I am trying to figure out a solution to utilize NetApp snapmirror to setup
a DR site for the primary databases, which are two nodes Oracle RAC
databases with ASM, to replace Oracle Data Guard, which is currently being
used. The database servers on both primary and DR sites are Solaris 10.
The primary site database on Oracle 10.2 RAC with ASM. The DR database can
be on ASM or NFS, but I guess if using NetApp utility, such as snapmirror,
the database on DR site has to be on ASM, correct? I am also puzzling if DR
site has to mimic the primary setup and has to be two node RAC with ASM
since snapmirror copying redo logs from both instances from the primary
site.
If you have done similar setup, I'd appreciate if you could share some
technical details with me. Thank you in advance.
Two volumes are created on NetApp FAS3140. One is for Oracle cluster OCR
and voting disks, and the other is for Oracle ASM.
ASM configuration info:
Two diskgroups are created on 10 LUNs. One for database files (7 luns) and
the other is for Oracle FRA (3 luns).
