#ORACLE
$ srvctl stop database -d db_name操作前最好先备份两个节点的profile.xml文件
#GRID
$ cd $GRID_HOME/gpnp/hostname/profiles/peer/
$ cp -p profile.xml profile.xml.bk用grid用户在一个节点上关闭监听
#GRID
$ srvctl stop listener -n hostname1
$ srvctl stop listener -n hostname2
$ srvctl stop scan_listener用grid用户在一节点关闭vip和scan vip
#GRID
$ srvctl stop vip -n hostname1
$ srvctl stop vip -n hostname2
$ srvctl stop scan用grid用户在一节点更改私公网和网通讯接口
#GRID
$ oifcfg getif --查看当前公网和网通讯接口$ oifcfg getifg
team1 20.8.91.0 global public
team2 16.0.100.0 global cluster_interconnect,asm#GRID
$ oifcfg setif -global 私有网卡名/新私有网段:cluster_interconnect,asm$ oifcfg setif -global team1/20.8.91.0 :cluster_interconnect,asm
$ oifcfg setif -global team2 /16.0.100.0 :publicgrid用户登陆一节点配置新的priv子网
#GRID
$ srvctl config listener -asmlistener
$ srvctl config asm
--查看原ASMLISTENER添加新的ASMLISTENER:
#GRID
$ srvctl add listener -asmlistener -l ASMNET1LSNR2_ASM -subnet 20.8.91.0 删除旧的ASMLISTENER:
#GRID
$ lsnrctl stop ASMNET1LSNR_ASM
$ srvctl update listener -listener ASMNET1LSNR_ASM -asm -remove -forceroot用户配置asmnetwork
$ROOT
# srvctl config asmnetwork
# srvctl stop asmnetwork
# srvctl remove asmnetwork -netnum 1
# srvctl add asmnetwork -netnum 1 -subnet 20.8.91.0 修改后关闭集群自启动并关闭集群
$ROOT
# crsctl disable crs
# crsctl stop cluster -all重启集群后root用户修改VIP资源为目标IP
$ROOT
# srvctl modify nodeapps -n hostname1 -A hostname1-vip/255.255.255.0/网卡
# srvctl modify nodeapps -n hostname2 -A hostname2-vip/255.255.255.0/网卡
验证是否修改成功
# srvctl config vip -n hostname1
# srvctl config vip -n hostname2
修改scan IP
$ROOT
# srvctl modify scan -n scan-IP名#srvctl modify scan -n yysd-scan#GRID
$ srvctl modify scan_listener -u
$ srvctl config scan
$ srvctl config scan_listener用户grid登陆任一节点启动vip资源和scan vip资源
#GRID
$ srvctl start vip -n hostname1
$ srvctl start vip -n hostname2
$ srvctl start scan
$ srvctl start listener -n hostname1
$ srvctl start listener -n hostname2
$ srvctl start scan_listener
