Connecting to the Oracle Server

I want to write a small application which will connect to the Oracle Server (10g).
I have downloaded the ojdbc14.jar from the Oracle site. What should I do with it now ?
Someone told me that you have to add it to classpath. Which classpath ? the systems ? or in the project itself ?
and how will I be able to connect to it ? I mean which api(s) should I use.
Can anyone help me please

It should be in the classpath of your application that connects to DB.

Hi,

And one more question in the meanwhile i want to take Backup of one database which client as connected. Is it get any problem to the client machine which is accessing the server. And How to take the backup from the server machine. Any commands to process.
Thank u...!

Hi there.
If You run
select count(*) from v$session where username is not null;you'll get the number of users connected to Oracle server,
and yes , you could do backup while users are connect to db you are backing up.
cheers

Fails to connect to the Oracle yum public server

Hello,
I would like to connect to the Oracle public yum server so I can install packages from the Oracle Linux via a yum client for my RHEL 5.4
I am trying to download and copy the appropriate yum configuration file in place, by running the following commands as root:
Oracle Linux 5
# cd /etc/yum.repos.d
# wget http://public-yum.oracle.com/public-yum-el5.repo

Retrying.
It disabled the Linux firewall by /etc/init.d/iptables stop but it still doesn't help.
Thank you.

You have DNS properly configured, but you need to double-check your default gateway and other settings to make sure you can connect to a server on the internet directly. If you need to use a proxy server to make connections, you will have to configure that as well.

Hi Thanks for the reply
I check check-box of proxy settings and restarted the jdeveloper and tried again but still it throws the same error? one doubt here...what all we need to include / exclude in our proxy settings...
and the I tried providing service name as both java and javatrial8477 but no luck i followed the same steps which are mentioned in the below document
Part 2: Deploying ADF Applications to Oracle Java Cloud
Do i need to do any other configuration? Or i can directly deploy my ear file to java service console rt instead of creating connection tot the server from IDE.

BAM Server stopped working - Cannot connect to the Oracle BAM services

Hi,
On logging into the OracleBAM page, I get Error 500 - Internal Server Error.
Caused by: java.lang.reflect.InvocationTargetException

How do I fix this? Help Please!
Also, is there a way to bring my BAM installation back to its vanilla state? Maybe run the Repository Creation Utility once more? Are there any files on the server that has to be cleaned?
Thanks

Hello SOA gurus,
We're getting the same error as well. Our's a Linux environment and we've configured 2 managed servers (soa_server and bam_server)
Log file for the bam_server throws up this error message periodically. Looks like the other server doesn't. Does this message pertain to only BAM server ? (I'm new to SOA suite).
Also, is this a show stopper ? I've seen the managed server going down at times and wasn't sure if it was due to this error. Don't know if this error can be ignored or need to fix.
Can someone help on how to fix this really soon please ?
Thanks

Insert data 32K into a column of type LONG using the oracle server side jdbc driver

Hi,
I need to insert data of more than 32k into a
column of type LONG.
I use the following code:
String s = "larger then 32K";
PreparedStatement pstmt = dbcon.prepareStatement(
"INSERT INTO TEST (LO) VALUES (?)");
pstmt.setCharacterStream(1, new StringReader(s), s.length());
pstmt.executeUpdate();
dbcon.commit();
If I use the "standard" oracle thin client driver from classes_12.zip ("jdbc:oracle:thin:@kn7:1521:kn7a") every thing is working fine. But if I use the oracle server side jdbc driver ("jdbc:default:connection:") I get the exception java.sql.SQLException:
Datasize larger then max. datasize for this type: oracle.jdbc.kprb.KprbDBStatement@50f4f46c
even if the string s exceeds a length of 32767 bytes.
I'm afraid it has something to do with the 32K limitation in PL/SQL but in fact we do not use any PL/SQL code in this case.
What can we do? Using LOB's is not an option because we have client software written in 3rd party 4gl language that is unable to handle LOB's.
Any idea would be appreciated.

Possible workaround for: Launch Debugger Error "Unable to connect to the RDS server"

I do not yet have a reproducible case for this. *Sometimes* ColdFusion Builder throws the "Unable to connect to the RDS server" error, when attempting to start a debug session against a remote server. However, "RDS Dataview" and "RDS Fileview" views correctly list the servers and their related data/file, and testing RDS connection result is "Test connection was successful". The workaround is:
1. Login to the ColdFusion Administrator
2. Navigate to "Debugger Settings" page (beneath "Debugging & Logging")
3. Click on "Stop Debugger Server" -or- "Restart Debugger Server"
4. Restart ColdFusion Application Server
Notes:
a) Step #3 must be done via ColdFusion Administrator, not via ColdFusion Admin API (stopLineDebugger()|restartLineDebugger())
b) Step #4 can be done via ColdFusion Administrator -or- ColdFusion Builder
c) Note that there is a CF9 Release Note for Bug #78488: "When a server having "Windows service option" ENABLED is added as a remote server, then Start-Stop-Restart operation cannot be done on it." However, I've found that "Restarting" a remote server, that is running as a Windows service, is possible in ColdFusion Builder (at least this is so on standalone developer edition). Like Bug #78488 says, I am unable to "Stop|Start" a remote server that is running as a Windows service. I'm just mentioning all of this, due to my suggestion in "b", that CF can also be restarted via ColdFusion Builder.
It is interesting that attempts to stop|restart the debugger server, via CF Admin API, do not resolve the issue. So, it seems that the "Stop Debugger Server" and "Restart Debugger Server" buttons, in CF Admin, are doing more than calling the corresponding CF Admin API methods.
Attached is an image of the error.
Just posting all of this as an FYI, in case it helps anyone.
Thanks!,
-Aaron Neff
(OH.. I'm unable to attach images at this time *DOH!* ..well, I'll try to remember to update this post w/ the image, once I see that attachments are allowed.)
I'll try to describe the error message window:
- It is 494x452 pixels
- Title of the window is "Error occurred while launching the Debugger"
- Body content of the window is as follows:
Unable to connect to the RDS server 'ServerNameHere'
Ensure that the server is currently running and that line debugging and RDS are enabled. You may also need to check your RDS connection settings in Eclipse to ensure that they are correct.
Error Message:
-1:Error connecting to JVM for debugging at localhost:5005. Could not attach to the VM at port 5005. You must specify this debugger port in the JVM settings of your application server, for example: -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005. You will also need to make sure that another debugger is not currently connected to the CF JVM at the same port (5005).

RWCLIENT (10g iDS) is installed on different machine.

On client I updated the rwnetwork.conf with OracleAS hostname and 14021.
What is wrong? Maybe I need to start Naming Service using OPMN for report server to register.

Not able to connect to the Oracle FTP Site.

I am unable to connect to the oracle ftp server.
ftp://oracle-ftp.oracle.com/dev_tools/patchsets/dev2k/Win95NT/d2kwutil/
I need to download the latest version of d2kwutil for forms 4.5.
The one with the WIN_API_SESSION call. I got a version for forms 6.0 but I need one for
forms 4.5 with d2kwut32.dll. Please let me know how to download this.
Any help is highly appreciated.
Thanks, Prabhu.

As you said I renamed d2kwut60.dll to d2kwut32.dll and I tried deporting the Forms ver 6 D2KWUTIL.PLL to Forms 4.5 D2KWUTIL.PLL .. but unfortunately it didn't work out. All I wanted was the WIN_API_SESSION for timeout on FORMS application (if kept idle) .. but it turned out I need to modify WIN_API and other functions to accomdate this new function .. and also I think since PL/SQL version is of lower version in 4.5 .. I am having compilation problems also.
Since I am unable to connect to the FTP site I would really appreciate if you have a version of D2KWUTIL.PLL for FORMS 4.5 with WIN_API_SESSION calls, which you could forward it to EMAIL ID : [email protected]
Thanks again for trying to help. Appreciate a lot.
Thanks, Prabhu.
