修改ORACLE 19C RAC公共網(wǎng)卡為其他網(wǎng)卡
比如由 enp49s0f0 修改為 ens4f0
1.集群在所有節(jié)點正常
crsctl stat res -t
2.刪除以前的網(wǎng)卡，增加新的網(wǎng)卡
% $
CRS_HOME/bin/oifcfg/oifcfg delif -global <if_name>[/<subnet>]
% $
CRS_HOME/bin/oifcfg/oifcfg setif -global <if_name>/<subnet>:public
For example:
% $CRS_HOME/bin/oifcfg delif -global enp49s0f0/192.168.2.0
% $CRS_HOME/bin/oifcfg setif -global ens4f0/192.168.2.0:public
確認修改：
[grid@easdb2 ~]$ oifcfg getif
ens4f1 10.0.0.0 global cluster_interconnect,asm
ens4f0 192.168.2.0 global public
3.在操作系統(tǒng)上修改網(wǎng)卡IP
停用以前網(wǎng)卡
啟用新網(wǎng)卡IP
nmcli con
[root@easdb2 ~]# nmcli con
NAME UUID TYPE DEVICE
ens4f0
11d1d159-e438-bc38-bba2-411145f244b4 ethernet ens4f0

4.修改對應(yīng)VIP
先確定一下當前VIP 在哪個網(wǎng)卡
srvctl config nodeapps -a
修改新VIP到新的網(wǎng)卡
srvctl modify nodeapps -n <nodename>1 -A <nodename>1-nvip/255.255.255.0/<if_name>
for example:
su - root

/u01/app/19.3.0/grid/bin/srvctl modify nodeapps -n easdb1 -A?192.168.2.36/255.255.255.0/ens4f0

/u01/app/19.3.0/grid/bin/srvctl modify nodeapps -n easdb2 -A?192.168.2.37/255.255.255.0/ens4f0
確認修改：
srvctl config nodeapps -a
[grid@easdb1 ~]$ srvctl config nodeapps -a
