今天在Oracle 12.1.0.2.0 版本中RMAN 連接PDB 用戶時和連接CDB 顯示提示信息一樣connected to target database: CNDBA (DBID=215559030)懷疑自己是不是做錯了，檢查tnsname.ora 有以下內容並沒有錯，於是查視圖 v$pdbs 結果是對的，於是同樣的操作 在 Oracle 12.2.0.1.0 測試結果RMAN 連接PDB 目標庫是提示 connected to target database: CNDBA:PDBCNDBA (DBID=4271691857) 檢查 v$pdbs也是對的，Oracle 12.2.0.1.0 做了改進,可以直接提示連接PDB,不會誤導操作。
pdbcndba=
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.1.11)(PORT=1521))
(CONNECT_DATA=
(SERVICE_NAME=pdbcndba)
(SERVER=DEDICATED)
)
)
說明：以下實驗test 具有sysdba 權限，pdbcndba 是tnsname.ora 文件配置的連接PDB 的網絡服務名。
1） Oracle 12.1.0.2.0 數據庫中RMAN 連接CDB,PDB 目標庫操作，連接提示信息一樣。

2） Oracle 12.2.0.1.0 數據庫中RMAN 連接CDB,PDB 目標庫操作，連接成功的提示信息有區別，連接PDB 時提示 CDB 後面跟着PDB (CNDBA:PDBCNDBA)很明顯的知道連接到PDB
