Moving from Raw file system to Cooked

We are moving our oracle database and hardware from a raw file system to a cooked file system. What are the O/S steps ? Are there any references to read or look at to assist us in the move ? We need to preserve the data, hopefully no export / import will have to be done for the move !

Re: Moving from Raw file system to Cooked

Which Oracle version do you use. If Oracle 8/9, perhaps RMAN can be used as an alternative.
See the chapter "Create a duplicate database with Recovery manager" in the RMAN manual

Re: Moving from Raw file system to Cooked

I have never done this, but here's what I think:

The internal format for mounted and raw file systems is COMPLETELY DIFFERENT.

You are going to have to:

1. build completely new mounted file systems the size and name you want:


mkdir mtpoint
vi /etc/fstab
mount -a

2. export all the raw data to exportfiles,
3. and then import the raw data into your new file systems.

You should expect:
Complete rebuild.
Hours of downtime.
