針對Linux環境

原因：

1. 數據庫實例沒有啟動，檢查數據庫實例運行狀態。

2. 數據庫實例不匹配

環境變量中的ORACLE_SID和啟動后實例是否一致，包括大小寫是否一致?

SQL> startup

ORACLE instance started.

Total System Global Area 717225984 bytes

Fixed Size 2928536 bytes

Variable Size 297795688 bytes

Database Buffers 411041792 bytes

Redo Buffers 5459968 bytes

Database mounted.

Database opened.

SQL> select status, instance_name from v$instance;

STATUS INSTANCE_NAME

OPEN orcl

[oracle@localhost dbs] echo $ORACLE_SID

orcl

以上情況是一樣的。

本地遠程連接配置如下與數據庫環境Database Service是否一致？

本地配置：

ORCLDB =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.230.129)(PORT = 1521))

)

(CONNECT_DATA =

(SERVICE_NAME = orcl)

)

)

數據庫環境Database Service :

查看監聽狀態：

[oracle@localhost bin]$ lsnrctl status

此處不相符！！！在netmgr中 修改為一致，并重啟監聽服務即可！！
