一、数据库启动和关闭
启动：
1.startup ; 启动实例，打开数据库，启动数据库
2.startup mount; 启动实例，打开数据库
3.startup unmount; 启动实例
关闭：
1.shutdown normal; 处理用户提交的所有事务，等待用户退出连接后，关闭数据库、卸载数据库，关闭实例。在下次启动实例时，不做实例恢复操作。
2.shutdown immediate; 结束正在处理的SQL语句，回滚末提交事务、不等待用户退出正常连接。在下次启动实例时，做实例恢复操作。

二、停止online backup
1、杀进程，并在sm37中cancel;如果不行，还是停不掉的话在SQL下执行以下命令：alter tablespace PSAPQAS end backup;

三、删除不用的tablespace
1、SQL> DROP TABLESPACE PSAPROLL including contents and datafiles;

Tablespace dropped.
2、SQL> select name from v$datafile;
