    user498566

            Are you using 2 or more real machines? You can use VM environments then use a Shared Disk configuration to create RAC config.

              Thanks to All,

              I have already created RAC with vmware on dedicated machine. I created two RAC node on vmware (RAC1, RAC2) but somehow it's not stable. Now I am planning to create RAC with two node cluster (real machines) with oracle certified shared storage device. I was looking that option if any such shared storage device is available in market which is less expensive.

                Two options:

                The Oracle VM templates can be used to build clusters of any number of nodes using Oracle Database 11g Release 2, which includes Oracle 11g Rel. 2 Clusterware, Oracle 11g Rel. 2 Database, and Oracle Automatic Storage Management (ASM) 11g Rel. 2, patched to the latest, recommended patches.

                This is supported for Production.

                  Yes. Firewire 800 external drive with dual ports, allowing 2 servers to connect (via Firewire) to the same drive. LaCie drives (1TB and up) starts at $200.

                  Assuming your servers/PCs do not have Firewire, then 2 Firewire PCI cards are also needed - pricing is less than $40 locally.

                  You also need the Firewall Linux kernel driver, configured to allow shared ("non-exclusive logon") connection to the Firewire drive. This was problematic back on RHEL3, but I assume that these problems have since been sorted in the 2.6 kernel tree.

                  Have not seen a cheaper (real h/w) shared storage solution than this. And it should suffice for a R&D style 2 node RAC.
