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'

Little help I could find on internet so I am asking for help.
Perhaps my Internet is better than yours because I can find a little bit more "help".
In the Configure the Databricks ODBC and JDBC drivers documentation chapter I can see JDBC Driver Guide section which looks like:
For more information about the JDBC driver, refer to the installation and configuration guide. Find the Databricks JDBC driver installation and configuration guide in the docs directory of the driver package.
In the docs directory of the downloaded JDBC Driver there is Databricks JDBC Driver Install and Configuration Guide.pdf file.
In the Registering the Connector Class chapter of this file it suggests to use com.databricks.client.jdbc.Driver as the classname

Looking into Hive JDBC driver source:
Utils.verifySuccess(openResp.getStatus());
if (!supportedProtocols.contains(openResp.getServerProtocolVersion())) {
throw new TException("Unsupported Hive2 protocol");
}
it seems that your JDBC driver version doesn't match the server-side version, you need to download exactly the same version of the JDBC driver which matches your server installation.
If you cannot figure out the correct version of server you can enable debug logging for Hive JDBC driver and inspect jmeter.log file for any clues.
In the meantime you can try use hive instead of hive2 in the JDBC URL, however it might have negative impact to the results as they won't be that realistic
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.

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 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

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
