Looking for Bug description 3133645 in JDBC-Thin-Driver

Looking for Description of Bug Number 3133645. An error "Sorry, this page was not found" occurs, when calling this page.

Well actually...
If the "prepareStatement()" invocation worked, but the "execute()" invocation failed (which matches the situation you have described in your original post), then the "PreparedStatement" would, most definitely, not be null, and the "close()" method (as per my sample code) would, most definitely, be executed.
So I still get the impression that you are probably not closing your "Statement" instances (in cases where an error is occurring).
Also, in my experience with Oracle's "thin" JDBC driver (i.e. the "classes12.zip" file), closing a "Connection" does not close any "Statement"s associated with it -- "Statement"s need to be explicitly closed.
Perhaps you need to check your code again -- or post your actual production code for a third-party to scrutinize.
Good Luck,
Avi.

Sql_trace does not work for Java app using Oracle JDBC thin driver

Hi,
I'm using Oracle 8.1.7. I enabled sql trace at instance level by setting sql_trace and timed_statistics to true in init.ora. I restarted the db instance. I wrote a stand-alone java application which used Oracle JDBC thin driver(classes12.zip) to make a connection to my db instance, do some select statements, and close the connection. There were no trace files generated in the folder specified by udump_dest variable. However, if I used sqlplus or dba studio, I saw trace files generated. Has anyone got Oracle sql trace work for JDBC calls from java apps.
Thanks in advance!

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):

Error Code Definition for JDBC Thin driver

Would like to know where I can find the definition of error codes
for JDBC thin driver to Oracle 7 database. Right now, when I have
database errors, I get SQL execption with CODE=XXXXXX. Need to
know the definition of the error codes in order to decide whether
the application shall retry or quit or do something else. Thank
you in advance.

Hi,
thin client session Language is controlled by java Locale.
Based on testing code, ORA- messages are localized after the connection is successfully established. ORA- messages returned in the middle of connecting are in instance language.
So, as far as I can say, you need to catch exceptions from DriverManager.getConnection(url, info); and translate them on your own.
Once the connection is successfully returned, ORA- message language is defined by java Locale.
Tests were performed on Oracle 10gR2 (both thin driver and DB).

Oracle JDBC Thin Driver for oracle 9.2.0.4

Hi,
It would be nice if someone please guide me to the download of Oracle JDBC Thin Driver for oracle 9.2.0.4.
Thanks in anticipation

user566773,
As far as I know, all Oracle JDBC drivers are meant to be backward compatible.
According to the table on the following Web page, the latest Oracle JDBC driver can be used with Oracle 9.2.0.x DBMS.

JDBC thin Driver 8.0.X Limit 2k for varchar2?

I am using Oracle JDBC thin driver 8.0.5.0.0 to query Oracle
8.0.5 via SQL net. The problem I met is every time I try to
retrieve data for varchar2 (over 2k), it get truncated and only
return the first 2k without throwing any warning or exception.
I tried getString(), getAsciiStream() and getBinaryStream(), and
the results are still the same. The SQL Net works fine, since it
successfully returns over 2k varchar2 type data when programing
with PERL.

JDBC Thin Driver Support for Data Encryption and Integrity

Hello JDev Team,
I am trying to implement JDBC Thin Driver Support for Data Encryption and Integrity.
It works fine with java.sql.Connection and java.util.Properties like in the following code:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Properties props = new Properties();
int level = AnoServices.REQUIRED;
props.put("oracle.net.encryption_client", Service.getLevelString(level));
props.put("oracle.net.encryption_types_client", "( RC4_40 )");
props.put("oracle.net.crypto_checksum_client",Service.getLevelString(level));
props.put("oracle.net.crypto_checksum_types_client", "( MD5 )");
Connection conn = DriverManager.getConnection ("jdbc:oracle:thin:@localhost:1521:main", props);
etc...
But I am developing an application with InfoSwing components and it has a different way to connect to Oracle database using oracle.dacf.dataset.connections.Connection, like this:
sessionInfo1.setAppModuleInfo(new ModuleInfo("bc", "BcModule"));
sessionInfo1.setConnectionInfo(new LocalConnection("JDBCThin"));
sessionInfo1.publishSession();
My question is:
Is there any way to implement DataEncryption and Integrity into this type of connection?
Thanks a lot in advance.

Victor,
No, you can't do this from DAC, but I've been discussing it with the developer, and we both think this capability would be useful to have, so I've logged it as an enhancement request.
I do have a question for you. Once you've made the JDBC connection, do you need access to the Connection object afterwards? We're thinking of how the change could be implemented, and one way would be to allow you to pass in a Properties object when creating your own NamedConnection.
Thanks

Is jdbc thin driver not designed for internet use?

Is jdbc thin driver not designed for internet use?
The size of the thin-driver file is about 1MB of size and is
too large if were to ask clients to download it from the
internet.
Can anyone advise on this issue?

You need to remote onto the server and go into start->control panel-Administration-> ODBC (or sometimes start->administration->ODBC) and set up ODBC connections . Make sure you set them up on the system tab, then you should see them in EAS. I don't remember, b ut don't think you need to restart the Essbase servise for them to take effect

Oracle 8 JDBC thin driver for tomcat

Hi all,
I have tomcat3.3 installed on HP UNIX with java version "HP-UX Java C.01.18.05"
I need to connect to an oracle 8 database using a Oracle JDBC thin driver. Where can I obtain this driver? How to install and configure it for the tomcat application?
Thanks for your help.
Regards

If you go to the link which the last person posted, http://technet.oracle.com/software/tech/java/sqlj_jdbc/content.html, there is no indication for HP-UX. The only OS it lists are NT and Solaris. Does anyone know if these versions will work on HP-UX?
Please help.

Try get the latest thin driver from oracle and place it in the beginning of
the classpath in the server startup script to use it. This seems like a
oracle thin driver bug, the newer driver might help.

The easiest thing to do is download it as an archive with your applet.
Otherwise, you have to have the files on every client machine.
For netscape, put the classes111.jar in the java classes folder typically:
c:\ProgramFiles\Netscape\Communicator\Program\java\classes.
I'd expect that IE would be setup in a similar way.

Problem using JDBC Thin driver with Oracle 8i Personal Edition

Hi all, I have an issue I have been unable to figure out. In order to make my code as portable as possible I am using the JDBC thin driver to access my database. I have been able to connect to an instance of Oracle 8i on a Sun box by hardcoding the following string into getConnection() call:
conn = DriverManager.getConnection("jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(COMMUNITY=tcp.world)(PROTOCOL=TCP)(Host=<myhostname>)(Port=1521))(ADDRESS=(COMMUNITY=tcp.w orld)(PROTOCOL=TCP)(Host = <myhostname>)(Port = 1526)))(CONNECT_DATA = (SID = <mysidname>)))", <myuser>, <mypassword>);
My problem is that I cannot figure out what string to use to connect to my local instance of Oracle 8i Personal. I used the following string (the sid I got from the looking at the init.ora file):
conn = DriverManager.getConnection("jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(COMMUNITY=tcp.world)(PROTOCOL=TCP)(Host=localhost)(Port=1521))(ADDRESS=(COMMUNITY=tcp.world)(PRO TOCOL=TCP)(Host = localhost)(Port = 1526)))(CONNECT_DATA = (SID = orcl)))", "scott", "tiger");
That didn't work, so I took the only entry found in my tnsnames.ora file in as:
conn = DriverManager.getConnection("jdbc:oracle:thin:@(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0)))(CONNECT_DATA = (SID = PLSExtProc)(PRESENTATION = RO)))", "scott", "tiger");
I am not knowing what is wrong, but that didn't work neither. Any suggestions would be highly appreciated.
Thanks....

try this:
conn = DriverManager.getConnection("jdbc:oracle:thin:scott/tiger:@hostname:1521:sid");
or use system/manager as username/passward

Using JDBC-thin driver

Hello,
I am using CMSDK on a propretary software, after the upgrade to version 9.0.3, it seems that the API uses by default the OCI driver and it looks for the db url from the domain url when starting the IFS service.
The problem with that is the JDBC-OCI driver character encoding of utf-8 charaters in C which transforms the characters in an unwanted form (I use arabic characters in input and get garbage stored in the database).
Is there a way to make CMSDK uses the jdbc-thin driver instead of jdbc-oci driver?
I hope so, and I would like to know how to do it.
Thanks in advance.

Hello everybody,
I could finally use the JDBC-THIN driver by directly changing the IFS.SERVICE.JDBC.DriverType property in the database repository to thin (by default it is oci8).
Since there are three different services configurations someone must change the correct one.

Jdbc thin driver bulk binding slow insertion performance problem

Hello All,
We have a third party application reporting slow insertion performance, while I traced the session and found out most of elapsed time for one insert execution is sql*net more data from client, it appears bulk binding is being used here because one execution has 200 rows inserted. I am wondering whether this has something to do with their jdbc thin driver(10.1.0.2 version) and our database version 9205. Do you have any similar experience on this, what other possible directions should I explore?
here is the trace report from 10046 event, I hide table name for privacy reason.
Besides, I tested bulk binding in PL/SQL to insert 200 rows in one execution, no problem at all. Network folks confirm that network should not be an issue as well, ping time from app server to db server is sub milisecond and they are in the same data center.

I have exactly the same problem, I tried to find out what is going on, changed several JDBC Drivers on AIX, but no hope, I also have ran the process on my laptop which produced a better and faster performance.
Therefore I made a special solution ( not practical) by creating flat files and defining the data as an external table, the oracle will read the data in those files as they were data inside a table, this gave me very fast insertion into the database, but still I am looking for an answer for your question here. Using Oracle on AIX machine is a normal business process followed by a lot of companies and there must be a solution for this.
