Can I create connection pool by oracle oci driver?

Can I create connection pool by oracle oci driver?My weblogic's version is 6.1 sp2 and oracle is 9.0.1.2.
I have some trouble with connection pool created by weblogic jDriver.
I try to read Timestamp from table and I always get the exception.It told me that ORA-00932: inconsistent datatypes.
So I created another pool by oracle thin driver and everything was right.Then I created other pool by oracle oci driver,but something were wrong. 'Could not create pool connection. The DBMS driver exception was:java.sql.SQLException: ORA-06401: NETCMN:Invalid driver designator'
The oci pool's parameters are below lines.
url: jdbc:oracle:oci:@COCO
Driver Classname: oracle.jdbc.driver.OracleDriver
Properties: user=scott;password=tiger;protocol=oci
If I get connection directly,don't use connection pool,I can get right connection.But why didn't I create pool by oci driver?Maybe weblogic7 or weblogic8 will work good?

Hi Joe,
I am also trying to create a connection pool using Oracle Oci XA. Weblogic
type 2 oci threads hanging on native calls and suggested to go for thin drivers.
But we want to try with Oracle Oci drivers.. Can you please tell us how to
create a conn pool using Oracle Oci.. Just the driverclass and url is enough
or need any classpath settings etc..
Thanks in advance for your quick reply.Hi. As far as driver properties, just use what Oracle says to. Any pool properties
that we recommend for XA would still apply. Note that Oracle themselves recommends
the thin driver over their OCI one:

Error in creating Connection Pool using Oracle Thin Driver

Hi,
I am trying to create a connection pool in WS 5.1 with sp #6 using Oracle Thin Driver (oracle.jdbc.driver.OracleDriver) on a Sun box. But I am able to create the pool using weblogic.jdbc.oci.Driver. I get an DBMS Driver exception when I use thin driver. I have LD library path and weblogic class path set correctly. WL shows the following exception :
weblogic.common.ResourceException: weblogic.common.ResourceException:
Could not create pool connection. The DBMS driver exception was:
java.sql.SQLException: Io exception: The Network Adapter could not establish the
connection

Any help on this is greatly appreciated.
Thanks,

Hi Ramu,
Please post your connection pool setting here. You might have missed some
port/server info. The driver is unable to connect to the db server here.

Did you setup the JDBC library classpath correctly?
For me, e.g. Oracle 7.3.4, the classpath should be:
export CLASSPATH = /oracle7.3.4/jdbc/lib/classes.zip:%CLASSPATH%
Noted that the JDBC classpath must be the first classpath element in

Hi Joe !
I didn't get what you would like to point out. Actully, I am using same config.,
but not to disclose the info. I gave you @test and username/password xxx/xxx.Ok. Now, assuming your pool looks like what I showed, the issue is probably
that there are multiple Oracle driver zips around, and your standlaone program
is using a different, newer, better one than the server. Our weblogic jar files
include a classes12.zip Oracle thin driver, but there are multiple versions of
classes12.zip, and the latest from oracle is better than the one we sealed into
our packaging. Please use jave -verbose to identify exactly which Oracle sip file
you are using in the successful case, then make sure this zip file comes before
any weblogic stuff in your weblogic server's classpath, so we'll use the same
driver. This should work. Edit the script you sue to start weblogic to verify
the classpath does end up with the oracle driver ahead of all weblogic stuff.

Now we need to simplify the problem. Please make a simple 15-line

Java program like you'd find with the Oracle driver's examples, with
no
weblogic code in the picture. Just make a JDBC connection using Oracle's
driver, and show me that code. Then I can translate that into a pool

Oracle OCI driver stops working after a while of disuse

I am using wl server 8.1, oracle oci driver (oracle 9i client), on solaris.
When i create a connection pool using the oci driver, it connects, and i
test it, and the tests run fine.
The Application works for a few days. Then eventually after disuse, say over
the weekend, I get exceptions in the log (the message is at end of email).
This is because it gives me a sql exception saying it cannot resolve the
service name. The database is up and running, confirmed.
I tried testing the connection pool manually through the console, and it
failed with the service name exception. But it would connect fine when i
used sqlplus to connect to the databse, using the same service name.
Why does this deteriorate over time? Is there a specific test that would
prevent this from happening?
Once i restart the weblogic server, the connection pool connects fine. But
this is not a solution, since I can't be restarting the server all the time.
Any one got any ideas?

I am using wl server 8.1, oracle oci driver (oracle 9i client), on solaris.
When i create a connection pool using the oci driver, it connects, and i
test it, and the tests run fine.
The Application works for a few days. Then eventually after disuse, say over
the weekend, I get exceptions in the log (the message is at end of email).
This is because it gives me a sql exception saying it cannot resolve the
service name. The database is up and running, confirmed.
I tried testing the connection pool manually through the console, and it
failed with the service name exception. But it would connect fine when i
used sqlplus to connect to the databse, using the same service name.
Why does this deteriorate over time? Is there a specific test that would
prevent this from happening?
Once i restart the weblogic server, the connection pool connects fine. But
this is not a solution, since I can't be restarting the server all the time.
Any one got any ideas?
-AyanHi. Is there a firewall between the weblogic server and DBMS? There is
a problem with OCI losing connectivity to the DBMS. OCI may be keeping
a socket open as long as the process (weblogic) is running.

Place the bin/oci815_5 in the weblogic installation in your path. You can set this path in
your startweblogic script. If you are on a unix environment, set this in the LD_LIBRARY path.

How dynamically create connection pool and Datasource

Hi
How I can dynamically create a connection pool and Data source in Oracle 10g Application server. In our J2EE application the user will be login with db user name, password and database name. I want to create connection pool and data source on the fly while login the user with database name. I our application we have access approximate 80 Databases. so my approach is given bellow
1) Planning to create 80 connection pools and 80 Data sources so when user logs in while selecting the db name i will call the appropriate data source and create the DB connection. Is there any limitation to create number of data sources in oracle app server?
2) Create DB connection with out using connection pool and data source. But i am not prefer this approach coz we need to handle some transaction in our application.
Kindly throw some light on managing connection pool programmatically or in application run time.
I would really appreciate if any one can provide any links or any inormation on this issue.
Thanks in advance.

Kindly let me know is there any drawbacks to create 80 Data Sources to connect 80 database in Oracle 10G App server and each data sources should have one connection pool. so i need to create 80 connection pool. Please let me know is this right approach or any work around to create Data source on fly for each request for corresponding database.

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:
org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot load JDBC driver class 'oracle.jdbc.OracleDriver'

, 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
IDE: Netbeans 6.5.1
The context.xml file of the web application
<?xml version="1.0" encoding="UTF-8"?>
