JDBC-Oracle-Driver

Hi all,
where can I download an JDBC-Oracle-Driver except of Oracle itsself?
Tnx
Marko

You could use the thin[i] driver.
Or, if you find a provider other than Oracle... you can... but, exactly, why do you want to do that???

application server. For standalone applications needing a type-4 driver, there is
Oracle's own, and commercial drivers like DataDirect's.

JDBC Oracle driver and Analytic sql support

I get the following error when trying to issue an update using a prepared statement in JDBC.
ORA-01006 : BIND Variable does not exist.
The statement in question is:
UPDATE TABLE_A SET A_COL = ? WHERE ID = (SELECT ID FROM (SELECT ID, ANO, REP_PERIOD, ROW_NUMBER() OVER ( PARTITION BY ANO ORDER BY REP_PERIOD DESC NULLS LAST) rn FROM TABLE_A WHERE rn = 1 AND ANO = '?')
If for instance, I substitute a hard value for "ANO = ?" - for e.g. ... ANO = 'ABC' the JDBC Update statement works fine.
Oracle ver. is 8.1.7, driver is the thin driver - both 8.1.7 and 9.0.2.0.1 tried.
Does Oracle's JDBC driver support analytic queries?
cheers
Aj

You don't want to have the quotes around the latter question mark. Right now, you're instructing the query to look for rows where ANO is the literal '?'. Remove the quotes and JDBC will recognize it as a bind variable.

Is there free jdbc type4 driver for oracle?

i neen to connect to oracle to develop my application, but there's a problem when tryin' to resolve peoblem of character set. in oracle, as i know, it uses unicode that resulting in the font code, which is not falling into the character set of unicode, whould cause failure in translating user defined font code. beside, for i do not know what kind of license that oracle jdbc type4 driver publishes, hope someone are able to tell me wheather there's any software like freetds in sql2000, because, if necessary, i may need to redistrubite the jdbc driver for my own use!
thanks in advice,

Oracle has drivers available from their site (free ones) for java and the specific version of Oracle you are running.

Oracle 9.2.0.6 client JDBC OCI driver compatibility issue with JRockit 1.4.

I have weblogic server 8.1 sp4 running on Linux E3.0 using JRockit 1.4.2_5.
I cannot seem to get the Oracle driver ojdbc14.jar to work. Yes I have added $ORACLE_HOME/bin to my classpath prior to any weblogic classes, I added $ORACLE_HOME/lib and $ORACLE_HOME/jdbc/lib to my LD_LIBRARY_PATH with no luck.
I get the error "no ojdbc10 in java.library.path".
I keep reading in the JDBC driver notes that the driver is compatible with different version of JDK 1.x but not JRockit. Perhaps Oracle 10 has this fixed.
Anyone experiences the same problem ? I am stuck ..

Oracle database 10.2 drivers ojdbc14.jar may also be used with JDK 5.0.

Bug in Oracle JDBC thin driver (parameter order)

[ I'd preferably send this to some Oracle support email but I
can't find any on both www.oracle.com and www.technet.com. ]
The following program illustrates bug I found in JDBC Oracle thin
driver.
* Synopsis:
The parameters of prepared statement (I tested SELECT's and
UPDATE's) are bound in the reverse order.
If one do:
PreparedStatement p = connection.prepareStatement(
"SELECT field FROM table WHERE first = ? and second = ?");
and then bind parameter 1 to "a" and parameter to "b":
p.setString(1, "a");
p.setString(2, "b");
then executing p yields the same results as executing
SELECT field FROM table WHERE first = "b" and second = "a"
although it should be equivalent to
SELECT field FROM table WHERE first = "a" and second = "b"
The bug is present only in "thin" Oracle JDBC driver. Changing
driver to "oci8" solves the problem.
* Version and platform info:
I detected the bug using Oracle 8.0.5 server for Linux.
According to $ORACLE_HOME/jdbc/README.doc that is
Oracle JDBC Drivers release 8.0.5.0.0 (Production Release)
* The program below:
The program below illustrates the bug by creating dummy two
column table, inserting the row into it and then selecting
the contents using prepared statement. Those operations
are performed on both good (oci8) and bad (thin) connections,
the results can be compared.
You may need to change SID, listener port and account data
in getConnecton calls.
Sample program output:
$ javac ShowBug.java; java ShowBug
Output for both connections should be the same
--------------- thin Driver ---------------
[ Non parametrized query: ]
aaa
[ The same - parametrized (should give one row): ]
[ The same - with buggy reversed order (should give no answers):
aaa
--------------- oci8 driver ---------------
[ Non parametrized query: ]
aaa
[ The same - parametrized (should give one row): ]
aaa
[ The same - with buggy reversed order (should give no answers):
--------------- The end ---------------

Using Oracle driver in JDBC for Unix and Linux based servers

Please, let me know how to mention the Oracle driver within the forName.class(" "); statement in the Jdbc-Servlet for Unix and Linux based servers.
I'm using Windows-OS for Java programming. Should I have to use the same environment(Unix/Linux with Oracle) for compiling or just compiling, mentioning the driver in the java program would suffice?
Please, Help me.
Thank You.

I've used Oracle's thin driver like this:
Class.forName ( "oracle.jdbc.driver.OracleDriver" );
Connection DBConnection = DriverManager.getConnection("jdbc:oracle:thin:USER/PASSWD@database" );
You need Oracles client classes ( e.g. classes111.zip ) at run time, not during compilation.
Thin client connects directly to the Oracle DB, so the database description is like PORT:MACHINE:SID
Connection is made through Oracle's listener even when your DB is in the same machine that your program is running. Port number is propably 1521 or 1526, depending on your listener.ora definitions and used Oracle SQL*Net version.

Connection reset using JDBC Oracle thin Driver (towards 10g DB)

Hi we have a home-grown application and a Oracle 10g (10.2.0.1) database.
We created a scheduled servlet that gets a JDBC connection from a persistent connected cache (an OracleDataSource object registered using OracleConnectionCacheManager). The servlet runs every 15 minutes and runs the query "SELECT SYSTIME FROM DUAL" on 10g Database as XYZ user. The datapool was created yday on web-app and all queries ran successfully for about 5 hours after which it reported a connection reset error.
I can then conclude that we cannot keep the server session alive for the JDBC client by running frequent SQL queries.
We didnt get any messages on the DB server side that indicate the release of the session
Ultimately, we are struggling with reset connections from our applications that are
using the JDBC thin oracle driver; after a couple of hours of idle
connections, we receive the below error from the JDBC driver:
Jul 5, 2007 10:59:53 AM oracle.jdbc.driver.DatabaseError throwSqlException
WARNING: DatabaseError.throwSqlException(e): Unable to find ORA number from
exception Jul 5, 2007 10:59:53 AM oracle.jdbc.driver.DatabaseError

WARNING: DatabaseError.findMessage(errNum, obj): returned Io exception:
Connection reset Jul 5, 2007 10:59:53 AM
oracle.jdbc.driver.PhysicalConnection getWarnings
INFO: PhysicalConnection.getWarnings()
Any suggestions please ?
Vk

The code itself is fine; the problem is with one of:
1) the connection URL
2) intermediate networking
3) the database itself
1) your connection URL is "jdbc:oracle:thin:@127.0.0.1:1521:orcl"
- is Oracle really running on the default port, 1521
- is the installation SID really "orcl"
2) lots of possibilities, but only a couple are likely
- is TCP/IP configured and running on your host
- is there a persoanl firewall rpduct running? perhaps it's blocking the connection
3) Is Oracle running?
Is the listener running?

Jdbc oracle jdbc-thin driver subname

I am working on Windows 2000 environment, using oracle8i 8.1.7 JDBC-Thin driver for use with JDK 1.2.x. The oralce8i 8.1.7 database is on another linux box. I can access the linux box through its ip address, but not by its hostname since it's not accessiable by the dns server. In my code, in the JDBCUrl, I used ip address instead of the hostname, e.g. "jdbc:oracle:thin:@10.0.113.108:1521:ora1". But I got the error like: "java.sql.SQLException: Io exception: The Network Adapter could not establish the connection". If I add a entry in my working machine's hosts file to map the hostname, I can fix the problem. But I don't know if this is the solution, or there is other better solutions.
Thanks

Using a hosts file entry is a common solution for problem where the dns lookup does not contain an entry for a RDBMS server platform.
The real solution is to resolve this issue :
"where the dns lookup does not contain an entry for a RDBMS server platform."

Oracle Jdbc Thin driver and nls suppot

Hello,
I have a hungarian database with nls_lang variable set to hungarian. I'm trying to do a jdbc connection using classes12.zip
but I'm getting the hungarian characters converted to question marks or other characters.
I read suggestions that I must include the nls_charset12.zip in my classpath too. So I did that but I'm still having the same problem.
What is missed??
How do I get the right hungarian charachters without any conversion.
This is becoming frustrating and I'm not able to solve it yet.
Thanks for your help

One more question -
Can we use Oracle JDBC OCI driver? We do not have any appletes...
Does it have firewall issues too? Is there any other driver that
we can use?
Thanks,
Vijaya.

Oracle JDBC Thin Driver

I am using CLOBS with the Oracle thin driver and am experiencing horrible performance. We need datavalues more than a VARCHAR2 and have used CLOB but the method Oracle uses to get the data in and out is super slow.
MS SQL Server JDBC with text is awesome and fast. But Oracle is slow and very cumbersome.
Help

We are using 9.0.2.
So what you are saying is although the column is CLOB
in Oracle 10 g we can use a normal result set
rset.getString( 1 ) no special oracle stuff just the
e Oracle thin driver for 10g?
Also this will retrieve a String greater than 4000
bytes?Exactly. Not only you can retieve a clob as string, you can also insert clob
as a string too. Here is the code I referred in last post in case you do not
have access to oracle ten network:
