Error creating a connection pool (No suitable driver)

I have just installed WLS6.1 SP3
I try to create a connection with the following parameters
URL = jdbc:oracle:thin@myOracleServer:1521:myOracleSID
DriverName = oracle.jdbc.driver.OracleDriver
every thing else is left as the defaults,
when I click create everything is OK.
I then go to the "Targets" tab and select myserver,
move it to the chosen column and click apply.
I then get the error
<Error> <JDBC> <Cannot startup connection pool "myCP" No suitable driver>
I looked at the doc edocs.bea.com/wls/docs61/jdbc/thirdparty.html
Under the section "Setting environment for your third party driver"
it implys that if your using sybase jconnect or oracle thin drivers
you do not need to do anything else.
I looked in the weblogic.jar file and the OracleDriver.class file
is there under oracle\jdbc\driver.
the CLASSPATH=.;.\lib\weblogic_sp.jar;.\lib\weblogic.jar
I would have thought that the driver class in the jar file
would have be picked up given the path & classname match the
driver name enter in the console.
Any ideas on how to fix this problem?

Hi Robert,
Looks like colon is missing after jdbc:oracle:thin. The url should be
jdbc:oracle:thin:@myOracleServer:1521:myOracleSID

Error in creating a connection pool (No suitable driver)

I try to create a connection pool in a Weblogic server 7.0 with the following config:
URL:
jdbc:oracle:oci9:@db_name
Driver Classname:
oracle.jdbc.driver.OracleDriver
Properties(key=value):
user=user_name
password=user_password
dll=ocijdbc9
server=db_name
protocol=oci
my computer (windows 2000) has installed Oracle 9i client, and this connection
pool will connect to Oracle 8i server. Besides, I have config classes12.zip in
the "classpath" and ocijdbc9.dll in the "path" environment variables.
Can Oracle 9i driver connect to a Oracle 8i server? Or there is other problems?
Thanks in advance.

Please try URL = jdbc:oracle:oci8:@db_name... that should be fine.
Yes, you can connect to 8i oracle database using 9i driver.
Also, make sure you have classes12.zip in classpath and ocijdbc9.dll in path.
Thanks,
Mitesh

Error: Creating a Connection Pool: issue with valid transaction levels

Server: SunOS 5.8 Generic_117350-27 sun4u sparc SUNW,UltraAX-MP
App Server: Sun Java System Application Server 8.2
Jar: ojdbc14.jar
Datasource Classname: oracle.jdbc.pool.OracleConnectionPoolDataSource
Resource Type: javax.sql.ConnectionPoolDataSource
[Issue]
Using /SUNWappserver/lib/ojdbc14.jar, when I create my connection pool in Sun Java System Application Server 8.2, I return the following error each time I try to start the domain:
[#|2006-07-28T14:53:56.169-0500|WARNING|sun-appserver-pe8.2|javax.enterprise.resource.resourceadapter|_ThreadID=11;|RAR5117 : Failed to obtain/create connection. Reason : The isolation level could not be set: READ_COMMITTED and SERIALIZABLE are the only valid transaction levels|#]
When I change the value to "SERIALIZABLE" in my domain.xml file, I receive the following error in my server.log:
Caused by: org.xml.sax.SAXParseException: Attribute "transaction-isolation-level" with value "SERIALIZABLE" must have a value from the list "read-uncommitted read-committed repeatable-read serializable ".
So, I'm stuck!
I can't use the values READ_COMMITTED or SERIALIZABLE since the valid values are "read-uncommitted read-committed repeatable-read serializable ".
Case sensitivity matters.
Any thoughts or help would be greatly appreciated.
Thanks,
--Todd

The Oracle JDBC accepts TRANSACTION_READ_COMMITTED and TRANSACTION_SERIALIZABLE isolation levels.
Example:
connAttr.setProperty(“TRANSACTION_ISOLATION”, “TRANSACTION_SERIALIZABLE”);
I'd check with the Apps server folks.

Error creating a connection pool to DB2 with the weblogic 8.1 driver

I am trying to create a new connection pool with using the weblogic 8.1 (non XA driver (weblogic.jdbc.db2.DB2Driver)). When I create the pool one of the steps is to test the driver configuration and it fails with this step.
I get the following error:
[BEA][DB2 JDBC Driver]The databaseName connection property is not valid when connecting to Host Operating Systems.
We are going through IBM's DB2 connect gateway (version 8.x) to connect to a DB2 database running on Z/OS.
Here are my connection parameters:
Driver Classname: weblogic.jdbc.db2.DB2Driver
url: jdbc:bea:db2://db2cont2.arrow.com:3700

MattHi Matt. Unfortunately DB2 is different on differnet OSes. For
DB2 on OS/390, z/OS, iSeries, and AS/4001, the URL is like this:
jdbc:bea:db2://db2_server_name:port;Location=db2_location;CollectionId=your_collectionname
Try removing the serverName property and the databaseName, and
change your URL to
jdbc:bea:db2://db2cont2.arrow.com:3700;Location=db2_location;CollectionId=your_collectionname
where you would change 'db2_location' and 'your_collectionname' as appropriate.

marcoHi. Read the weblogi startServer script, and the startWLS script it calls. These
scripts build up a string which is added to the java commandline that starts
the server, with an argument -classpath ....... Unless the driver shows up there,
the server doesn't see it.
However, we already include a version of the oracle thin driver. It may not be
the best (it's old), so you will want to make sure you version gets in to the classpath
argument ahead of our stuff, but the old driver would have been invoked...
Therefore, I suspect your URL is not exactly correct. Please verify that this exact URL
works in a simple standalone JDBC program using the driver you want, without any
weblogic code in the picture.
thanks,
Joe

How to create the connection pool using jdbc20 driver?

Hi all,
My configuration is WL4.5 SP5 + jdk1.2.2+WinNT+ Oracle thin driver
8.1.6.
It is creating the connections with weblogic.jdbc.pool.Driver, whereas i
want the connections in the pool to be created with jdbc20 driver. This
how my pool definition is defined.
weblogic.jdbc.connectionPool.PoolName=\
url=jdbc:oracle:thin:@<IP address>:<Instance>,\
driver=oracle.jdbc.driver.OracleDriver,\
loginDelaySecs=1,\
initialCapacity=1,\
maxCapacity=40,\
capacityIncrement=2,\
allowShrinking=true,\
shrinkPeriodMins=5,\
refreshMinutes=10,\
testTable=dual,\
props=user=XXXX;password=XXXX
The reason is I want to use BLOB's. I have a message posted in jdbc news
group with the exception i got. But since this more of a environement
issue i am posting it here.
Any help is appreciated,
Thanks
John

Here is the correct pool definition.

Problem with creating Connection pool and JNDI, driver is not detected

Hi,
I have an issue with creating Connection Pool and JNDI.
I'm using:
- JDK 1.6
- OS: Linux(ubuntu 8.10)
- Netbeans IDE 6.5.1
- Java EE 5.0
- Apache Tomcat 6.0.18 Its lib directory contains all necessary jar files for Oracle database driver
- Oracle 11g Enterprise
My problem is that the Oracle database driver is not detected when I want to create a pool (it works pretty well and is detected without any problem when I create ordinary connection by DriverManager)
Therefore after running:
InitialContext ic = new InitialContext();
Context context = (Context)ic.lookup("java:comp/env");
DataSource dataSource = (DataSource)context.lookup("jdbc/oracle11g");
Connection connection = dataSource.getConnection();and right after dataSource.getConnection() I have the following exception:

, but no solution.
As many suggest, I also tried to put context directly in the server.xml (instead of my application context) and referencing it by <ResourceLink /> inside my application context but it didn't work and instead it gave me the following message:
org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '   ' for connect URL 'null'
Has anyone succeeded in creating a connection pool with JNDI by using Tomcat 6 or higher ? If yes, could kindly explain about the applied method.
Regards,

Hello again,
Finally I managed to run my application also with Tomcat 6.0.18. There was only two lines that had to be modified
in the context.xml file (the context of my application project and not server's)
Instead of writing
<Context antiJARLocking="true" path="/WebApplication2">
    type="javax.sql.DataSource"
    factory="org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory"
</Context>we had to write:
<Context antiJARLocking="true" path="/WebApplication2">
    type="oracle.jdbc.pool.OracleDataSource"
    factory="oracle.jdbc.pool.OracleDataSourceFactory"
</Context>- No modification was needed to be done at server level (niether server.xml nor server context.xml)
- I just added the ojdbc6.jar in $CATALINA_HOME/lib (I didn't even need to add it in WEB-INF/lib of my project)
- The servlet used to do the test was the same that I presented in my precedent post.
For those who have encountered my problem and are interested in the format of the web.xml and context.xml
with Tomcat 6.0, you can find them below:
Oracle server: Oracle 11g Enterprise
Tomcat server version: 6.0.18
Oracle driver: ojdbc.jar

Fatal error while filling connection pool

I was not getting a connection to an Oracle database and I was getting the following error in cms.log: "FATAL Connector - Unable to create connection pool for T_Orbis_Oracle: Fatal error while filling connection pool for jdbc:oracle:thin:@MESDB:1521:ASPENB21" where T_Orbis_Oracle is the xMII link name and the database ASPENB21 is on server MESDB. I changed the database username in the link to SYSTEM and I then got a connection and a Created Connection pool message in the log. I then changed back to the username which originally was giving the error and it now also gave me a successful connection. I am now worried that there is an issue in the background which is gradually building up and will begin to fail again as previously. Can anyone explain what is causing this problem and suggest how I can correct it? Thanks, John.

John,
Check you have installed the JDBC driver ojdbc14.jar (works for both 9 and 10).
Also check the server package:
MII 11.x--->ServerPackage com.lighthammer.Illuminator.connectors.IDBC
MII 12.x--->com.sap.xmii.Illuminator.connectors.IDBC
Carefull when you set up the string because some oracle databases have servicenames instead of SID, and the url was different if you use them instead of the SID.
For services names the url is jdbc:oracle:thin@host:port:SID
Also check your Network firewall between MII and DB and ports too.
Oracle9i installs with a number of default accounts.You must unlock all other accounts before using them. Oracle recommends changing all user passwords immediately after installation.

Problem creating a connection pool for mssql server

Hi
i downloaded the microsoft type 4 driver for JDBC and i have installed it. now i am trying to create a connection pool for MS Sql server but each time i ping i keep getting an error telling me
Operation 'pingConnectionPool' failed in 'resources' Config Mbean. Target exception message: Connection could not be allocated because: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket
please can someone help out on this

I assume that you installed the driver correctly. You did go into the app sever admin and set the JVM path? You do this by going to Application Server | JVM Settings | Path Settings and putting in an entry for Classpath Prefix.
If that is done and it's not something basic like your database isn't turned on, then it must be your settings. To to Sun's site and search for dbping. http://developers.sun.com/prodtech/appserver/utilities/dbping/dbping_overview.html
Deploy this program and run it. It is a very simple tool that lets you test different property settings. Play around with different settings until you get a ping.
If that doesn't work post your connect pool settings.
Good luck

The details for my database are as follows
database name : mydb
database server : 173.24.24.1
database port : 1521
username : myuser
I would appreciate if you can provide me the following details to be entered in
weblogic console for creating the connection pool

Error using mySQL connection Pool

I see the following error when my application uses the connection pool - can anyone explain this ?
INFO: CORE3282: stdout: =======================>ERROR :com.sun.enterprise.repository.J2EEResourceException
WARNING: CORE3283: stderr: at com.sun.enterprise.resource.IASNonSharedResourcePool.initPool(IASNonSharedResourcePool.java:416)

Hi,
You have used dataSourceName property while creating a connection pool.This property is not required to be set while creating a connection pool for MySql
Use the following properties:
<property name="serverName" value="<name of server>"
<property name="port" value="<port number>"
<property name="DatabaseName" value="<your db name>"
<property name="User" value="<user name>"
<property name="Password" value="<passwd>"

Create A Connection Pool In the ServletContextListener

The Specification says that we should create the connection pool in the ServletContextListener. I have the code for creating a connection pool (see below). How do I create it in the ServletContextListener?
import java.sql.Connection;
import java.sql.SQLException;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.sql.DataSource;
public class DBConnection
   public static Connection getDBConnection() throws SQLException
      Connection conn = null;
      try
         InitialContext ctx = new InitialContext();
         DataSource ds = ( DataSource ) ctx.lookup( "java:comp/env/jdbc/MySQLDB" );
         try
            conn = ds.getConnection();
         catch( SQLException e )
            System.out.println( "Open connection failure: " + e.getMessage() );
      catch( NamingException nEx )
         nEx.printStackTrace();
      return conn;

I use the connection pool feature provide by the server I use. Is this what I should do? Please confirm.
import java.sql.Connection;
import java.sql.SQLException;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.sql.DataSource;
import javax.servlet.*;
public class CreateResources implements javax.servlet.ServletContextListener
     public void contextInitialized(ServletContextEvent sce)
          public static Connection getDBConnection() throws SQLException
               Connection conn = null;
               try
                    InitialContext ctx = new InitialContext();
                    DataSource ds = ( DataSource ) ctx.lookup( "java:comp/env/jdbc/MySQLDB" );
                    try
                         conn = ds.getConnection();
                    catch( SQLException e )
                         System.out.println( "Open connection failure: " + e.getMessage() );
              catch( NamingException nEx )
                    nEx.printStackTrace();
              return conn;
     public void contextDestroyed(ServletCotnextEvent sce)
}

How to Create a connection pool in OSB java callout

Dear Team,
In our project, we need read some data from DB, and do corresponding operation. currently, we need setup the connection first, execute the SQL, and close the connection.
But the concurrency of call is very high, is there a way to create a connection pool, then we can use the connection pool to get the connection and execute the SQL, then return the connection to the pool.
if connection pool is not available, is there any way to create the connection outside the java callout, that we can just execute the SQL in java callout.
The OSB version is 11.1.1.6.0
Thanks.
Best Regards,
Raysen Jia

Hi Team,
Thanks for your help.
What I need is not only the db connection, may be other kind of things, such as read configuration from file...
If I write the code in java callout with static java method to create and close the connection, each time when request come in, OSB will create a new connection (or read the file), I think it's not the best practice to do this kind of work.
I think the weblogic is running in JVM, is there any way we can define variables or new object in the JVM directly?

A question about creating a Connection pool that uses Oracle JDBC

Dear all,
I have an issue with creating a connection pool within a web application in order to be used by several servlets. I appreciate if you could kindly give me a hand.
I'm using:
Web server: Apache-tomcat: 6.0.18
Oracle Database 11g Enterprise: 11.1.0.6.0 - Production
Operating system: Linux (ubuntu 8.10)
IDE: Sun Netbeans
Oralce JDBC Drivers: 11.1.0.7.0-Production (ojdbc6.jar and orai18n.jar)
JDK 1.6
Usually, just for creating a connection to my database (without using a connection pool), I proceed in the following way:
String dbURL = "jdbc:oracle:thin:@localhost:1521:database01";
String username = "scott";
String user_password = "tiger";
String userSqlQuery = "SELECT * FROM mytable";
Connection connection = DriverManager.getConnection (dbURL, username, user_password);
Statement statement = connection.createStatement();
statement.executeUpdate(query_text);This works pretty well allowing to communicate with my oracle database. By this method I have run several projects
with different queries (SELECT, INSERT, UPDATE, DELETE ,etc.) and each time it worked without any problem and
returned the result of the query. Therefore I think that there is no problem with JDBC drivers
However, when I want to create a connection pool, it seems that the lookup method cannot locate Oracle JDBC drivers. That is,
try
     InitialContext ic = new InitialContext();
     Context envContext = (Context)ic.lookup("java:/comp/env");
     dataSource = (DataSource)envContext.lookup("jdbc/oracle11gEnterprise");
       Connection connection = dataSource.getConnection();
catch (Exception e)
     e.printStackTrace();
}Just after calling dataSource.getConnection() the java.lang.NullPointerException is thrown.
Any idea?
Thanks in advance,
And for your information, here are context.xml and web.xml files for my project
Here is my context.xml
