CVS Dataset Config Usage?
Hi, i am experimenting with the csv dataset config but it seems like i do not quite understand its inner workings. What i am trying to achieve is the following: - keep a file of usernames, passwords and other config for users around which is always 100 lines long. - for testing a new jmeter script i would like use different settings for threads and repeat (eg. 2 threads, 10 repeats) I thought that jmeter reads the cvs file at the beginning of the testcase, assigns values to the different threads (=users) and thats it. But that does not work. With 1 thread and 10 repeats the second repeat of the test gets the config for user 2 (=line 2 of csv file). So it seems like the file is read in every iteration. How is the csv config thought to be used? Do i have to exactly match the lines in the file to the number of threads i want to use? What if one of the threads gets an error and is stopped? Will not the correlation between thread csv config will be mixed up? Kind regards, peter - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
JMeter problems when connecting to a MySQL database
I am attempting to test out a MySQL database using Apache Jmeter. When I do so, Jmeter logs the following error message to a file: java.sql.SQLException: No suitable driver I've googled around, but I don't have a lot of Java knowledge and I'm finding it difficult to determine what the classpath is, let alone how to set it or even where to grab this driver file that it's looking for (which is com.mysql.jdbc.Driver, I'm assuming). The same error message also occurs on a Windows XP VM that I used for testing, so I know it's not an OS X specific problem, but that's the one that I'll be running it from. Any assistance would be greatly appreciated! -- View this message in context: http://www.nabble.com/JMeter-problems-when-connecting-to-a-MySQL-database-tf4116479.html#a11706383 Sent from the JMeter - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: JMeter problems when connecting to a MySQL database
Hello Piotr, thank you for responding so quickly. I have downloaded the JDBC drive for MySQL, but I am not sure if I have installed it correctly. I have copied the mysql-connector-java-5.0.6-bin.jar file to the /lib/ext directory, but I now see the following error message repeated in the output file: com.mysql.jdbc.CommunicationsException: Communications link failure due to underlying exception: What have I done wrong?

RE: Can't adjust characters per second
Hi Sebb- Is there a library that I need to load to get access to the httpclient.socket.http.cps related methods? If so, how would I do that? If not, then why do I get a null pointer exception every time I enable this feature with Jmeter 2.2 and 2.3? Is the bandwidth constraint applied on a per thread basis, or across all the threads cumulatively? Thanks, Alan -Original Message- From: Christensen, Alan Sent: Wednesday, July 18, 2007 11:48 AM To: JMeter Users List Subject: Can't adjust characters per second I tried using the characters/second setting in the jmeter.properties file. My recollection is that this only works with the commons HTTP client. Is that correct? When I set cps to 1 cps using the following statements in jmeter.properties httpclient.socket.http.cps=1 httpclient.socket.https.cps=1 then I get a null pointer exception for every http request that I make using the HTTP Request HTTPClient sampler. From jmeter.log: ERROR - jmeter.threads.JMeterThread: java.lang.NullPointerException at org.apache.commons.httpclient.HttpConnection.open(HttpConnection.java:72 0) at org.apache.commons.httpclient.HttpMethodDirector.executeWithRetry(HttpMe thodDirector.java:386) at org.apache.commons.httpclient.HttpMethodDirector.executeMethod(HttpMetho dDirector.java:170) at org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:3 96) at org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:3 24) at org.apache.jmeter.protocol.http.sampler.HTTPSampler2.sample(HTTPSampler2 .java:527) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.sample(HTTPSampl erBase.java:658) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.sample(HTTPSampl erBase.java:647) at org.apache.jmeter.threads.JMeterThread.run(JMeterThread.java:247) at java.lang.Thread.run(Unknown Source) The HTTP Request HTTPClient works fine when the lines above are commented out. I am running jmeter 2.1. Is this bug fixed in 2.3? I also have a question about when jmeter reads the jmeter.properties file. I am assuming that jmeter only reads this file when it is first started. Is this correct? Thanks, Alan - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: JMeter problems when connecting to a MySQL database
OK. I modified the 'my.cnf' file, restarted the mysql daemon and made sure that it was listening on the local address. The port now shows as being open when I scan the machine. Jmeter still seems to have trouble connecting as it's still hanging after the test is started and logging nothing to the output file other than the column headers.
