SQL> select status from gv$instance;

STATUS

OPEN

OPEN

SQL> show parameter db_name

NAME TYPE VALUE

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

db_name string orcl

1.查看当前的DATABASE spfile 位置

SQL> show parameter spfile

NAME TYPE VALUE

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

spfile string +ORCLDG/orcl/spfileorcl.ora

2.备份 pfile

[oracle@rac1 ~]$ cd $ORACLE_HOME/dbs

[oracle@rac1 ~]$ more initorcl1.ora

spfile='+ORCLDG/orcl/spfileorcl.ora'

[oracle@rac1 ~]$ cp initorcl1.ora initorcl1.orabak

3.重新在指定路径创建 spfile

[oracle@rac1 ~]$ sqlplus / as sysdba

SQL> create pfile from spfile;

SQL> create spfile='+ORCL_FRA' from pfile;

4.查看新创建spfile位置

[oracle@rac1 ~]$ su - grid

[grid@yyzfrac1 ~]$ asmcmd

ASMCMD> lsdg

ASMCMD> ls

ASMCMD> ls

CONTROLFILE/

PARAMETERFILE/

control01.ctl

control02.ctl

ASMCMD> cd PARAMETERFILE/

ASMCMD> ls

spfile.258.836345535

5.指定新的spfile别名

ASMCMD>mkalias +ORCL_FRA/ORCL/PARAMETERFILE/spfile.258.836345535 +ORCL_FRA/ORCL/spfileorcl.ora

6.用srvctl修改新的rac数据库spfile 位置

[oracle@yyzfrac2 dbs]$ srvctl modify database -d orcl -p +orcl_fra/orcl/spfileorcl.ora

7.删除原来的spfile

[oracle@rac1 ~]$ sqlplus / as sysdba

SQL>alter diskgroup orcldg drop file '+orcldg/orcl/spfileorcl.ora';

8.分别在两个节点中更新initorcl1.ora initorcl2.ora

内容为spfile='+orcl_fra/orcl/spfileorcl.ora'

9.重新启动数据库

[oracle@rac1 ~]$srvctl stop database -d orcl

[oracle@rac1 ~]$srvctl start database -d orcl

10.在两节点查看spfile位置

SQL> set line 3000

SQL> show parameter spfile

NAME TYPE VALUE

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

spfile string +ORCL_FRA/orcl/spfileorcl.ora
