1.檢查資料庫狀態


[oracle@szdb product]$ sqlplus /nolog


SQL*Plus: Release 19.0.0.0.0 - Production on Fri Oct 29 14:48:12 2021

Version 19.12.0.0.0

SQL> conn / as sysdba

Connected.

SQL> SELECT name,open_mode from v$database;


NAME      OPEN_MODE

--------- --------------------

EMREP     READ WRITE


SQL>


2.檢視監聽服務:


[oracle@szdb product]$ lsnrctl status


LSNRCTL for Linux: Version 19.0.0.0.0 - Production on 29-OCT-2021 14:49:45


Copyright (c) 1991, 2021, Oracle.  All rights reserved.


Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=szdb)(PORT=1521)))

STATUS of the LISTENER

Listener Parameter File   /u01/app/oracle/product/19.12.0/db_1/network/admin/listener.ora

Listener Log File         /u01/app/oracle/diag/tnslsnr/szdb/listener/alert/log.xml

Listening Endpoints Summary...

(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=szdb)(PORT=1521)))

The listener supports no services

The command completed successfully

[oracle@szdb product]$


沒有任何服務


預設動態註冊服務。

3. 檢視local_listener引數

SQL> show parameter local_listener


NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

local_listener                       string      LISTENER_EMREP

SQL>


4.確認TNSNAMES.ORA中存在連線串


[oracle@szdb admin]$ pwd

/u01/app/oracle/product/19.12.0/db_1/network/admin

[oracle@szdb admin]$

[oracle@szdb admin]$

[oracle@szdb admin]$ grep -i listener_ tnsnames.ora

LISTENER_ORCLCDB =


不存在


5.修改LOCAL_LISTENER,去掉

SQL> alter system set local_listener='';


System altered.


--馬上註冊一下

SQL> alter system register;


System altered.



6.重新驗證

[oracle@szdb product]$ lsnrctl status
