Hi,
There is no publicly available release date for the next version of JRockit at this time.

Hi,

Our next release, JRockit R27.6.2, will be available on METALINK (for customers with support contract) by the end of this month.

Did this update go out the door yet? I'm new with metalink, so I want to make sure I'm not just looking in the wrong place.

Thanks.

I am sorry but it seems as I was a bit optimistic. R27.6.2 is being integrated in WLS Farallon and will not be GA until Farallon goes live (which is not yet settled). However, you are able to download R27.6 from http://www.oracle.com/technology/software/products/jrockit/index.html.

What is the reason for upgrade? Is it something specific you are waiting for?

Best Regards
Tuva

Performace enhancements are always welcome (grin). But no, I was just starting on some performance testing and I didn't want to redo everything if a new version was out or nearly out. I've got the 27.6.0, thanks.

R27.6.1 and R27.6.2 are maintenance releases - patches only and no features or performance enhancements. That's what bumping the last number in the version string means. So no new goodies there, I'm afraid. On the up side - you can do your performance testing with R27.6.0 and upgrade to R27.6.2 without rerunning those performance tests.

Our version numbering scheme is described in our docs.

Regards,

Henrik

Do you have a list of feature requests for Mission Control? I'd like to add these to the list:

*1) Allow resizing of the 'thread name' column on the latency tab:*

*2) Show the thread details in the left pane and/or additional info onscreen if possible (without hover)*

*3) Show the 'GCs' tab even if there are not any garbage collects (so the heap usage graph can be viewed)*

Hi,

I think there are big problems with the Jrockit development team in Oracle. Until Jrockit was a Bea product, there will be regular quarterly releases, with tons of new features, ideas,enhancements.

Oracle will producing only some bugfixes after 1 year of the last release, it means that the brilliant brains who created Jrockit are not in their development team (or they administratively blocked them).

The biggest problem is that a sw. product can be enhanced by hundreds of ways. If Oracle was unable to improve the product after 1 year it means that they did not think Jrockit is a strategic product for Oracle (or big dark politics in it)

Summarize I think the Jrockit future is very dark, it is not the same bright product that it was 1 year before;
I hope it will be open the way for new JVM variants with new ideas

- the same story about the big companies and bright products..

I guess I've had a different experience. Nothing is faster than JRockit for our WebLogic 8.1.6 application and I haven't found any tool which gives me the kind of information I get out of a JRA recording and Mission Control. I've also had great support through the forums and help tickets. These are simple 'wish list' type requests for a product we are already happy with.

That's a very bleak picture of JRockit's future and would be depressing if true. Which it luckily is not.

If you were at Oracle OpenWorld last year, or had attended Oracle webcasts etc after the BEA acquisition then you must have heard that Oracle is standardizing on WLS and JRockit across its entire middleware and applications portfolio. That has been keeping us busy for a while - lots of new internal customers to support, feature requests to fulfill etc. Some of the stuff we were working on have been put on backburner for a while but nothing - nothing! - has been cancelled. We are now reaching the end of this tunnel and will emerge having a large number of new products running on JRockit, a larger engineering team, support from the entire Oracle organisation etc. We have just finished a performance project bumping JRockit up on certain workloads by up to 15-20% (release in May) and we have some very interesting stuff we're working on that will be revealed in due time. All good things come to those who wait :-)


Cheers,

Thanks for you feature requests.

<i>1) Allow resizing of the 'thread name' column on the latency tab:</i>
It's already on our list of future enhancements :)

<i>2) Show the thread details in the left pane and/or additional info onscreen if possible (without hover)</i>
That's a great idea! We should have threads information visible in the properties view.

<i>3) Show the 'GCs' tab even if there are not any garbage collects (so the heap usage graph can be viewed)</i>
Today JRockit only writes down heap usage after a garbage collection so it wouldn't be much to see. You can however see all the tabs, even if the recording doesn't contain information for that particular tab, if you go to Windows->Preferences->RunTime Analyaer(JRA) -> Show every tab..

If you have more feature requests you can send an email to jrockit-improve at oracle or just post them here like you did.

Thanks again!

Erik
