Query TImeout with ORACLE JDBC driver

I want to halt an execution of query if an query takes more than specified time. Not only the query should be cancelled but the error should be thrown at client. I am using ORACLE 11g JDBC driver.
I have used statement.setQueryTimeout() for the same. Moreover, my application is an OLTP system handling thousands of calls per second and one call is of 4 to 5 queries. Can anyone explain whether querytimeout will work in this case and its drawbacks if any.

Dear user10366531,
Your question about setQueryTimeout() has been already disscussed in this topic (Setup "QueryThreshold" parameter
(Chris Jenkins aswered).
Best regards,
Gennady

Have you tried the drivers shipped with Oracle9i Db R2? they should work against JDK 1.4

HELP!!! Cannot deploy J2EE application with Oracle JDBC driver...

Hi,
I am writing a J2EE application which (in theory, at least)
connects to an Oracle 9i database.
I have written a simple Java test app utilising only the
java.sql package classes (e.g. Connection, ResultSet) to directly
connect to the database. As long as the classes12.zip is in the
CLASSPATH it works fine.
Now I have written an Enterprise application (SessionBean,
Remote and Home interface and Client) which I am attempting to
deploy via deploytool.
If I include just the client jar and EJB jar in the application
it deploys okay but when I run the application (using runclient)
it produces the following error:
java.lang.NoClassDefFoundError: oracle/jdbc/OracleDriver
(It is nested within other error output but that is the core
issue).
However if I try to include the JAR libraries into the app
(classes12.jar and nls_charset.jar from $ORACLE_HOME/jdbc/lib),
then I get the following output from deploytool when I hit the
"deploy" (or "redeploy") button:
Deployment error: invalid entry compressed size
(expected 14411 but got 14580 bytes)
Can someone please tell me what is going on???
How can I deploy the J2EE application including the Oracle
JDBC Driver???
My only other option at the moment is to place all the function-
-ality in the client and not use the J2EE framework.
Any help is greatly appreciated.

OK Ben,
I admit I'm a bit confused. Let me see if I understand where you're
coming from.
You have written a J2EE application that includes a session bean,
correct? If so, your session bean needs to be deployed to an EJB
container. What container are you using? The Oracle 9i database
has an embedded EJB container which (theoretically) you can use.
However, as far as I know, Oracle recommends you use OC4J as the
EJB container. So again I ask, what EJB container are you using?
If, as you say, you are new to EJB, then I think you should
immediately start working wiht OC4J as your EJB container.
Did you look at the tutorial link I gave in my previous post? It
explains -- step by step -- how to create, deploy and run a J2EE
application using OC4J as the EJB container. It also has links to
introductory material for people without little knowledge of J2EE
and EJB.
I have 9iAS Enterprise Edition and 8.1.7.1.0 database server (and
OC4J) installed on my SUN machine. I cannot find any of the
utilities you mention -- "j2eeadmin","runclient" or "deploytool".
What Oracle software have you installed? What are the versions?
What platform are you using?
A J2EE application (according to the specification from SUN)
consists of modules. A module can either be a client module or an
EJB module. A client module can either be a java application client
or a web-based client (servlet or JSP). A J2EE application usually
contains one client module and one EJB module. A J2EE application
needs to be deployed to a J2EE container.
Hopefully the J2EE picture is becoming clearer. I think you need
to read some introductory material regarding J2EE if you intend
to become proficient at it.
I feel that you are under the impression that a J2EE application
is a glorified JDBC application. It isn't (as far as I'm aware).
Good Luck,
Avi.

Problems with Oracle jdbc Driver

Hi... I'm trying to connect to my Oracle Database and I get the folowing error:
"package oracle.jdbc.driver does not exist"
I have installed Oracle 9.1.0.2 Database...
The value of the Classpath variable is:
".;c:\oracle\ora92\jdbc\lib"
What could be the problem???...
Thanks in advance.-
Alberto.-

Are you building your application from the command line? Or using a GUI? GUI's will frequently overwrite your CLASSPATH environment variable...

[Macromedia][Oracle JDBC Driver]Numeric overflow

I am moving from CF 6.1 to CF 9 using Oracle 9i. I get the following error when I use cfstoredproc to call a procedure in a package: [Macromedia][Oracle JDBC Driver]Numeric overflow. In spite of throwing the error, the stored procedure seems to execute properly. Has anyone encountered this problem?

I cannot consistently replicate the problem. Values that work the first time may not work the second time. The data is always entered in the database, but sometimes an error message is thrown regardless of the fact that the data was entered into the database. Calling the procedure with PL/SQL works every time. Here is a dump of the info. from cfcatch:

Is Oracle JDBC driver thread safe

Is the Oracle JDBC driver thread safe?

Seems that this is not totally true.
We have a Problem with Oracle JDBC driver 9.2.0.5.0 (thin)
Using an IBM JDK 1.4
Szenario:
Thread 1 access to a CLOB via
ResulSet.getCharacterStream(int)
Thread 2 normal access via some select and
ResulSet.getString(int)
(Both using the same connection)
The following threads appear to be in a circular deadlock.
Further information can be found by looking in the Overall Thread Analysis
section of this tool.
Multi-threaded deadlock 1:

It seems that the access to the CLOB needs another,
internal SELECT to the Database and this way
TTC7Protocol and OracleConnection lock out each other.
This only happens on a true multiprocessor machine.
We tried to reprodcue it on a Single Processor
and some HyperThreading Machine but had no real sucess.
Now where can I sumbit this as a Bug ?

Petstore throws populateServlet error with Oracle thin driver

I believe that you do not have weblogicaux.jar in your classpath.

In Trouble with the Oracle JDBC Driver version - 10.1.0.5.0

Hi !
Without any problems i'm using the Oracle JDBC Driver version - 10.1.0.3.0 to access to the
Oracle database (Oracle Database 10g Release 10.2.0.1.0 - 64bit Production).
But exchanging the JDBC Driver 10.1.0.3.0 to 10.1.0.5.0 brings up the following problem:
the statement
con.prepareStatement(sql, resultSetType, resultSetConcurrency, resultSetHoldability)
(with parameters resultSetType = 1003, resultSetConcurrency = 1007, resultSetHoldability= 1)
returns null !
while using the Oracle JDBC Driver version - 10.1.0.3.0 the statement (with same parameters)
returns a correct PreparedStatement.
Every hint or idea is welcome.
Best regards,
Claus

Duplicate post:
In Trouble with the Oracle JDBC Driver version - 10.1.0.5.0
Claus,
Pardon me if I am stating the obvious, but why don't you use the 10.2 JDBC driver with your 10.2 database? The driver is part of the database distribution. Otherwise, you can download the driver from the OTN Web site.
Good Luck,
Avi.

Does oracle jdbc driver 9.0.1 work with sdk 1.4?

Hi All Experts...
Does oracle jdbc driver 9.0.1 work with sdk 1.4.1? Ever since i have moved to 1.4 i am having problems. I keep getting the No Suitable Driver error or NoClassDefFoundError. I have everything in the classpath and i have also tried command line but to no avail. The JVM just refuses to pick up the classes12.zip file from the classpath.
The oracle site mentions that the 9.0.1 driver is for jdk 1.2 & 1.3 but it does NOT mention that it is NOT for 1.4.1. The site very explicitly mentions that the 9.2 driver is for 1.4.1. SO i am a little confused.This question may be stupid, but nevertheless,If i have to upgrade my driver from 9.0.1 to 9.2 then does that mean that i have to upgrade my DB as well?
Experts..please help.. THanks

Thanks a lot, as usual, MOD.
Now only if i can get my JVM to pick up the classes12.zip file from the classpath. I dont know if you read my previous posting today.

Deploying .jar with Oracle JDBC thin driver

I was just experimenting with a Java application that uses an Oracle JDBC driver. It runs fine in JDeveloper. However, when I deploy it to a .jar and run it from a Windows XP Command Prompt I get:
Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.
C:\xxx\deploy>java -jar testme.jar
Exception in thread "main" java.lang.NullPointerException
at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java)
at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
Is there anything special I need to do to the Deploy file? I tried including the the classes111 manifest to no avail.

Hi,
Ensure that the JVM being used is the same or at least same spec level that you built your project. JDeveloper 9.0.3 uses VM's compatible with 1.3.1 by default. It is possible that your OS path has another VM that the cmd line defaults to. Use a java -version to check this.
Also ensure that you include Oracle JDBC as a project library and when you go to create a JAR file (either simple archiver or a Client Jar) that you include the Oracle JDBC libraries from the Dependency Analyzer. I assume this is probably the missing step since your are deploying to a Jar and not an app server where you would put the driver libraries in the app server classpath.

Hanging problem with Oracle JDBC thin driver

Hi. We have an application running on top of WLS 6.1 accessing Oracle 8I with oracle's
JDBC thin driver. Under stress testing, it appears to hang sometimes. Thread dump
shows that many threads seem to be stuck at the same line of code in JDBC driver
(at oracle.sql.NUMBER._isPositive(NUMBER.java:2882)). Has anyone run into similar
issue? Any help is much appreciated.

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.

[Oracle JDBC Driver]This driver is locked for use with embedded application

Hi
I installed Sun Java Studio Enterprise 8, and am trying to connect to my Oracle database using the attached tutorial code.
The code compiles fine, but I get the following error whenever I run the file: [Oracle JDBC Driver]This driver is locked for use with embedded application
I don't understand what is happening.
Using the Runtime navigation panel on the upper left of the IDE screen, I can right-click and connect to the database, and navigate database files, using the Oracle JDBC Driver that came with JSE8.
Name: Oracle Driver
Driver: com.sun.sql.jdbc.oracle.OracleDriver
Database URL: jdbc:sun:oracle://JAZZPUP:1521;SID=REPO
If the driver is installed, and can be used to connect to a database by right-clicking on the database definition in the Runtime panel, why can't I connect to it just using java code in the IDE. I would expect both methods to work or to fail, not one of each using the same IDE.
Many thanks and take care,
Shayne

There are two similar threads:

http://swforum.sun.com/jive/thread.jspa?threadID=51057&messageID=188210
To summarize - the DataDirectDriver that is shipped with the IDE seems to be locked to be used inside the IDE only because of some licensing issues etc..
That's weird, I agree. I will raise a question on reasons for such a behavior.
The solution would be to use Oracle's own driver, that is distributed at no charge from their web site - http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html

JDBC logging disabled with Oracle thin driver

Hi,
I am trying to turn on JDBC logging through the weblogic console application (WL
6.1 with CMP). In the jdbc log file I do not see the SQL statments.
It looks like logging is somehow disabled (check one of the logs statements below)
by some means. Any ideas, I am making use of oracle thin driver.
Thanks

Mohit,
Remove oracle/jdbc/driver/OracleLog from classes12.zip, and it should
work (it needs to pick up only this class from weblogic.jar).

Which Oracle JDBC Driver to use with WSAD 5.1.2?

Hi,
I will appreciate if someone could help me with:
1) Whether I should select "Oracle JDBC Driver" or "Oracle JDBC Driver (XA)" as the JDBC Provider Type. The rest in the list (Thin & oci8 ) are deprecated.
2) When I go to create a datasource, for either of the above JDBC provider type, I get the options:
- User defined JDBC provider
- Oracle JDBC provider
- Oracle JDBC Thin Driver
- Oracle JDBC oci8 Driver
Why do I have the Thin and Oci8 option here, when those were shown as deprecated under JDBC Provider Type?
Please help to clear up this confusion.
-Nimmi

This is what I did for my DS settings
1. select Oracle JDBC Driver
2. set Classes12.jar in Websphre classpath - (Oracle thin driver)
3. create DS with option User defined JDBC provider
means I have added Thin driver provided by Oracle , instead of deprecated Thin driver from IBM.
