Sister blog - GlassFish for Business

While this Aquarium blog is a one-stop-shop for anything GlassFish and Java EE from Oracle and from the community, we also maintain a GlassFish for Business blog for those of you interested in making the most of your GlassFish commercial license.

GlassFish For Business Blog

The most recent post there, "Difference between GlassFish Open Source and Commercial Editions", covers just that - why even acquire an Oracle GlassFish Server license? Is is just the support or is there anything more? (hint: there's more).

Another recent post covers the release of Oracle GlassFish Server 3.1.1 Patch 2, a great example of the value for GlassFish customers - a regular cadence of patch releases.

For those interested in finding out more :
Tech Price List (grep for "GlassFish")
Commercial GlassFish Offerings from Oracle (how fixes are applied to commercial an open source bits)
Oracle GlassFish Server and GlassFish Server Open Source Edition (Free vs. commercial, a blog from last year). Being consistent is a good thing (tm).

Buy Oracle GlassFish Server, what do you get?

What is the difference between GlassFish Open Source Edition (OSE) and Oracle GlassFish Server (OGS)?

ALT_DESCR

The short answer (GlassFish Server Control) was previously given here.

But wait, there's more! The longer answer is detailed in this licensing document listing Oracle GlassFish Message Queue, Oracle GlassFish Server HTTP load balancer plug-in, GlassFish Server Control, Oracle TopLink but also Oracle JRockit JDK and Hotspot JDK.

Oracle GlassFish Server is licensed per processor and the document listed above includes similar licensing information for Oracle Coherence, Weblogic, TopLink and more.

Remember that you can also upgrade an Open Source Edition installation to the Oracle GlassFish Server product by using the Update Center feature of the product.

GlassFish 3.1 SOTD #6 - Monitoring Scripting Client

In this sixth post of the SOTD (Screencast Of The Day) series following the release of GlassFish 3.1, here is Tom's Monitoring Scripting Client.

This is a feature that is part of Oracle GlassFish Server Control which comes bundled with Oracle GlassFish Server and available for free trial.

This 8-minute demo shows how this scripted monitoring command (asadmin run-script) can operate on a 2-instance cluster (setup included in the demo) using one of the 100+ fine grained probes defined in JavaScript. This is a supported version of the technology previously made available in beta form and which now obviously has been extended to clustered environments.

This screencast is hosted on the GlassFish YouTube Channel.
