15. SQL> show parameter db_name
16. NAME                                 TYPE                   VALUE
17. ------------------------------------ ---------------------- ------------------------------
18. db_name                              string                  orcl
19. 1.查看当前的DATABASE spfile 位置
20. SQL> show parameter spfile
21. NAME                                 TYPE        VALUE
22. ------------------------------------ ----------- ------------------------------
23. spfile                               string      +ORCLDG/orcl/spfileorcl.ora
24. 2.备份 pfile
25. [oracle@rac1 ~]$ cd $ORACLE_HOME/dbs
26. [oracle@rac1 ~]$ more initorcl1.ora
27. spfile='+ORCLDG/orcl/spfileorcl.ora'
28. [oracle@rac1 ~]$ cp initorcl1.ora  initorcl1.orabak
29. 3.重新在指定路径创建 spfile
30. [oracle@rac1 ~]$ sqlplus / as sysdba
31. SQL> create  pfile from spfile;
32. SQL> create spfile='+ORCL_FRA' from pfile;
33. 4.查看新创建spfile位置
34. [oracle@rac1 ~]$ su - grid
35. [grid@yyzfrac1 ~]$ asmcmd
36. ASMCMD> lsdg
37. State    Type    Rebal  Sector  Block       AU  Total_MB  Free_MB  Req_mir_free_MB  Usable_file_MB  Offline_disks  Voting_files  Name

41. ASMCMD> cd ORCL_FRA
42. ASMCMD> ls
43. ORCL/
44. ASMCMD> cd orcl
45. ASMCMD> ls
46. CONTROLFILE/
47. PARAMETERFILE/
48. control01.ctl
49. control02.ctl
50. ASMCMD> cd PARAMETERFILE/
51. ASMCMD> ls
52. spfile.258.836345535
53. 5.指定新的spfile别名
54. ASMCMD>mkalias +ORCL_FRA/ORCL/PARAMETERFILE/spfile.258.836345535   +ORCL_FRA/ORCL/spfileorcl.ora
55. 6.用srvctl修改新的rac数据库spfile 位置
56. [oracle@yyzfrac2 dbs]$ srvctl  modify database -d orcl -p +orcl_fra/orcl/spfileorcl.ora
57. 7.删除原来的spfile
58. [oracle@rac1 ~]$ sqlplus / as sysdba
59. SQL>alter diskgroup orcldg drop file '+orcldg/orcl/spfileorcl.ora';
60. 8.分别在两个节点中更新initorcl1.ora initorcl2.ora
61. 内容为spfile='+orcl_fra/orcl/spfileorcl.ora'
62. 9.重新启动数据库
63. [oracle@rac1 ~]$srvctl stop database -d orcl
64. [oracle@rac1 ~]$srvctl start database -d orcl
65. 10.在两节点查看spfile位置
66. SQL> set line 3000
67. SQL> show parameter spfile
68. NAME                                 TYPE        VALUE
