If you are not familiar with WebLogic Server multi-tenancy support, you should read Tim Quinn's blog: Domain Partitions for Multi-tenancy in WebLogic Server.  It gives a nice overview of the partition feature in WLS 12.2.1 and covers concepts that are used in this article. Partition Targeting As you learned in Tim's blog, a domain partition (partition for short) is an administrative and runtime slice of a WebLogic domain that contains a collection of application and resources....

After installing GlassFish and running either the bin/pkg or bin/updatetool commands for the first time you may see a message like this: The software needed for this command (updatetool) is not installed. and you will be asked if you would like to install the software or not. GlassFish distributions do not always contain the full Update Center Toolkit, instead it is downloaded on demand. If you answer "yes" then the software needed to support the command (pkg or updatetool)...

I needed to build a project on my MacBook that required GNU msgfmt. I could have built it from source, but instead I decided to install MacPorts in case I needed other open source type packages in the future. Installing MacPorts is fairly straightforward, but the first thing you must do after installing the base image is synchronize with the MacPorts repository by running: $ sudo port -d sync That failed for me because MacPorts uses rsync to access its repositories, and I was...

Secure by default is the characteristic of software where its default installation results in a secure configuration. Often there is a trade off between ease of use and the degree of default security. In GlassFish 3.1.2 we have improved the secure by default behavior, and we've tried to do so without impacting the ease of use that GlassFish is known for (at least not impacting it too much). We had two main goals we were trying to satisfy in 3.1.2: More actively encourage the...

GlassFish 3.1 has the ability to use SSH to centrally administer some basic instance lifecycle operations (such as creating and starting an instance). But in some cases you may not want to deal with SSH, and would rather just create and start those instances directly yourself. GlassFish 3.1 supports that too. This blog describes how to set up a two instance cluster across three machines without using SSH. As part of this procedure you will be enabling secure admin on the...

GlassFish 3.1 introduces the use of SSH to manage the lifecycle of remote instances. This document gives an overview of how to use SSH with GlassFish and describes some alternatives if SSH is not practical in your environment. 1) SSH use in GlassFish 3.1 The Domain Admin Server (DAS) for GlassFish must be able to communicate with remote instances to perform various administrative operations. For most operations this communication occurs directly between the DAS and the running...

During the final testing of GlassFish Enterprise Server v3 the GlassFish QA team reported this Update Center bug: 11185 Installer hangs at 41% intermittently We knew that at this phase of the install the update center was bootstrapping (downloading and installing) itself from the network repository into the installation image.  After some initial analysis we determined a few more things: this was only on Windows Vista and Windows 7, it has a hard hang, it was intermittent,...

wxWidgets has been integrated into OpenSolaris. Here are a couple tips for building against these libraries that worked for me (I am running on OpenSolaris 2008.11). Install the wxWidgets package: $ pfexec pkg install SUNWwxwidgets $ wx-config --version 2.8.8 Install the Sun Studio Compiler: $ pfexec pkg install sunstudioexpress@0.2008.11 Note that the 2009.3 version of the compiler is also available in the repository, but I had better luck with the...

I recently produced a screencast for Update Center 2, and I've had some folks ask me how I did it. There are a zillion tools and techniques for producing screencasts. This blog describes one approach. I in no way claim it's the best approach -- and in fact I'm certain it is not. But it worked OK for me. I did this on a Mac laptop running Mac OS 10.5. Windows users will likely need to look elsewhere for guidance.I've broken down the job of creating a screencast into...
