I have a problem connecting to Oracle from JMeter. I received this error:
Response code: null 17002
Response message: java.sql.SQLException: Io exception: The Network Adapter could not establish the connection"
I have ojdb14, 6, 5 and more in /lib
added class12 in /lib and /lib/ext
Then in test plan, I added jars to classpath, all pointing to jar lib.
Any suggestions? Thanks.
could it be in how to write the JDBC:
Make sure you have Oracle JDBC driver somewhere in JMeter Classpath
Make sure you have configured network adapter in the virtual machine in Bridge mode (not "host-only", not "NAT") so the virtual machine would have its own IP address.
Make sure port 1521 (or whatever is used by Oracle) is not blocked by OS firewall. Check if you are able to connect to the port using i.e. telnet client
Add JDBC Connection Configuration test element and provide JDBC url of your Oracle instance along with credentials there.

I have to connect my JMeter script to AWS RDS database.
When I am running my test with the below JDBC Connection configuration it is showing this error message:
java.sql.SQLException: Cannot create PoolableConnectionFactory (Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.)
JDBC Connection configuration:
JDBC Request:
Response Error Message:
I already added mysql-connector-java-8.0.25.jar file in Jmeter's /lib folder, but it didn't help.
From JMeter perspective your connection configuration looks OK, the problem is on RDS end. The only thing you can do from JMeter is try increasing JMeter logging verbosity for the MySQL Connector/J in order to get more troubleshooting information in jmeter.log file, the line to be added to JMeter's log4j2.xml file is:
<Logger name="com.mysql.jdbc" level="debug" />
Troubleshooting steps for RDS/AWS/MySQL:
Make sure to open port 3306 in the RDS Security Groups
Make sure to whitelist the external IP address of your JMeter machine(s) in the VPC Security Group (or use wildcard like 0.0.0.0/0 so anyone will be able to connect)
Make sure that your MySQL instance is bound to the public IP address or listening on all interfaces, see bind-address directive
While running an SQl query in JMeter using JDBC request, I'm getting:
SQL ConnectionException:Cannot create Poolable Connectionfactory
(IO error:Network Adapter could not establish the connection).
Installed Oracle11g in virtual machine.
Please give me solution.
Thanks in Advance.

i have tried to connect from Jmeter to external mysql server using JDBC sampler. But I am getting erros. its possible to connect to the local mysql server.I am confused how to connect jmeter from my local machine to server database in other machine using JDBC CONNECTION
Make sure you remote MySQL server is accepting remote connections. Locate bind-address line in my.cnf file and set it to listen on all interfaces:
bind-address = 0.0.0.0
See Troubleshooting Problems Connecting to MySQL for more details. You will need restart MySQL server in order to pick up any changes made in my.cnf file
Make sure your operating system firewall on MySQL server side allows incoming connections to MySQL server TCP port (default is 3306).
Verify that you able to hit port 3306 with a telnet client or equivalent
If you will be still experiencing problems - update your question with JDBC Request sampler output and jmeter.log file contents. I would also recommend checking out The Real Secret to Building a Database Test Plan With JMeter to learn more about the concept of databases load testing using JMeter
If you are able to connect to that server using MySQL Workbench or another tool just use the below config for JMeter.
Just remember that you need to have mysql-connector-java-5.1.40-bin.jar (or another version of it) under apache-jmeter-3.0\lib\ folder.
Hope this helps!
I am using TeamCity version 10.4. I am trying to create the database on my local machine.
However, I am getting this error:
The connection to the host localhost, named instance hsalman-pc failed. Error: "java.net.SocketTimeoutException: Receive timed out".
Verify the server and instance names and check that no firewall is blocking UDP traffic to port 1434. For SQL Server 2005 or later,
verify that the SQL Server Browser Service is running on the host.
I have the required driver here:
Aslo, I cannot locate the database properties file in the data directory. So what is the problem?
Is there a way that I can configure a XE installation on Windows to only use ports on the localhost interface and not the external interfaces? I'd like to run it for development without having anyone else be able to connect to my instance.
I tried modifying the listener.ora and tnsnames.ora file, changing the 'HOST =' entries to localhost. My hosts file has the following line in it:
127.0.0.1 localhost
When I've done this, and restarted the services, apex stops working (it doesn't listen on port 8080) and I'm unable to connect to the database using JDBC. I get the following error with JDBC:
Exception in thread "main" java.sql.SQLException: Listener refused the connection
with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect
descriptor
The Connection descriptor used by the client was:
localhost:1521:XE
I should note that both apex and JDBC work fine if I change the 'HOST = entries back to my machines hostname and restart the services.
There are two parts for this (because there are two 'technologies' serving different ports).
Firstly the listener for database port 1521. You use a SQLNET.ORA setting (tcp.invited_nodes) as a soft firewall, so the listener will ignore other nodes.
Secondly, for the 8080 PL/SQL gateway you need to use DBMS_XDB.SETLISTENERLOCALACCESS as described here
