Requirement for client and server installation

Hi,
I am using Oracle database 10g and Oracle Developer 10g.I'd like to make a client server application.
1. What installation is required for the server side?
2. What installation is required for the client side?
3. I'd like the client to access the form application using internet browser.What are the configuration should I fullfil?
Many Thanks,
Imelda

Hi,
there is no client-server anymore in Oracle Forms. Its a web only deployment. So 1-2 no longer apply.
3) You need to install Oracle Jinitiator on the client or the Java 1.4 Plugin. Both can be configured for automatic installation.
See the Oracle Application Server documentation and whitepapers on otn.oracle.com/products/forms to learn about how to install and run Forms Services

Separate VDR client and server installs

Hi everyone,
I've just been playing around with VDR and I got it set up really quickly. I have a server box running my dvb stack including vdr with the streamdev plugin and I can watch tv on my desktop using vlc by opeing the vdr playlist over http.
What I was wondering was if I can install vdr client bit on my desktop (i.e. without needing the dvb dependencies) and have that connect to the vdr installed on my server? I was wondering if this might give a richer experience, one with a proper epg and so on...
When I installed VDR on my server there were loads of dependencies that I would not have expected: things like fonts and so on that themselves have loads of dependencies. Has anyone any thoughts on stripping down the server side to minimise bloat ?
Also any other thoughts on VDR if anyone's using it. What other things to try, etc... I'm going to tinker with the recording bit next...
The Arch wiki pages for vdr were a great help so thanks as always for great resources

DT require Oracle9i client and Oracle Services for MTS software

"Distributed Transactions require Oracle9i client and Oracle Services for Microsoft Transaction Server software."
I get the error above when attempt to run a COM+ transaction accessing Oracle9i. I'd been checked the installation of Oracle9i and Oracle Services in the client computer and it is ok.
I am using Windows Server 2003 and the database server is on another Windows Server 2003. The database is Oracle9i Enterprise Edition.
At Stanford's web site (http://www.stanford.edu/dept/itss/docs/oracle/9i/win.920/a95496/ch1.htm#1079911) I found Oracle's documentation that explains this, but it didn't worked for me.
Oracle Services is installed in both machines.
The Oracle MTS Recovery Service is running.
The COM+ component is registered.
When I use the same component with SQL Server 2005 beta 2 it works fine. What else do I need to do?
Thanks in advance.

Hi.
I have the same problem, one which works and another which don't (almost though).
I got most of it to work by taking the mtsservices registry entry from the server that works and put it on to the other after i have made the service in Oracle management console for mts.
Now i can search, delete, change but not make a new entry into the database.
And thats where i'm stuck now.
Hope it helps a bit..

Client and Server in one process

Hi all,
I am trying to create a process which can act as both Client and Server.
How can I do this?
Thanks!

AH. That's a better definition or explanation. Thanks.
This smells of a single process with multiple threads, each thread handling the basic needs of your requirements. In other words, have a thread deal with making one or more client type connections (use a main thread - the client controller - to spawn client-connection threads. This assumes you need multiplicity in your client-connection model.
Then make another thread - the server controller - to handle inbound connections, spawning a new thread for each inbound connection. Your main thread, the one that contains your main method, can watch everything that's going on and log or report what's going on in your client and server threads.
Going into specifics would be a lot to do here. Maybe someone is up for the challenge. Of course, this being a "New to Java Technology" forum, these concepts may be a bit beyond your skillset.
This is not the only way to go about solving your problem, but it's the only way I can think of at the moment given your requirements.
Hope this helps some.

Abap proxies ( Client and Server proxies)

Hi Team
Good day to you. I am now started doing some example scenarios on ABAP proxies(ie Client and Server proxies). After going through the blogs which are avialable, i am writing this question to you for clarification.
As per my understanding, the below are the required predefined settings which i need to do in my landscape to generate abap proxies(ie client and server proxies).
My landscape includes the below systems.
System A : SAP XI 3.0 system and
System B : SAP R/3 on WAS 620
SAP R/3 predefined Steps
1.Create HTTP connection in the business system.
2.Configuration Business system as local Integration Engine.
3. Connection between Business System and System Landscape Directory.
4. Maintaining the SAP J2EE Connection Parameters for LCRSAPRFC and SAPSLDAPI in SAP J2EE engine
(Here in the step 4, i found the below needs to be done)
1. Goto J2EE Engine
2. Choose Cluster --> Server --> Services. JCo RFC provider
3. Under RFC destination specify the following:
     Program ID: LCRSAPRFC
     Gateway Host: <Integration Server host>
     Gateway Service: <Integration Server gateway service>
     Number of process: 3
4. Under Repository specify the following:
5. Choose Set.
Application Server: <Integration Server host>
(i am not able to perform the steps which comes under point 4. so please Guide me how to goto J2EE engine and configure accordingly.
5. Maintain SLD access details in Transaction SLDAPICUST.
As per my understanding, i need to do the above predefined configuration steps in SAP R/3 system (ie bussiness System) for doing Abap Client or Server proxies.
And in the meantime, i would like to know whether i need to do any predefined configuration steps in XI 3.o system also. Please check and suggest me accordingly.
Once i get clarification on predefined configuration steps, i will proceed with the example scenarios on client and server proxies which are already in SDN.
Thanks in advance.
Regards
Raj

Hello Pavan
thanks for your response. you said that for the connection type 'H' we need to provide values for GATEWAY HOST and GATEWAY SERVICE but here i need to create the RFC destination of type 'T'. so please tell me whether i need to give the values for GATEWAY HOST and GATEWAY SERVICE for connection type 'T' also and the second thing is please tell me the difference between Application system and bussiness system accordingly to my landscape which i mentioned in my question.
I am in little confusion because as per the requirement for abap proxies in the blog they mentioned that all these setting should be done in the bussiness system (ie SAP R/3) but you are saying that Application system. so please clarify.
My landscape which i am going to use in Abap proxy generation
System A: XI 3.0
System B: R/3
Here which is bussiness system and which is application system. Pls calrify.
Thanks in advance.

Raj

Strange problem with SQLPLUS when client and server on the same box

Hi,
I have the problem with SQLPLUS when clinet and server on the same machine.
With client and server on the same machine i am running the command
sqlplus -l username/password@connect_identifier as SYSDBA.
With this command, even if you pass in wrong username or wrong password or both as wrong you can able to connect to database and execute queries.
Once Connect_identifier is correct and trying to log in as SYSDBA ,sqlplus will log in to DB with any username and password.
How to get rid of this behaviour. Is there any way to do this.
I am running this command by creating a process in C#
Edited by: user11000236 on Jun 16, 2009 10:31 AM

Thanks for the info.
How does Oracle/SQLPLUS allows any username or password to log in to DB with SYSDBA Privillages? What is the concept behind this.?
This is explainted in the above mentioned link:
Operating system authentication takes precedence over password file authentication. If you meet the requirements for operating system authentication, then even if you use a password file, you will be authenticated by operating system authentication.

Minumum hardware requirement for Siebel Document server?

what is the minimum hardware requirement for Siebel document server?

To install the Document Server, perform the following steps:
Obtain the required hardware.
Install the Siebel Server.
Install third-party applications.
After installing the Siebel Server, you may have to follow some of the steps described in Configuring the Document Server. The Document Server is a component of Siebel eDocuments, which can be installed during installation of the Siebel Server. Consult with your system administrator to verify that the Document Server has been installed and configured according to the requirements listed in the following sections.
Hardware Requirements
The Document Server is supported on the Windows 2000 platform. To maintain stability and performance, the Document Server must run on a dedicated host machine. The Siebel Server on this machine should host one instance of the Siebel eDocuments component group. No other components should be running other than required system components.
To support more users, you can run additional instances of the Siebel eDocuments component group on additional dedicated host machines.
Installing the Siebel Server
Install the Siebel Server on the dedicated host machine of the Document Server. For more information about installing the Siebel Server, see Siebel Server Installation Guide for Microsoft Windows.
During installation, you will have the option to enable component groups. Select the Siebel eDocuments component group. Do not enable any other component groups.
This step can also be performed after installation is complete, as described in the section Enabling the Component Group.
Installing Third-Party Applications
You must install Microsoft Word.
To install Microsoft Office
Log on to the server machine using the same user account that the Siebel Server NT service uses. This user account must belong to the Administrators group.
NOTE: The install must use the same account to be used by the NT Service. The installer configures COM security settings so that the installing user account will have the correct permissions to access and launch the application. If the install uses an account other than the Siebel Server NT service account, errors may occur when the Document Server tries to launch the application.
Install Microsoft Office using a Typical, or complete, installation. Verify that your version of Microsoft Office will install the Web Authoring Tools (HTML) component with the Typical installation. If it does not, you will need to use the Custom installation option, and install all of the typical components as well as the Web Authoring Tools (HTML) component.
Start the applications that will be used by the Document Server. This forces the applications to register themselves.
Close the applications.
Regards,
Joseph Arul Dass

I need to know the recommended systems & hardware requirements for clients P6 Professional and Client Web for P6 8.2
I mean what kind of processor, memory ram minimum and maximus to run or to deploy P6 Professional Client from P6 8.2 version and the requeriments to run the P6 8.2 Web application.

Hi,
Have you debug these two applications? Does it go into the catch exception block when you close the client or the server?
According to my test, it will throw an exception when the client or the server is closed, just log the exception message in the catch block and then you'll get it:
private async void Process()
try
while (true)
var data = await this.Receive();
this.NewMessage.Invoke(Encoding.ASCII.GetString(data));
catch (Exception exception)
Console.WriteLine(exception.Message);
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
By the way, I don't know what the SafeInvoke method is, it may be an extension method, right? I used Invoke instead to test it.

Communication between client and server

I am using sockets for communication between the client and the server. is there any other way that i can use for communication between the client and server???

Plenty of ways: JMS, SOAP, RMI, a RESTful API, writing-files-to-a-shared-directory-on-the-disk, Sneakernet, ...
Some of them use sockets (or better TCP/IP) as the underlying protocol.
But to give you a good answer, you would have to tell us why you want a different way. I hope you're not searching for a different way just for the sake of being different.

Socket communication between client and server

Hi all,
I am doing an assignment for communication between java client and java server using sockets. This communication is in the form of XML documents. I am facing a problem in this communication.
Actually at Server side I'm creating an XML document(Document type object) using DocumentBuilderFactory in javax.xml.parsers package and transforming this Document into a stream using StreamResult.
My code is :
Transformer xmlTransformer = TransformerFactory.newInstance().newTransformer();
StreamResult xmlString = new StreamResult(currentClientHandler.getSocketOutputStream());
DOMSource xmlDocSource = new DOMSource(xmlDocument); // xmlDocument is Document type reference
xmlTransformer.transform(xmlDocSource, xmlString);
so, this xmlString(i.e. StreamResult) is passed directly into the output stream. Here I need to close() output stream after transform() call to help SAX parser to know about end of stream.
Now at Client side, I am parsing this stream using SAX parser. It parses this correctly. But when sending some another data back to Server when client opens output stream, it given Socket closed exception. I know that closing input or output stream closes socket. But in my problem, I have to send data in streams and not by using files or byte[] etc.
So what is nearest solution to problem ??
Plz help me. Any kind of help will be greatly appreciated.

hi
thanks for ur reply.
I didnt get any error msg while getting the back the datas.
Actually i divided my application into two parts.
My application will act as both server and client.
server ll get the browser request and send to the client and the client will send that data to the c++ server.
Im able to do that.and unable to get the data from server.
Didnt get any error.
can u tell me how to make an application to act as both client and server.
I think im wrong in that part.
thanks a lot

Enterprise Hotfix Rollup for Win7 and Server 2008 R2 via WSUS

I stumbled across the fact that Microsoft released a hotfix rollup for Win7 and Server 2008 R2 that contains 90 hotfixes
http://support.microsoft.com/kb/2775511/en-us
The articled I linked above talks about after installing 2775511 (the big hotfix rollup containing 90 hotfixes) it is also necessary to install three more hotfixes:
After this update is installed, you must install update 2732673 to fix a regression issue in the Rdbss.sys file
After this update is installed, you must install update 2728738 to fix a regression issue in the Profsvc.dll file
After this update is installed, you must install update 2878378 re-released on November 11, 2013 to fix a regression issue in the Advapi32.dll file
I have imported all four of these hotfixes into my WSUS server. Do I need to install 277551 first and then install the other three or can all four be approved and go out at once? I guess I am hung up on the language of "After this update is installed
.... ". I want to put all 4 of these on our Win7 machines as well as my 40+ WinServer 2008 R2 machines

I read somewhere that over half of the updates included in Win7 SP1 and WinServer 2008 R2 SP1 were originally released as hotfixes. This means Microsoft made the decision that a large number of hotfixes would benefit every user of these two OSs
I think your conclusion is flawed. The only thing that you can draw from the presented statistic, is that Microsoft determined that a significant percentage of updates originally released as hotfixes warranted the additional investment in regression testing
to subsequently release those hotfixes as updates.
The fact that they bundled these 90 hotfixes together leads me to the same conclusion.
In fact, exactly the opposite conclusion applies: What you have in this package is all the rest of the stuff that didn't make that cut. What you have in this package are still NOT-regression tested hotfixes, they've just been bundled up for easy deployment
(and note that three of them got further broken in the process of bundling), causing yet three more hotfixes to have to be released.
In fact I read the MS Team Blog about this big hotfix release and they say the same thing, all users of these OSs would benefit from the installation of this hotfix rollup, not just a subset of users.
I suspect there are a notable number of patch administrators and systems administrators who would disagree with that self-serving promotion. If, in fact, it's true that "all users" would benefit, then the product team should have invested the effort in properly
regression testing those hotfixes, and releasing them as REAL updates. They did not; ergo the *actual* value is less than claimed.
Of course the bugaboo here is the fact that three other individual hotfixes need to be installed after the big hotfix rollup is installed.
Exactly! (And those are just the attempted fixes that broke something. Who knows how many other "fixes" may still result in newly discovered "broken stuff" that was never broken in the first place.)
The second part of this question should revolve around an itemized review of the hotfixes contained in this rollup with one simple question asked for each:
Have we actually *experienced* the issue addressed by this hotfix.
Where hotfixes are concerned one very simple but important rule applies:
If it ain't broken, don't try to fix it!

UDP Client and Server

I am trying to run a UDP Client and Server by running the server first and then the client. But when I try to do that I get the message java.lang.NoClassDefFoundError: UDPServer and java.lang.NoClassDefFoundError: UDPClient. I have included the code below. Can you please help. Thank you.
UDPClient.java:
import java.io.*;
import java.net.*;
import java.util.*;
public class UDPClient{
    public static void main(String[] args) throws IOException{
      Date d=new Date();
      long time1, time2, ETE, sumETE, maxETE, avgETE;
      if(args.length!=1){
          System.out.println("type java UDPClient <hostname>");
          return;
      time1=d.getTime();
      DatagramSocket s=new DatagramSocket();
      String st=new String("dldfjsdkjf");
      byte[] buf=new byte[256];
      buf=st.getBytes();
      InetAddress address=InetAddress.getByName(args[0]);
      DatagramPacket p = new DatagramPacket(buf, buf.length, address, 8777);
      s.send(p);
      p=new DatagramPacket(buf, buf.length, address, 8777);
      s.receive(p);
      time2=d.getTime();
      ETE=(time2-time1)/2;
      s.close();
UDPServer.java:
import java.io.*;
import java.net.*;
import java.util.*;
import java.lang.*;
public class UDPServer{
public static void main(String[] args){
    try{
      UDPServerThread ust = new UDPServerThread();
      ust.start();
    catch(IOException e){}
UDPServerThread.java:
import java.io.*;
import java.net.*;
import java.util.*;
import java.lang.*;
public class UDPServerThread extends Thread{
DatagramSocket s=null;
BufferedReader br=null;
PrintWriter pw=null;
public UDPServerThread() throws IOException{
    this("UDPServer");
public UDPServerThread(String name) throws IOException{
    super(name);
    s=new DatagramSocket(8777);
public void run(){
      char[] ca=new char[10];
    //while(true){
      try{
          byte[] buf = new byte[256];
          DatagramPacket p = new DatagramPacket(buf, buf.length);
          s.receive(p);
          String st=new String(p.getData());
          for(int i=0; i<10; i++){
              ca=st.charAt(i);
buf=st.getBytes();
InetAddress ad = p.getAddress();
int port = p.getPort();
p = new DatagramPacket(buf, buf.length, ad, port);
s.send(p);
catch(IOException e){
System.err.println("Failed to run the server");
System.exit(-1);
s.close();

this has nothing to do with your code, but how you are running it. It is a classpath problem.
You should go to the directory where the UDPClient.class is, and type
java -classpath . UDPClient
similarly for the UDPServer

Requirement for client and server installation
