Configure SFRAC on Windows
Hi,
I am trying to configure SFRAC on Windows 2008 R2. I didn't find a solution of SFRAC for windows. I know that SFWHA is active/passive. But SFRAC is active/active, and it uses CVM rather than VxVm. I wonder if there is anyway can make the Oracle DB and shared disks active/active on Windows? Thanks a lot.
I don't think this is possible. According to post https://www-secure.symantec.com/connect/forums/multiple-luns-disk-group the last comment by jdangelo_symc says
Support for Multinode Disk Group Access was added to SFW 6.0. This could be categorized as CVM for Windows (Not CFS however).
However, looking at SFW release notes this says:
A new mode, Deported Read-Only, is added to the existing dynamic disk groupentity. In this mode, a disk group is imported in a Read-Only mode on all thepassive nodes. The disk group configuration on the active node is automaticallyreflected on the passive nodes. During failover, instead of a complete diskgroup deport and Read/Write import, only a mode change occurs on the passivenode.So this is not quite CVM as it does not allow you to write simultaneously from multiple nodes which is what RAC requires. But anyway, one of the main points of putting RAC on SF is that you get raw like performance using files, but Windows does not suport vxfs, so this is not possible even if you had "real" CVM on windows.On UNIX, the same Oracle agent is used to start Oracle in failover Oracle and RAC, so you MAY be able to put RAC under VCS control in Windows, but not SF control.Mike
