AIX RAC配置Flashback Recovery Area
环境：
操作系统： AIX 5300-09
集群软件： CRS 10.2.0.1
数据库： Oracle 10.2.0.1
本案例是用于基于VG Concurrent 的共享存储，通过HACMP 实现卷组的并发
由于共享存储采用了并发卷组，在上面不能建立文件系统；并且Flashback Recover Area亦不能建立在raw上，所以在本地卷组上建立文件系统，通过NFS共享方式来建立Flashback Recover Area。
1、在node1上建立文件系统
[root@aix211 /]#lsvg rootvg
VOLUME GROUP: rootvg VG IDENTIFIER: 00040f8a00004c0000000140c6da55a7 VG STATE: active PP SIZE: 128 megabyte(s) VG PERMISSION: read/write TOTAL PPs: 546 (69888 megabytes) MAX LVs: 256 FREE PPs: 190 (24320 megabytes) LVs: 17 USED PPs: 356 (45568 megabytes) OPEN LVs: 16 QUORUM: 2 (Enabled) TOTAL PVs: 1 VG DESCRIPTORS: 2 STALE PVs: 0 STALE PPs: 0 ACTIVE PVs: 1 AUTO ON: yes MAX PPs per VG: 32512 MAX PPs per PV: 1016 MAX PVs: 32 LTG size (Dynamic): 256 kilobyte(s) AUTO SYNC: no HOT SPARE: no BB POLICY: relocatable
[root@aix211 /]#smit crfs
[root@aix211 /]#df -m

[root@aix211 /]#chown -R oracle:dba /flash_rcy
2、配置Flashback Directory共享
[root@aix211 /]#cat /etc/exports
/soft2 -sec=sys:krb5p:krb5i:krb5:dh,rw,access=aix212:aix199
/flash_rcy -sec=sys:krb5p:krb5i:krb5:dh,rw,root=aix212
3、在node2上配置共享访问Flashback Directory
[root@aix212@ /]#cat /etc/filesystems
/flash_rcy: dev = "/flash_rcy" vfs = nfs nodename = 192.168.8.211 mount = true options = rw,bg,hard,intr,proto=tcp,vers=3,rsize=65536,wsize=65536,timeo=60 0 account = false
[oracle@aix212@ /]$mkdir /flash_rcy
[root@aix212@ /]#ls -ld /flash_rcy
drwxr-sr-x 4 oracle dba 512 Aug 7 15:44 /flash_rcy
[root@aix212@ /]#mount /flash_rcy
[oracle@aix212@ ~]$mount
node mounted mounted over vfs date options
-------- --------------- --------------- ------ ------------ ---------------
192.168.8.211 /flash_rcy /flash_rcy nfs3 Aug 07 15:53 rw,bg,hard,intr,proto=tcp,vers=3,rsize=65536,wsize=65536,timeo=60
4、配置Flashback Recovery Area
SQL> show parameter recovery NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ db_recovery_file_dest string /flash_rcy db_recovery_file_dest_size big integer 2G
5、测试Flashback Recovery Area
[oracle@aix212@ ~]$rman target / Recovery Manager: Release 10.2.0.1.0 - Production on Thu Aug 7 15:53:31 2014 Copyright (c) 1982, 2005, Oracle.

@默认，RMAN备份存储到Flashback Recovery Area，至此Flashbackup Recovery Area配置完成！

Additional information: 6
解决方法：
在/etc/filesystems配置mount参数：
[root@aix212@ /]#cat /etc/filesystems
/flash_rcy: dev = "/flash_rcy" vfs = nfs nodename = 192.168.8.211 mount = true options = rw,bg,hard,intr,proto=tcp,vers=3,rsize=65536,wsize=65536,timeo=60 0 account = false
@重新mount后，问题解决 ！
