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JDBC driver might be outdated.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.

You should add ojdbc7.jar to your Test Plan
You can click on Browse and add it, Save Test Plan and restart JMeter

I am trying to query couchbase from within JMeter in mac.
I downloaded connector-couchbase-10.0.2.jar. I put the jar file in the jmeter lib folder. I have the couchbase URL of my org and I can connect to it and query it directly.
I put the couchbase uRL in the jmeter JDBC Connector Configuration element. However, it is not clear what to put in the JDBC Driver class.
I keep getting the error message "“Cannot load JDBC driver class”. Any idea what should I do? Is there a way to add the couchbase connector through the JMeter Plugins Manager?
I appreciate any clues to this.
Add also connector's dependencies to JMeter's lib folder
Dependencies teiid-api, teiid-common-core, jboss-connector-api_1.7_spec, couchbase-api, java-client,
Use JDBC Driver as cdata.jdbc.couchbase.CouchbaseDriver, see couchbase JDBC docs
Provide the JDBC URL. For example:
jdbc:couchbase:User='myusername';Password='mypassword';Server='http://couchbase40'
or
jdbc:cdata:couchbase:User='myusername';Password='mypassword';Server='http://couchbase40'
I am trying to run the JMeter load test in VSTS. As this load test runs successfully on my local machine, but displays an error message while using VSTS.
I am using JDBC Connection Configuration step to create a connection with SQL server database.
Error
2019-12-12 11:58:14,882 WARN o.a.j.p.j.p.AbstractJDBCProcessor: SQL Problem in JDBC PostProcessor: java.sql.SQLException: Cannot load JDBC driver class 'com.microsoft.sqlserver.jdbc.SQLServerDriver'
What you can do is to just simply include the required jar files(in this case jdbc driver jar) along with the other supported files(e.g any csv file for data).
This message usually means that the jar file for class com.microsoft.sqlserver.jdbc.SQLServerDriver was not found in VSTS classpath.
Have a look at this thread which sheds some light on how to achieve this:

I recently updated to jmeter 4.0 from jmeter 3.2. In jmx file, i have query to execute and it was running fine in jmeter 3.2 . But the jmx file fails with error "Response message: java.sql.SQLException: Cannot load JDBC driver class 'com.microsoft.sqlserver.jdbc.SQLServerDriver'" in jmeter 4.0. Please help me in resolving this issue.
below is the screenshot of JDBC Connection Configuration
You need to
Download Microsoft JDBC Driver for SQL Server
Extract mssql-jdbc-x.x.x.jrex.jar somewhere to JMeter Classpath
Restart JMeter to pick the .jar up

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
No suitable driver found for jdbc:oracle for JDBC request in JMeter.
Configuration details:
Suggest if any changes required to resolve it.
Make sure your add Oracle JDBC driver to JMeter Classpath and restart JMeter afterwars.
I am not sure that copying and pasting tnsnames.ora into the JDBC URL is supported, as far as I'm aware you need to set oracle.net.tns_admin system property and use TNS entry in the JDBC URL like jdbc:oracle:thin:#your_entry_name_here
I also believe you should change your "Validation query" to SELECT 1 FROM DUAL
