Oracle 12.1 RAC 系列 – 配置第二個網絡和相應的SCAN2

xfxyxh 2019-07-28

展開全文

在配置ADG或者使用oracle 的集群管理應用的HA時（比如OGG），我們可能希望使用不同的網絡，以避免ADG傳輸日志等對主生產網絡的造成影響。
從11.2開始，我們可以使用crs管理多個網絡資源（缺省只有network1），但是SCAN只能在多個網絡中的一個上活動（缺省是network1，后續(xù)可以指定到不同網絡上）。
然后，我們通常會配置專門為ADG傳輸日志的network2網絡，但是在配置連接串時，只能使用vip（因為SCAN通常給主生產上的network1使用）。
.
從12.1開始，我們可以配置多個網絡上的多個SCAN，比如我們配置ADG時，在network2上配置SCAN2。
具體配置如下：
–檢查網卡接口對應的IP地址：

[root@rac1 ~]# ifconfig | egrep 'eth0' -A 1 | grep 'inet ' | cut -d : -f2 | cut -d ' ' -f1

192.168.56.61

192.168.56.63

[root@rac1 ~]# ifconfig | egrep 'eth2' -A 1 | grep 'inet ' | cut -d : -f2 | cut -d ' ' -f1

192.168.209.61

[root@rac1 ~]#

[root@rac2 ~]# ifconfig | egrep 'eth0' -A 1 | grep 'inet ' | cut -d : -f2 | cut -d ' ' -f1

192.168.56.62

192.168.56.64

192.168.56.65

[root@rac2 ~]# ifconfig | egrep 'eth2' -A 1 | grep 'inet ' | cut -d : -f2 | cut -d ' ' -f1

192.168.209.62

[root@rac2 ~]#

–添加新的public網絡

[grid@rac1 ~]$ oifcfg getif

eth0 192.168.56.0 global public

eth1 192.168.60.0 global cluster_interconnect

[grid@rac1 ~]$

[grid@rac1 ~]$ oifcfg setif -global eth2/192.168.209.0:public

[grid@rac1 ~]$ oifcfg getif

eth0 192.168.56.0 global public

eth1 192.168.60.0 global cluster_interconnect

eth2 192.168.209.0 global public

[grid@rac1 ~]$

–檢查網絡定義，缺省只有一個網絡定義：network1

[grid@rac1 ~]$ srvctl config network

Network 1 exists

Subnet IPv4: 192.168.56.0/255.255.255.0/eth0, static

Subnet IPv6:

Ping Targets:

Network is enabled

Network is individually enabled on nodes:

Network is individually disabled on nodes:

[grid@rac1 ~]$

–添加新的網絡集群資源（a new network cluster resource）

[root@rac1 ~]# ipcalc -bnm 192.168.209.61 255.255.255.0

NETMASK=255.255.255.0

BROADCAST=192.168.209.255

NETWORK=192.168.209.0

[root@rac1 ~]#

[root@rac1 ~]# srvctl add network -netnum 2 -subnet 192.168.209.0/255.255.255.0/eth2

[root@rac1 ~]#

[root@rac1 ~]# srvctl config network

Network 1 exists

Subnet IPv4: 192.168.56.0/255.255.255.0/eth0, static

Subnet IPv6:

Ping Targets:

Network is enabled

Network is individually enabled on nodes:

Network is individually disabled on nodes:

Network 2 exists

Subnet IPv4: 192.168.209.0/255.255.255.0/eth2, static

Subnet IPv6:

Network is enabled

[root@rac1 ~]#

這時集群的網絡資源中已經配置了兩個網絡（包括新增加的網絡），如果使用“crsctl status res -t”查看，可以看到：

[root@rac1 ~]# crsctl status res -t |grep -A 2 network

–添加vip

[root@rac1 ~]# srvctl add vip -node rac1 -netnum 2 -address rac1-adg-vip/255.255.255.0/eth2

[root@rac1 ~]# srvctl add vip -node rac2 -netnum 2 -address rac2-adg-vip/255.255.255.0/eth2

[root@rac1 ~]# srvctl config vip -n rac1
