oracle 增加控制文件

oracle 增加控制文件
1、看control_file路径

SQL> show parameter control

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
control_file_record_keep_time        integer     7
control_files                        string      /inspur/app/oracle/oradata/orc
                                                 l/control01.ctl, /inspur/app/o
                                                 racle/oradata/orcl/control02.c
                                                 tl
control_management_pack_access       string      DIAGNOSTIC+TUNING

2、复制控制文件

关库
SQL> shu immediate
到控制文件目录下
cd /inspur/app/oracle/oradata/orcl

复制一个命名control03.ctl
cp control01.ctl control03.ctl

3、修改spfile

启动到nomout状态
SQL> startup nomount

alter system set control_files = '/inspur/app/oracle/oradata/orcl/control01.ctl','/inspur/app/oracle/oradata/orcl/control02.ctl','/inspur/app/oracle/oradata/orcl/control03.ctl' scope=spfile;

4、确认增加成功

重新起库，数据库正常
SQL> shu immedaite
SQL> startup

SQL> show parameter control_files

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
control_files                        string      /inspur/app/oracle/oradata/orc
                                                 l/control01.ctl, /inspur/app/o
                                                 racle/oradata/orcl/control02.c
                                                 tl, /inspur/app/oracle/oradata
                                                 /orcl/control03.ctl
