有 crs ，还要集群软件干嘛

[B]GPFS 方式和 ASM方式到底有什么区别呀？ [/B]

GPFS is General Parallel File System provided by IBM. It is equivalent to OCRS --Oracle Cluster File System on Linux or Windows.  Basically, it is a Cluster File System.  Regular File System is not capable of sharing one database among multiple nodes.

If you are going to implement 10gRAC on AIX, you have three storage options:
1.ASM
2.GPFS
3.Logical Raw Devices + HACMP

Oracle recommands ASM -- from performance and cost wise. I guess many shops have already adopted ASM in their 10gRAC +  AIX enviroments.   

10gRAC on AIX is not a very smooth ride.  We just completed our RAC POC -- Proof of Concept.  There are quite a few issues -- DBCA doesn't do cascade update, Service failover, 10.2 patch upgrade, etc, etc.  Oracle sent RAC specialist on-site, but still could not get over all the issues .

We were told only 200+ companies in North America are running RAC on AIX.  Not that many.  The majority RAC implementations are on Linux.  We did have a talk over the phone with a VP of Oracle RAC product.  He promised release 10.3 had already addressed some of the issues, which should be avaliable no later than early next year. The future still looks promising.

10.2已经不需要第三方软件了，就是存储 你得用ASM来管理。
这样少很多事情，在9i 如果你是dba，去装数据库，IBM，sun、hp veritas的集群软件都要懂
不太容易，得和系统工程师配合，经常是不知道问题出在cluster 软件还是 oracle这边头都大。
