/prodtech/appserver/utilities/dbping/dbping_overview.html
Deploy this program and run it. It is a very simple tool that lets you test different property settings. Play around with different settings until you get a ping.
If that doesn't work post your connect pool settings.
Good luck

NullPointerException in Nokia when creating socket connection

I need a socket connection, The following code works well in simulators.
But in my nokia it throws a NullPointerException,
st.setText("Trying To Connect");
try{
client = (StreamConnection)Connector.open("socket://example.com:6040",Connector.READ_WRITE,true);
st.setText("Connection Estableshed");
is = client.openInputStream();
rt = new ReaderThread(this,is);
rt.start();
os = client.openOutputStream();
wp = new WriterProgram(os);
}catch(IOException ex){
st.setText(st.getText()+ex.getMessage());
I can see "Trying to connect".
But I never see "Connection Established".
NullPointerException thrown says nokia.

Hi,
If all the users belong to the same role (like all users are Publishers or Writers), then, you can send a single connection key for all the users. But, if users belong to different roles, then, you will have to create connection keys for each role and then send it to the users.
Hope this helps.

Creating socket connection error

My problem is when I have router in local host, my client works fine, but when I move router to an other computer, then creating topic connection gives me error like: error creating socket connection to 127.0.0.1:14001, message: Connection refused: no further information
(I use port 14001, in local host it works). Why does it dry to connect to localhost? If I put up router in localhost too, it starts sending messages to this one!?
Anyway maybe this problem might have something to do with changeing the router version (swiftmq1.0 to 2.1.2)?
Could anyone help me with this one, I'm in big hurry, router and client should work on monday :-(
Thank You!

Thanx 4 answer :) neville
I have the answer allready - just I had to add 1 row in routers properties file, like:
swiftlet.sys$jms.listeners.plainsocket.bindaddress=192.168.0.1
It was in the SwiftMQ documentation, but I was to lazy to read all of it. My fault.
But thanks again for trying to help! And I WILL read that jndi doc.

To create a Web Service for EJB

Hello,
I created one WS for my EJB which has one method it returns array type of java bean. The bean has 8 properties, but the WS has been showing only one property when i test the WS.
But it is displaying all properties when i use servlet.
I would appreciate ur suggestion.
Regards,
Krishna.

Hi,
Check out whether u have followed all this steps:
1)Create an Ejb module project and then inside this project include a Enterprise bean project.
2) Create a getter and setter methods in the bean.java and call those methods in the local.java and the main java file.
3) Then rebuild the application create an archive for it.open a new ear project in the j2ee pers.
4) Next step is to create a virtual interface and a webservice in ejbjar.xml.After completing all rebuild and deploy the newly created EAR file.Now this webservice will be added to the server.
5) GO to the WD appln, in the model create a model and then give the necessary proxy settings.If the file is in the local server then no need for giving UDDi or URL u can directly take it from the server or url itself.
6) After giving the connections open the data modeller to map all the model nodes from the new model that we created latest.Then in the implementation u can direcly call the webservice request that u want.This req instance should be created in the comp ctller and then binded to the node.
Hope it helps,

Nagarajan.

How to Create a Single Backend Socket connectivity in a Server Socket Pgm

Hi Everybody,
I have a written a Server Socket which connects to back end socket and receiving the data and sending back to the front end. But as per my client requirement i need to create only one socket at the back end. But the code I have written is creating new sockets for each request. Is there any way to use the single client socket connection for all the transactions. I have attached the sample code for the reference.
import java.io.*;
import java.net.*;
import java.nio.ByteBuffer;
import java.nio.channels.SocketChannel;
public class serl implements Runnable
ServerSocket serversocket;
Socket clientsoc;
Socket fromclient;
PrintStream streamtoclient;
BufferedReader streamfromclient;
SocketChannel socket_channel=null;
Thread thread;
public serl()
try
serversocket = new ServerSocket(1001);//create socket
clientsoc = new Socket("10.100.53.145",200);
socket_channel = clientsoc.getChannel();
catch(Exception e)
System.out.println("Socket could not be created "+e);
thread=new Thread(this);
thread.start();
public void run()
try
while(true)
PrintStream streamtobackend=null;
BufferedReader streamfrombackend = null;
fromclient=serversocket.accept();//accept connection fromclient
streamfromclient=new BufferedReader(new InputStreamReader((fromclient.getInputStream())));
//create a input stream for the socket
streamtoclient=new PrintStream(fromclient.getOutputStream());
//create an a output stream for the socket
String str=streamfromclient.readLine();
//read the message sent by client
System.out.println("Output Input From Vtcpd "+str);
streamtobackend.print(str);
streamtobackend = new PrintStream(clientsoc.getOutputStream());
//create an a output stream for the backend socket
streamfrombackend = new BufferedReader(new InputStreamReader(clientsoc.getInputStream()));
//create a input stream for the backend socket
str=streamfrombackend.readLine();
System.out.println("Output From Backend Client"+str);
streamtoclient.println(str);
}//end of while
catch(Exception e)
System.out.println("Exception "+e);
finally
try
fromclient.close();
catch(Exception e)
System.out.println("could not close connection "+e);
public static void main(String ar[])
new serl();
}

Srikandh,
Create a singelton pattern for you socket ( IP, port, etc..) and each time you read the input stream and write to the output stream, do the following to the socket to reset it in the working thread
fromclient.getInputStream().mark(0);
fromclient.getInputStream().reset();Hope this could help

Is there a command syntax that we could give to see all the users who have been created for access to a particular database. I want to view all the users that have been created using sql* plus.
can anyone help or is it impossible?
Thanks

This is for begging:

Than you have to select also all the users that have granted roles with this privilege
this will give you the full set of users who can connect

Create Apps for HTTP access

Hi,
Is there a way to create apps for HTTP access instead of using UNC?
And have it access via Application Explorer?
Thanks,
Harold

Do you mean an app to launch a web page via IE/NetScape?
Just run "IEXPLORE.EXE" with the webpage as the parameter.
Of do you mean HTTP connectivity for the workstation to run an app?
The 2nd starts to exist in ZFD4 in some fashion , but not ZFD3.

Creating a TSL/SSL socket connection to a server

Hi
Is it posible to create a TSL/SSL socket connection to a server with as3 - webapp, I foundSecureSocket but it seems like it is only for Air, and is not in the flex 4.5 sdk?
Then NetConnection has it, but can you use it with a server that we have created our self? I think I read that if we use flashremoting, we can?
We are using As3Crypto but there is a lot of overhead on using this, as it is not native code.
