RAC11g 新增另一个网卡，DG同步

步骤如下：

库1，2节点上配置：

/etc/hosts:

## --- Public IP --- ##

10.12x'x'x.x.113 sfpay-ods-db02

10.12x'x.x'x'x'x.111 sfpay-ods-db01

## --- Virtual IP --- ##

10.12x'x'x'x'x.3.114 sfpay-ods2-vip

10.12x'x'x'x'x'x.3.112 sfpay-ods1-vip

## --- Private IP --- ##

172.16.3.113 sfpay-ods2-priv

172.16.3.111 sfpay-ods1-priv

## ---- Scan IP --- ##

10.120.3.115 db.ods.sfp.com

## --- baoshui DG --- ##

10.120.3.161 sfpay-dg01

#by panbo

10.0.58.136 odsdb-pub-db1

## ---- GuanLan DG IP --- ##

172.23.3.111 ods1-dg

172.23.3.113 ods2-dg

172.23.3.112 ods1-dg-vip

172.23.3.114 ods2-dg-vip

变更前，确认2个节点的会话连接数

3. 在数据库RAC2节点使用root执行

/u01/app/11.2.0.4/grid/bin/srvctl add network -k 2 -S 172.23.0.0/255.255.0.0/em2

/u01/app/11.2.0.4/grid/bin/crsctl start res ora.net2.network

#--2 ,表示新增第二张网卡

/u01/app/11.2.0.4/grid/bin/srvctl add vip -n sfpay-ods-db01 -k 2 -A 172.23.3.112/255.255.0.0/em2

/u01/app/11.2.0.4/grid/bin/srvctl add vip -n sfpay-ods-db02 -k 2 -A 172.23.3.114/255.255.0.0/em2

/u01/app/11.2.0.4/grid/bin/srvctl start vip -i ods1-dg-vip

/u01/app/11.2.0.4/grid/bin/srvctl start vip -i ods2-dg-vip

/u01/app/11.2.0.4/grid/bin/crsctl status res -t

检查默认network的network number,红色字体1，一会儿添加监听会用到：

[grid@rac121 admin]$ srvctl config network

[grid@sfpay-tms-db02 ~]

$ srvctl config network

Network exists: 1/10.120.3.0/255.255.255.0/eth4, type static

Network exists: 2/172.23.0.0/255.255.0.0/eth2, type static # --为新增第二个网卡监听。

查看srvctl添加监听的语法：

[grid@rac121 admin]$ srvctl add listener -h
Adds a listener configuration to the Oracle Clusterware.Usage: srvctl add listener [-l <lsnr_name>] [-s] [-p "[TCP:]<port>[, ...][/IPC:<key>][/NMP:<pipe_name>][/TCPS:<s_port>] [/SDP:<port>]"] [-o <oracle_home>] [-k <net_num>]-l <lsnr_name>           Listener name (default name is LISTENER)  #监听名称-o <oracle_home>         ORACLE_HOME path (default value is CRS_HOME) #grid的HOME-k <net_num>             network number (default number is 1)  #最开始查看的网络号-s                       Skip the checking of ports -p "[TCP:]<port>[, ...][/IPC:<key>][/NMP:<pipe_name>][/TCPS:<s_port>]  [/SDP:<port>]"   Comma separated tcp ports or listener endpoints #要添加的端口号-h                       Print usage

添加监听：名称: LISTENER4 端口号：1524

[grid@rac121 ~]$ srvctl add listener -l LISTENER4 -o $ORACLE_HOME -p 1621 -k 2   # srvctl config network 中 的Network exists  网卡（$srvctl config network）。[grid@rac121 ~]$ srvctl start listener -l LISTENER4

创建完后会在配置文件endpoints_listener.ora和listener.ora中添加记录信息：

[grid@rac121 admin]$ ls
endpoints_listener.ora             listener1206183PM1248.bak  listener.ora             samples     sqlnet1206199AM0038.bak
endpoints_listener.ora.bak.rac121  listener1206199AM0038.bak  listener.ora.bak.rac121  shrept.lst  sqlnet.ora

查看添加的信息：两个文件听红色字体部分

[grid@rac121 admin]$ cat listener.ora
LISTENER4=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER4))))          # line added by Agent

到此完成了监听的添加，再添加静态注册信息，vi listener.ora文件,在里面添加如下内容：

SID_LIST_LISTENER4 = #对应的监听名(SID_LIST =(SID_DESC =(GLOBAL_DBNAME = RACDB)(ORACLE_HOME = /oradata/oracleapp/11.2.0/grid)(SID_NAME = RACDB1) #节点对应的SID))

重启监听即完成静态注册：

-------- 方法一 ----------------

到此就利用srvctl管理工具完成了添加新监听和静态注册的任务。

以下方法二（图形界面）：

了解到以上信息后可能你对当前11.2 RAC中的listener.ora文件中的监听配置信息不再感到奇怪。

我们可以使用netca图形化工具或者srvctl 命令行工具添加监听配置；如果仅仅是手动在listener.ora中添加记录的话是无法被注册为Cluster Ready Service的服务的，将不会被CRS管理。

方法1：

使用netca和netmgr图形化工具，完成添加监听和静态注册的工作。

1) 以Grid Infrastructure GI用户登录任意节点，并运行netca启动图形界面：

su - grid
(grid)$ export DISPLAY=:0
(grid)$ netca

选择LISTENER Configuration

选择ADD

填入监听名字

选择subnet和availabe protocol ，一般默认即可，除非你有多个public network网段

填入端口号

选择NO

选择要启动的监听名，即方才你创建的监听名

之后选择FINISH退出netca 界面，启动netmgr界面，为监听加入静态注册的信息：

su - grid
(grid)$ export DISPLAY=:0
(grid)$ netmgr

点选方才创建的监听器，选择Database Services菜单

填入Global Database Name和本地实例的SID信息，并确认ORACLE HOME Directory(应是Grid Infrastructure的Home目录)正确后点选Save Network Configuration。

之后使用srvctl 或 crsctl 重启该监听即可生效：

[grid@vrh1 admin]$ crsctl status  res ora.MACLEAN_LISTENER.lsnr

以上使用netca和netmgr图形界面工具完成了新监听的添加和静态注册工作。

2. 使用srvctl 工具添加监听并手动加入静态注册信息

检查默认network的network number,红色的数字[grid@vrh1 admin]$ srvctl config network
Network exists: 1/192.168.1.0/255.255.255.0/eth0, type staticsrvctl 添加监听的语法如下[grid@vrh1 admin]$  srvctl add listener -hAdds a listener configuration to the Oracle Clusterware.Usage: srvctl add listener [-l <lsnr_name>] [-s] [-p "[TCP:]<port>[, ...][/IPC:<key>]
[/NMP:<pipe_name>][/TCPS:<s_port>] [/SDP:<port>]"] [-o <oracle_home>] [-k <net_num>]-l <lsnr_name>           Listener name (default name is LISTENER)-o <oracle_home>         ORACLE_HOME path (default value is CRS_HOME)-k <net_num>             network number (default number is 1)-s                       Skip the checking of ports-p "[TCP:]<port>[, ...][/IPC:<key>][/NMP:<pipe_name>][/TCPS:<s_port>] [/SDP:<port>]"
Comma separated tcp ports or listener endpoints-h                       Print usage[grid@vrh1 admin]$  srvctl add listener -l NEW_MACLEAN_LISTENER -o $CRS_HOME -p 1601 -k 1-k 填入方才获得的network number，-p填入端口号，-l填入监听名，-o 填入GI HOME路径[grid@vrh1 admin]$ srvctl start listener -l NEW_MACLEAN_LISTENER

srvctl start listener启动新添加的监听后listener.ora和endpoints_listener.ora会出现新的记录:

[grid@vrh1 admin]$ head -1 listener.ora
NEW_MACLEAN_LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=NEW_MACLEAN_LISTENER))))
# line added by Agent[grid@vrh1 admin]$ head -1 endpoints_listener.ora
NEW_MACLEAN_LISTENER_VRH1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=vrh1-vip)(PORT=1601))
(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.161)(PORT=1601)(IP=FIRST))))
# line added by Agent

以上已经完成了监听的添加，足见使用srvctl管理更为简便。

之后仅需要加入静态注册信息即可,如:

SID_LIST_NEW_MACLEAN_LISTENER =(SID_LIST =(SID_DESC =(GLOBAL_DBNAME = VPROD)(ORACLE_HOME = /g01/11.2.0/grid)(SID_NAME = VPROD1)))

加入如上信息到listener.ora配置文件中(SID_LIST_($LISTENER_NAME)，并重启监听即完成静态注册：

[grid@vrh1 admin]$ srvctl stop listener -l NEW_MACLEAN_LISTENER[grid@vrh1 admin]$ srvctl start listener -l NEW_MACLEAN_LISTENER  [grid@vrh1 admin]$ lsnrctl status NEW_MACLEAN_LISTENERLSNRCTL for Linux: Version 11.2.0.3.0 - Production on 27-NOV-2011 11:21:37Copyright (c) 1991, 2011, Oracle.
