Allow remote client access
Sorry if this has already been posted. I recently installed 3.1.2 on 10g xe and I am unable to find where I can allow access by remote clients. I remember on 2.1 that there was a section that allowed you to manage http-access. I've logged in as ADMIN and can't find it anywhere.
I needed to allow login page access by browser from another machine on the network. Setting this in sqlplus allowed me to enable that. To bring up the login page for the remote machine I use http://xxx.xxx.x.xxx:8080/apex as the url. Where xxx.xxx.x.xxx = ip address where APEX and 10g xe instance is running.

Issues with remote client accessing EJB3
Hi folks,
I tested Weblogic 10.3 these days and had some trouble to access a stateless session bean (EJB3) via a remote Java client. My development system is Windows Vista 32bit.
First, Weblogic doesn't like blanks in folder names! The Test Client throws an exception complaining that the business interface is not found:
Exception in thread "Main Thread" java.lang.AssertionError: java.lang.ClassNotFoundException: ejb3session.Trader

In fact, the compiled class file of the business interface is located on the file system in a path that contains a blank. Debugging session shows that the internal weblogic class RemoteBusinessIntfGenerator fails to open the class file because of a wrong used URL file reference. If the path contains no blank, everything works fine. This is obviously a bug!
Second, generics don't work in the business interface. As soon as I insert a generic return type or method parameter, I get an exception at runtime, no matter if the actually called method is generic or not:
java.lang.NullPointerException

Third problem is already known by Oracle (CR373734): when using JPA and serializing entities to the remote client, serialization fails until you implement a writeObject() method in every entity.
What is your experience concerning these issues? For my opinion quite severe bugs...
Cheers, ThomasBut most of the O/S like Linux ,Solaries does not allow blankspaces in the classpath. Only the O/S that does allow is Windows. and there are a lot of issues regarding the spaces in the classpath.
If a blank in the classpath exist in the admin console as a remote start argument for a managed node, a patch exist.its CR375981.
But for the above case 808498 (blank for remote client classpath) Engineering did not given any patch and asked to go with the work around ie not to use a blank in the classpath.
Thanks !! -
Remote client accessing ejb - question
This may be a very simplistic question, but here goes -
scenario: I have a J2EE application running on a server Y with session beans/entity beans.
I need a remote client on machine X to access EJB objects on Y.
I have set the initial conext with INITIAL_CONTEXT_FACTORY, PROVIDER_URL etc...
But, in order to narrow the reference of the object returned by lookup() method, I need to instantiate the Home object of my session (or entity) bean ...
here's my problem: How do I instantiate EJBHomeInterface or EJBRemoteInterface, when they do not exist on the remote client machine?? (does this have something to do with the stub??)
THANKS!This answer assumes you're using Weblogic, although most any other EJB container has a facility for this. Basically you need to distribute a client jar file with the client. This client jar is created during the EJB compile/deployment process and creates a jar separate from the normal jar file associated with your deployment. This jar file contains the class stubs you need to call for and use EJB's on a remote client.
I hope this makes some sense.

How do you allow remote iPad access to our internal corporate network?
We have a group of sales guys who are going to be getting iPads (if we can make this functionality work.) We have an internal network where we have several hundred files stored that each sales guy accesses on a daily basis. While traveling, we are wanting the salesmen to be able to use an iPad to access those files stored on our internal network (these are basically MS Word files and MS Excel files.)
I understand this is easy when setting up a laptop to connect remotely. Is it easily do-able with an iPad?
Any thoughts??
Thanks,
DominicSo something like Goodreader or Dropbox would work...if the files are *.doc's you could use Quick Office Pro HD to edit them. An iPad probably isn't the place to do complicated edits, however...either of these apps will allow a file local to the iOS device to be stored, then sent to another app such as Quick Office Pro HD...or you could also have the files stored in an email folder in say, Outlook, and then have that folder sync to the iOS device OTA with the iOS Exchange client...

What is the trick to setting up my OS X Panther system, as I had in OS 9, where my iMac would answer the modem line? Previously this setting was under "Remote Access">Answering and you could select answer, provide user name and password. I want to be able to remotely access my computer's files over the telephone line through a modem.
I have not found this information anywhere.
TIAPeter:
If you go to Finder -> Help Menu -> Mac Help and type in Remote Access you may come up with what you want. e.g. Here is something I found (albeit in Tiger):Allowing remote terminal access to your computer
If you allow remote login, you can use SSH (Secure Shell) to log in to your computer from another location.
You can't use Telnet to log in to the computer.
Open System Preferences and click Sharing.
Click Services and select the Remote Login checkbox. Selecting Remote Login also also enables the secure FTP (sftp) service.
Now you can use an SSH client to log in from another computer.
For example, if your user name is steve and your computer's IP address is 10.1.2.33, you can open Terminal on another Mac OS X computer and type:
ssh -l steve 10.1.2.33
Type "man ssh" at a Terminal shell prompt for more information.

J2EE Tutorial With Remote Client
Where can I find a J2EE tutorial that demonstrates a remote client accessing an EJB? The Sun tutorial are all localized examples. Does a remote client have to run on a J2EE server?
Thanks,
-RayRemote Clients do not have to run in a J2EE server. All you need is the j2ee.jar and your app server's required runtime jar file(s) e.g oracle9iAS(oc4j.jar) and the .properties files.
Let me know if you need any more information. -
Enabling remote desktop access to a simple windows 2012 datacenter edition server
Hi,
I am a complete noob to server administration. I installed a windows 2012 server initially as a workgroup. All i need is to enable a user to remotely access my server(using remote desktop). The firewall that I use is Gibraltar.
I read that to enable remote desktop services my server has to be part of a domain. So i promoted my server to a domain name controller. Using active directoty I added a user to the domain. I also read that to make remote desktop more secure, I have to request
the user to login through a VPN.
Now here is where I am completely lost. Do i really need to move my server to a domain, if the user just wants access to this server and nothing else? Should i restrict remote desktop access only through VPN
and if so, how can i do that? Further, the server dashboard gives me notifications about 'remote desktop licensing' not configured. We got the software as a campus licensing and I am not sure how to configure the remote license server. Any opinions are highly
appreciated.If you're just trying to setup this to allow administration access then I don't believe you need it to be a member of a domain. There's a difference between allowing remote desktop access for administration, and setting up full terminal services access for
multiple users. The latter requires a lot more work and licensing unlike the former.
To simply allow admin access, open an explorer window and right click on Computer, then select properties. In the System window that appears, click Remote settings on the left. Now in the bottom half of the window select "Allow remote connections to this
computer" and leave the option requiring NLA in place. Click Select Users..., you'll see that the administrator user already has permissions to connect, so if you're only planning to connect with that then you're finished, otherwise find those users you
want to grant access. -
I am using a window 7 professional service pack 1 and I purchase REMOTE DESKTOP SERVICES CLIENT ACCESS LICENSES FOR MICROSOFT WINDOWS SERVER 2012 STANDARD AND DATACENTER. but the seller did not send me any installation CD or instruction
on how to use it.
Please how can I use it on my window 7 professional service pack 1.
Thank you.Though Bill is absolutely correct for most CALs, Remote Desktop Services does have its own special licensing server. I haven't installed one on 2012, yet, but here is a step-by-step guide for 2008.

Here is a lab guide for 2012 -
http://technet.microsoft.com/en-us/library/jj134160.aspx
But, the explanation of your environment begs the question - what are you trying to do? You say you have a desktop OS and you are talking about Windows Server products. In that light, your question does not make a lot of sense.

Prohibit full remote desktop access and allow remoteapp
Hi all,
How to allow remoteapp only while prohibiting full remote desktop access except for some users?
ThanksI am Microsoft Tech with Platforms Core , I came across this thread rather recently. So as a Christmas surprise it can be achieved rather simply.Please follow following steps...
1. Please navigate to HKLM\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-TCP
2. Change the value of port to anything from 3389.
3. Also change it in remote app manager in RD Session Host server RDP Port to the port you have changed to in registry.
4.Please note it has to be done on all session hosts,redirectors and Connection brokers.
5. Now your remote app continues to work , however RDP done sans the exact port number will not work.
Please feel free to contact me on this.
Simple sweet and logical resolution. Cheers..Happy holidays :-) -
When I went to the Quicken site I was routed to a third party tech company that asked me to download a software that allowed them to access my computer for a remote session to fix my computer. Is that a scam? I did not do it but how do I get my Quicken 2007 to work with Mountain Lion?

VNC access to remote clients assigned address from vpnclient ip pool
Hi,
I was wondering if anyone knows if it is possible to vnc to remote vpn clients that are assigned an address from a client IP pool defined on the pix.
The remote clients are using cisco vpn client, the access-list is a dynamic acl downloaded from a tacacs server.
thanks.It is not possible to vnc to remote vpn clients that are assigned an address from a client IP pool defined on the pix

if possible??? how do we configure the mac mini to allow the clients to access both partitions...the client will only see the one we are logged into at the server???
You have to explicitly share directories on external/secondary volumes.
Use the Server admin app to configure file sharing, and select which directory/directories on the second drive you want to share, then they'll be available to clients. -
I would like to add a new Firewall 'Inbound Rule' to allow remote access by
SQL Server 2008.
SQL Server Management Studio shows two TCP/IP instances, both of which are Enabled.
One uses port 1433 and the other uses ‘TCP Dynamic Ports’.
In SQL Server, the server has ‘Allow remote connections to this server’ checked.
My Firewall allows port 1433 for the one TCP/IP instance.
Since the other instance is dynamic, I would like to add a new
Firewall 'Inbound Rule' to allow the SQL Server executable to run.
I’ve read that the SQL Server executable is commonly named SQLSERVR.EXE, but there is no such file on my laptop.
I’m assuming the executable that needs to be added to the Firewall 'Inbound Rule'
is SQLCMD.EXE (in the path C:\Program Files\Microsoft SQL Server\100\Tools\Binn).
Can anyone please confirm this? (I'm running Windows 7). Thanks.Hi Bontrager,
Firstly, please run
Discovery Report to the detect the existing SQL Server 2008 instance. If SQL Server 2008 is installed properly on your machine, the sqlservr.exe should exists in C:\Program Files\Microsoft SQL Server\MSSQL10.<instance_name>\MSSQL\Binn.
Secondly, if SQL Server 2008 is configured to use dynamic port, it is difficult to configure the firewall to enable access to the correct port number because the port selected might change every time that the Database Engine is started.
Therefore, if a firewall is used, please reconfigure the SQL Server 2008 to use the static TCP port by using SQL Server 2008 Configuration Manager.
For more information, please review this
article. After that, you can add the port number in firewall inbound rule.
Thirdly, if you want to connect to SQL Server 2008 from outside the firewall by instance name, SQL Server Browser should be turned on and you'll have to allow the SQL Server Browser through the firewall, which is UDP port 1434.

Can't connect to computer in remote web access
I am running sbs 2011 essentials and have been able to remotely log in to the remote web access page. Once I get there I can see all the shared folders on the server (and access them) and I can also see the computers available for access (my computer
and the server). I can access the server dashboard by logging in as the server administrator (by using domain\admin) and then in a second login as a user (domain\user "with administrative rights"). However, when I go to logon to the client
computer, I receive the error "Remote Desktop cannot find the computer "client". This might mean that client doesn't belong to the specified network. Verify the computer name and network that you are trying to connect to."
Do I have a DNS problem since I can connect to the SBS 2011 Essentials server?Hi,
Are you facing issues with all the client machine connection? On the workstations make sure Remote Desktop feature is enabled
Make sure windows firewall service is enabled and inbound rule for allow RDP is enabled.
