我無法在命令列上登錄 Oracle 19c DB。這是我得到的錯誤：
PS C:\Windows\system32> sqlplus / as sysdba

如果我檢查監聽器的狀態，它看起來像是在運行（除非我弄錯了）：

The command completed successfully
但是，我可以使用 SQL Developer 登錄并運行查詢：
如果我嘗試啟動該服務，它會說它已經啟動：
PS C:\Users\bluet> net start OracleServiceAWS
The requested service has already been started.
More help is available by typing NET HELPMSG 2182.
我真的很好奇為什么我無法在命令列和 Oracle SQL 開發人員中登錄，這很好！我想更正這個問題，以便我可以在命令列上再次登錄。
uj5u.com熱心網友回復：
看起來您必須指定要連接的容器。例如：
sqlplus sys/its_password@pdb as sysdba
----
this is your pluggable database
