Does JDBC application need oracle client

We are going to wirte java application that going to use jdbc connection to Oracle database. The question is does this application require to have oracle client software to connect to Oracle?
Thanks.

No, I don't thinks so that you don't need a client for using JDBC

Does Admin server need Oracle Client

I have a setup where the admin server resides on a different server than the managed server. To setup a Data Source/connection pool does the admin server need to have the Oracle client setup for the data source to work which is targeted ONLY to the managed server.
Thanks

JohnHi John, no, and we recoomend highly that you use the oracle driver
in the thin mode, which needs no Oracle client installation at all.

Does JDBC Driver needs to be downloaded ?

Does JDBC Driver needs to be downloaded in order to be used?

Does JDBC Driver ....Huh?
JDBC is an inteface. It is part of the standard API that should come with most JVMs.
JDBC uses 'drivers' which are specific to the purpose at hand. The jdbc-odbc bridge driver comes with the Sun JVMs and has since at least version 1.1.4 (years ago.) Other drivers must be downloaded or acquired. For example the Oracle drivers can be downloaded from the Oracle site and they also come on the Oracle client install.

Does OID repository needs Oracle TEXT?

I remember in 10g I had to add this option, and don't remeber for what purpose. can't find any reference in 11.1.1.5 documentation what was it for?

If you are using a file datastore, then you load the file name into a varchar2 column and you do not load the whole file into a clob column. I have provided a demonstration below. In the demonstration below, the binarytree.txt file contains the word "test1" and the some_title.txt file contains the word "test2". The E drive contains a CD-RW disc, but the machine is my server. The drive and directory path that you use must be accessible to the server. You cannot use a drive on a client machine.

Access Oracle 9i from a Client Application without Oracle Client Install.

Is it possible to access an Oracle Database from a Client Application without having an oracle Client Installation ?
I want to write a program that connect to an Oracle Server. I use Borland C++. But my Programs only works with having the Client Oracle Software installed on the Client. Is there any way to realise this ?

The way that 99% of the people that want to do this manage is to write Java code that connects to the database via JDBC, using Oracle's thin JDBC driver.
If you absolutely have to use C++, you can purchase thin ODBC drivers from third parties (DataDirect for example) that will connect to the database without the Oracle client. I'm not aware of any thin, free ODBC drivers.

Do we need Oracle client?

Hi,
I have Java-JSP running on my local machine. I don't have Oracle client on my dektop. I am trying to connect to the database server using Oracle Drivers (classes12.jar). I am getting SqlException: Network Adapter Could not establish connection.
I am not sure whether I need to have Oracle Client installation? Does oracle drivers help us to talk to oracle database without client installed? Please let me know.

The client install would also allow you to use "tnsping" which determines connectivity to the oracle database.
The oracle data is installed on another computer correct? (If it is on your desktop then there is no point in not also having the Oracle client installed on your desktop.)

Acces Oracle DB, do i need oracle client locally

i have asp.net application which acces an Oracle DB throught ODP .net, my project includes the Oracle.DataAccess.dll, my test server has a oracle 10g client on it so i can access the DB fine, although the DB is on another server, wheni move my application to my live server and open my application (logon.aspx connects the DB ) i get this error :Unable to load DLL 'OraOps10.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
do i need to have an Oracle Client installation on my production server, can I not just access using ODP without having to have a client locally?

In your live web server, you will have to install ODP.NET using the OUI installer. The ODP.NET can be downloaded from "http://www.oracle.com/technology/software/tech/windows/odpnet/index.html". When you run the installer, you will have to select the ODP.NET component and install it.
Just GAC'ing Oracle.DataAccess.dll will not work as it requires several other unmanaged dlls to implement ODP.NET functionality.

Need Oracle Client tools 8.1.6 NT/2000

Hello, All I can find online are the 8.1.7 client tools, were can I obtain the 8.1.6 tools for nt/2000? We have the 8.1.7 tools,but are unable to export from a 8.1.6 server sucessfully and have instructed to obtain the 8.1.6 tools.
Thanks,

Yes.
Although we haven't shipped any library specific to 816, you can use the library that is
in
$WL_HOME/bin/oci815_8 directory.

Need Oracle Client 8.1.7.4 Version

I can find the 8.1.7.0 download but do not see an 8.1.7.4 version for download. How do I find that version and complete a download?

Patchsets are available from Metalink if you have a support contract. Unfortunately, you cannot generally get access to patchsets without a support contract.

Deployment of oracle client application

Hello,
I want to know if i can get connected to the Oracle Database Server 10g from my client system without installing any Oracle Client Software.
i have developed an oracle application using oracle client 10g in C#. i have to deploy this project in the client pc. it asks for a oracle client software.
is it must and should that the oracle client software be installed in the client pc. or any other measures to deploy the application without installing oracle client in the client pc.
thanks
ajith.

I want to know if i can get connected to the Oracle Database Server 10g from my client system without installing any Oracle Client Software.Yes you can connect without installing the client software in oracle 10g, the new tool is rather a folder and some settings called instantclient. See the link [http://www.databasejournal.com/features/oracle/article.php/3371561/Instant-Client-in-Oracle-10g.htm].
i have developed an oracle application using oracle client 10g in C#. i have to deploy this project in the client pc. it asks for a oracle client software.
is it must and should that the oracle client software be installed in the client pc. or any other measures to deploy the application without installing oracle client in the client pc.Depending of the binaries or jar files which you may be using in C#. If it is present in instant client then of course you can connect otherwise you have to install it. Connectivity with oracle database needs some net configuration, when you install oracle client the sql net is being installed. When you install java a java net is installed and using JDBC driver you can connect to the database. That is basic idea behind oracle connectivity.

Oracle client not needed--xcopy helps??

Suppose i am using Oracle 11g..and now releasing the website or win application.
Someone told me that we dont need Oracle client installed on machine (server where we are putting release)
(server where we are releasing we dont need client)
And xcopy or carring the dll in bin in release and thats it...
is that possible?? i have always installed client on application server...
if yes!! how and what are the steps. I am using asp.net framework 4

Oracle Client 11G R2

Application Name: Oracle Client
Application Version: 11G R2
Company Name: Oracle
Sequencer Version: 4.6
App-V Client Version Tested On: 4.6
Operating System Sequenced On: Server 2003 R2 SP2
Pre-requisites: None
Client Operating Systems Successfully Deployed To: Server 2003 R2 SP2 (x86), Server 2008 (x86), Server 2008 R2.
Posted by non-Microsoft Employee: Kevin Kaminski, Big Hat Group Inc.
Steps to Sequence the Application:
Before sequencing you may want a dummy user and system ODBC DNS in place so that the sequence can see other DSNs at the machine level.
Launch setup.exe.
Make sure InstantClient is selected and click Next.
Change the installation folder to Q:\Oracle11.001.
Ignore PATH error.
Select Finish.
Click Close.
Most environments provide a TNSNAMES.ORA and SQLNET.ORA files that are customized for the customers environment. It is a good idea to keep these files outside of the sequence to make them easier to update especially if you are going to use multiple sequences with the Oracle client. Make a folder off of the root of C:\ and put the files in there and set the environment variable based on the example below.
TNS_ADMIN=c:\OracleTNS
Create necessary ODBC DSNs.
Known Issues/Limitations: Oracle is working on a client to be supported on Windows 7 and Server 2008 R2. A release is expected in July 2010.
Approximate Sequencing Time: 30 minutes
Other (Optional fields)
App-V friendly copy protection scheme? N/A
Additional Notes/Links: N/A
Custom scripts to assist in the process: Can use pre launch script to update TNSNAMES.ORA and SQLNET.ORA if it is inside of the sequence.

Oracle Client Libraries

Where can I get the client libraries I need for Oracle 8.1.7 for a RedHat 7.2 Apache/PHP 4.2.2 Installation

Stuart Amos wrote:
Is it possible to use the JDBC 2.0 drivers for BEA Weblogic server without installing any of the Oracle client libraries. In the documentation. In the installation guide for Oracle jDriver in states that a full client installation of Oracle is required. Is this referring to the 384 Meg download that Oracle provide ??. If it is does this mean that Oracle client licenses are required for the web server ??Our Oracle driver is based on the Oracle client libraries, and the Oracle infrastructure, such as the tnsnames.ora
file, and the Oracle error message files in the Oracle client installation. I do not know how/whether Oracle licenses
it's client libraries. However, the Oracle thin (all Java) driver is useable anywhere, with nothing extra to install. It is
also more reliable than any driver based on Oracle's native client libraries. I recommend you use it.

Oracle Client Side connectivity issues from a Windows XP Machine

I am sure most of you guys may have addressed this issue of the time delay the client application takes to retrieve the data from the Oracle database. However, here's my problem.
We have installed a VB application running on Windows Xp along with an Oracle 8i client. Now when the application tries to connect to the database at times the data fetching speed is quick and at times its really slow... takes almost 15-20 minutes.. We're not sure if this is an application issue/oracle client configuration issue or a network issue..
We've wasted alot of time blaming the network/connectivity.. However, is there anything that we would need to check at the clients pc.. oracle config etc.etc.. ???
Please help..

Might want to try out a couple of things:
When it's running slow:
1. ping the server to see the response time of the server.
2. check the CPU usage on the server. There could be a resource crunch taking place due to other large and/or multiple transactions going on.
3. kill the VB connection and run the SQL from the command prompt and see how long it takes. Sometimes executing an SQL from the application may take longer, while from the command prompt, it's quicker. In this case, application tuning is required.
4. check to see the CPU and memory usage on the client PC itself. If there are multiple applications in use chewing up these resources, it can and will slow things down on the client PC itself.
Oracle client does not require configuration as such.

ASP to Oracle...without the Oracle client...

Hi there. I work in a university setting, complete with politics and territorial departments. I am authoring some web pages using third party software for the content management (which uses SQL Server); the 3rd party software requires these pages use ASP. However, there is some data I need to pull off of an Oracle Database and integrate with the regular content.
I have just begun to learn about my options for connecting to Oracle from ASP, and they all involve, if I understand correctly, installing the Oracle client software on the web server.
The department that controls the web server (Win 2000 IIS) has balked on installing the client software. They want to keep the machine "clean".
Is there a method for connecting to Oracle from ASP that does not involve installing the Oracle client on the web server? Maybe just a driver? Someone told me that I might be able to have the ASP page call a procedure on SQL server (which is not on the web server) which in turn connects to Oracle, pulls the data, then returns it to the ASP page. Sounds convoluted, but I guess if it works...
The issue is not going away; we are pretty much tied to ASP for our web development and Oracle for our database needs. Can anyone give me some advice on what direction I should take? Do I have any options? (Besides stealing the web server away...)
Thanks in advance...

If I were in your position, I would simply explain that if you want to pull data from an Oracle database and use that data to create dynamic ASP web pages, you'll need the Oracle client on the web server. 99%+ of the world does it this way, it'll almost certainly cost more to develop and maintain a nonstandard setup than it will cost to "depurify" the web server with the Oracle client. Save lots of headaches down the road.
Barring that, however, there are a few options technically available to you. I'll list them in my personal order of preference
1) There are some third parties (DataDirect is one) that sell "thin" ODBC drivers which don't require the Oracle client to be installed. They speak the Oracle wire protocol. You can use this thin driver and the Microsoft OLE DB to ODBC translation layer to communicate with Oracle. These aren't particularly cheap products as I understand it, but you may be able to negotiate terms. You'll still have to install something on the web server, it'll just be a smaller something than the Oracle client.
2) You could set up a SQL Server database on a separate machine (you could have SQL Server & Oracle on the same machine I suppose), install the Oracle client on that machine, and set SQL Server up to query from the Oracle database. Your ASP pages could query the SQL Server database on this machine, which would query Oracle and return the data. Not particlarly elegant, but doable. If you have to license the SQL Server install (i.e. you don't have a site license), this is probably more expensive & less elegant than #1.
Side note: the reason you don't need to install "SQL Server client" software on the web server is that Microsoft has helpfully decided that SQL Server client components need to be a standard part of Windows.
3) (Warning, speculative) The goal here is to use Oracle's thin JDBC driver (no Oracle client required) on the web server to query the Oracle database. I don't know if you could cobble together some database access components using Visual J++ called from ASP that called Oracle's thin JDBC driver. This strikes me as requiring a whole mess of bailing wire, duct tape, and chewing gum to hold together if it's possible, but has the benefit of not costing you money (just sanity, time, future maintenance...)
So, it's technically possible to do what you wnat.
I'd strongly advocate getting folks to understand the necessity of installing the Oracle client on their precious web server, no matter how pristine they think it is. If you're really backed into a corner, explain that you can go for option #1, but there will be a financial cost to doing so. Without knowing your precise requirements, I would tend to suspect that you won't be able to meet you project objectives with #2 & #3 both because they'll make development, design, and maintenance more difficult and because they'll involve more "moving parts" which will tend to make performance & reliability suffer. If this is a low-priority system that people won't rely on too heavily, you may be able to get away with it. Of course, if it's a low priority system, my guess is that you wouldn't have to time to develop it.
