Oracle 9i 非归档模式到归档模式设置一例

创建归档目录：-
 

[Oracle@ORA9ISERV arch]$ mkdir -p /u01/app/oracle/oradata/orcl/arch

设置log_archive_dest_1参数：

SQL> alter system set log_archive_dest_1='LOCATION=/u01/app/Oracle/oradata/orcl/arch' scope=both;

System altered.

查看log_archive_dest_1设置：

SQL> show parameter log_archive_dest_1

NAME                                 TYPE                   VALUE

------------------------------------ ---------------------- -------

log_archive_dest_1                   string                 LOCATION=/u01/app/Oracle/orada

ta/orcl/arch

SQL> show parameter log_archive_dest_state_1

NAME                                 TYPE                   VALUE

------------------------------------ ---------------------- -------

log_archive_dest_state_1             string                 enable

切换日志:

SQL> alter system switch logfile;

System altered.

SQL> select sequence#,dest_id,archived,applied,deleted, status,first_time from v$archived_log order by sequence#;

no rows selected

观察并没有产生归档。

查看数据库归档模式：

SQL> archive log list

Database log mode              Archive Mode

Automatic archival             Disabled   --不解

Archive destination            /u01/app/Oracle/oradata/orcl/arch

Oldest online log sequence     4

Next log sequence to archive   4

Current log sequence           6

Google：修改pfile参数文件，设置log_archive_start='TRUE'

SQL> create pfile from spfile;

File created.

添加：log_archive_start='TRUE'

*.log_archive_dest_1='LOCATION=/u01/app/Oracle/oradata/orcl/arch'

log_archive_start='TRUE'

SQL> create spfile from pfile;

File created.

重启数据库：

SQL> startup

Oracle instance started.

归档已经产生。

查看归档目录是否有归档文件产生：

[Oracle@ORA9ISERV arch]$ pwd

/u01/app/Oracle/oradata/orcl/arch

[Oracle@ORA9ISERV arch]$ ls -l

total 1124
