Planning to build a RAC on following environment.
Oracle Database Ver.: 188.8.131.52
OS: Linux RHEL 6.1 - 64 Bit
ASM and ACFS for storage.
Here need a advice: Is using ACFS for CFS is good idea or anything else better than this?
Thank you in advance:
Store EVERYTHING in ASM (datafiles, ocr, voting, redo, undo)
Use ACFS for datapump(expdp,impdp) DIRECTORIES, archivelogs and RMAN backups. This allows any node in the cluster to do the backups and then sweep these online backups to tape after the fact. This is supported as of 184.108.40.206.
Great to think of Oracle11g 220.127.116.11 RAC(Don't forget to install Patch 13440962) but do consider below
1.) Implementing ACFS is supported for Shared Oracle Home.
2.) ACFS is a good option for storing Backups(Ex. RMAN,Exports etc)
3.) Can be used as a NFS Shared drive for other NFS clients.
You will also see a resource "ora.registry.acfs" just after you start creating/using ACFS.
ACFS is cool to use using asmcmd commands or alter diskgroup sql statements.
ACFS is as better like other Vendor Cluster File system.
Please, allow a few comments:
1) This Oracle RAC SIG discussion might give you more data points for considering ACFS: http://lnkd.in/PD_RAb
2) 18.104.22.168 ACFS allows for storing backup sets for example. Now it is only a small step to support DB files on ACFS. ;-)
3) Every cluster file system requires a cluster underneath. The files for the cluster (clusterware files) cannot be stored on it.
3.1) Even for ASM, the Voting Files would be managed by ASM, but are accessed directly.
Just some comments. Thanks,
