Cannot load JDBC driver class 'com.microsoft.sqlserver.jdbc.SQLServerDriver' error display while running JMeter load test in VSTS - jdbc

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:

Jmeter and Oracle Connections - JDBC Request

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JDBC driver might be outdated.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

Tibco Service JDBC SQL deployment issue

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

How to resolve error "Cannot load JDBC driver class" displayed in jmeter 4.0

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
See Building a Database Test Plan and How to use Different JDBC Drivers articles for more details on how to use JMeter for database testing.

Weblogic 12.2.1.3.0 Developer - Unable to create data source using admin console

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:
Caused By: weblogic.common.ResourceException: weblogic.common.ResourceException: Could not create pool connection. The DBMS driver exception was: null

i suggest reverting any network changes that might have taken place.

BIRT Report not connected with sql server jdbc 4.0

When I deployed sample test report in apache tomcat 7.0.67, it was running correctly and another report connected with SQL server 2012. Report design preview is also working. BIRT report design manage driver, jdbc driver have been added and test connection found ok.
sqljdbc4.0.jar has been added to the Apache tomact BIRT\WEBINF\lib
but local host showing following error:
org.eclipse.birt.report.engine.api.EngineException: An exception occurred during processing. Please see the following message for details:
Cannot open the connection for the driver: org.eclipse.birt.report.data.oda.jdbc. Java Runtime Environment (JRE) version 1.8 is not supported by this driver.
Use the sqljdbc4.jar class library, which provides support for JDBC 4.0.
