How to track IP's of clients connecting to DB server through Apps Server

My Application server address is like http://192.220.0.75:7779/forms90/f90servlet form=TEST.fmx&userid=@abc
I can connect to Apps server from any computer using explorer with this address .
for auditing when I connect to db server through Apps server then my audit table detect only server IP- 192.220.0.75 each time but when I connect by oracle DS or toad then my audit table detect each computers defferent IP address.
how can I detect different users and IP addresses connecting to database server using apps server instead of apps server IP?

You can try to use WebCache event_log, this one will show your clients IP or you can uncomment UseWebCacheIP ON in httpd.conf file, so you ensure that the access_log show the ip of the user and not of the server.
Greetings.

How to restrict max number of client connection per extend server?

Does anybody point me or tell me what is the vm property or config element I need to put so that an extend client will not accept more than specified number of connections at any give point in time.

Hello,
Look at http://coherence.oracle.com/display/COH34UG/acceptor-config the <connection-limit> should do what you want.
Thanks,

Am i on the right track for establishing my client connection with BC4J?

I am developing web-application with BC4J JSP project now. However, I find the auto-generated page not that useful as they are not flexible enough. Then, I decided to write coding by myself. But the first problem is - how to write the coding for client connection? To make maintenance easy, I would like to place those connection code in a class file instead of hard-coding each connection details in my JSP or Servlet page.
Question 1: Through the examples I search in my JDeveloper (Candidate 2) directory, found a file TestClient.java in the \BC4J\samples\Caching\src\demo directory with the following codes:
// Create an instance of the application module by name, using local mode
String _am = "demo.DemoModule"; // Fully-qualified application module name
String _cf = "DemoModuleLocal"; // Configuration name for connection info
ApplicationModule am = Configuration.createRootApplicationModule(_am,_cf);
// Find the Managers view object by name in the application module
ViewObject mgrVO = am.findViewObject("Managers");
// We're done with the AM instance, so release it
Configuration.releaseRootApplicationModule(am,true);
Is it for testing only or really useful for the production environment? Am I doing the right thing if i use such method to establish my web client connection? What's the pros and cons for using this method? Any other better alternatives?
Question 2: As I know BC4J automatically takes care of connection pooling as a default manner since version 3.2. Can I still use the following statement
session.setAttribute("user_name", user_name); //Set session attribute
String user_name = (String) session.getAttribute(user_name); // Get session attribute
to capture and assign client session correctly for individual clients?
Question 3: What codes should I use to achieve 'Transaction' update, which assembles the coding as follows:
Connection.setAutoCommit(false); //disable auto commit
connection.commit();
connection.rollback();
connection.close();
Thanks for answering!!!

What's the pros and cons for using this method? Any other better alternatives?The Configuration API (createRootApplicationModule, releaseRootApplicationModule) will work. However, please note
that it is intended for java clients that will hold an ApplicationModule reference for a long duration. The BC4J web
frameworks (represented, for example, by the ApplicationModule and ReleasePageResources tags) all use the
SessionCookie interface to acquire/release ApplicationModule instances on a per request basis. This will allow
better scalability. Please see the pooling sample / documentation / javadoc for more information about using these
APIs. The pooling sample servlet is located in \BC4J\samples\Pooling\src\demo\TestPoolServlet.
Question 2: As I know BC4J automatically takes care of connection pooling as a default manner since version 3.2. Can I still use the following statement
session.setAttribute("user_name", user_name); //Set session attribute
String user_name = (String) session.getAttribute(user_name); // Get session attribute
to capture and assign client session correctly for individual clients?BC4J will not interfere with your use of the HttpSession context. How do you intend the "user_name" to be used? Do
you intend it to represent the DB user, JAAS user, etc. If you intend it to be used as the DB user you will need to declare
the "user_name" to BC4J. Please see:
http://technet.oracle.com/products/jdev/howtos/bc4j/howto_dynamic_jdbc.html
Question 3: What codes should I use to achieve 'Transaction' update, which assembles the coding as follows:
Connection.setAutoCommit(false); //disable auto commit
connection.commit();
connection.rollback();
connection.close();ApplicationModule.getTransaction().commit();
ApplicationModule.getTransaction().rollback();
If you are using the Configuration or SessionCookie APIs, as mentioned above, then the connection lifecycle will be
managed for you. So, you should not need to invoke connection.close().

Hope this helps.

How to make the client connect to the server at the command prompt?

I found this code on IBM's website, it was a training session on servers and clients using java.
The code compiles fine and the server seems to start up properly when I use java Server 5000. I think whats happening is the server is running and listening for a connection on port 5000.
When I try to run the client I get the following error.
Exception in thread "main" java.lang.NoSuchMethodError: main
I see a start() method but no main. As far as I know, applications should all have main, it seems as if the person who wrote this kinda confused applets with application. Not that I would really know what happened.
If you have time, could you tell me if there's an easy fix for this? I would love to have this client/server working if it isn't too much trouble. As I have looked all over the net for a free client/server applet that will actually let me see the java code and none of the free ones do allow getting to their source.
Most of them allow you to customize them somewhat but also have built in advertising that can't be removed.
This is the closest I have come to finding one that lets me look under the hood. But alas it doesn't work out of the box and I don't know what to do to fix it.

Finding the clients connected to a server

Hai Friends,
I am doing a project in grid computing. I have developed a socket program for the client and server side using java and multithreading.
I want to know the number of clirnts connected at a particular period of time and also the IP addresses of the client.
Can anyone please suggest us the code for doing that.

Create an object that describes each client. Something like:
public class Client
    private Socket socket;
    private WhatEver whatEverDataYouNeed;
    ...whatever methods you need...
}When a client connects create one of those objects and store it in a suitable data structure, e.g. LinkedList. When a client disconnects remove from list.
There should be a method in Socket that gives you the IP address, see the javadoc for Socket.

Can 11g client connect to 10g server?

I am very new to Oracle, so hope this isn't too basic of a question. I thought I saw something through my searches where the clients were backward compatible to older versions of the server. Will this work, 11g client connecting to a 10g server?
I have a custom windows app that uses the Oracle client to pull data from an Oracle server at another location and pushed the data into a MS-SQLExpress database for a local cache to be used during th day. I do not have the source for this custom app or the time to re-create this custom app. We just installed a new Windows 2008 R2 (64bit) server and I just need to get the client back on the new server so the custom app will work again. The old server was running 8.1.7 client, but going to 64bit OS I want to use a more current client to avoid issues with 32bit/64bit compatibility problems.
I am downloading the 11g 64bit client now, but want to make sure I'm not wasting my time and need to get a different client. Please advise.
Thanks!

In general, yes, you can use a later version of the client to connect to an earlier version of the database and vice versa. But that only generally works for a few major releases. Unfortunately "10g" and "11g" are somewhat ambiguous-- both could be referring to one of two major releases.
Metalink 207303.1 is the client/server interoperability matrix. If by 11g you mean 11.2 and by 10g you mean 10.1, the 11.2 client will not work with a 10.1 database. If the client is 11.2 and the database is 10.2, it should be at least 10.2.0.2. If the client is 11.1, the database should be 10.1.0.5 or 10.2.0.2 or higher.

Echo to all clients connected to NIO server

I am writing a NIO xml socket server that uses NIO.
My model implemensts a producer / consumer system where client connections are accepted and processed by a specified number of worker threads.
I would like to be able to broadcast a message to all clients that are connected to the server.
Opinions / suggestions I am sure that this is quite a common type of functionality.
Kind Regards

Accendia server is implementing a callback mechanism that allows the server to notify the client.
This is not broadcast, you would have to call each client (www.accendia.com). For real broadcasting use datagram or multicast sockets (depends on different factors) on both client and server in addition to the sockets used as part of the NIO server.

Accendia server allows the server side to invoke callback objects on the client. You can't do real broadcasting, though, you would have to iterate through all client connections. See if it helps:
http://www.accendia.com
If you need real broadcasting you can use datagram or multicast sockets on both the server and client side.

Lion clients connectivity to lion server 10.7.4

i have been having issues connecting Lion clients running 10.7.4 to the mac mini running lion server 10.7.4
The issue started after i did a clean install of lion server. I configured everything correctly by downloading server admin tools, turning on the open directory, and creating a master open directory for the server. i then created both a test account and a generic account to see if the accounts will work when a client trys to connect. The lion clients had no issue connecting to the server but when the Mac would restart, a red dot would come on the side saying all network accounts are unavailable. I am not sure what is happening and yes i have checked the DNS portion and everything is in working order.

Can you boot into the Recovery HD? If so, run both
Disk Repair and Repair permissions on the OSX volume.
Also, if you have a bootable clone of your previous install,
try booting into it and see if the problem persists.
If you have a Time Machine backup, try to restore to
a point before the upgrade.

How to add 10.8 managed clients to 10.8 server

Specifically, using Workgroup Manager 10.8 rather than Profile Mgr.
Previously, you could point your clients to the OD Server using Directory Assistant (or via Users & Groups in 10.7) which would then become available to add to a Computer group you had created in WGM. Even though I've got mine set up that way, WGM 10.8 can't see any of 'em. Is there another prerequisite I'm not aware of? Or does this method no longer apply to clients running 10.8?
thanks.

I'll check but I wouldn't doubt it. You can add clients in Profile Mgr. that way too (it's the only way you can add them AFAICT). If you can't browse for available clients, why bother with WGM? They're just adding extra layers of administration hassle in my opinion to make you collect and submit UUIDs in order to bind clients.

How do I get SQL Developer to connect to SQL Server.

I have downloaded SQL Developer but I see no option to connect to SQL Server in order to do the database migration. I found a document that said to download the MSSQLSERVERMIGRATION.ZIP file and it said to unzip the file. There is no instruction as to where the files are going. Can someone point me in the right direction?

Hello,
did you read the following from the SQL Developer online help:
Before Migrating From Microsoft SQL Server or Sybase Adaptive Server
To configure a Microsoft SQL Server or Sybase Adaptive Server database for migration:
Ensure that the source database is accessible by the Microsoft SQL Server or Sybase Adaptive Server user that is used by SQL Developer for the source connection. This user must be able to see any objects to be captured in the Microsoft SQL Server or Sybase Adaptive Server database; objects that the user cannot see are not captured. For example, if the user can execute a stored procedure but does not have sufficient privileges to see the source code, the stored procedure cannot be captured.
Ensure that you can connect to the Microsoft SQL Server or Sybase Adaptive Server database from the system where you have installed SQL Developer.
Ensure that you have downloaded the JTDS JDBC driver from http://jtds.sourceforge.net/.
In SQL Developer, if you have not already installed the JTDS driver using Check for Updates (on the Help menu), do the following:
Click Tools, then Preferences, then Database, then Third Party JDBC Drivers.
Click Add Entry.
Select the jar file for the JTDS driver you downloaded from http://jtds.sourceforge.net/.
Click OK.
For further reading I recommend to start on this page:
http://www.oracle.com/technetwork/database/migration/sqlserver-095136.html
It contains a demonstration "Creating a connection to Microsoft SQL Server".

Email client connects to BT server but does not do...

Windows 8.1 and latest version of Thunderbird. When I run Thunderbird it connects to the server, logs on, and begins to check for new messages. At this point it stops - none of the new messages are downloaded to my laptop. However, messages in my outbox get sent (and arrive at their destination). This is happening with both main and sub account emails. My wfe has a Samsung Galaxy phone and has the same problem with her emails, so I think it isn't related to Thunderbird - the problem must be with the BT servers? Does anyone agree?
Solved!

It took a very long time to open BT Mail this morning, after logging in - a matter of several minutes. Perhaps there was a server problem.
However Microsoft Outlook 2013, set as a pop3 account, responded as normal.
(I do an occasional login to BT Mail to check the spam folder, as pop3 doesn't see the BT Mail spam folder).

CSS How do I show which client connected to which server?

I have a few servers load balanced on a CSS 11501. I want to know which server a particular client IP is connected to - what command do I need?

The commmand I use is "show flows 'IP'.
Replace 'IP' with the actual address of the client you're looking for.
