RAC修改spfile位置

[root@rac1 ~]# su - oracle
[oracle@rac1 ~]$ sqlplus  / as sysdba

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
State    Type    Rebal  Sector  Block       AU  Total_MB  Free_MB  Req_mir_free_MB  Usable_file_MB  Offline_disks  Voting_files  Name
MOUNTED  NORMAL  N         512   4096  1048576      6144     5218             2048            1585              0             Y  OCRDG/
MOUNTED  EXTERN  N         512   4096  1048576    204800   204704                0          204704              0             N  ORCLDG/
MOUNTED  EXTERN  N         512   4096  1048576    204800   204704                0          204704              0             N  ORCL_FRA/

ASMCMD> cd ORCL_FRA
ASMCMD> ls
ORCL/
ASMCMD> cd orcl
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
