Loss of Client/Server Connection through

Hello,
i do have a big problem. We loos connection after 10 minutes between oracle-client and server.
It is install a firewall between client and server and the firewall will close this ports after 10 minutes, witch dont user it for the datatransfer. I will hold this connection for the longer time, because on the server runs jobs for a longer time as 10 minutes. When i will try to connect from the oracle-client to the oracle-server, then i get problem with this jobs on a server, because it will start the same job which to run on a server since few minutes.
Can anyone help me, please.
Thanks Frank

Thanks for the answere.
i had find out, how can i hold the connection.
Enable "Dead Connection Detection" i the sqlnet.ora. Set sqlnet.oxpire_time = 10 (10 Minutes is default.)
As soon as the Firewall will clost the connection in 10 Minutes, then set less as 10 Minutes. Use 9 Minutes or less........
Important: Reset the Oraclelistener unter "Services" !!!!

BPC server connectivity through Public IP

Hi,
We want to connect remotely to BPC server over internet. Though server has been put over public IP(through some internal server), while connecting it throws an error message. We are connecting through default port as well as secure port. Is there any port needed to be opened on this server so that we can access BPC application remotely. Port number currently opened is 3200.
If anyone has done this remote connectivity with BPC earlier please share your experience?
Thanks,
Raman

Thanks Ethan, we are able to connect remotely on port number 80, however we need to change this port number to some other port number due to potential security threat. To accomplish this I changed port number in the IIS to 90 as well as the Web and ServerManager configuration files.
I followed the folowing instructions as per install guide:
To change the port number for the Web configuration file, open the Web.config file: <Server
install folder>\Websrvr\web\Web.config, and change the value of the port number
in the AppServer_URL key.
To change the port number for the Server Manager configuration file, open the <Server
install folder>\Server Managment\OsoftInstall.xml file, and change the value of the
port number in the <port><PORT></port> key.
I did exactly as per the instructions above but not able to connect to BPC even in the local network. I am not sure what is going wrong. Addtionally when I launch BPC serverManager now I get the error tHAT USER DOESN'T HAVE sYSaDMIN PREVILEGE.
Appreciate your help on this issue.
Thanks,
Raman

Integrating DOS/client server apps through portal

Is there any partners out their that have developed any portlets that will integrate legacy client server or DOS through the portlet in a Citrix NFuse fashion?
There seems to be a few competitive portal providers out their who claim that this can be done. OBTree does this via Java wrapped emulation software which can be integrated over the web.
This would be very useful for legacy integration into one place without rewriting a front end etc.
Any ideas or recommendations?

Any one got idea how to resolve this problem. We are facing this problem with applet based applications. Pleae let me know if any one know how to write netlet rules to make this app. work through portal.

Client/Server connection between unix machines

Hi,
I have a problem about connectivity.
When I try connect to a dsn in a server from a machine with client TimesTen software installed.
Details:
CLIENT1: TimesTen Release 7.0.5.0.0 (32 bit Solaris/x86) (tt705) 2008-04-04T00:06:33Z
SERVER1: TimesTen Release 7.0.3.0.0 (32 bit Solaris) (tt703:17000) 2007-09-12T05:45:43Z
SERVER2: TimesTen Release 7.0.3.1.0 (32 bit Solaris) (tt703:17000) 2007-10-30T22:52:42Z
SERVER3: TimesTen Release 7.0.3.1.0 (32 bit Solaris) (smpcluster:15000) 2007-10-30T22:52:42Z
connections CLIENT1 --> SERVER1 ==> OK
connections CLIENT1 --> SERVER2 ==> KO
connections CLIENT1 --> SERVER3 ==> KO
user@CLIENT1 > ttIsqlcs ngincz_prod_s3scp03
Copyright (c) 1996-2008, Oracle. All rights reserved.
Type ? or "help" for help, type "exit" to quit ttIsql.
All commands must end with a semicolon character.
connect "DSN=ngincz_prod_s3scp03";
S1000: Protocol mismatch; client protocol: 32, server protocol: 32
S1010: Function sequence error
The command failed.
Done.
In error log file server we can see these messages:
11:44:50.42 Err : SRV: 14749: EventID=37| Client version 32 is not supported, the current server version is 31. Contact TimesTen support for instructions on how to download new versions of TimesTen Client/Server
11:44:50.42 Err : SRV: 14749: EventID=68| Failed to read request from client. Closing connection without reply.
Any idea about cause/solution ??

To enable cross release client/server operation you need to add the line
-insecure-backwards-compat
to the ttendaemon.options file located in <tt_install_dir>/info on the system that hosts the datastores that you wish to connect to. For this to take effect you must restart the main daemon so you will need to shutdown all the datastores before doing this!
This is documented in the TimesTen Installation Guide and the Timesten operations Guide.

Can anyone please help me how to connect to my Office Server from my home place through internet. What are changes required in TNSNAMES.ORA file, SQLNET.ORA.

Hi, Is it the database server available from outside office??, Does server has a public interface? Do you have access to server through simple TCP connection from your home??
Luck.
Have a good day.

What is the best way to detect loss of OPC Server connection when using DSC Tags?

I'm using the DSC Module on a new project and I'm pretty impressed so far. The HMI Wizard has saved me quite a bit of time.
My application is configured where the DSC Tags are connected to remote OPC Server Tags.
The issue I'm having is that I cannot detect a loss of the OPC Server when the application is running. Read's of the front panel controls/indicators still return values and the little "connection" icon next them is still green. Even if the connection icon turned red it wouldn't help since the Front Panel is not visible when the main application is running. It is a Sub-VI that's in charge of OPC Data Interfacing. The rest of the application uses the data from the OPC Sub-
VI.
I cannot effect a change on the OPC Servers, so I need a method of detection when the Server is lost on my end.
Any ideas on the best way to do this?
Thanks,
Jim

Hi Jim,
Ideally, error-reporting and -handling should be the way to handle this. However, if errors are not reported/handled as is sometimes the case with OPC, a quick-n-dirty way to do this would be to check for a "heartbeat" signal from your OPC Server. This could be a boolean tag which toggles On and Off (or a counter ticking). You then read this Tag in DSC in a slow loop using the Read Tag VI (not the front-panel control). And keep track of the Changed? output from this Read Tag VI.
As long as the 'Changed?' output is true, you are receieving data from the OPC Server, and hence it's alive. You may add some deadband logic to wait for a specific period of time before declaring the Server's really dead!
Hope this helps,
K

Client/Server connection question

I am trying to understand some basic connectivity tricks between Client and Server.
I saw my friend doing stuffs like, query google.com with certain keywords, and present the return results on another webpage or program using jsp. I have no idea how he did that, and I wonder if anyone here is familiar with such tricks.
Edited by: ttback on Dec 3, 2007 4:06 PM

To access a specific search thing you can use URL and URLConnection classes like:
String search_query; //input it...
URL url = new URL("http://www.google.com/search?hl=en&q=" + search_query + "&btnG=Google+Search");
URLConnection urlc = url.openConnection();
//read from urlc
//print the result...

Help please with Client Server Connection

I have created a server and a client but I have no clue how to execute both on my computer. Can anyone please help me??

Problem solved!
It took:-
4 day's of discussing this issue with BT though the usual automated telephone answering palava and talking to at least 4 different support team people, all from/in another country with different understanding, communication and training levels.
Running numerous Line tests
Trying 3 different routers (including having to find the old ones in the shed!)
Checking speeds on an iMac, Macbook Pro, iPad and even a Playstation
Methodically checking the settings of the router detail by detail
Running other speed testers
Changing cables
etc. etc...
I finally realised that whilst my connection speed was 8mbps, BT had set an IP Profile for the line of 2mbps. This is not alway's obvious when you run their speedtester as that site doesn't alway's show it to you!
Having rung them again and told them of my discovery I now have between 6 & 7mbps and can hopefully watch steaming video without interuption.
An awful and unneccessary experience - Well done BT!

Calling functions over client server connection

i am currently sending an object between client and server that contains getters that have string variables that are evaluated by a large if statement in the reciever. i was wondering if it is possible to do this a simpler way rather than having a large if statement for all fo the possibilities that are contained in the object.getAction.
ie:
client sends object to server where getAction() = count
server receives object and evaluates the getAction() in a large if statement like so
if object.getAction()=="hi"
hi();
else if object.getAction()=="hello"
that();
else if object.getAction()=="count"
count();
else if object.getAction()=="multiply"
multiply();
is there a simpler and quicker way to do this? i have thought of ways that would just allow a direct calling of a function on the server or client side but i don't see how it would be possible.
something like this...
String function = object.getAction()
function(); -- where function is the string variable it receives from getAtion();
I know it is not possible to call a function from a variable, but that was my idea. any input or ideas wold be helpful.

If your server has an array of predefined Runnable objects and the return value of the getAction() method is an int, then
new Thread(rarray[object.getAction()]).start();In Java, only closure-like object is Runnable.

Client connecting through firewall

Hi
          We have two clustered servers.Our client is connecting through
          firewall NAT. When iam connect to first server the response is very slow and
          at the same time clustering is not working.If i stop the second server the
          response fast .
          The same configaration is working fine when my client is local.
          Can you explain the reason for this problem ?
          Presently iam using weblogic 6.1 version.
          Thank you


OK I spoke too soon. The user looked like it was working but it was working because it matched another IAS policy further down the list. It seems as though the PIX refuses to use ms-chap of any sort. If I include the authentication type in the VPN policy conditions as ms-chap, it skips the VPN policy I am using to authenticate this. If I remove it, then it gives an invalid authentication type as if whatever the PIX is sending the IAS server does not understand as ms-chap.
It seems like the PIX authentication is totally wrong for use with IAS. What else do I need to add to this configuration to gewt it to work with ms-chap of any kind? I really don't get it.

Publishing .fla project including client - server socket connection

Hi,
I have designed with Adobe Flash Professional CS5 a .fla project that integrates a client - server connection.
After publishing it, I have the following issue:
- when running the generated .exe file for Windows, then the connection to the server works perfectly
- but when I am running the published .html file, then nothing is sent to the server.
I have tried to change the Publish Settings.
When setting the Local Playback Security in Flash menu to "Access network only" instead of "Access local files only" then the last packet that was send using the .exe file is resent once and that's all (the html client does not receive the response from the server and the next connection attemps generate data transfer).
I guess I have to change some security settings somewhere but I didn't find which.
Does anybody have a hint ?
Thanks.

Hi again,
I was finally able to solve the issue.
I did not get any error message when using firefox, but using iExplorer provided me this error:
"Local-with-filesystem SWF files are not permitted to use sockets"
Googling did then allow me to find the solution here:
http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04.htm l
The local locations on which I store my html page during the development has to be added to the trusted locations in the global security settings.
Hope it will help some other people.
Best regards

Client Server mode for time ten connection

Hi, I am new to Times Ten and got a question for running TimesTen in Client Server Mode. When it is running in Client/Server mode:
Does the database just run like a regular remote database ?
Is there security for the remote application, such as userid/password ?
Is there any limitation on number of remote connection can concurrently connect to the DB ?
Does it use the JDBC or it has to be the native library ?
Thank you for your help
Henry

Hi,
With regard to your questions regarding TimesTen client/server mode:
1. Does the database just run like a regular remote database ?
I'm not sure exactly what you are getting at here but yes, I would say that it runs like any other c/s database. If you can be more specific in your question then I can give a more precise answer.
2. Is there security for the remote application, such as userid/password ?
If the TimesTen instance to which you are connecting was installed with Access Control enabled then yes, normal userid/password security applies. The client application must provide a valid TimesTen userid and password in order to establish a connection.
3. Is there any limitation on number of remote connection can concurrently connect to the DB ?
Subject to O/S resource limitations, a single instance of TimesTen (i.e. the TT server) supports a maximum of 9,999 concurrent client/server connections. Each individual datastore supports a maximum of 2047 concurrent connections (direct and client/server).
4. Does it use the JDBC or it has to be the native library ?
The TimesTen JDBC driver supports both direct modde and client/server. The TimesTen ODBC driver is provided in both direct mode and client/server versions. The JDBC driver uses the ODBC driver (it is a type 2 JDBC driver) and so the client machine requires a TimesTen client installation to use either ODBC or JDBC to access a remote datastore.
