一、Oracle監聽

操作聲明：登錄服務器，切換到oracle用戶，或者以oracle用戶登錄
#切換oracle用戶
[root@localhost ~]$ su - oracle
密碼：
[oracle@localhost ~]$

1.1. 查看Oracle監聽運行狀態

[oracle@localhost ~]$ lsnrctl status

從圖中可以看到oracle監聽沒有運行

1.2. 啟動Oracle監聽

[oracle@localhost ~]$ lsnrctl start

再次查看Oracle監聽運行狀態

[oracle@localhost ~]$ lsnrctl status

從圖中可以看到oracle監聽已經運行

1.3. 關閉監聽器

二、Oracle 服務

2.1. 以SYS用戶身份登錄Oracle

[oracle@localhost ~]$ sqlplus /nologSQL*Plus: Release 11.2.0.4.0 Production on Sat May 16 15:43:46 2020Copyright (c) 1982, 2013, Oracle. All rights reserved.SQL> conn /as sysdba Connected to an idle instance.

2.2. 切換用戶至sys

切換用戶：
CONN 用戶名/密碼 [AS SYSDBA]，如果是sys用戶一定要寫上AS　SYSDBA

sqlplus /nolog conn /as sysdba

2.3. 啟動Oracle實例

SQL> startup ORACLE instance started.Total System Global Area 8551575552 bytes Fixed Size 2270360 bytes Variable Size 4244638568 bytes Database Buffers 4294967296 bytes Redo Buffers 9699328 bytes Database mounted. Database opened.

2.4. 停止Oeacle實例運行

SQL> shutdown Database closed. Database dismounted. ORACLE instance shut down. SQL> quit Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production With the Partitioning, OLAP, Data Mining and Real Application Testing options

操作日志如下；
