Testing Java 6 7 8

Postby Michael.Scaman » Mon Feb 02, 2015 3:41 pm

I need to evaluate test of Java 1.6 but the EA says you need Java 8. Is there an older version of the EA I can try...

and a related question is how do people who need to evaluate multiple Java platforms use your tool or even flip between different JVM's for 6 7 8

thanks... just trying to get started with the EA and learning here. Any suggestions appreciated

You must have misinterpreted the message.

Java 8 is required to run the profiler UI itself, but you still can profile Java applications running on Java 6 and newer.

and a related question is how do people who need to evaluate multiple Java platforms use your tool or even flip between different JVM's for 6 7 8

Please see above.

What is your platform by the way? Please note that Windows and Linux bundles already have appropriate JRE on board, so will run out of the box. On other platforms you simply need to install Java 8 in parallel to existing JVMs.

OK, so just the UI requires Java 8

Mac OS x Yosemite on laptop, Linus on server
I can also switch to Windows on it... but that's less ideal since the target product is linux
I would like to test things on my laptop on Max OS x and also on Linux running on Linux boxes remotedly

thanks

Mac OS x Yosemite on laptop,

If you plan to run the profiler UI you need to install Java 8 (recommended) or Java 7 (not recommended) in parallel to, I suppose, the existing Apple Java 6.

Linus on server

If you don't need the profiler UI, there is nothing to care about. Otherwise simply use the Linux bundle with the JRE included.

I can also switch to Windows on it

As I wrote, the Windows installer contains the JRE to run the profiler so no extra steps are needed.

OK...
so the UI is an issue but I am mostly concerned with non UI, linux application so it doesn't sound mostly like an issue

What't the best things to look at to get oriented in using YourKit for a non UI on a remote linux box
(used from Mac OS X )

and sorry to belabor the issue....

If I use the Windows version can I remotely profile Java on the server

Hi Michael

Remote profiling is the best approach.

First, please enable profiling on the remote Linux machine:
https://www.yourkit.com/docs/java/help/ ... remote.jsp

When the application or the EE server you want to profile is up and running, run the profiler locally and connect to the remote application:

https://www.yourkit.com/docs/java/help/ ... filing.jsp

Best regards,
Anton
