Solaris 11 Changes: Where is the BSD style ps command?

Short Answer: In /usr/bin/ps


Oracle's new operating system Solaris 11 (Express) is a modular operating system based on the IPS installation technology. This feature has been used by Oracle to make the BSD commands in the directory /usr/ucb an optional package which doesn't get installed by default (see previous post). The BSD commands shouldn't be used since they're a backwards compatibility courtesy allowing 20th century applications written for SunOS 4 to operate without changes.

Solaris 11 Changes: Where is /usr/ucb ?

Solaris 11 Express as a predecessor to Solaris 11 ist out and a few things changed and improved...

The directory /usr/ucb isn't there anymore ...

The usage of the BSD commands in /usr/ucb has always been discouraged. The BSD commands have been provided as a backwards compatibility option for SunOS 4.1. People used them in Solaris 2 since they had interesting features. It has never been a good idea to rely on them in Solaris 2

Drupal 7 has been released

Make your Application work on Solaris 11

Oracle just published a white paper about making applications work on Solaris 11. Most applications working on Solaris 10 will work without any modification on Solaris 11. The most senior engineers from ISV-Engineering came together and compiled this document with the very few corner cases where an application may see hick ups. All known cases deal with general innovation like upgraded frameworks or retired very old frameworks.

Workaround; Apple Java Update(1.6.0_22-b04-307) breaks OpenOffice 3.2.1

 The Apple Java Update 3 from Oct. 20, 2010 breaks OpenOffice 3.2.1. OpenOffice can't find the Java JRE anymore. OpenOffice becomes fairly crippled and it shows lots of popups depending on what you do.

The workaround for this problem is described in the OpenOffice bug report 115180.

 Great move to stay in touch with OpenJDK!

Virtualbox 3.2.8 ready for download

New month, new VB update. Same quality as always. The change log refers to a regression, fixed memory leaks, USB enhancements, Windows and RHEL fixes.

The upgrade worked on my Mac worked like a charme. My frozen images survived the upgrade without a reboot.

Good job Oracle engineers, thank you!
