AIX RAC配置Flashback Recovery Area

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

[root@aix211 /]#smit crfs

[root@aix211 /]#df -m

/dev/lv05????????128.00????123.94????4%???????17?????1%?/flash_rcy

[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,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,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?/

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

错误案例：访问Flashback Recovery Area失败

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,timeo=60
0
????????account?????????=?false

@重新mount后，问题解决 ！
