Spy for oracle thin jdbc driver

Does anyone know a good spy utility to intercept the
query going to the database thru oracle thin jdbc driver?

If you can post the code, I would be happy to look at. I'm not aware of any 'trapping' mechanism for JDBC, although there may be one. Are you confident that you are 'waiting' on the execute of the SQL? It's very unusual for nothing to happen. In most cases, I would expect a long running query, or that you are getting, but not catching an Exception. Code would help if that's possible...

Oracle thin JDBC driver BUG-2285052, how to solve it ?

Hi, use ResultSet.getString to get a nchar type String from databaase, it will return the proper value.
eg, a 254 size column , it will return more char as needed !!
please check next from jdbc readme file. anyone can give me a temp solution ?
BUG-2285052 (since 9.2.0.1)
Extra space and null characters are returned by ResultSet.getString() and Scrollable ResultSet getString() for NCHAR column when the database national character set is UTF8. This behavior occurs only with JDBC THIN driver.

Dear Michael,
thx I found a lot of useful properties via the links you provided, but not those in question.

I think this refers to "Statement.setQueryTimeout".
The properties I'm looking for focus on the connection and the network beneath.
Are there other undocumented ;) possibilities?

URGENT!Can I user a THIN jdbc driver to access a CLOB field from oracle 8.0.5 DB?

URGENT!Can I user a THIN jdbc driver to access a CLOB field from oracle 8.0.5 DB?

I think you'd need to contact Oracle support to get access to older versions of the driver.
Since 8.0.5 isn't supported any longer, however, is it possible for you to update your Oracle client to one of the supported releases-- 8.1.7 or 9i?

Can weblogic server 5.1 version work with Oracle 9.2.0 thin JDBC driver?

we have an applicaiton using weblogic 5.1 and Oracle database 8.1.6. Is that possible
to upgrade databse version to Oracle 9i without weblogic upgrade? If yes, what
JDBC driver should be used? Oracle 9.2.0 thin JDBC driver or weblogic jDriver?
Is there any known issue with the JDBC driver under that architecture?
Please help.

Please help.Hi. Any weblogic server can be used with any JDBC driver. Just upgrade the
JDBC driver to the latest/best one for Oracle9i, and make sure it's the first
thing in the server's weblogic.classpath (not the java.classpath). I recommend the
thin driver. Because it's all java, it is much more reliable. There is no known
issue with standard JDBC with that or any other driver. Some non-standard Oracle
calls which arer available from Oracle's driver classes are available through
weblogic, and some are not.

Thin JDBC Driver is missing some rows from resultset

Hi All
I am faced with a peculiar problem.
When I fire a SQL query using Toad, I get correct results but firing the same query using JDBC Driver - ojdbc14.jar (ORacle 11g R1) - we are getting lesser number of records.
Our SQL pulls around 300k of records and buckets them based on some column value into different chunks. We use NTILE function and it shows right results in TOAD.
Using same sql with JDBC, We are losing 100 rows per bucket.
Any ideas?
SQL is
SELECT
T.CTLG_ITM_ID as catalogItemIds,
T.INV_STAT_TYP_ID,
T.OORD_DT,
T.LST_UPDT_DTTM,
T.CTLG_ITM_SELL_TYP_ID,
P.OORD_IND,
C.BKORD_ELIG,
NTILE(300) over (ORDER BY T.CTLG_ITM_ID) AS bucketId
FROM
INV_STAT_ROLLUP_T T,
PRD_T P,
CTLG_T C,
CTLG_TREE_PATH_T TP
WHERE
T.CTLG_ITM_ID = TP.CTLG_ITM_ID AND
TP.PAR_CTLG_ITM_ID = P.CTLG_ITM_ID AND
C.BRD_CD = '10'
As per toad, each bucket should get us 1038 records but Thin JDBC Driver is fetching us only 898 records.
Any idea why this discrepancy?
Thanks

http://www.oracle.com/technetwork/database/enterprise-edition/jdbc-111060-084321.html
There IS no ojdbc14.jar for Oracle 11g. The minimum is Java 5. So correct me if I'm wrong, but you seem to be using a very old driver here. I would try a newer one if I were you.

Connection string for Oracle in instantclient11_1 Driver without TNS

We have Oracle DB without tnsnames.ora.
We are able to connect to the DB using sqlplus from a command line with the following connection string:
username/Password@DomainAdress:Port/DataBaseName.DomainAdress
SYS/****@computerName.Domain.net:1523/DataBaseName.computerName.Domain.net
If we try to connect from the command line only with the DB name and not the FQDN – the connection fails.
We would like to connect using Driver={Oracle in instantclient11_1} We tried the following connection string:
Driver={Oracle in instantclient11_1};Dbq= computerName.Domain.net:1523/ DataBaseName.computerName.Domain.net;Uid=SYS;Pwd=**** as sysdba
We got the following Error:
[Oracle][ODBC][Ora]ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
What should be the right connection string for Oracle in instantclient11_1 Driver?

Thanks for the confirmation.

Problem with Java 5 and Oracle 10g JDBC driver

Hi All,
Currently we upgrade our web application to Java 5 and Oracle 10.2 JDBC driver. And we encountered a bug, when the user entered the information through UI and data didn't store into database (Oracle 9i). The problem is that this bug is not happend so often maybe once a day and this did not happen before we upgraded to Java 5 and Oracle 10.2 JDBC driver. Does anyone encounter the same problem ? Is this Java 5 problem or Oracle JDBC driver problem ?
Thanks,

sounds like a database problem...
Are you using a driver version that's supported for your database engine?
What else did you change? We once ran into a major bug in our application that had for 5 years been masked by performance problems in our hardware and infrastructure.
Once those were resolved the bug showed itself and caused tens of thousands of records to be erroneously inserted into our database every day.
It's certainly NOT a problem with your JVM (if it's a decent one, like the Sun implementation).
So it's either your database, your driver, your network (dropping packets???), or your application.
The upgrade may just have exposed something that was already there.

waiting for reply
sumesh

thanks for u'r reply.
you mean to say i need to install the new JDBC driver (Classes12.zip and nls_charset12) to the oracle/ora8i/jdbc/lib folder.currently this folder contains only classes102 and classes11.zip files and the corresponding charset only.After instaling the new classes12.zip file do i need to set the classpath?.

Oracle 7 JDBC driver

Hi,
I want to connect to an Oracle 7 database over JDBC. When I go to the download page, it only gives me Oracle 8 and higher download options, even though the documentation index lists an Oracle7 driver.
Does anyone know where I can get it from?

Thick vs. Thin JDBC Driver

Hi!
I was just wondering where to find some info about
the advantages / disadvantages of the Thick and Thin JDBC drivers, please, and some bachground about those drivers (what is the differnence etc).
In particular I would like to know whether Thick drivers are errorprone and mix up the contents of threads. Is this so according to your experience?
I would also like to know which one is the recommended driver to use if speed is an issue...
We use Oracle 8.1.7.4.0 and Websphere Application Server 4.04
Thanks a lot!
Cheers,
Steffen

Hi Steffen,

For Oracle : When will Oracle's JDBC Driver work for Date ?

I try to develop an application that will run on every database.
The only Database I have a problem with is Oracle because of date : I can't use executeQuery or executeUpdate with sql request that use a date field as a parameter.
And this stupid issue is only due to Oracles's non conformity to JDBC Standard.
I know that I can use preparedStatements and that it works, but It's not an issue : This is a minor bug that would be easy to correct so DO IT !
I also know that tit works with SQLJ, but I use Thin client.
I tried to change NLS_DATE_FORMAT, but with timestamp, time format got millisconds and Oracle don't like it ...
No, really, it's a long known bug.

I appreciate the confidence in SQLJ, but since SQLJ runs atop JDBC I would be very surprised if you did not encounter the same issue you are troubled with.
Unfortunately -not already knowing what your problem is- I do not quite understand what you are trying to point out here. Could you give us some code snippets and the expected versus actual behavior, so that we can understand and reproduce your problem? Or, if it is a known issue, would you have a bug assignment for it?
Thank you very much!

Problems with adding Library for a MySQL JDBC driver

Good day,
I am new with the JDeveloper package, so the following could be a user fault.
I found the following:
- I downloaded and installed Oracle JDeveloper 10.1.2.1.10 (latest version).
- I downloaded the latest JDBC drivers for MySQL. ( mysql-connector-java-3.1.10 )
Now, I did the following steps extracted from the link http://www.oracle.com/technology/products/jdev/tips/duff/mysql_and_oc4j3.html it should be quite easy to add the JDBC Drivers to the project.
I did the steps with the following results:
When I Edit the Project properties, follow Profiles -> Development -> Libraries
When I do ' New' , fill in at JS2E the value 'MySQL' and fill in the Class Path (in my case 'C:\javaInstalls\mysql-connector-java-3.1.10\mysql-connector-java-3.1.10-bin.jar').
In that case the [OK] is disabled. I should expect the [OK] button was enabled!
My question: Is this a bug? When not, what am I doing wrong!
Regards,
Mike

I tried it on an other system and had no problems with adding the libraries. It still is a problem on that particular system using the Dutch version of XP. The problem is that the Ok button stays disabled !
Could it bw a version problem with Java? How ever no changes are made to the original configuration, so it should pick up as default the java version of JDeveloper self.

How to set classpath for third party jdbc-driver

my application contains bc4j jsp. when i try to run this jsp application which connect to postgresql, i get a error message
"Application Error
Return
Error Message: JBO-30003: The application pool (App_ModLocal) failed to checkout an application module due to the following
exception:
Error Message: JBO-26061: Error while opening JDBC connection."
how to solve this.

The JDBC for your database should be added to your client project.
In JDeveloper created a new 'named' library item and specify the JDBC jar files for your database.

Can't find example source for Secure Thin JDBC Connection Sample

I've found information about an aspect of JDBC usage that I desperately need, but can't find the example source associated with it. The page is:
http://www.oracle.com/technology/sample_code/deploy/security/files/secure_thin_driver/readme.html
It would be useful to have the link to the example source JAR directly on the page.
Any assistance you could provide would be greatly appreciated.

Hi Peter,
the page you post has a link to jar file at http://www.oracle.com/technology/sample_code/deploy/security/files/secure_thin_driver/secure_thin_driver.jar
this jar has many example source codes. Just unzip it... or unjar it typing jar xvf SecureThinDriver.jar
