Solaris CPU run query report


Here I would like to provide small awk bases script to collect information about CPU run query statistic report on Sun Solaris OS.

 

In most Sun Solaris OS (9,10) after installation and put production mode you can detect too much processes are on sleep mode then in run mode. It often generate System Low Performance when Running non-stop online processes like with Database Instances or Java Based Application Servers.

Solaris 10 wanboot installation or Solaris 10 installation over web / HTTP


In this articles I will provide the Solaris 10 Installation mode over HTTP named as WanBoot method for SPARC Systems.

Here I will provide only HTTP installation way.

Another possible situation where you can use this method can be when new fresh system located on customer site with Internet access and you just have remote access to this system into ALOM over VPN or direct access though Internet. Therefore you can use your already prepared Installation WanBoot server for this systems.
