Multiple Remote Client Terminal Sessions to OS X server?

Windows Server's terminal services allow multiple users to log in to server through Remote Desktop Connections. Can OS X Leopard or later do that for the OS X clients?

How to register remote client in java to a Corba server in C++

Hi All,
Although i know that it spossible for to have a Corba client in java and Corba server in C++.What am nto sure is whether i can have this client and server on 2 different machines.In a vwgue way i think it shoudl be possible but not sure.
I have Server running in Corba in one machine, how to register java client on another machine to this server .??
Thanks,
Ranjitha

Hi,
You can do that by defining the DB link to use while you register the function.
From the Administrator go to "Tools-> Register PL/SQL Functions..."
Fill in the information of the function (name, display, owner ...)
And in the "Database Link" choose your new DB link.

Remote Desktop (Terminal Services) Configuration on a Server Standard 2012, standalone installation

I'm new to this, so bear with me..
I need help locating documentation on how to configure a Server Standard 2012, standalone server, to act as a terminal server. In server 2008, you could have the server as a domain controller, and also host remote desktop sessions for thin clients. Apparently
a lot has changed with 2012, and I don't think I'm even using the right search terms because I having a time finding proper information.
I'll be glad to provide whatever further information is needed for someone to help me..
Thanks in advance, and looking forward to gaining a better understanding of how this works. Don't mind doing the work, like I said, i just need some good documentation I can follow.

Hi Ashun8
Please not be in rush as your SD & MM consultant need to testing some scenarior on sandbox.
As being Basis expert! you should have many comprisions including patch level on both server before initiate the Remote Client Copy.
I will prefer to do the system copy instead the Remote Client copy without downtime on PRD server.

It doesn�t work lazy loading with remote client (toplink)

I am trying to use lazy loading in a @ManyToOne field but I get an exception. I have been reading in some oracle tutorials that it's necesary use -javaagent:.../lib/toplink-essentials-agent.jar for that it works because this argument activate dynamic weaving in JavaSE. I have put this command line argument javaagent but it doesn't work. Why? Can I have to do another thing? I have done a lot of tests in base to comments read in another forums but I only obtains an exception.
Caused by: java.io.IOException: Mismatched serialization UIDs
NOTE: The server use toplink and the remote client query the entitties through a session bean of the server. Besides, I am using Glassfish (Sun application server and toplink).
Thanks in advance.
hayken

At first, thank you for your reply.
I know that I haven´t explained the problem too well. I have a stateless bean with one remote method that execute a query an returns an entity like this
@Entity
public class ModuloEntity extends Serializable
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long idModulo;
private String nombre;
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="IdProyecto")
private ProyectoEntity proyecto;
The remote client invoke this method and in that moment I get this exception.

If I look the server log, I can see that the call has not been produced, it doesn´t show any exception. It looks that the object managed by the server and the remote client aren´t the same and the corba service doesn´t work when remote client call session method. If I change the ModuloEntity and remove the fetch attribute then all this process executes correctly. The problem is in this attribute.
NOTE: I am using the javaagent command line argument.

Minimal requirements for remote client app to call a EJB 3 session bean

I'm just starting to get into EJBs, trying to learn the EJB 3 APIs. I kind of understand the setup on the server side to create a session bean. What I don't understand is what I would have to deploy for each of the remote client app (Swing-based GUI or something like that) installations. Of course, the client app code would have to be deployed to each client desktop, but what stuff related to the session bean? Just the session bean interface class?
For ease of discussion, let's say my bean is CalculatorBean, having two interfaces, CalculatorRemoteIface and CalculatorLocalIface. Let's also say my client app, CalculatorUI, is a simple Swing-based GUI that grabs a reference to a CalculatorBean.
Other than just the Swing-based classes and the JRE, what JARs/classes will I want to deploy to each desktop?
(Please assume the latest Sun Java System App Server 9 and Java EE 5, if you are familiar with them.)

Personally- I would deploy your backend
in EJB 3.0, but then expose it as a web service. It
is MUCH easier for your clients to connect to a web
service (and mantain that code), then to have them
connect via RMI/JNDI.Oh, I would say it's quite the opposite. RMI/JNDI is MUCH easier from a client point of view than web services. To make web services work easy from the client side you have to generate code and the tools that generate code from a web services wsdl file doesn't do a great job today. But that was not the question. But take some time reading this article about webservices...it's quite funny and spot on: http://wanderingbarque.com/nonintersecting/2006/11/15/the-s-stands-for-simple
Now to your question, yes you will need the remote interface on the client side.

Multiple remote sessions to same machine

Hi everybody,
is there a way to allow on Leopard multiple remote graphical logins? I would like to connect to my account using VNC or ARD remotely while a user is logged in locally. Is it possible to do that without a third party software? If a third party sw is necessary what would you suggest?
Thanks in advance for any help,
Paolo

Hello,
All data is sent to all replicas that need the data at the rate at which they can consume. So to answer your question, no because it doesn't care where the replicas are it just needs to get it the data. What you could do is put some type of compression wan
accelerator on each end but the data stream by default is already compressed with availability groups so I'm not sure how much extra help that may give.
If you want to verify this out for yourself, packet capture the mirroring endpoint setup for AOAG on every replica.

Can 1 instance of Windows 8.1 ENTERPRISE host multiple Remote Desktop connections?

I am shopping for the components for building a machine with fair, high-performance hardware. I have Windows 8.1 Professional. I wanted to know if either Windows 8.1 Professional or Windows 8.1 Enterprise can support multiple remote connections
from users outside the local network. For example, my brother is based in San Diego, CA and has an underpowered laptop. Is there any way to make a remote connection over that much distance, from San Diego to Northern Virginia, from a RDP client running Windows
8.1 Professional to a RDP "server" Windows 8.1 Professional/Enterprise machine, and run a modern, single- or multiplayer- game over smoothly that connection? At the very least, is it possible to run common
apps (e.g. Microsoft Office 2013 IE 11, Adobe Acrobat XI) smoothly on a Windows 8.1 Pro RDP client connected to a Windows 8.1 RDP "server" located 2250+ miles away?
Would upgrading my installation from Professional to Enterprise improve the responsiveness and display quality for my remote users?
I know Windows Server R2 2012 has features specific for handling remote connections, but I am trying to keep a Windows 8.1 user experience. Still, if anyone can show some evidence that Windows Server 2012 R2 Remote Desktop Services (RDS) improves display
and responsiveness over long-distances for remote (RDS) connections, then I will shop for Windows Server 2012 R2 Standard instead. The huge drawback of Windows Server 2012 R2 Standard CALs is the enormous cost to enable 3-5
remote connections for family, non-commercial use.
Has anyone attempted to host long-distance remote access, non-commercially, for 3-5 connections? Has it worked well? What, in general, is required?
T. Webster

Hi,
It depends on the quality of the network connection to run the software smoothly throuth RDP. And I don't think the quality would be better if you upgrade to Windows 8.1 Enterprise.
Windows 8.1 allow only one session of RDP, the Remote Desktop Server in Windows other than the Windows Server edition has a limitation to allow only one concurrent user per session by default, i.e. if someone remotely connects to the computer over RDP then
whoever was logged in at that moment will be automatically logged off, even if that user is physically present at the computer. This is by design.
Regarding more information about RDP, please take a look at the following articles:

Terminal Server Session Management: why do we need a rdp session to take control of a terminal session?

Hi all,
As title, I have this question: why do we need a rdp session to take remote control of a terminal server session?
I copied tsadmin and related file to a windows 8.1 pc and I'm able to see for every terminal server the list of users logged in, but the option "take control" is greyed out... why? is not possible to avoid this block?
Thanks in advance
Davide

Hello, Davide_ita.
Also tried to use RDSM to "Remote Control" user's sessions, but in this thread
Remote Control
with Remote Desktop Services Manager - error Access is denied (Windows Server 2012 R2)
I get the recommendation to use RDP or Remote Assistance.
The quote of
TP []:
Hi,
You cannot remote control a session on a 2012 R2 RDSH server using Remote Desktop Services Manager. You need to use the RDP 8.1 mstsc.exe or the RDS gui in Server Manager on 2012 R2. The command you would use with the RDP 8.1 client would be
this:
mstsc /shadow:<sessionid> /control

A hint if you use multiple mail clients to check one IMAP account

FYI:
Mail.app in leopard turns on an advanced "push" mail feature automatically, called IDLE. This can cause strange problems when you use multiple IMAP clients to access you IMAP server.
For instance, I have a computer in my office and one in my lab. Normally Mail.app is running on them both constantly. After installing Leopard I would sit in my office delete and move messages from my INBOX, and when I went down to the lab I would find those emails still in my INBOX and also in the mailboxes I had moved them to on my office machine. In very short order I ended up with multiple copies of emails in many places and no ability to actually delete mail.
Originally I thought this was a bug with Leopard Mail.app, or a problem with compatibility between Mail.app and the UW IMAP server that I use. I wasted significant time searching on the web for possible solutions.
It turns out that the IDLE feature (that is automatically turned on for you in Leopard) was the cause of my problems. Turning this feature off (in the Advanced pane of the accounts setting) on EACH machine caused me email to return to its previous functional state.
If you only use one IMAP mail client the IDLE feature is nice, it pushes new mail to you as soon as the IMAP server receives the new mail.
(note -- IDLE is also automatically turned on in Thunderbird)

Assuming you're on a NAT'd network, DNS services can cause all sorts of weird errors with the mail server, including spontaneous name changes.
To verify local DNS services, launch Terminal.app from Applications > Utilities and issue the following harmless diagnostic message:
sudo changeip -checkhostname
You'll need to enter an administrative password for the sudo, might see a one-time informational message around the usage of sudo, then you'll see some host and network configuration information, and finally an indication that either no changes are required, or that there are local DNS or the network has configuration issues. Also, make sure you're not using .local or .arpa as the top-level domain within the DNS services.
Public DNS for the mail server can also cause communications issues, if that's not configured correctly — that won't cause the issue you're seeing in the logs here, but it will cause inbound mail to not reach your server, and outbound mail from your server to be dropped by the remote server. To verify your public DNS, launch Terminal.app from Applications > Utilities and issue the commands discussed in this thread or this thread and confirm that your internal and external MX record and your internal and external forward and reverse DNS settings are all correct.

Terminal session not supported by your computer

I can login to my work environment but when I try and initiate a remote session link to my work computer, I get an error message that says "This terminal session is not supported by your computer."
I need to be able to log in and remotely access my PC at work. Any suggestions are appreciated.....

what OS on your work computer? What is already installed on it to allow remote control? Is that software enabled?
If remote os is MacOs - Apple Remote Desktop is actually server component, I mean it is not included in desktop MacOs of your home mac. But search can help.
If remote os is Win - you need this: http://www.microsoft.com/mac/remote-desktop-client on home mac
and in both cases - proper configuration.
anyway you need properly configured tunneling thru workplace firewall, so some assistance from admin.

Dealing with multiples windows within a session (servlets & JSPs)

Hi,
How can I show multiple windows during a session and avoid terminating the current session when one of those windows is closed?
I have a main window through which the client navigates from page to page using servlets and JSPs. But if he opens the help window (via a <a href ... target="_blank"> and then closes the help window, the session is lost and the server doesn't recognizes the client anymore and creates a new session.
Can someone help?

Remote client copy fails.

Remote client copy fails.
The error message and info is given below. Help me to proceed.
Client copy
The client copy you started has terminated
Client Copy could not start because of Repository differences
Diagnosis
The table definitions differ between the systems. These differences mean that a copy of the data can cause a data loss and system inconsistencies. Differences occur when further developments were not transported or were copied between different maintenance levels.
Procedure
Transport all the developments of table structures between the systems using the Transport Organizer and bring your system to the same development level.
It is observed that some tables are missing in the target system. How do I copy the table structures to the target system?
Thanks in advance

Hello Ashraf,
There are repository differences between you source and traget system.
If you want to get the list of repository differences, then run a RFC check before you execute remote clinet copy.
You have to then remove these repository differences before you start with the remote client copy.
to remove the difference you have to:
"Transport all the developments of table structures between the systems using the Transport Organizer and bring your system to the same development level" as mentioned above
I would recommend you to go for Export / Import rather than Remote client copy.
There are several advantages of export import method over remote clinet copy

How do I connect multiple telnet clients to a telnet server in LabVIEW?

Good afternoon,
I'm writing a telnet server in LabView 6.1 that needs to handle multiple clients. To do this, I modified the "viserver\runvi.llb" example to use the telnet VI's from the Internet Toolkit instead of the TCP VI's. Then I changed the Open VI Reference to point to my telnet handler. Right now my handler just echoes the characters received from the client.
My software works ok for the first connection. After the server accepts two or more connections, characters typed in one client get echoed to all clients. In addition, only one client will accept characters at a time. The client accepting input changes randomly every few seconds as characters are entered.
Has anyon
e gotten the telnet VI's to run in parallel? Not sure if they are thread-safe or not. If you have some experience with this, I have attached my llb if you think you can help.
Thanks!

I don't think there's a problem with the TCP/connection portion of things. My feeling is that the problem is lurking somewhere in the timing of the application, or in the way LabVIEW task scheduling/multitasking is working compared to the way you expect it to work.
For instance, I'm wondering why you stuck with 25 seconds (25000 ms) as the timeout value for the Telnet Read in Telnet Handler.vi. I assume you're expecting LabVIEW to quickly "sleep" that while loop and move on to check on the while loops of any other Telnet Handler.vi instances that might have been spawned as a result of connection requests from other remote clients.
Instead, it seems to me (on my system, anyway, with three simultaneous connections active) that LabVIEW is not cyc
ling through the other Telnet Handler.vi instances as you expect, but is only getting to them to read a byte at a time each time the main loop iterates in response to a byte appearing from the first of the three remote clients.
If you change the Telnet Read timeout to 50 ms instead, the behavior is closer to what you might expect, but still not perfect.
Because timing/threading/scheduling is a complicated subject in LabVIEW, I'm going to give LabVIEW the benefit of the doubt and assume it's operating as designed. Maybe someone else can provide more insight into what's happening in this particular case, and whether reentrancy or something else is affecting things.
One option I would consider if I were in your shoes: program a simpler version of things that mimics Date Server.vi and cycles through a queue of connections to service them without relying on spawning new reentrant instances of a handler VI.
I realize that your version of things (along with the reentrancy example
that ships with LabVIEW) is expressly intended to handle this daemon-style situation, but simpler may be better for the purposes of debugging and development ease.
My two cents,

Send message to client before session invalidated

i am using jsp and java servlet tech. for my web application.
my problem is :
i want to send a message to client before session invalidated.
please help me to find the best way to solve my problem.

You can detect session termination by putting an object in the session attributes which implements HttpSessionBindingListener. What you can't do is send a message to a client, basically because all http transactions are initiated by the client. The only way I can see you could do this is to put an applet on your web pages which periodically consults the server concerning the session state.
Then the problem is that there's no obvious way of determining if the session is about to timeout, only whether it has or not. Your applet couldn't return the session cookie (as such) because that would reset the session timeout and the session would never expire. If you could obtain the session without reseting the expiry (perhaps from SessionContext though that's depracated) you could look at getLastAccessedTime() and getMaxInactiveInterval, but I don't know that this can be done. You can't even count, on some systems, on the session remaining in memory.
If you really need to do this you may need to consider implementing sessions for yourself. I've done this for non-webapp based logins and it's not too hard.
