Explanation/Reference:
查看数据库是否为归档模式: SYS@ENMOEDU> archive log list Database log mode No Archive Mode Automatic archival Disabled Archive destination USE_DB_RECOVERY_FILE_DEST Oldest online log sequence 1 Current log sequence 2
关闭数据库: SYS@ENMOEDU> shutdown immediate Database closed. Database dismounted. ORACLE instance shut down.
数据库启动到mount: SYS@ENMOEDU> startup mount ORACLE instance started. Total System Global Area 421724160 bytes Fixed Size 2253864 bytes Variable Size 322964440 bytes Database Buffers 88080384 bytes Redo Buffers 8425472 bytes Database mounted.
修改数据库为归档模式: SYS@ENMOEDU> alter database archivelog;
Database altered.
打开数据库: SYS@ENMOEDU> alter database open;
Database altered.
再次查看归档模式: SYS@ENMOEDU> archive log list Database log mode Archive Mode Automatic archival Enabled Archive destination USE_DB_RECOVERY_FILE_DEST Oldest online log sequence 1 Next log sequence to archive 2 Current log sequence 2
