- 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

- 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
