ORA-32000: write to SPFILE requested but SPFILE is not modifiable

ORA-32000: write to SPFILE requested but SPFILE is not modifiable

遇到这种问题，肯定是spfile与pfile 出了问题

1.startup pfile='/home/oracle/pfile_xxx.ora';

在成功后，

2.su- grid

asmcmd

删除spfile_xxx.ora

3.sqlplus / as sysdba

create spfile='+DGDATA01/XXX/spfile_xxx.ora' from pfile='/home/oracle/pfile_xxx.ora';

查看+DGDATA01/XXX/spfile_xxx.ora 是否生成。

4.$ORACLE_HOME/dbs下的spfile_xxx.ora 先改为bak， mv spfile_xxx.ora spfile_xxx.ora_bak

因为启动顺序

spfile${ORACLE_SID}.ora > spfile.ora > init${ORACLESID}.ora

6. 重新启动

SQL>  startup force;
ORACLE instance started.

SQL> exit

7.重启动检查

SQL> show parameter spfile
