Server / Client connection
Hi guys i want to know that what is the process of client server connect
i install database 10g in server version (10.2.0.1.0) and i also download same client version my tns names.ora file is
+# tnsnames.ora Network Configuration File: D:\oracle\product\10.2.0\db_3\network\admin\tnsnames.ora+
+# Generated by Oracle configuration tools.+
LIVE =
+(DESCRIPTION =+
+(ADDRESS_LIST =+
+(ADDRESS = (PROTOCOL = TCP)(HOST = COMPUTER1)(PORT = 1521))+
+)+
+(CONNECT_DATA =+
+(SERVICE_NAME = live.ss64.com)+
+)+
+)+
So how can i connect with client if i install same version of client in client system ?
What is tns_admin role in client system?
What is listneer role in client system?
Please send some detail
Regards

I would recommend you read thru the excellent documentation for an understanding of these concepts - http://download.oracle.com/docs/cd/B19306_01/server.102/b14220/dist_pro.htm#i4059

Server/Client connection using an actionListener
Hey guys,
New to this board, so hopefully I can be of assistance :)
What I am currently working on is a networked Monopoly game. My part of the assignment is to create a simple game lobby (just GUI based, buttons, action listeners, etc) where players can create games and join games already created.
What I have is this. When a player clicks on the "Create Game" button, an anonomus inner action listener will detect the push and create a hosted game (Server side connection). When a player clicks on the newly created game, they will be a joined player (Client side connection).
The problem is this, keep in mind that I have created a very, very simple server/client chat to test this out. When a Socket is created for the clients to connect to upon the Create Game button push, my program essentially just hangs. Nothing happens at all.
Here are the 3 classes I used. I understand this is probably not the most efficient way to post, but this is the only way you can see what I exactly have. I took out all my GUI stuff to make it easier to follow (if you want me to post full classes I can):
Thanks for all the help!

Thanks for the response
I think I understand what you are saying, I just want to make sure I get it fully. I need to create a separate thread that runs just my connection process to make sure that the processes actually occur? If so, how would I go about doing this?

AP server client connection on SoH with System Replication
Hi Experts
I'm using Business Suite on HANA with System Replication for HA purpose.
As client access from ABAP server to HANA DB, I use DNS redirection.
When I takeover to secondary system & after DNS redirection, the working process of user client (SAPGUI) remains for a while until rdisp/max_wprun_time's limit.
(means it not automatically restart process.)
After creating new session from SAPGUI, it works correctly.
Is this normal procedure?
If it automatically re-connect with new DB connection, it would be useful.

Oracle server - client connection question
This is my problem:
Server A : oracle server (behind the firewall)
Server B: the bridge server
Server C: my application is on who need to connect to the database on A
C can not connect to A directly. But it can connect to B. What are my options? If I install an oracle client on B, then can I connect to the client who will connect to the db server on A? Do I need to install a client on C as well? does it work?
Thanks,
Chauuser626162 wrote:
So I need to install the oracle client on C and the Oracle Connection Manager on server B? Would you point me to the document on how to do this?Correct. A good place to start is probably the [Configuring and Administering Oracle Connection Manager|http://download.oracle.com/docs/cd/B19306_01/network.102/b14212/cman.htm#NETAG011] chapter in the Net Services Administrator's Guide.

Remote access VPN clients connected to Internet from VPN
Greetings,
I need to let remote VPN clients to connect to Internet from the same ASA VPN server
" client connects to ASA through VPN tunnel from outside interface then access Internet from the same ASA from outside interface again
thanksyou'll need to configure 'same-security-traffic permit intra-interface' on the ASA .
Also, need to setup the corresponding nat statements for your clients pool range.
i.e.
global (outside) 1 interface
nat (outside) 1 access-list anyconnectacl
where anyconnectacl is the pool for your clients:
access-list anyconnectacl permit ip 172.16.1.0 255.255.255.0 any -
regarding mountain lion server: clients experience intermittent service connections. the server system log has the following error- Client handshake failed (6):113: Server not accepting client connections. any suggestions would be greatly appreciated - thank you
Hi Jason
I was getting the same behavior after Apple support had me delete some plist files to get Airplay going. I was also getting the following error:
the error occurred while processing a command of type 'writesettings' in the plug-in 'server vpn'
I went into ~/Library/Preferences/ and /Library/Preferences/ and deleted every plist contating the word server. I had to re-set up my server (meaning walk through some intial steps) but all of my settings were still there after that and everything started working again.
Just a thought, obviously try at your own risk but it worked for me.

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.

nullHi Hasan,
Firstly, please make sure that the software is compatible with the Windows Server 2012. Have you updated this software to the latest version?
Secondly, please check if the software is listening on the proper port. To verify this, please use the command below:
netstat -an
Also, please disable the firewall and try again.
Best regards.

How to get clients connected in WMS on windows server 2008 with c# coding
Sorry to bother anyone about this question.
Can anyone knows how to retrieve amount of client connection to Windows Media Server in real time same as WMS does on server console by c# programming ?
I got logfiles of WMS in system32 directory for details but it must be off-line of all connections which will able to get those informations for doing anything,but in this case I want real time client connection
at online when a client connects to WMS that I will get amout of that client also.
I have tried to search Windows Media Service SDK to develop this on my Windows 7 OS,but I did not find that really.
Can anyone knows this,please ?
Regards,
BigBermHi SYaGCi,
Denis is right this is actually documented in the Supported Platforms Documentation:
"Windows 7 and Windows Server 2008 R2 are new platform support additions in Service Pack 3 which are only available for support on the SP3 full release install of SAP BusinessObjects Enterprise. The SP3 patch only release of SAP BusinessObjects Enterprise does not provide support for these two new platforms."
Kind regards,

Non-Domain joined clients connect to server initially but cannot connect via Launchpad
Running SBS 2011 Essentials in a small office. Running XP/Vista/7 clients. All working fine until we swapped routers. Old router died, new router was installed.
Now all domain-joined PC's connect as normal, but all NON-Domain-Joined PC's cannot access the server via the launchpad. I get the "The server appears to be offline. Do you want to sign in to offline mode?" box.
Tried removing PC from the SBS Dashboard, uninstalling the connector from the client, restarting client, and reinstalling the connector. I can install the connector (using
http://<server ip>/connect , but not http://<servername>/connect
). Connector installs but it still tells me the server is offline when trying to use dashboard or launchpad on the client.
Note: I can add a network location or Map a network drive to ther server after inputting my network password from Windows.
Any Services to check? Firewalls exceptions to ensure? Advice?
EDIT: Dashboard on Server shows Client, sometimes as online, sometimes as offline.Sounds like name resolution issue to me.
Are all your clients set to use the IP of the Essentials Server for their primary DNS?

What privileges for the DB account used by client connect to server?
Hello, After I installed the SBO server packages, I found that it must set DB account in the client side.
I had tried 'sa' account, it works. but I thought we should not leave the super account in each client side.
So I want to know what privileges should be assiged to the account in SQL Server?
Or somewhere already have documents to say how to build up the client account.
thanks.Hi,

How to set proxy for client-server socket connection?
Hi,
I'm using the code found on the following page to create a client (mobile) to server (pc) connection and send a text message.
http://javafaq.nu/java-example-code-503.html
This works with mobile operators without proxy, but does nothing when the operator uses a proxy. The question is, exactly how to set the proxy and port values for using that code.
Any help is greatly appreciated, thanks,It's part of the cellular settings, and is usually set up by your 3G provider. You can't choose your own proxy server

Hello there
I have a problem with my windows media player while using server and client connection by using TCP/IP connection. So when I play a video using Windows Media Player in LabVIew there isn't any sound come out but when I'm playing a video by a Windows Media Player only the sound will come out. Can you help me solve this problem?
I also upload the vi as the reference.
The username for the client is ihsanhaikalz and the password is ganteng
Thanks

Client Remote.vi 746 KB
Server Remote.vi 1433 KBHi ican,
I was looking at your VI's but I cannot seem to pinpoint exactly where you are using Windows Media Player. In order to more quickly assist you, could you please recreate this issue more concisely in a smaller set of VIs. Also, were you able to get sound when you did not use the TCP/IP connection and simply played the files in LabVIEW?
I noticed in a few places that you were using the Play Sound File.VI from the Graphics and Sounds palette. Is that what you are refering to? I noticed there that the file path that you have designated for the song is simply the song title. Instead, this should be a path to where the song is located on your computer.
Also, if you are planning on using Windows Media Player, have you considered using the ActiveX commands for Windows Media Player? Here are a few examples if you are unfamiliar with this functionality.
Example 1 and Example 2.
I hope this helps!
