在Oracle 12C上实施ACFS replication

在Oracle 12C上实施ACFS replication

环境: qc550705 & qc550707， AIX6.1+12c RAC

Primary FS： qc550705:/acfs3

Standby FS： qc550707:/acfsstd1

实施前提：primary FS的可用空间必须等于其已使用空间

以下是实施Replication的步骤：

1、 建立replication admin(一个节点上操作)

grid@qc550705:/home/grid>sqlplus "/as sysasm"

SQL*Plus: Release 12.1.0.1.0 Production on Fri Feb 14 16:24:33 2014

Copyright (c) 1982, 2013, Oracle. All rights reserved.

Connected to:

Oracle Database 12c Enterprise Edition Release 12.1.0.1.0 - 64bit Production

With the Real Application Clusters and Automatic Storage Management options

SQL> CREATE USER acfsrep1 IDENTIFIED BY "773946";

User created.

SQL> GRANT sysasm,sysdba TO acfsrep1;

Grant succeeded.。

2、 建立standby FS

--Add ACFS volume

SQL> select a.group_number,b.name,a.name,value from v$asm_attribute a,v$asm_diskgroup b where lower(a.name) like '%compatible%' and b.group_number=a.group_number;

GROUP_NUMBER NAME NAME VALUE

------------ ---------------------------------------- ---------------------------------------- ------------------------------

1 ACFSDG compatible.asm 12.1.0.0.0

1 ACFSDG compatible.rdbms 12.1.0.0.0

1 ACFSDG compatible.advm 12.1.0.0.0

2 SYSDG compatible.asm 12.1.0.0.0

2 SYSDG compatible.rdbms 10.1.0.0.0

SQL> alter diskgroup acfsdg add volume acfsvol_std1 size 16G unprotected stripe_columns 1;

Diskgroup altered.

SQL> quit
