SQL> show parameter db_name

------------------------------------ ---------------------- ------------------------------
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> 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
