I installed Solaris 10 05/09 on a machine and I used whatever the default swap space setting when I built the box. Now I need to increase the swap space and I can’t add a swap file, like was possible under UFS. If your swap device is in use, then you might not be able to delete it. Check to see if the swap area is in use. For example: ...

Optimized Applications for Solaris OS and OpenSparc computing. Simple and very useful example is “Cool Stack” a web deployment packge include most commonly used free and open source applications, recompiled to deliver a 30 to 200 percent performance improvement over standard binaries compiled with GCC. Cool Tools.

Uso Solaris da quasi un anno ma non mi sono mai cimentato nell’uso delle famose Zones riassumendo i poche parole giusto per capire di cosa si parla dico: “operating system level virtualization” bash-3.00# zonecfg -z Z01 Z01: No such zone configured Use 'create' to begin configuring a new zone. zonecfg:Z01create -b zonecfg:Z01set zonepath=/zones/Z01 zonecfg:Z01exit bash-3.00# zoneadm -z Z01 install Preparing to install zone <Z01>. Creating list of files to copy from the global zone. Copying <115072files to the zone. Initializing zone product registry. Determining zone package initialization order. Preparing to initialize <792packages on the zone. Initialized <792packages on zone. Zone <Z01is initialized. The file </zones/Z01/root/var/sadm/system/logs/install\_logcontains a log of the zone installation. bash-3.00# bash-3.00# zonecfg -z Z01 zonecfg:Z01add net zonecfg:Z01set address=10.0.0.1 zonecfg:Z01set physical=hme0 zonecfg:Z01end zonecfg:Z01verify zonecfg:Z01commit zonecfg:Z01exit > bash-3.00# zoneadm -z Z01 boot > bash-3.00# zlogin -C Z01

Oggi durante una serie di comandi con un senso ben preciso Solaris mi ha parlato in questo modo: Sorry, I don't know anything about your "xterm-color" terminal. La perplessità generale mi ha fatto lanciare questo comando: bash-3.00# export TERM=vt100 Ma molto probabilmente sarebbe stato meglio un terminale “ansi”

Un piccolo memo sul sistema di gestione delle patch in Solaris, patch ID 121118(SPARC version) o 121119(x86 version) Questi sono i comandi principali: Analyze: /usr/sadm/bin/smpatch analyze Download: /usr/sadm/bin/smpatch download Add Patch: /usr/sadm/bin/smpatch add Bisogna registrare il sistema con questo comando: # /usr/sbin/sconadm register -a -r /tmp/registrationprofile.properties Il file /tmp/registrationprofile.properties deve essere una cosa simile a questo: userName=newuser password=newpassword hostName= subscriptionKey= portalEnabled=false proxyHostName= proxyPort= proxyUserName= proxyPassword=

Da qualche mese a questa parte ho avuto la pazza idea di usare solaris, credo che non ci sia migliore cosa che provarlo in produzione, quindi ho spolverato una Ultra 10 presa tempo fa e mai seriamente utilizzata, tolto la SunPCI e installato Solaris 10.
