The documentation for Solaris 10 Update 4, called Solaris 10 8/07 release, is now on docs.sun.com. The downloadable ISOs for U4 are still missing on sun.com. Hope to have them soon.

Hope to see some information from Sun about the release date of Solaris 10 Update 4, soon. As I can see, a lot of people are googling for this, about 688 visits only on this blog within the last week.
The first Sun Blade 6000 with a couple of Sun Blade X6250 Server Modules with Intel Clovertown Quad Core CPUs and 32Gb RAM arrived. The chassis is really heavy, we’ ll put it in the Colocation Rack within the next days with three people…
The Chassis and one X6250 Server Module:
Solaris 10 Update 4, called Solaris 10 8/07 now, is late! We already expected U4 as Solaris 10 7/07 this month. As mentioned in opensolaris forums, release date for Solaris 10 U4 is 08/07/07, now.
Solaris Express Developer Edition 5/07 is available now, and there are a lot of new features and packages within this distribution.
A couple of the interesting ones:
- Glassfish Application Server (have to check the version)
- Sun Studio 12
- PostgreSQL 8.2.4
- Apache 2.2.3 (have to check if mod_ldap is already compiled…)
- and many more…
Full detailed what’s new pdf.
Hope to have these packages with Solaris 10 for production, soon. With Solaris 10, we’ re still on apache 2.0.x..
Tomcat and mysql bundled with Solaris 10 are also quite a bit too old for web2.0 projects, which we have in production today.
Currenty, I don’t findy any VMware images to download, only the usual setup DVD download.
not too small, these Sun Fire X4600 M2 Servers with up to eight Quad Core AMD Barcelona Opterons.
Morgen und nächste Woche findet Ihr mich hier.
To run an J2EE application server like glassfish in production brings a lot of additional work after installation. While a simple installation for developers is easy, it seems no so easy today to bring glassfish in production. From my point of view, there are at least the following things to do for a production installation:
- Add new user and group (e.g. glassfish) to /etc/passwd /and /etc/group
- install latest jdk
- install glassfish
- setup and install start/stop scripts (smf on Solaris10)
- install glassfish apache 2.2 ajp integration (example1 example2 example3)
- configure glassfish logfile rotation
- tune glassfish because default settings are not suitable for production ( a lot of parameters!)
- harden glassfish because default security settings are not strong and secure enough
- deploy jdbc configuration (jars + settings)
- write scripts to integrate glassfish in your monitoring framework
- write scripts to integrate glassfish in your deployment framework (e.g. Sun N1 SPS)
- and of of course, this list is not complete
Nowadays, we have at least three (virtual) servers for each customer project. One for development, one for test and ond for production. This means to install and modify glassfish at least three times. But often, we also have hardware based load balancing in projects, that means to have at least two strings of glassfish for dev/test/prod or six installations alltogether!
Looking at the new glassfish V2 feature called application server usage profiles shows, that the three offered profiles (“developer”, “cluster”, “enterprise”) still leaking real production settings. A simple “production” or production-cluster profile would be nice. The production profiles should have tuned values (at least the parameters mentioned in the Sun Java System Application Server 9.1 PerformanceTuning Guide beginning on page 50) which makes it easier to setup glassfish for admins. The mentioned enterprise profile might be not the best for high traffic web 2.0 production web sites.
How do we do this job with other app servers? For a couple of customers, we’re using the Bea Weblogic Application Server. And we’re using the Sun N1 SPS Bea Weblogic module to install and configure Weblogic. N1 SPS also uses the possibility to run the WebLogic Scripting Tool (WLST) , which is a BEA tool for scripting the configuration of BEA WebLogic. WLST is a command-line scripting interface to monitor and manage BEA WebLogic Server instances and domains. The WLST scripting environment is based on the Java scripting interpreter, Jython.
Someting like this (GFST) would be cool to have for glassfish, too.
Regarding the article on golem, Sun Studio 12, based on NetBeans 5.5.1, will be available in June 2007.
