关于Oracle归档与非归档(存档)模式命令

sqlplus /nolog;

sqlplus /nolog;

 

conn / as sysdba;

conn / as sysdba;

这样就进入了sqlplus的里面；如果你的数据库处于打开状态，那么请执行：

shutdown immediate;

shutdown immediate;

 

执行完以后的步骤后，就要开始进行归档模式与非归档模式之间的转换了：

startup mount;

startup mount;

 

归档->非归档

alter database noarchivelog;

alter database noarchivelog;

 

非归档->归档

alter database archivelog;

alter database archivelog;

 

检查是否成功：

Sql代码

archive log list;

      在执行startup mount;SQL代码时可能会遇到提示：ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务。

      遇到上面问题请在oracle\product\10.2.0\db_1\NETWORK\ADMIN目录下找到listener.ora文件，然后修改

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = E:\oracle10\product\10.2.0\db_1)
      (PROGRAM = extproc)
    )
   )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = TEST-HJ)(PORT = 1521))
    )
  )

为：

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = E:\oracle10\product\10.2.0\db_1)
      (PROGRAM = extproc)
    )
    (SID_DESC   =
       (GLOBAL_DBNAME   =   ORCL)
       (ORACLE_HOME   =   E:\oracle\product\10.2.0\db_1)      
       (SID_NAME   =   ORCL)
     )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = TEST-HJ)(PORT = 1521))
    )
  )

上述SID为orcl，如果为其他SID请填写对应SID即可，保存并覆盖原有文件，重启实例后再运行上面的命令即可。
