When the question of what starts OSWatcher (OSW) on Exadata was raised at a client site and I thought I’d take a quick look. It took me a little longer than I expected to work out the detail and therefore it seems worth sharing.
If you’re simply looking to change the “snapshot interval”, “archive retention” or “compression command” then /opt/oracle.cellos/validations/init.d/oswatcher is what you need to modify and you’ll find a line with ./startOSW.sh X Y Z. Where X is the snapshot interval, Y is the archive retention and Z is the compression command used to compress the (more...)
I’m not sure exactly when this change happened, but in Oracle [Enterprise] Linux 5 days a default installation would result in the root file system being created as a LVM logical volume (LV) named LogVol00 in a volume group (VG) named VolGroup00. I must confess that I wasn’t paying too much attention to LV and VG default names in the days I was playing with OL5 a lot, but that’s partly because there was nothing to drag my attention to them.
Along comes Oracle Linux 6 and off I go creating VMs, cloning them and then really not liking the (more...)
At least one person asked me why I did this, so I’ll start by explaining the motivation for setting up my own mirror of Yum repositories freely available on public-yum.oracle.com.
It comes down to 5 main reasons:

It was pretty straightforward and this post is just a few references and hopefully enough information on the error messages I encountered (due to misconfiguration) to bring someone here that has made the same mistake. The existing DNS (master) server runs on Oracle Linux 6 and I wanted to setup a slave on Ubuntu 12.04. The site that I found most useful (more...)
