15. The S in SAMP stands for Solaris MySQL /var/svc/manifest/network/mysql.xml /lib/svc/method/CSKmysql # svccfg import /var/svc/manifest/network/mysql.xml # svcadm -v enable mysql Apache /var/svc/manifest/network/http-CSKapache2.xml /lib/svc/method/http-CSKapache2 # svccfg import /var/svc/manifest/network/http-CSKapache2.xml # svcadm -v enable CSKapache2 SMF for MySQL & Apache

16. Performance Tuning Which functions are being called by Drupal? # dtrace -n function-entry'{printf("called %s() in %s at line %d", copyinstr(arg0), copyinstr(arg1), arg2)}' -q How many times is a function called? # dtrace -n function-entry'{@[copyinstr(arg1)] = lquantize(arg2, 0, 5000)}' What's the file name and line number count: # dtrace -n function-entry'{@[copyinstr(arg1)] = lquantize(arg2, 0, 5000)}' Dtrace provider for PHP

17. Resource Management & Isolation Projects # projadd -c "Apache-PHP" -U webservd httpd.php # projmod -sK "project.max-sem-ids=(privileged,256,deny)" httpd.php # svccfg -s http:CSKapache2 setprop start/project = astring: httpd.php # svcadm -v enable CSKapache2 CPU Shares global# zonecfg -z zone1 zonecfg:zone1> add rctl zonecfg:zone1:rctl> set name=zone.cpu-shares zonecfg:zone1:rctl> add value (priv=privileged,limit=15,action=none) zonecfg:zone1:rctl> end zonecfg:zone1> exit Zones: data, configuration
