JDBC Connection Issue in Weblogic 10.3

Hi,
We have upgrade from Weblogic 10.0 to Weblogic 10.3.
We are having the ojdbc6.jar in the server classpath, the JDK being the 1.6. The DB is Oracle 10g.
In an cluster environment, we are getting this error, while passing the connection to an Array Descriptor.
RROR [2009-10-25 04:40:41,700] [] [] - Generic Exception ::
[weblogic.jdbc.rmi.SerialConnection_weblogic_jdbc_rmi_internal_
ConnectionImpl_weblogic_jdbc_wrapper_PoolConnection_oracle_jdbc_driver_T4CConnection_1030_WLStub
cannot be cast to oracle.jdbc.OracleConnection]Kindly help me in providing the solution.
Thanks in Advance,
Sridhar J

Hi. The issue is complicated. First, it seems that you are using a DataSource that has not been
deployed to the cluster, so you are doing JDBC from one WLS server to another before going
to the DBMS. That is slow and problematic. You should deploy the DataSource to the cluster
so every WLS instance has it locally.
The second problem is about your code's cast to an oracle.jdbc.OracleConnection... Are you
sure that code worked in WLS 10.0?

BLOB / CLOB operations using JDBC connections taken from WebLogic 6.0 connectrion pool

Hi..
I need to do some CLOB operations using JDBC connection taken
from WebLogic 6.0 connection pool. Will weblogic 6.0 supports it.?
I am getting errors when trying to do it in normal way .
It seems like ResultSet.getClob() returns an RMI (kind of ) object
instead of the Clob object.
If you have any idea . Pls respond to [email protected]

what will be the host name, port number??
can any one explain

The host name is the name or IP address of the machine running Oracle.
The port number is the port the DBMS is listening on for connection requests.

JDBC connection issue with multiple DBs on same instance

I have two databases on one sql server 2012 instance. One called 'demotime' the other called 'demotime_dev'. how ever when I change in my JDBC connection the DB from demotime to demotime_dev. the connection still remains established with
the demotime, is there any known reason to cause this? does both being on the same instance have anything to do with the problem?

Do your application may send a "USE [demotime]" command to Switch to the database? Do you may use a config file in your application where the database is still pointing to the other database?

JDBC connection issue to 9.2.0.7

Hello,
I am trying to make a jdbc connection to an Oracle 9i database (on AIX, Entreprise 9.2.0.7 - 64 bit) from a linux box.
On the client, I have last jdbc driver available :
jdbc driver name: Oracle JDBC driver
jdbc driver version: 9.2.0.5.0
jdbc driver major version: 9
jdbc driver minor version: 2
db product name: Oracle
db product version: Oracle9i Release 9.2.0.6.0 - Production
JServer Release 9.2.0.6.0 - Production
However, when trying to connect I got the following execption :

Does anyone has an idea oof what is going wrong

Hello,
so here is the solution : in your tnsnames.ora file, the entry name must be the same as the DB SID.

Crystal Report 2008 IDE - JDBC connection issue

Hello,
I'm using Crystal Report 2008 IDE. I've created a report that goes against Oracle 11G database.
I have installed Oracle Instant Client (32 bit) 11.2.0.2.0.
I can establish and Oracle connection via the IDE.
When I attempt to establish a JDBC connection through the database expert wizard, I keep getting JDBC driver not found message.
I've updated my CRconfig.xml specifically the classpath to point to where my ojdbc5.jar file is located.
What else do i need to do in order to establish a JDBC connection?

Hi,
First of all what is the service pack that you are using for Crystal Reports 2008, because Oracle 11g R2 is supported from Service pack 4 onwards in CR 2008.
For JDBC connection with CR 2008 you can have a look at this link might this would help you:

JDBC Connect Issues

So, I have the same project, but thought I would start a new
string for this new issue.
I don't have an Oracle client on my server, and I am trying
to do a connect though a cfscript/createObject to pull Jasper
Reports into Coldfusion.
I guess I was wondering, could I pull all of the Oracle
client drivers, .jar files into my already set up path and access
them or am I missing how that works. Quite often I am... so if this
is the case can you explain it a little?
I am getting a [Macromedia][Oracle JDBC Driver] Error
establishing socket. Connection Refused: connect
and I see that it is a driver issue, so if someone could
point me in a direction and maybe help educate me a bit?
Appreciate everything!
Va.

Sorry I went MIA, I was writing the tech part of a
feasibility study of integrating coldfusion and java... in the
middle of trying to learn how some of this works, but why do things
in order right? :-)
So, the cftry cfcatch caught nothing. I will be checking logs
now. I have no idea where it is falling out. I might post the code
later if I get in the mood to retype it.
I also wrote this little class to test weblogic, which works
for about 15 min then shuts the weblocig server down with an
UnsupportedClassVersion Error... ???
Thanks and take care,
Va.

Sender - JDBC - Connection issue

Hi All,
I see a very strange issue on the JDBC Sender Comm Channel. On the Comm Channel Monitoring, I see it in GREEN. But it is not actually polling the DB table.
Restarted the channel and that did not work.
For now I have created a copy of the comm channel and the copy is working fine for couple days and again the same problem.
I created another copy and second copy is working fine till now.
Not sure what happened.
I think there are some open connections to the DB still hanging in there. I am wondering if there is any way of deleting or closing the open connections.
Thanks in advance.

Hi Naveen,
In your jdbc sender communication cahnnel go to advanced Mode tab --> there is a check box for Disconnect from Database After Processing Each Message. Select this option and give a try. This will make database connection released and reestablished before every poll interval.
Please see this help:

JDBC Connectivity issue

Hi ,
I ran into this issue when I configured my receiver JDBC adapter(synchronous) - I am on XI 3.0 Sp20 (JDK 1.4) and I have installed OJDBC 1.4 as my JDBC driver to connect to an Oracle 10g system.
I have ruled out driver isuues and database issues by writing a small test program to connect the db using the same drivers and the same connectivity parameters like ip/port/sid/id/pwd I used in XI. The program ran fine...
I am really not able to pinpoint the issue and I would appreciate your help..
Error during database connection to the database URL 'jdbc:oracle:thin:@<ip>:1521:<SID>;SelectMethod=cursor' using the JDBC driver 'oracle.jdbc.driver.OracleDriver': 'com.sap.aii.adapter.jdbc.sql.DriverManagerException: Cannot establish connection to URL 'jdbc:oracle:thin:@<ip>:1521:<SID>;SelectMethod=cursor': SQLException: Io exception: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=169870336)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))'
Pls note i did a few negative tests to rule out a few issues ->
1) I changed the server ip on purpose to a wrong one... and the system gave me a different error. So the db server ip is right and working..
2) I changed the password to a wrong one...but I still got the same error as the above..which means the system does not go up to the ID validation step...
3) I gave a wrong SID...and I still got the same error...which leads me to conclude that the adapter is able to point to te right server but not able to hit the db...
Regards,
Arvind R

Hi Arvind,
even though you ruled out problems with the driver, I would suggest to use the Oracle thin JDBC driver version 10.
Maybe there is a problem with the current OJDBC driver you have deployed on your XI. I'm working on an XI 3.0 and we recently deployed version 10 and experience no problems even connecting to clustered Oracle databases. Maybe worth a shot!
Regards
Sven

JDBC CONNECTION POOL FOR WEBLOGIC 8.1 TO ORACLE 8.1.6

I am having problems with my connection pool. When I try to use the classes12 driver I get periodic TNS:connection closed errors and I can not set my initial pool size very high because one will fail with this error. When I try to use the ojdbc14 driver I get a character set not supported error. I am using the nls_charset12.jar file
I am running weblogic 8.1 sp2. I am connecting to an Oracle 8.1.6 database.
Any suggestions would be greatly appreciated.
Thanks
Eric

Hi, thanks for your assistance. Here is the log dump.You should add a 1-second login delay for the pool. (loginDelaySeconds=1).
Oracle can get swamped and ocasionally fail valid connection requests if
too many are sent in a short time, such as when a pool is being initially
populated. This setting will put a delay between successive connection
requests, and should solve the problem.

Linux JDBC connectivity issues

I am having trouble in connecting to 9i RAC via JDBC. The same sample application works well with windows/sun OS. In linux it returns Network Adapter error.I am using ojdbc14.jar to connect to DB.
Appreciate your replies.
Thanks.

Saro,
Do you also have 9i RAC on your Windows/SUN machines -- where you claim this application worked?
Perhaps you could provide the entire error message (and stack trace) you are getting, as well as the section of your code that is causing the error?
Assuming I am correctly guessing what your error message is, "Network Adapter" errors are usually caused because of an incorrect (database connection) URL.
You should find example URLs for RAC if you search this forum's archives.
Good Luck,
Avi.
