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.

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 ---------------

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).

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 question

Does anyone know if there is a JDBC thin driver available for Oracle that supports "HTTP tunneling" of the SQLNET wire protocol?
Such a driver would package the SQL*NET data stream into HTTP or HTTPS packets and connects to a Servlet proxy on the Web host that unpacks the data and forwards the SQL*NET stream to the Oracle RDBMS and returns the response the same way.
This would help me overcome some firewall issues I'm seeing since HTTP/HTTPS ports are usually opened through a firewall. I know Sybase has a JDBC dirver that does this for their TNS protocol and was hoping some company has developed this for Oracle.
Thanks in advance...

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.

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.

Good Luck,

JDBC Thin Driver 8.17 Release 2

Is the Oracle Direct Driver (JDBC Thin Driver 8.17 Release 2) compatible with other oracle versions like 8.15 and 8.16? Is it backward compatible to older releases. I have tried it and it does work, but I want to make sure there are no known problems going backwards because we have several versions in our shop.
Thanks

Oracle JDBC Thin Driver and Firewall Problem

Hi!
We have Oracle 8.1.5 and Websphere App Server. There is a
firewall between the two. A servlet creates a connection pool
(not that of Wesphere's). The frontend is JSP/HTML (no applets).
The servlet uses the Oracle JDBC Thin Driver for DB Connections.
The problem is - Once the connection is freed, the connection
pool is not being able to retrieve it and hence it created
another one, thus reaching the max. # of connections and the
system hangs. Restarting the DB service flushes the connection
and the application starts running again...
There was a similar problem discussed in this forums long ago. I
have not yet tried mentioning the firwall port and IP in the
connection string. But apart from that, is there any other
setting I need to do (on firewall or for the connectionstring)
to deal with this problem?
Someone had suggested to punch a hole in the firewall for the DB
port - but we can not really do that in the current scenario...
I would appreciate if anyone could share their experience
regarding how they resolved this issue.
Thanks in advance,
Vijaya.

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.

Jdbc thin driver to connect oracle as internal

I need to connect to Oracle as Internal using jdbc driver, is there a way we can do this using jdbc thin driver. Actually I don't want to pass username and password as it will be harcoded in a properties file.
Please let me know.

Hi Minol,
Have a look at this code example that shows how to Connect to Database as internal ( as sysdba ). In this code sample the properties are hard-coded, you can supply these Properties by loading them from a properties file.

JDBC Thin-Driver and Oracle Stored Procedure

I've got a Oracle stored procedure which returns a Oracle record.
How can I retrieve the record in java using the JDBC Thin-Driver ?
Record:
TYPE messagerec IS RECORD
(log_level VARCHAR(2), timestamp VARCHAR2(19), text VARCHAR2(200));

Using PL/SQL BOOLEAN, RECORD Types, and TABLE Types:
Oracle SQLJ and JDBC do not support calling arguments or return values of the
PL/SQL BOOLEAN type or RECORD types. Also, when using the Thin driver, they
do not support calling arguments or return values of PL/SQL TABLE types (known
as indexed-by tables). TABLE types are supported for the OCI driver.
Check the following guide,
http://otn.oracle.com/tech/java/sqlj_jdbc/pdf/a96655.pdf

JDBC thin driver and Oracle 8.1.6

Hi,
I have installed Oracle 8.1.6 on Windows NT 4.0 with service pack 4 and using Oracle JDBC thin driver driver (classes111.zip). My application is multithreaded, but each thread maintains its own connection (and own set of Statements). Things are okay in single threaded mode, but in multi threaded mode, I get weird errors!
1. My resultsets are SCROLL_SENTITIVE and UPDATABLE
2. Sometimes, while updating a row, "No current row" SQLException is thrown, although a row exists that satisfies my select criteria
3. I am also calling executeUpdate() for inserting new rows and such rows are not seen by successive resultsets!
Appreciate any hints! Thanks!

Try this isntead.

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!
