1、啟動oracle的步驟

1、啟動oracle的步驟

Linux下啟動oracle分為以下兩步:

  • 1.1、啟動lsnrctl監聽。
  • 1.2、啟動資料庫例項。

2、啟動oracle監聽

首先登陸伺服器,切換到oracle使用者。

[admin@dataserver ~]$ su - oracle
密碼:
[oracle@dataserver ~]

這裡寫圖片描述

接下來,檢查oracle監聽器執行狀態,通過lsnrctl status命令檢視。

[oracle@dataserver ~]$ lsnrctl status

  TNS-00511: No listener

[oracle@dataserver

上述反饋的結果即為oracle監聽沒有啟動,下面執行啟動監聽,通過命令lsnrctl start,結果如下:

[oracle@dataserver ~]$ lsnrctl start

上述反饋為監聽啟動失敗,是因為其監聽的IP30.85.227.24,並非伺服器的IP,所以需要調整這個IP為伺服器當前的IP。

在oracle使用者下,進入目錄/u01/app/oracle/product/11.2.0/dbhome_1/network/admin,修改listener.ora檔案。注意這個目錄因具體伺服器而異。 
這裡寫圖片描述

listener.ora檔案開啟,內容如下,調整其中的HOST IP即可。

# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = ORCL)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
      (SID_NAME = ORCL)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 30.85.227.28)(PORT = 1521))
    )
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 30.85.227.23)(PORT = 1521))
    )

  )

ADR_BASE_LISTENER = /u01/app/oracle

調整完監聽IP後,重啟監聽器,執行lsnrctl start,

[oracle@dataserver admin]$ lsnrctl start

至此,oracle監聽器啟動成功!

3、啟動oracle例項

以system使用者身份登陸oracle

[oracle@dataserver admin]$ sqlplus /nolog

SQL*Plus: Release 11.2.0.1.0 Production on 星期五 415 15:23:04 2016

Copyright (c) 1982, 2009, Oracle.  All rights reserved.

SQL> conn as sysdba
Enter user-name: system
En

然後啟動例項,通過startup命令:

SQL> startup
ORACLE instance started.

Total System Global Area 4.0620E+10 bytes
Fixed Size          2216024 bytes
Variable Size        2.3354E+10 bytes
Database Buffers     1.7180E+10 bytes
Redo Buffers           84054016 bytes
Database mounted.
Database opened.
SQL>8

4、關閉oracle例項

通過shutdown命令關閉oracle例項。

SQL> shutdown
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL>
