Hi there,
Quick question following up on this thread:
After you to take the snapshot how do you backup the snapshot ASM volumes (they
are still RAW)?
Do you use DD or ASMCMD or any other way?
If we need to use asmcmd that would require an Oracle license. I am trying to
avoid that.
Thanks

With split-mirroring or snapshot solutions (EMC or NETAPP or anyother vendor)
when working with ASM you need to carefully layout the Disk Groups.
For example you should (or shall I say must) NOT mix databases in same Disk
Groups, because when you run the snapshot you will be backing up all databases
in the Disk Group, that is not a problem. The problem is when you have to
restore, when you restore a snapshot you will be restoring several databases!
Thanks

What kind of limitations are you referring to? Could you share a few more
areas/details?

Any major issues you ran into?
Thanks again
