SUSE 11 + Oracle 11g ADG修改主庫IP全流程
阿新 • • 發佈：2018-05-17
Oracle 11G ADG 修改IP
一、描述
數據庫版本11g,單實例ADG.
操作系統版本為SUSE 11 SP3.
主庫IP：192.168.1.11
備庫IP：192.168.1.12
二、需求
主庫需要修改IP地址，保證ADG環境正常運行。
主庫IP 改為：192.168.1.10，備庫IP不變。
三、操作步驟
1、檢查主備庫當前是否正常運行
oracle@mmpt-SRJ:~> dgmgrl /
DGMGRL for Linux: Version 11.2.0.1.0 - 64bit Production

Configuration - dg_broker
Protection Mode: MaxPerformance
Databases:
mmpt - Primary database
mmptdg - Physical standby database
Fast-Start Failover: DISABLED
Configuration Status:
SUCCESS
DGMGRL>
2、關閉主、備庫
lsnrctl stop listener
shutdown immediate;
3、修改操作系統IP地址
mmpt-SRJ:/etc/sysconfig/network # ls
config dhcp if-down.d if-up.d ifcfg-eth0 ifcfg-lo ifcfg.template ifroute-lo providers scripts
mmpt-SRJ:/etc/sysconfig/network # vi ifcfg-eth0
BOOTPROTO=‘static‘
BROADCAST=‘‘
ETHTOOL_OPTIONS=‘‘
IPADDR=‘192.168.1.10/24‘
MTU=‘‘
NAME=‘82540EM Gigabit Ethernet Controller‘
NETWORK=‘‘
REMOTE_IPADDR=‘‘
STARTMODE=‘auto‘
USERCONTROL=‘no‘

mmpt-SRJ:/etc/sysconfig/network # /etc/init.d/network restart

.............重新使用新IP地址連接...................
4、主庫修改監聽文件listener.ora
oracle@mmpt-SRJ:/fantlam/oracle/app/oracle/product/11.2.0/dbhome_1/network/admin> vi listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = mmpt)
(ORACLE_HOME = /fantlam/oracle/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = mmpt)
)
)
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.10)(PORT = 1521))
4、主庫修改監聽文件tnsnames.ora
oracle@mmpt-SRJ:/fantlam/oracle/app/oracle/product/11.2.0/dbhome_1/network/admin> vi tnsnames.ora
# tnsnames.ora Network Configuration File: /fantlam/oracle/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
MMPT =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.10)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = mmpt)
)
)
mmptdg =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.12)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = mmptdg)
)
)
4、主庫修改hosts文件
mmpt-SRJ:~ # vi /etc/hosts
#
# hosts This file describes a number of hostname-to-address
# mappings for the TCP/IP subsystem. It is mostly
# used at boot time, when no name servers are running.
# On small systems, this file can be used instead of a
# "named" name server.
# Syntax:
#
# IP-Address Full-Qualified-Hostname Short-Hostname
#
127.0.0.1 localhost
# special IPv6 addresses
::1 localhost ipv6-localhost ipv6-loopback
fe00::0 ipv6-localnet
ff00::0 ipv6-mcastprefix
ff02::1 ipv6-allnodes
ff02::2 ipv6-allrouters
ff02::3 ipv6-allhosts
#192.168.1.11 suse11.site suse11
192.168.1.10 mmpt-SRJ mmpt-SRJ
192.168.1.12 mmpt-SRJ-dg mmpt-SRJ-dg
5、備庫不需要修改listener.ora
oracle@mmpt-SRJ-dg:/fantlam/oracle/app/oracle/product/11.2.0/dbhome_1/network/admin> cat listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = mmptdg)
(ORACLE_HOME = /fantlam/oracle/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = mmptdg)
)
)
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.12)(PORT = 1521))
)
6、備庫修改監聽文件tnsnames.ora
oracle@mmpt-SRJ-dg:/fantlam/oracle/app/oracle/product/11.2.0/dbhome_1/network/admin> vi tnsnames.ora
# tnsnames.ora Network Configuration File: /fantlam/oracle/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
MMPT =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.10)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = mmpt)
)
)
mmptdg =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.12)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = mmpt-SRJ-dg)
)
)
"tnsnames.ora" 21L, 529C written
7、備庫修改hosts文件
mmpt-SRJ-dg:~ # vi /etc/hosts
#
# hosts This file describes a number of hostname-to-address
# mappings for the TCP/IP subsystem. It is mostly
# used at boot time, when no name servers are running.
# On small systems, this file can be used instead of a
# "named" name server.
# Syntax:
#
# IP-Address Full-Qualified-Hostname Short-Hostname
#
127.0.0.1 localhost
# special IPv6 addresses
::1 localhost ipv6-localhost ipv6-loopback
fe00::0 ipv6-localnet
ff00::0 ipv6-mcastprefix
ff02::1 ipv6-allnodes
ff02::2 ipv6-allrouters
ff02::3 ipv6-allhosts
192.168.1.12 mmpt-SRJ-dg mmpt-SRJ-dg
192.168.1.10 mmpt-SRJ mmpt-SRJ
~
"/etc/hosts" 24L, 721C written
8、啟動主備庫監聽，測試
lsnrctl start listener
tnsping mmpt
tnsping mmpt-dg
輸出如下：
oracle@mmpt-SRJ:~> lsnrctl start
