JDBC in Linux

Since JDBC is a bridge to connect Java and Oracle via ODBC.
However, in Linux, there is not ODBC. Can I still use JDBC in
linux to access Oracle?

JDBC is NOT a bridge between JDBC and ODBC! Early versions of
JDBC might have used this to get a version out there for people
to use to code.
Oracle JDBC connects either thin (100% java) or OCI (via the
Oracle Client)

ODBC or JDBC on Linux/Oracle

http://www.openlinksw.com/
Is where you will find connectivity for LINUX and Oracle.
I did some research on the connectivity of LINUX and Oracle
after having switched from a Server Farm hosting IIS and then
going to linux.
The basic info I found was in about 20 links.
Some areas of interest might be:
http://www.linuxworld.com/ this is by INFOWORLD MAG but has the
best source and links for commercial Linux.
In addition:
http://users.ids.net/~bjepson/freeODBC/
The free ODBC might be a place to gain the functionality to get
the job done if you have the ability to code at that layer.
The reason WHY odbc is not the preferd method of accessing
Oracle is that OLE DB is thunked through the JET DATABASE ENGINE
or subsystem in WIN9.x and WINNT at the client side.
http://support.microsoft.com/support/kb/articles/q139/7/25.asp
This article goes into some detail how OLE DB, ODBC, ADO, RDO,
and the rest of the MSFT data is handled and by what files.
ORACLE uses "OLE OBJECTS" to get the data and passes the JET
DBENGINE/Sub-system.
So for a Server on Linux and a host on Wintel you might look at
the JDBC or universal Model of data connectivity.
Oddly this was just something I looked into prior to deciding to
get into Oracle8i....
If you get any additional info.. or other "workable" approaches..
Please follow up I would be interested...

Need help with Kerb. jdbc from Linux to MS SQL 2008

Hello Forum, I am getting an erro when I try to use Kerb. trusted security to connect to sql server.
4.0 documentation reflects it's absolutely possible.
Not only that, I have ms odbc installed on the same box and it provides Kerbers (not ntlm) connection to sql server. But java with jdbc reject doing it.

Saeed,
Not being versed in JAVA, I'm not sure what you're telling me. Can you tell me if this looks good? BTW, I did find out that JDBC is installed on the server as part of Coldfusion and this is what I was told:
macromedia.jdbc.oracle.OracleDriver is 3.50
macromedia.jdbc.db2.DB2Driver is 3.50
macromedia.jdbc.informix.InformixDriver is 3.50
macromedia.jdbc.sequelink.SequeLinkDriver is 5.4
macromedia.jdbc.sqlserver.SQLServerDriver is 3.50
macromedia.jdbc.sybase.SybaseDriver is 3.50
Below is what I think will work, but I know it won't because of the semi colons. Can you help me fix it?
I've the things that I think need changing are in bold.

Random SQLExceptions in JDBC on Linux

I have a test program that connects to a remote database from my Linux system(Red Hat 6.2) using the 8.1.6 JDBC thin driver. It loops 100 times, calling a function which does a simple select from a table. Approximately 20% of the time, I get an SQL Exception, either an ora-00942(table or view does not exist), ora-00933(invalid table name), ora-00933(SQL command not properly ended), or ora-00911(invalid character).
If I run this same program from Windows2000 or from a Solaris system, it never gets an SQL Exception. So, it appears to be Linux related. Have compiled and run the program with Java 1.2 and 1.3. Any ideas or suggestions? Following is the test program:
import java.sql.*;
import java.text.*;
import java.util.*;
import java.io.*;
* testQuery will attempt to reproduce a problem
class testQuery {
private static String sessionName = "[email protected]";
private static int exceptionCount = 0;
private static Connection dbconn = null;
static public void main (String args[]) {
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
} catch (ClassNotFoundException cnf) {
System.out.println("main: oracle driver class not found");
return;
try {
dbconn = DriverManager.getConnection("jdbc:oracle:thin:@myhost:1521:mydb","user", "passwd");
} catch (SQLException e) {
System.out.println("main: SQL Exception getting connection: " + e.getMessage());
if (dbconn == null) {
System.out.println("main: null connection");
return;
for (int i=0; i<100; i++) {
doQuery(sessionName, i);
System.out.println("Main program complete: there were " + new Integer(exceptionCount) + " SQL exceptions");
static public boolean doQuery(String name, int i) {
PreparedStatement pstmt = null;
try {
pstmt = dbconn.prepareStatement("select session_id from sessions where name = ?");
pstmt.setString(1,name);
pstmt.executeQuery();
System.out.println("Query <" + new Integer(i) + "> SUCCESSFUL!");

} finally {
try {

in that list of products i would have to say your open office will be your limiting factor, how fast do you want to do your spreadsheets or wordprocessing?

JDBC DRIVER LINUX TOMCAT APACHE

Hello all
I am woking on APACHE + TOMCAT + RH LINUX
enviorment . I have a main page which calls another JSP on clicking to a button . That JSP makes connection with oracle 7.3.4 which is running on another machine whose enviorment is AIX 4.2 .
whenever I clicked on button it access the JSP but it could nt find the driver which is classes12.zip in
TOMCAT_HOME/lib directory and classpath is already set
Error I am getting is driver not found in case the statement is
DriverManager.registerDriver (new oracle.jdbc.driver.OracleDriver());
and error is Document contain no data in case I change the above statement to
Class.forName("oracle.jdbc.driver.OracleDriver");
Please help ?
Thanks in Advance
Avi

Thanks for yor reply beattris
Still it didbnt work Please have a look at the code
<%
System.out.println("1");
Class.forName("oracle.jdbc.driver.OracleDriver");
System.out.println("2");
conn = java.sql.DriverManager.getConnection("jdbc:oracle:thin:@blackadder:1521:ORCL","driver","norman");
stmt = conn.createStatement();
rs = stmt.executeQuery("SELECT FILE_STATUS FROM GOLFFILES WHERE GOLFFILE_ID = (SELECT MAX(GOLFFILE_ID) FROM GOLFFILES)");
while (rs.next()) {
varIsUpdated = rs.getString(1);
rs.close();
stmt.close();
if (varIsUpdated.equals("START") && !(varIsUpdated.equals("LOADED"))) {
conn.close();
%>
Above is the code it comes to JSP and it prints 1 which is above the class.forName statement but after that it wont print 2 .. which means it is able execute this statement

How to do connectivity to JDBC on Linux platform

Hello friends!
I am novice user of JSP & JDBC. I dont know how to make connectivity with database using JDBC driver and that is using Linux paltform. I read one tutorial for that they have given some code. But they have used <% import java.sql%> . The database I am using is PostgreSQL. So how to do that?
Plese help me ! Thank you in advance!

Same as JDBC on any other platform. Java and JDBC are OS independent.
The java.sql package is part of the JDK, of course. No action required.
If you're using PostgreSQL, you have to get their JDBC driver JAR and put it in your app's CLASSPATH.
Then you should review this.

Urgent query JDBC on linux

I have an urgent query . I have written a java code on microsoft platform that talks with SQL server 2000 hosted on windows200 machine in a network using JDBCODBC driver wothou using a Data source name.
But this same code when i try to run on mandrake linux throws an exception as
java.sql.SQLException: [unixODBC] [Driver Manager] Data source name not found,
and no default driver specified.

MS provides a JDBC driver for MSSQL 2000, go to there site and download it.

Servlet and JDBC on linux

Hi,
I am running a servlet program on linux that retrieves some information from oracle database using jdbc.
I can run a normal java application also on linux with a database connection:
Class.forName("oracle.jdbc.OracleDriver");
Connection con = DriverManager.getConnection("jdbc:oracle:oci:@dbname", "username", "pswd");
For the same code above I have not been able to retrieve data from the same oracle database name.
I do not understand why I can use jdbc in a normal java program, but not in a servlet program.
Could someone please explain the problem to me?
Thanks

The alternative is to use the Sun rmic, which you'll find (probably) lives somewhere near javac, javap, javah et cetera.
You are not using the sun rmic, as the stacktrace shows.
Dont just tell us that your 'paths are all correct' - post the invocation of the compiler that causes the stacktrace, along with some environment, then you might get some more detailed help

Oracle9i jdbc on linux with Sun App Server7

Hello all,
I'm having trouble setting up oracle9i jdbc drivers on linux. I downloaded ojdbc14.jar from oracle's download site and put it in sun/domains/domain1/lib. I also added the jar file in the server classpath suffix, but somehow the connections are not going through. I wrote a simple java test application to test the drivers and that works perfectly. It's just the server that's not being able to connect for some reason. Any ideas? I use thin connection.

Yes, here it is (I use CMP beans):

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by JDBC Development Team:
The problem is that prior to 8.1.6 the OCI drivers are not supported using any VM other than Sun's. So, you have to do one of the following: upgrade to 8.1.6 client, switch to Sun's VM, or use the Thin driver.
The reason that IBM and MS's VMs are not supported is that they do not support NMI and prior to 8.1.6 the OCI driver uses NMI to maintain JDK 1.0.3 compatibility. We dropped support for JDK 1.0.3 in 8.1.6 and switched to JNI. The 8.1.6 drivers are supported on IBM's and MS's VMs.<HR></BLOCKQUOTE>

Sqlj and jdbc for linux

Hi All,
I am currently set up the (tomcat) jsp engine on top of apache web server.
And now i would like to install both sqlj and a jdbc driver such
that I can query our oracle database. In all of the options for downloads
there is a windoze option and a solaris option. Do I have to wait for specific
"linux" version to get them to work. Or is the solaris option alright
for linux ??
slightly confused,
Chris

Unfortunately, this description is still rather unspecific.
It sounds, as if there might be an issue with the way database connections are established for the SQLJ and JDBC parts of your program. Could you provide more information on that, specifically on how you obtain JDBC connections and SQLJ connection contexts.

Installing ODBC/JDBC on Linux

Anyone know of a quick method to install the necessary drivers for DBI on Linux.
I wish to connect to an NT Oracle DB from my Linux box using perl...

Hi,
1. The installation for OBIA 7964 is same as OBIE 7963 except the version difference of the tools like OBIEE. Follow the standard installation document. it will be better.
2.No need to upgrade Webcatalog. you have to copy the catalog from 7963 server and paste in the location, deploy and restart all services then it will start working
3. For RPD, copy the RPD from OBIA 7963 server. open the Admin tool in OBIA 7964 server and open the RPD(OBIA 7963 RPD) in the Admin too 7964 server and save it in the desired location(Desktop). Then the latest RPD is ready , you can deploy the RPD and start working with the 7964.
