【步骤2】查看当前归档模式，是归档还是非归档
SQL archive log list;
Database log mode No Archive Mode
Automatic archival Disabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 228
Current log sequence 230
【步骤3】关闭数据库
SQL shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
【步骤4】启动数据库到mount状态
SQL startup mount;
ORACLE instance started.

Variable Size 2013268544 bytes
Database Buffers 1392508928 bytes
Redo Buffers 16007168 bytes
Database mounted.
【步骤5】启动归档模式
SQL alter database archivelog;
Database altered.
SQL archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 228
Next log sequence to archive 230

【步骤6】启动数据库
SQL alter database open;
Database altered.
【步骤7】关闭归档模式
SQL shutdown immediate;
Database closed.
Database dismounted.

如果开启归档，请保证log_archive_start=true开启自动归档，否则只能手工归档，如果是关闭了归档，则设置该参数为false 注意：如果是OPS/RAC环境，需要先把parallel_server = true注释掉，然后执行如下步骤，最后用这个参数重新启动 1、开启归档 a. 关闭数据库shutdown immediate b. startup mount c. alter database archivelog d. alter database opne 2、禁止归档 a. 关闭数据库shutdown immediate b. startup mount c. alter database noarchivelog d. alter database open 归档信息可以通过如下语句查看 SQL archive log list Database log mode Archive Mode Automatic archival Enabled Archive destination E:\oracle\ora92\database\archive Oldest online log sequence 131 Next log sequence to archive 133 Current log sequence 133
开启/关闭归档： （1）关闭数据库 shutdown immediate; （2）启动数据库到mount状态 startup mount; （3）开启/关闭归档 开启：alter database archivelog; 关闭：alter database noarchivelog; （4）打开数据库 alter database open;
