Hello, What are the best practices of RAID configuration of HDS 9960 storage and Oracle. Currently we are using now Mirroring RIAD 1+0 with 4 disks (2+2). will the second option of Mirroring 4+4 give us better performance than 2+2 disks? Thanks in advance. P.S. the Oracle instance is OLTP.
while using OLTP in Oracle 10g stanadard edition, does row level locking happen? What are its benefit?
