JDBC-OCI (8.1.6) - Weblogic

Hi,
I am trying to get weblogic 4.5 to connect to an Oracle 8i database.
The database and listener are operating fine, but so far I cannot connect from weblogic.
1) What type is the JDBC-OCI driver for 8.1.6 (supporting JDK 1.2)?
2) Do I need to install the OCI driver as well as the JDBC driver on the weblogic server? If so, where do I get the OCI driver?
Regards,
Ultan

Your questions are confusing. You seem to consider OCI Driver and JDBC Driver as 2 versions of drivers, but in reality the former is a type of the latter.
Oracle supplies 2 types of JDBC drivers, i.e., Type II, or the OCI driver, and Type IV, the Thin driver. They are both contained in the classes111 or classes12.zip file. To use the OCI driver, you need to install the Oracle Client Library (OCI library).
To use these drivers with WebLogic, you need to include the path to the classes111.zip file in your weblogic.class.path variable in the startWebLogic.bat or .sh script file, or set it in the Windows Registry.

XA transaction using weblogic.jdbc.oci.xa.XADataSource

Hi everyone, I am trying to execute XA transaction using the driver XA compatible
driver
weblogic.jdbc.oci.xa.XADataSource. I have added c:\bea7.0SP4
\weblogic700\server\bin\ntvinv\oci817_8\weblogicoci38.dll in the PATH in my
weblogic managed server startup script.
When I start managed server, I get the error saying that weblogicoci38.dll

it clearly shows that java.library.path contains this file. Please suggest
me what to do.
I have weblogic 7.0 with SP4 and databse is oracle 8i.

load a method from XYZ.DLL, and finds the DLL, but in order to load that method,
it finds it needs to also load ABC.DLL (such as the Oracle OCI DLL or the OS C libraries)

JDBC/OCI driver for JDK1.2

Hi,
I have an evaluation copy of Oracle8 version 8.0.3.0 and
downloaded the JDBC/OCI driver for JDK1.1 (classe111.zip). The
example I used was also taken from this site, which connects to
the database and lists ename from emp, using scott/tiger.
Everything worked fine under JDK1.1 but I can't get the code to
work with JDK 1.2
Does Oracle provide a JDBC/OCI driver that will work with JAVA
1.2 or am I missing something. Please note that I am not using
Oracle8i.
Any assistance would be greatly appreciated.

Karim,
Openlink Software (http://www.openlinksw.com) provides JDBC 2.0
drivers in version 3.2. This version will be hitting our public
web site next week, but you can get pre-release components from
ftp://ftp.openlinksw.com/pre-3.2/index.html
The JDK 1.2 drivers are all the way at the bottom under the
Windows section.

AIX JDBC OCI Driver

I'm using IBM's WebSphere JDBC connection pool to manage oracle
connections. While the code worked normally on Sun Solaris, I
get ORA-03123, ORA-03127 etc errors on AIX. I'm closing the
resultsets, the statement handles and releasing the connection
after each SQL execution. Is this an AIX JDBC OCI driver problem
or am I missing something.

Jdbc oci interface and xdb API for oracle 9.2.0.7

I have a Java application that uses the jdbc oci interface to connect to an Oracle database and insert some XML into an XMLType column using the XDB APIs provided in xdb.jar.
OS : IBM AIX version 5.1
JVM : IBM 32-bit SDK pour AIX, Java 2 Technology Edition, version 1.4.2
libraries used :
ojdbc14.jar
nls_charset12.jar
xdb.jar
xmlparserv2.jar
libocijdbc9.so
with Oracle 9.2.0.1 the application worked correctly. However we have just upgraded from Oracle 9.2.0.1 to Oracle 9.2.0.7 and now the JVM crashes when the XMLType.createXML(java.sql.Connection, java.lang.String) API is called. The error message is :

Does anyone have any ideas? Changing the version from 9.2.0.7 is not an option.
Thanks,

The 9.2.0.5 patchset, and all patchsets, are available for download from Metalink.
There should be a rather large variety of JDBC drivers that will connect to an 9.2.0.5 database if that's what you're asking about.

Please this is not simple as simple as checking the classpath and LD_LIBRARY_PATH.
I tried the sample program and the result is the same. As pointed out first by Won, putting the libocijdbc8.so from SDK8.1.6 in the LD_LIBRARY_PATH has no effect at all. It gives the unsatisfied linker error. The sample program fails. However the sample program works fine with the libocijdbc8.so from sdk8.1.5. The library gets loaded. But at the time of creating the connection it gives make_c_state error.
Here is my CLASSPATH, PATH and LD_LIBARY_PATH variables
ORACLE_HOME=/opt/oracle/product/8.1.5
LD_LIBRARY_PATH=/usr/local/lib:/usr/lib:/opt/oracle/product/8.1.5/lib
PATH=/usr/openwin/bin:/usr/sbin:/usr/local/bin:/usr/ccs/bin:/usr/ucb:/opt/oracle/product/8.1.5/lib
Hope you are able to provide better answer then check your environment variables.
THE libocijdbc8.so FROM SDK8.1.6 DOES NOT GET LOADED AT ALL.
Waiting for the reply.
Please Help.

Memory Leak in 8.1.6.0.1 JDBC/OCI for Solaris

Hello,
there is a memory leak in the 8.1.6.0.1 JDBC-OCI driver for solaris.
The leak causes your jvm to eat up all memory
if you reuse callable statements
(calling one statement multiple times with
different values).
The thin driver has no such problem. Is
there any fix available ?

Ok. The code spans multiple classes and
most of it comes from a customized version
of the Enhydra Java Application server.
I have a class called "StandardDBConnection"
which caches CallableStatements and is a
wrapperclass for java.sql.DBConnection. The
interesting method here is "prepareCall":
* Get a callable statement given an SQL string. If the statement is
* cached, return that statement, otherwise prepare and save in the
* cache.
* @param sql The SQL statement to be called.
* @return a new CallableStatement object containing the
* pre-compiled SQL statement.
* @exception java.sql.SQLException If a database access error occurs
* statement.
public synchronized CallableStatement prepareCall(String sql)
throws SQLException {
PreparedStatement preparedStmt;
logDebug ("Prepare call: " + sql);
validate();
preparedStmt = (PreparedStatement)preparedStmtCache.get(sql);
// Check if the object returned by the cache really is a
// callable statement. if it is not, someone did call first
// prepareStatement() and now prepareCall() with the same
// sql. Silently replace the existing cache entry by a
// callable statement in this case.
if (preparedStmt instanceof CallableStatement) {
preparedStmt.clearParameters();
else {
// Need to close the old PreparedStatement in case we have to
// replace it with a CallableStatement
if (preparedStmt != null) {
preparedStmt.close();
else if (preparedStmtCache.size() >= maxPreparedStmts) {
String key = (String)preparedStmtCache.keys().nextElement();
((PreparedStatement) preparedStmtCache.remove(key)).close();
preparedStmt = connection.prepareCall(sql);
preparedStmtCache.put(sql, preparedStmt);
return (CallableStatement)preparedStmt;
The statements get closed when I close the
connection:
boolean closeStmts = true;
// Close the prepared statements.
Enumeration e = preparedStmtCache.keys();
while (e.hasMoreElements() && closeStmts) {
String key = (String)e.nextElement();
try {
((PreparedStatement)
preparedStmtCache.remove(key)).close();
} catch (SQLException except) {
// Ignore errors, we maybe handling one.
closeStmts = false;
log.write(Logger.NOTICE,
"DBConnection[" + id + "]: " + url +
"\nUnable to close statements. Continuing....\n");
In my classes using database queries I just
use the prepareCall method of DBConnection
and do not have to care about anything.
Works perfectly with the thin driver, but
as soon as I switch to oci... :-|

How do you install the JDBC-OCI patch for a Windows NT4 IFS Installation?

I am about to install IFS on a Windows NT4 Server. I dont understand the instructions for installing the JDBC-OCI patch.
How do you install the JDBC-OCI drivers?
Do I install them after installing Oracle 8.1.6? and before installing IFS?
Is it necessary to install them?
I would be grateful for as much help as possible, I have never done anything like this before.

How to involve time in a date column in JDBC OCI 8.0.5.2.

Hi,
I need to involve time in a date column in JDBC OCI 8.0.5.2.
The default date format is like "09-Sep-1999". I could use it
but just need time involved too, like "09-Sep-1999 10:11:12".
I tried to use JDBC's Timestamp whose format is like
1999-9-9 12:00:00.000, just same as the dates selected from my
table,
but got an error message "literal doesn't match format string".
The JDBC document said Oracle's date could be JDBC date,
timestamp and char.
Thanks a lot!

Try placing the jar file in the

Oracle JDBC OCI doesn't work on Linux

Hi,
I'm using Oracle on Linux(RH6, kernel 2.2.13)
Oracle works fine.
JDBC Thin driver -OK!
But java receives SIGSEV when I'm using JDBC OCI. More specific, it seems to be a problem with the so library associated to this driver, cause this SIGSEV happens in a native method.
Help?

Have you posted this question to the JDBC/SQLJ Users group on Technet.
This is a JSP users group.

Execution of first request takes lot of time with JDBC OCI

Hi,
We are having an application which connects to Oracle server(10g Enterprise Edition Release 10.2.0.4.0 64bit) using Oracle JDBC OCI driver(10.2.0.1.0 production (10g R2)).
Everything works fine.
But what we observed is randomly the first request to the server vai JDBC driver in a day takes lot of time, varies from 5-15 minutes.
If we execute the request again it executed immediately
What we observed while debugging is preparedStatement.executeQuery() is taking time.
We enabled logging at the JDBC driver layer and a snapshot isgiven below. Between T2CPreparedStatement.doDefineExecuteFetch () and T2CPreparedStatement.execute_for_rows () it takes 5 minutes. Any idea why it takes this much time and reason for it? Oracle driver is not throwing any exceptions

Hi,
Thanks for the reply
- SQL may vary. Its not the same query which takes time always. The same query executed immediately(using another connection from pool) works perfectly
- If there is a failover or stale connection getting closed or timeout, will JDBC driver thhrows exdeption? I didn't see any exceptions in the driver logs. Is there anyway to identify whether failover or timeout is happening?
Some other points
- The application uses connection pooling. This means that connections are created in the beginning and kept in the pool. And it may be in the pool for 72 hours or , before this issue happens
- Application uses prepared statements and the statements are preapred and kept and re used later. So the query which take s more time might be prepared before 48 hours or so.
- This is not happening every day. Many times the pattern is , it happens after 60-72 hours after application is started.

Error Message: No ocijdbc8 in java.library.path
Dose any one knows about this? If so, Please let me know.
Thanks
