The machine I have problems with had a single hard drive that contained the
OS, the registry, and the database; and after a lot of effort I am unable to
boot from this drive, but I installed a second drive with an OS and registry
and I boot from the new drive and then I can access the old drive. The
problem now however, is that the new registry does not know about the
database on the old drive, and therefore, the instance will not start.
Since I am unable to boot from the old drive, I thought that I could install
Oracle on the new drive to get the registry set properly, start an instance,
and some how point the database toward the existing .dbf files on the old
drive. Is this possible, or are there inherent reasons why this will not
work in Oracle? Or, is there a better solution?
