Sharing the JDBC Connection between all the threads

All the threads can share a single CSV input but for them to share a single JDBC Connection I'm yet to find how. It'll help to send unique values in the requests from all the threads. thanks
Re: Help Needed in creation of JDBC connection at runtime
You could create a pre-flight Jmeter Test plan that will generate a property file with those values and use it as data on your JMeter script with the simulated scenario. This is only one way to do it, and I'm pretty sure that there are plenty more. JMeter has other components to help you achieve this goal. Best of luck. Be safe and drink water!

Help Needed in creation of JDBC connection at runtime
Hi, Is there anyway where we can create a JDBC connection using JDBC Connection Confiuration during runtime. The user name and password will be generated with a temporary connetion and new username and password will be used to create a new connection during runtime. Thanks Deepak
Re: Does JDBC Connection Config component respect its scope?
There's a general note about configuration elements ( http://jmeter.apache.org/usermanual/component_reference.html#config_elements ) elements are processed at the start of the scope in which they are found, i.e. before any samplers in the same scope. There's such note in CSV Data Set Config ( http://jmeter.apache.org/usermanual/component_reference.html#CSV_Data_Set_Config ) CSV Dataset variables are defined at the start of each test iteration. As this is after configuration processing is completed, they cannot be used for some configuration items - such as JDBC Config On Mon, Nov 27, 2017 at 12:58 PM, Konstantin Kalinin < konstan...@kkalinin.pro> wrote: > Hello! > > I'm using JMeter 3.3. > I try to setup a JDBC Connection Config (JDBC CC) this way: > > Test plan > |__setUp Thread Group > |__Sampler1 (sets variables) > |__JDBC Request1 > |__JDBC CC (using vars from Sampler1) > > Seems that JDBC CC initializes when Test plan is loaded, no matter where > it is in the plan, as it can not use variables that I've set in Sampler1. > Adding some tree levels with different Controllers changes nothing. > It behaves like a User Defined Variables config element do, but there's no > note about it in a Documentation.

Does JDBC Connection Config component respect its scope?
Hello! I'm using JMeter 3.3. I try to setup a JDBC Connection Config (JDBC CC) this way: Test plan |__setUp Thread Group |__Sampler1 (sets variables) |__JDBC Request1 |__JDBC CC (using vars from Sampler1) Seems that JDBC CC initializes when Test plan is loaded, no matter where it is in the plan, as it can not use variables that I've set in Sampler1. Adding some tree levels with different Controllers changes nothing. It behaves like a User Defined Variables config element do, but there's no note about it in a Documentation. I expect, that JDBC CC would respect it's scope. Is it a bug? -- Konstantin Kalinin +7 912 468 00 00 - To unsubscribe, e-mail: user-unsubscr...@jmeter.apache.org For additional commands, e-mail: user-h...@jmeter.apache.org

With warm regards., Vijayakumar.C Hi C.Vijayakumar, Let me say, what I think about JMeter's problem with memory. 1.Do not use any Graph Listeners, they are too greedy and can waste your RAM There is some observation of this problem in article about JMeter Listeners(http://blazemeter.com/blog/greedy-listeners-memory-leeches- performance-testing) 2.If possible, do not use JMeter GUI at all, because it may be too heavy for your PC. Some advices you can find in articles, devoted to Running JMeter tests in non-GUI mode(http://blazemeter.com/blog/dear-abby-blazemeter-how-do-i-run- jmeter-non-gui-mode) and collecting load test results(http://blazemeter.com/blog/top-2-techniques-get-jmeter-test-results-non- gui-mode) - To unsubscribe, e-mail: user-unsubscr...@jmeter.apache.org For additional commands, e-mail: user-h...@jmeter.apache.org -- Namaskara~Nalama~Guten Tag~Bonjour -- Keigu Deepak +91-9765089593 deic...@gmail.com http://www.simtree.net Skype: thumsupdeicool Google talk: deicool Blog: http://loveandfearless.wordpress.com Facebook: http://www.facebook.com/deicool Contribute to the world, environment and more : http://www.gridrepublic.org - To unsubscribe, e-mail: user-unsubscr...@jmeter.apache.org For additional commands, e-mail: user-h...@jmeter.apache.org

More details then. What is the exact configuration of the JDBC sampler? What errors are generated when you do it this way? - To unsubscribe, e-mail: user-unsubscr...@jmeter.apache.org For additional commands, e-mail: user-h...@jmeter.apache.org
