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 /
