Re: Conversion of a 3 TB NON-RAC Database To "ASM" - RAC in 10gR2 ?

On otn.oracle.com there is a high availability section - MAA - it
contains quite a few documents that should help you out on this.

With respect to downtime, we converted a 9i db to RAC - using a similar method documented in the maa docs. Which allowed us to perform the task in under an hour. The db was 1.3 TB and it also had to be migrated to a new SAN.

Folks
 

  
 

What could be the approach to Convert a Large
3 TB NON-RAC Production Database with Datafiles existing
on cooked/Mounted Filesystem (UFS)
to a 3 instance RAC using “ASM”?
 

  
 

NOTE – Production Database is Near
24*7 with Minimal Downtime.
 

  
 

Can
the Datafiles be copied using “dd” Command from the Mounted FS to
the RAW Device Space of ASM?
 

  
 

Need
the basic approach Steps for conversion.
 

  
 

Any
Docs, pointers, Links will help. (Did
search Oracle Documentation, but could NOT find a practical Hands-On Note)
 

  
 

Config:-
 

---------
 

Solaris 10
 

Oracle 10gR2
 

3 instance RAC
 

  
 

Thanks indeed
