“rman target /” 和 “rman nocatalog target /” 區別

剛才在itpub上看到一貼 “rman target /” 主要是對 “rman target /” 和 “rman nocatalog target /”這兩種方式連線有些疑惑.

正好偶以前也發現這樣的問題,於是將N久前的筆記翻出,又重新測試了一下,詳細如下,hehe.

rman target / 是連線了 target DB並進入了rman環境，這時還可以連線 catalog DB
rman nocatalog target /  是以nocatalog模式連線進入了target DB，這時是不可以再連線catalog DB了

詳細如下

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