rman备份恢复命令之switch(转)
一 switch 命令
1 switch命令用途
更新数据文件名为rman下镜像拷贝时指定的数据文件名
更新数据文件名为 set newname 命令指定的名字。
2 switch 命令使用前提条件
rman 必须连接到目标数据库
当switch tablespaces、datafiles、tempfiles时，这些文件必须离线
当switch 整个数据库时，数据库不能open
3 注意事项
switch....to copy 命令用于rman命令提示符下
switch没有to copy的命令用于run语句块中
4 语法
第一组
switch dtabase to copy;
switch datafile number|name to copy;
switch tablespace name to copy;
第二组
switch datafile all;
switch datafile number|name;
switch tempfile all;
二 举例如下：
例一：用switch datafile number to copy 更新数据文件位置和名字
RMAN> backup as copy datafile 8 format '/oracle/CRM/test.dbf';
