I have been trying to create a DataSource on my development machine using Weblogic 12.2.1.3.0 developer install using the admin console and I am getting an exception that I have not encountered before. I have verified that all of the connection information is correct and I can connect to the Oracle Database (v12.1.2) using SQL Developer and an IDE connection but the Weblogic server is not cooperating.
This is the exception that I am getting:
I have also tried creating a DataSource when the EAR file is deployed using descriptors and the DS is created and deployed but the connection pool for the DS cannot be created and the only exception that I am seeing is this:
Connection test failed with the following exception: weblogic.common.resourcepool.ResourceDeadException: 0:weblogic.common.ResourceException: Could not create pool connection for datasource 'StipDS'. The DBMS driver exception was: null
Anyone have any ideas?
Oracle has not been much help at all so far.
check your jdbc connection url, i guess something is missing there. make sure the jdbc driver is present inside lib folder.
I was facing the same issue and able to resolve by replacing the ojdbc6.jar with ojdbc6-2.0.jar from "C:\Oracle\Middleware\wlserver_10.3\server\lib"
Downloaded the jar file from https://jar-download.com/?search_box=ojdbc6++jar
Error log:

i suggest reverting any network changes that might have taken place.
example DNS change in the resolve.conf file

When I try to use the JDBC Connector I'm getting this error when I go to try and send a SQL.
I'm getting a weird error that I don't understand when trying to connect a JDBC request to an Oracle DB.
java.lang.AbstractMethodError: Receiver class oracle.jdbc.driver.T4CConnection does not define or inherit an implementation of the resolved method abstract isValid(I)Z of interface java.sql.Connection.

What's going on here? #jmeter
JDBC driver might be outdated. Does ojdbc8.jar exist in your Jmeter/lib directory?
If not, try downloading it to that directory from the link below. Then, re-start Jmeter and reattempt the connection.
https://www.oracle.com/technetwork/database/application-development/jdbc/downloads/jdbc-ucp-183-5013470.html
You should add ojdbc7.jar to your Test Plan
You can click on Browse and add it, Save Test Plan and restart JMeter
I have created a Service running on Tibco, containing a JDBC-enabled process within it, and tested it successfully. The database server is MySQL, and is hosted remotely. When connecting to the remote DB from the service hosted on my machine, the SQL is executed well, but after building the Tibco EAR file and deploying to another external machine, then trying to access the same remote DB server using the same credentials, the external machine returns the below error upon returning:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'OPTION SQL_SELECT_LIMIT=DEFAULT' at line 1
So, a few questions:
What could be the cause of the above error, given the DB being accessed is the exact same one, using same SQL query, but from different machines?
Is the JDBC driver used for development compiled as part of the packaged EAR file?
Does the JDBC driver being used in a Tibco Process depend on the Tibco service installed or on the packaged EAR file?
Am asking from a learner PoV as am currently picking up Tibco
It looks like jdbc driver issue. You may have different mysql driver version in tibco designer and BusinessWorks.
You don't need to add jdbc driver to your ear package.
Please note that you can specify mysql driver in your package classpath. In tibco Administrator PackageName->Configuration->ServerSettings->Prepend to ClassPath or Append to Class path.
You can also try to copy the driver from your tibco designer(in BW5 it's in \tibco\bw\5.11\lib\
) to the BusinessWorks classpath
I am trying to create a DB2 Data source in weblogic 10.3.6.But I am getting error "cann't load db2 driver". Here I am using Oracle's DB2 (type 4) JDBC Driver. I have provided valid hostname, db2 name and port in connection pool. Also I kept db2jcc4.jar file in $(Domain_Home)/lib folder. But I could not able to figure out reason behind failure. Your help would be appreciated, thanks in advance..
Finally, I managed to get DB2 datasource in weblogic.
Added db2jcc.jar & db2jcc_license_cisuz.jar file in $(Domain_Home)/lib/" directory.
Added jar file in CLASSPATH
set CLASSPATH=${CLASSPATH}${Domain_Home}/lib/db2jcc.jar${Domain_Home}/lib/db2jcc_license_cisuz.jar
I am trying to create a connection pool for a db2 database in glassfish and I'm somewhat new to the entire process. I created the pool yesterday with no problems, I pinged the server successfully and all was well. The next time I start glassfish, my connection pool is gone! After recreating the connection pool with the same settings, the ping is failing with the following error in the server.log:
RAR5099 : Wrong class name or classpath for Datasource Object java.lang.ClassNotFoundException: com.ibm.db2.jcc.DB2ConnectionPoolDataSource
I've tried moving the db2 driver .jar files around to lib/ or lib/ext/ and I've played around with the classpath prefixes and suffixes, but I've had no luck. It seems like glassfish isn't finding the drivers but I can't understand why.
BTW: I'm using OS X 10.6 and I configured the connection pool in a pretty basic way. I also added driverType = 4 to the properties.
Thanks in advance for your help!
You need to have the files db2jcc.jar and db2jcc_license_cu.jar in your classpath. The mentioned lib/ext/ should probably do the trick. The correct classname is probably com.ibm.db2.jcc.DB2SimpleDataSource for use with GlassFish.
I'm trying to deploy a couple of jar files in a code module for an event action in FileNet P8 4.0 (the FileNet server runs on WebSphere 6.1). One of these jars is my custom code, and the other jar is the thin driver for Oracle called ojdbc14.jar (I also tried with ojdbc15.jar), the custom code uses the oracle jar in order to connect to a data source and get a connection using the JNDI name.
When the event action is executed (after a subscription is invoked) the code in my custom module is called OK, the problem occurs when my code needs to load classes from the Oracle jar, I get this cause:
ERROR - Mon Sep 21 16:42:17 UTC 2009 - com.ibm.websphere.naming.CannotInstantiateObjectException: Exception occurred while the JNDI NamingManager was processing a javax.naming.Reference object. [Root exception is java.lang.reflect.InvocationTargetException]

Since I'm deploying the oracle jar with the code module, shouldn't FileNet should be able to find the class? Do you think I need to configure something else?
Thanks in advance.
Is it possible for your application to use WebSphere's own JDBC connection pools? When you set up a pool for a particulr database you get all the vendor-specific drivers installed there.
Generally, all manner of classpath and classloader confisions ensue when you try to place infrastructure code in your own applications. I don't know for certain that this is the case for your situation, but I do find taht staying on the known path in WebSphere tends to give the smoothest results.
I found the problem... somehow the ojdbc14.jar file got corrupted, so even when the classpath was correct and no matter what I tried to fix the problem, the problem was always there.
Thanks for the comments!
