Hi,
we need to implement a high availibility architecture for database side (Oracle 12 c on Linux).
We plan to use Oracle RAC and for DRP (disaster recovery plan on a remote secondary site) we think about Oracle data guard.
Is it necessary to have both Oracle RAC and dataguard on both sites ?
Is Oracle extended RAC an option ?
The customer uses VPLEX (EMC solution) to replicate data from san storage, so it is necessary to use Oracle data guard ?
Thanks a lot
