Re: Question re Database Duplication

I believe you can do this using RMAN.... Off the top of my head:

1. Upgrade to 10.2.0.4 in place on the 32 bit box. Upgrade the EE at the same 
time.

2. Use the transportable tablespace features of Oracle to move the datafiles. I 
think (though I've never done it) that you can move the datafiles from 32-bit 
to 64-bit without converting them. Looking at some Doc this appears to be the 
case, but I'd do a small test first to be sure. If you have to convert you can 
use RMAN and cross-platform transportable tablespaces, move from the 32 bit box 
to the 64 bit box.

3. Fire it up.

Bada boom, you are done.

Subject: Question re Database Duplication

Greetings,

One of my databases is Oracle 10.2.0.3.0 SE running on 32-bit RHEL4. I am 
building a new server running 64-bit RHEL4 and I will install Oracle 10.2.0.4.0 
EE on this server. My goal is to move the existing database to the new server. 
I am hoping to do this using the cloning feature of the OEM provisioning pack 
and wondering if this will work smoothly. The concerns I have are

1) going from 32-bit to 64-bit
2) going from 10.2.0.3 to 10.2.0.4
3) going from SE to EE

I am pretty certain this isn't going to work, I don't believe OEM and RMAN have 
the intelligence built in to make the changes and I suspect I will have to use 
expdp/impdp but am just wondering if anyone has any further thoughts. 
Unfortunately I don't have an environment in which to test this.

Thanks.
