客戶端連接oracle的時候時而連得上時而連不上 而且報錯不是ora-12545，是報的ora-12541沒有監聽

連指定節點能連得上沒問題，

SQL> conn sys/oracle@cbl1 as sysdba

Connected.

SQL> conn sys/oracle@cbl2 as sysdba

Connected.

SQL> conn sys/oracle@cbl as sysdba

Connected.

SQL> conn sys/oracle@cbl as sysdba

ERROR:

ORA-12541: TNS:no listener

我懷疑是不是監聽動態注冊的有問題，誰能幫我看看
