More detailed instructions can be found here, but below are the steps I use.
Note – All instructions assume the SAS is installed on a linux box, in /usr/local/, since that’s where it was installed on my machine.
Stop all JBoss server instances
/usr/local/jboss-5.1.0.GA/bin/SASServer1.sh stop
Stop SAS processes
/usr/local/config/Lev1/sas.servers stop
Start SAS processes
/usr/local/config/Lev1/sas.servers start
(wait a couple of minutes)
Start JBoss server instances
/usr/local/jboss-5.1.0.GA/bin/SASServer1.sh start
(wait about 5, 10 minutes)
