I got a question about the database location:
"Ops Center installs an embedded Oracle database in /var, but we'd like to move it to another directory. Is this possible?"
So, theoretically you could change the location on an embedded database, by stopping the EC and doing some ZFS juggling to move the /var/opt/sun/xvm/oracle directory contents to a new directory and mounting it to /var/opt/sun/xvm/oracle, but there's an easier (and officially supported) way to do this.
The officially supported way is to switch to a customer-managed database. This database can be located anywhere you want, so you can give it as much space as you need.
