“rman target /” 和 “rman nocatalog target /” 区别

原创 Linux操作系统 作者:yxyup 时间:2009-10-20 16:24:20 0 删除 编辑

刚才在itpub上看到一贴 “rman target /” 主要是对 “rman target /” 和 “rman nocatalog target /”这两种方式连接有些疑惑.

正好偶以前也发现这样的问题,于是将N久前的笔记翻出,又重新测试了一下,详细如下,hehe.

rman target / 是连接了 target DB并进入了rman环境,这时还可以连接 catalog DB
rman nocatalog target /  是以nocatalog模式连接进入了target DB,这时是不可以再连接catalog DB了

详细如下

oracle@dbatest1:/home/oracle #rman target /
