OCI8 JDBC driver causes memory violation
I'm trying to use the oci8 JDBC driver (under NT) and I'm sure it
used to work but when I try it now I just get a windows memory
error showing up in a dialog (the memory could not be "read"
thing). Any ideas what's cuasing this?

Looks like this is a thread safety issue. Other parts of the application were not synchronizing on the connection; adding the synchronization fixed the problem.

Type 2 jdbc driver cause weblogic thread dump
we have weblogic 5.1(sp6) running on redhat linux 7.1
we install oracle client (8.1.7.0.0) and jdbc12(classes12.zip).
the connection pool use type 2 driver
oracle.jdbc.driver.OracleDriver
the jdk is 1.3.1 b24 (we have try -native -server -hotspot)
sometime weblogic crash , the error output is:

for some reason , we can't change to type 4 driver .
any advice is very thanksHi Owen,
You may have to get the latest patchset from oracle for your OCI client
libraries. You should talk to Oracle support about this problem as the core
dump is due to Oracle's driver.

Oracle.jdbc.driver.T4CPreparedStatement causing out of memory exception
I am using oracle spatial 11.2.0.3 g.
I am getting out of memory exception on a process.
I analyzed the heap dump using OOMemory analyzer and figured out oracle.jdbc.driver.T4CPreparedStatement keeping 73% of the heap space.
Is oracle expanding the SPARQL queries in java side or keeping the results in cache.
How to solve it ?Hi,
We will need a re-producible test case (preferably small) to figure out why you are getting out of memory. You can send it to Oracle Support or email me at alan dot wu at oracle dot com.
Jena Adapter does not cache SPARQL query results on the Java side. The T4CPreparedStatement is not even in Jena Adapter's
code path or RDF's code path.
Thanks,

9i jdbc driver change causes problems
Hello all,
I was wondering if anyone had any problems with jdbc when migrating to oracle 9i. We are using timestamps from java which were mapped to dates. In oracle there is a function which takes a date. Now this won't work anymore as the mapping changed. Question is, did anyone use the V8Compatibility flag before? I tried it and it doesn't seem to work. When looking at the jdbc implementation it seems to me that something is not implemented yet.
Any feedback?
Thanks in advance,

Microsoft Jdbc driver for SQL Server memory leak
I'm using Microsoft Jdbc driver and see there's some leak after running application for a while. I'm sure that it's from Jdbc driver because I sitch to Jtds and the issue went away. My question is is there anybody knows which web sites talk about memory leak issue in Microsoft Jdbc driver for SQL Server?

How to find out the cause of "Cannot create JDBC driver"?
A small Java web application constantly runs into a problem of "Cannot of create JDBC driver of class 'org.postgresql.Driver' for connect URL 'jdbc:postgresl://localhost:5432/myapp'". The problem still exists after upgrading the driver. After recycling the server, this problem will be resolved. It, however, will come back after a while.
Any suggestions to solve this problem?
Thanks a lot.jschell wrote:

However since it is an intermittent problem there are only two possibilities
1. You have some code that is written correctly and some that is not.
2. It is a resource not code usage problem. Such as that you are not closing all result sets, statements and connections.Here is related log messages:

If this is a type-4 JDBC driver, it could occur if the JDBC
driver is not in the system CLASSPATH.
If this is a type-2 JDBC driver, it may also indicate that
the Driver native layers(DBMS client lib or driver DLL)
have not been installed properly on your system
or in your PATH environment variable.
This is most likely caused by one of the following:
1. The native layer SO, SL, or DLL could not be found.
2. The file permissions on the native layer SO, SL, or DLL
have not been set properly.
3. The native layer SO, SL, or DLL exists, but is either
invalid or corrupted.

Most likely, the OCI libraries could not be loaded.
Before continuing down this path, is there any reason
why you want to use an OCI based Driver as opposed to the
all Java Oracle thin driver ?There is indeed a valid reason for my choice.
I am currently connecting to the Oracle "Rdb" 7.0 database (located on
VMS) - not Oracle Oracle.
The SQL Service software we're currently using is version 7.1. This
version works well with the OCI8 driver (when connecting to the
database from Windows NT). This version of SQL Service however does
NOT work for the THIN driver (unless we upgrade the SQL Service to
version 7.1.5.5 - which we're not prepared to do so because it is not
stable enough from our previous test/trials). SQLSRV Version 7.1.5.5
works for THIN driver but it will result in uncommitted
transactions/unresolved connection/stopping of listener issues and
there is a need to restart the service from time to time. Oracle has
since confirmed that this is a bug that they have yet to resolve...
So we have to stick to OCI8 (THICK) for the time being. I would really
appreciate it very much if you can tell me the various OCI libraries
that I need to load (in terms of WebLogic Server config file settings
etc..).
By the way I have already installed the Oracle 8 client software on
the NT server (where WebLogic Server is) and I have also set up the
relevant SID (using the Net8 Assistant) that points to the Oracle Rdb
database on the VMS. I have also tried using SQL*Plus to connect to
the database and I can connect properly to the database. But WebLogic
simply doesn't seem to load the software.
Help...

Problems when using absolute() on Oracle JDBC driver
Hi all,
I wrote some codes using JDBC to access a remote Oracle server. After got the resultset, I attempted to use absolute() method to move to a specific row index and got an error. Could anyone please help me to find out the cause and the solution?
Thanks in advanced,
** We have used driver package jdbc/lib/classes.zip in ORACLE 8.1.7
** The total of records in HEFKE000 table > 1000;
** The coding is following:
String url = null;
Connection conn = null;
ResultSet rs = null;
Statement stmt = null;
String query = "select * from HEFKE000";
String dbName = "HE_MI";
String hostName = "NTTD";
String userName = "HOKEN";
String passWord = "manager";
String dbDriver = "oracle.jdbc.driver.OracleDriver";
//Load the Driver
Class.forName(dbDriver);
//get connection
url = "jdbc:oracle:oci8:@NTTD";
//url = "jdbc:oracle:thin:@" + hostName + ":1521:" + dbName;
conn = DriverManager.getConnection (url, userName, passWord);
// It's faster when you don't commit automatically
conn.setAutoCommit (false);
// Create a Statement object so we can submit
// SQL statements to the driver
stmt = conn.createStatement();
// Submit a query, creating a ResultSet object
rs = stmt.executeQuery(query);
// Get the ResultSetMetaData. This will be used for the column headings
ResultSetMetaData rsmd = rs.getMetaData ();
// Get the number of columns in the result set
int numCols = rsmd.getColumnCount ();
int i;
if (rs.next() == rs.isFirst()) {
rs.absolute(100);
boolean more = rs.next ();
while (more) {
// Loop through each column, getting the
// column data and displaying
for (i=1; i<=numCols; i++) {
if (i > 1) {
System.out.print("|");
if (rs.getString(i) == null)
System.out.print("");
else
System.out.print(rs.getString(i));
output.println();
// Fetch the next result set row
more = rs.next ();
** The error:
Exception in thread "main" java.sql.SQLException: Invalid operation for forward
only resultset : absoluteThanks. However, after changed the codes as your suggestion and ran again, I got the following error:
Exception:
java.lang.OutOfMemoryError
<<no stack trace available>>
A note is that, the 'select * from HEFKE000' statement would get around 1,5 millions of records. So, the 'out of memory' above is for client side or for server side?
Thanks, -
Issue using the Eclipse report designer with Derby Client JDBC Driver
All I am trying to do is add a table to a blank report using the Crystal reports Eclipse plugin. The database is connected successfully in Eclipse using the Derby Client JDBC Driver, but when I try to drag a table from the database over to my blank report, I get the following error:

If anyone can help me figure out what I am doing wrong, it would be much appreciated.

When I connect to the Derby database in Eclipse using the embedded driver, I can successfully drag and drop tables to create a report. This driver uses the derby.jar file and has no package sealing violations popping up.
<br/>
<br/>
When specifying a driver for a new derby database in Eclipse, the default Derby client driver expects to use the derbyclient.jar driver file. If I only specify this as the driver file this is the error I get:

The error I initially posted resulted after I added the derby.jar as a driver file in addition to the derbyclient.jar, which I don't think is supposed to be done now that I am thinking about it, but I did it because of the class not found exception above. Is this perhaps simply a bug that it is trying to utilize the derby.jar embedded driver when the client driver should be used instead? Or am I doing something wrong myself?

Embedded OC4J startup time: 29125 ms.I did what Manu suggested with no success. Alternatively, I registered the driver jar with embedded OC4J preferences > global > libraries. Still does not work. Please, note, that when I run JUnit tests against my BC4J application modules with JDBC URL as connection type, everything works just fine. The problem comes while running the JSF application when the application module is using JDBC DataSource as connection type.

I thought it is about JDBC configuration. But when I run JdbcCheckup.java everything works fine. Can anybody help me, please?

I use Java Web Service Developer Pack 1.0 on Win98 SE, database Oracle 8.1.7 is installed on dedicated IBM server (AIX 4.x).
I put these lines in autoexec.bat:
set PATH=C:\Perl\bin\;"C:\j2sdk1.4.0\bin";%PATH%
set CLASSPATH=.;C:\j2sdk1.4.0\lib\tools.jar;C:\j2sdk1.4.0\lib\classes12.zip;C:\j2sdk1.4.0\lib\classes111.zip;%CLASSPATH%
set CLASSPATH=C:\jwsdp_1_0\common\lib\servlet.jar;C:\jwsdp_1_0\common\lib\jasper-compiler.jar;C:\jwsdp_1_0\common\lib\jasper-runtime.jar;%CLASSPATH%
set JAVA_HOME=C:\j2sdk1.4.0I have the same problem. I created a JSP page that uses a class to retrieve database information. I added a main method to the class so I would be able to test it. When I test the class using the main method the method returns all the information from the database. When I try it using Tomcat, I get the following error: java.lang.NoClassDefFoundError: oracle/jdbc/driver/OracleDriver
Does anyone have an idea of what is going on?
My CLASSPATH configuration is the same. -
These resets appear to coincide with a clearing of the cached queries for the DSN from memory, breaking all my sub queries that try to use the initial cached one. I am grasping at straws to discover the reset culprit, the DSN tests always show OK, there is not packet loss at the switch level. If anyone has some suggestions, I am all ears!
The resets are completely random and under no load. My sql 2008 r2 box is set to unlimited connections.
An example of a DSN setup is :
Maintain Connections [x]
String Format [ ]
Max Pooled Statements 100
Timeout 20 Interval 7
Query Timeout 0
Login Timeout 30
CLOB [ ]
BLOB [ ]
Long Text Buffer 64000
Blob Buffer 64000
Validate Connection [ ]
I am running the following :
CF Enterprise 10,0,13,287689
Tomcat 7.0.23.0
Ubuntu 1204 x64
Java VM 20.4-b02
Java 1.6 (Sun Microsystems Inc)
I have seen it suggested to uncheck the maintain connections advanced options but this doesn't seem like a good approach to the problem and will cause more stress on the sql box IMHO.
I have also seen it suggested to enable Validate Connection but documentation on this is a bit sparse...
Here are more examples of the initial reset error and then the subsequent cache related errors :
Database Error Information:
Native Error Code: 0
SQL State: 08S01
Query Error: [Macromedia][SQLServer JDBC Driver]A problem occurred when attempting to contact the server (Server returned: Connection reset).

Thanks in advance to anyone who has a suggestion.Hi, could DBA check MS SQL Server connection logs???
May be server has some limits (for example sessions, memory and e.t.c.) -
Oracle AQAPI causing memory leakage
Good day
I am having a memory leakage on my production server which degrades and eventually dies, the cause is a job that is executed every five minutes which polls the Oracle Queue using the AQAPI. I can see that garbage collector is attempting to finalize() the AQOracleQueue, but this object is waiting on a lock.
My code is as follows:
package com.strysie.aq;
import java.sql.Connection;
import oracle.AQ.AQDequeueOption;
import oracle.AQ.AQDriverManager;
import oracle.AQ.AQMessage;
import oracle.AQ.AQQueue;
import oracle.AQ.AQSession;
*public class QueueDAO {*
*public QueuePayload dequeueMsg() throws Exception {*
AQSession session = null;
AQQueue queue = null;
Connection connection = null;
*try {*

RudiCan only 'guess' since the code is missing that shows how the connection and statement instances are being created, pooled and used.
Your code is not setting the 'wait' option for the dequeue and the default is DEQUEUE_WAIT_FOREVER for a message. So my 'guess' is that an instance of the code you show is 'waiting' for a message and keeping it's connection and statement open and then another thread is trying to use that connection and it is locked or another thread is trying to shutdown the application when the problem appears.
See Dequeuing Messages in the JDBC Developer's Guide
http://docs.oracle.com/cd/B28359_01/java.111/b31224/streamsaq.htm#BABJGBBA
>
•Wait: Specifies the wait time for the dequeue operation, if none of the messages matches the search criteria. The default value is DEQUEUE_WAIT_FOREVER indicating that the operation waits forever. If set to DEQUEUE_NO_WAIT, then the operation does not wait. If a number is specified, then the dequeue operation waits for the specified number of seconds.
>
Try setting the 'wait' option to DEQUEUE_NO_WAIT or to a number of seconds and see if the problem reoccurs.
NOTE: If this problem is occuring because another thread is trying to use this same connection when it is locked it probably means you have a problem in your connection pooling code since it would mean the connection pool is allowing another thread to use a connection that is already being used. -
Problem with clloudscape rmi jdbc driver
I am using Cloudscape rmi jdbc driver, where Cloudscape runs as
a separate server. I am using WL6.1 running on Red Hat Linux
7.1. I defined a Cloudscape connection pool and data source. I
have to start Cloudscape before WebLogic or I get the following
exception:
<Feb 18, 2002 11:39:42 PM EST> <Error> <JDBC> <Cannot startup
connection pool "EStoreConnectionPool"
weblogic.common.ResourceException:
Could not create pool connection. The DBMS driver exception was:
java.sql.SQLException: Connection refused to host: localhost;
nested exception is:
java.net.ConnectException: Connection refused
at RmiJdbc.RJDriver.connect(RJDriver.java:149)
at java.sql.DriverManager.getConnection
(DriverManager.java:512)
etc.
No surprises here: However if I start Cloudscape first and
WebLogic second, I get the following message in Weblogic:

Well, it looks like I'm damned if I do and damned if I don't.
Any suggestions?Actually, it happened because Cloudscape was not properly shut down. Thanks for
responding. I was having some troble with the stopCS script, but its OK now.

Hi Douglass,
The evaluation version of Cloudscape is limited to one concurrent user
per session,
so only one instance of cloudscape can be running at a time. The problem
reported
here can occur if you try to run more than once instance of any product
that
uses Cloudscape -- including WLS or Cloudview. This evaluation version
of Cloudscape
is intended for test purposes only.
This error can also occur on Solaris if you stop the server using ctrl-C
or ctrl-D,
which causes a database lock to remain in place after the server has
stopped.
You can get rid of it by deleting $BEA_HOME/wlserver6.1/samples/eval/cloudscape/data/demo/db.lck
The safest way to stop the server is to use the Admin console or the
SHUTDOWN
command from the command line.

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.
