oracle 12c :5步开归档

查看归档状态：

[oracle@lemon01 ~]$ sqlplus / as sysdba;

Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production

SQL> archive log list;   
Database log mode              No Archive Mode
Automatic archival             Disabled
Archive destination            /u01/app/oracle/product/12.2.0/db_1/dbs/arch

1.创建归档目录

[oracle@lemon01 ~]$ mkdir arch

2.指定归档位置

SQL> alter system set log_archive_dest_1='LOCATION=/home/oracle/arch' scope=both;
alter system set log_archive_dest_1='LOCATION=/home/oracle/arch' scope=both
*
ERROR at line 1:
ORA-32001: write to SPFILE requested but no SPFILE is in use

报错显示：已请求写入spfile,但启动时未使用spfile

解决办法：（参考网上资料）

SQL> show parameter spfile;

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
spfile                               string
SQL> create spfile from pfile;

File created.

SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup 
ORACLE instance started.

再次执行报错的语句：

SQL> alter system set log_archive_dest_1='LOCATION=/home/oracle/arch' scope=both;

System altered.

3.关库，将库启到mount状态：

SQL> shutdown immediate; 
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup mount;
ORACLE instance started.

Total System Global Area  763363328 bytes
Fixed Size                  8625368 bytes
Variable Size             599786280 bytes
Database Buffers          150994944 bytes
Redo Buffers                3956736 bytes
Database mounted.

4.切归档

SQL> alter database archivelog;

Database altered.

5.开库，查归档状态

SQL> alter database open;

Database altered.

SQL> archive log list;
Database log mode              Archive Mode
Automatic archival             Enabled
Archive destination            /home/oracle/arch
Oldest online log sequence     21
Next log sequence to archive   23
Current log sequence           23

OK啦。

备注：上述报错是由于数据库开启时使用pfile参数文件启库，查看数据库用什么状态启库，可执行show parameter spfile,显示为空的时候，则是用pfile启动。可通过pfile文件创建spfile文件。

SQL> show parameter spfile;

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
spfile                               string      /u01/app/oracle/product/12.2.0
                                                 /db_1/dbs/spfileNAN.ora
