Good day to you all.

A tad baffled as to what is the correct method of installing and updating
OES linux.

I have the OES Linux media and start the install off with this. I then
apply OES sp2 followed by command line RUG updates for OES Channel. Is
this correct?

Read elsewhere that you need to install SLES sp3 prior to applying OES sp2.

Your advise please ladies and gentlemen.
