oraclelinux監聽配置
① linux系統下想圖形配置oracle監聽時，輸入netca不行，什麼原因
明顯是display沒有設置：DISPLAY environment variable not set!
root用戶，在同一和命令窗口下，命令：（一行一個）
export DISPLAY=:0.0
xhost +
然後在這個窗口下切換oracle用戶，執行netca
② oracle linux配置監聽時報錯埠佔用
前提回現
修改了主機名，由hyldb修改為hyl。
問題現象
配置監聽，警告提示，如下所示：
解決方法
1、檢查1521埠
[root@hyl ~]# netstat -a
--查看埠佔用情況，查明1521埠並未被佔用

2、檢查hosts
[root@hyl ~]# vi /etc/hosts
修改前：
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 hyldb localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.56.101 hyl
~
~
~
--由於修改了主機名（hyldb修改為hyl），將之前配置中hyldb內容刪除
修改為：
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.56.101 hyl
~
~
~
~
3、檢查network
# vi /etc/sysconfig/network
--確認添加了如下信息
NETWORKING=yes
HOSTNAME=hyl
4、檢查ipv6是否關閉
查看ipv6狀態，查看其是否被關閉
[root@hyl ~]# lsmod |grep ipv6
ipv6 435105 17 cnic
xfrm_nalgo 43333 1 ipv6
[plain] view plain 在CODE上查看代碼片派生到我的代碼片
補充：關閉ipv6方法
1） # vim /etc/modprobe.conf
在其中加入下面這一行，
install ipv6 /bin/true
保存並退出。
2）# vim /etc/sysconfig/network
在其中加入下面配置項：
NETWORKING_IPV6=no
IPV6INIT=no
重啟後查詢：
[root@hyl ~]# lsmod |grep ipv6
--沒有顯示ipv6相關信息，表示ipv6已經關閉
5、重啟系統後，查看hostname
[root@hyl ~]# hostname
--查詢主機名
hyl
6、再次執行netca
配置監聽、dbca建庫成功。
③ 如何在linux suse中安裝Oracle 11g創建監聽
在linux suse中安裝Oracle 11g創建監聽的步驟：
在本地oracle用戶模式下 oracle@linux-udly:~> netca
接下來按圖一直點擊NEXT
此處可以修改oracle監聽器的埠號
④ linux操作系統下，如何啟動oracle服務與監聽命令
1、切換到oracle用戶x0dx0asu - oraclex0dx0a2、startdb.sh命令腳本x0dx0a#!/bin/shx0dx0alsnrctl startx0dx0asqlplus "/as sysdba" << 、netstat -ntlp或ps -ef |grep ora檢查x0dx0a4、shutdb.sh命令腳本x0dx0a#!/bin/bashx0dx0alsnrctl stopx0dx0asqlplus "/as sysdba" << EOFx0dx0ashutdown immediatex0dx0aEOF
⑤ linux操作系統下oracle資料庫如何配置監聽
1. 修改監聽器配置文件
Linux下Oracle監聽器配置文件在：$ ORACLE_HOME/network/admin/listerer.ora, 如：
/bank/oracle/oracle10g/proct/10.2.0/network/admin/listener.ora
修改並配置要監聽SID的相關信息，如：
#listener.ora Network Configuration File: /bank/oracle/oracle10g/proct/10.2.0/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /bank/oracle/oracle10g/proct/10.2.0)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL DBNAME = bkserver)
(SID_NAME = bkserver)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.7.13.242)(PORT = 1521))
)
)
2. 啟動監聽器
(1). 切換至oracle安裝用戶（一般為oracle）
su - oracle
(2). 啟動監聽器
lsnrctl start
另：停止監聽器
lsnrctl stop
3. 測試監聽器是否運行正常
在客戶端修改tnsnames.ora配置文件就訪問Oracle資料庫，如：
BKSERVER =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.7.13.242)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = BKSERVER)
)
)
通過命令tnsping測試是否能訪問到監聽器，如：
M:\>tnsping bkserver
TNS Ping Utility for 32-bit Windows: Version 10.2.0.1.0 - Proction on 12-8月 -
2010 17:11:04
Copyright (c) 1997, 2005, Oracle. All rights reserved.
已使用的參數文件:
D:\oracle\proct\10.2.0\client_1\network\admin\sqlnet.ora
已使用 TNSNAMES 適配器來解析別名
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)
(HOST = 10.7.13.242)(PORT = 1521))) (CONNECT_DATA = (SERVER = DEDICATED) (SERVIC
E_NAME = BKSERVER)))
OK (20 毫秒)
注意： 監聽器是否能被tnsping通跟資料庫的開啟/關閉無關，所以就算可以tnsping通監聽器但未必能連接到資料庫，這時請檢查listener.ora文件配置信息是否正確，還有資料庫是否已經被開啟。
