I have three database on a single NT server running 8.1.5.
Assume they are called:
database1
database2
database3

If I want to upgrade to 8.1.7, do I have to set the
ORACLE_SID to database1 finish the upgrade
then set ORACLE_SID to database2 finish the upgrade
then set ORACLE_SID to database3 in that order?
I do not think that you can upgrade all the three SID's during just one single upgrade, since you have to specify the SID name during the upgrade.

I have read all the docs on upgrade but it does not specify this.
