Upgrading an Amazon EC2 Delphix Source, Part I

For a POC that I’m working on with the DBVisit guys, I needed a quick, 12c environment to work on and have at our disposal as required.  I knew I could build out an 11g one in about 10 minutes with our trust free trial, but would then need to upgrade it to 12c.

Disable snapshots to Delphix Engine

This is a simple prerequisite before you upgrade an Oracle source database and takes down the pressure on the system, as well as confusion as the database upgrades the Oracle home, etc.

Simply log into the Delphix Admin console, click on your source group that the source database belongs to and under Configuration, in the right hand side, you’ll see a slider that needs to be moved to the “disable” position to no longer take interval snapshots.

Configuring VNC Server on Fedora 16…

When Fedora 15 rocked up it brought with it a replacement for the old init-style startup called systemd. In Fedora 15, it was pretty easy to ignore this change as everything (including vncserver) ran pretty much the same as before.

Fedora 16 is a little more “aggressive” about it’s use of systemd. When you issue and old-style service command, you are in no doubt that things have changed.

[root@homer system]# service nfs stop
Redirecting to /bin/systemctl  stop nfs.service
[root@homer system]#

Once again, not a big deal in itself.

So that brings me to the reason for this post. The configuration of VNC Server has changed completely between Fedora 15 and Fedora 16. By default you can’t get away with editing the “/etc/sysconfig/vncservers” file anymore. That issue prompted me to knock up a quick article to remind myself how to do the systemd-style setup.
