Hello Hyunsik,
thanks for your reply.
With your hint you were right. My mistake. I had assumed that these three files
are the minimum requirement.
Today I spent the whole day with performance test, relationship as trying to
make this run.
So far I have not found a way to in the configurations. Is there a
configuration setting with which you can control the number of parallel
connections?
Until now I get the following exception namely:
2014/08/13 19:03:04 WARN - jmeter.protocol.jdbc.config.DataSourceElement:
Could not return Connection java.lang.Exception: Could not create enough
Components to service your request (Timed out).

I can jMeter running against a Postgres database successfully, only the Tajos
remains a problem.
!!!Thank you so much for the past really helpful tips and advice.!!!
Best regards,
Chris
