Goran,
We are using both SRDF/A and Server Cloning Processes for replication.
The process is fairly simple with the most of the coding/scripting effort .
One of the Issues we've encounted is while the Clone process is running There
is
a very high amount of I/O Being Done as the Disk Frame level. Since a clone
can only be done in the Same Frame level. This can cause Database Bottlenecks
albeit for a small period of time .
We've Move to Data guard due to these issues.
May i Ask what is the requirement . If Offloading Backups is the need. I've
found Physical Dataguard to be better than EMC Cloning.
SRDF/A is a different product set from EMC and it allows for between
Frame/Datacenters replication. It is a fairly costly solution though.
While Oracle will certify an Oracle Database Running on an EMC Frame. It will
not certify a 3rd Part product.
The technology is called Split mirror and the EMC Product is Time Finder.

Hi all,
at the place where I work, management would like to implement EMC Replication
(as we have EMC SAN's) for our databases between two Data Centers instead of
DataGuard for certain DB-systems.
According to EMC sales, the process is certified by Oracle although I didn't
find any reference on Metalink (could be also, I didn't search it well).
If someone (out there ;-) ) is already using it, I would appreciate if you
could
tell me your experiences and possible pitfalls regarding implementation.
Best Regards,
Goran
