看上去，一切都ok了，实际上，并没有，我们还SCAN_VIP的属性：
?
[grid@rac1 ~]$ crs_stat -t

ora.scan2.vip ora....ip.type OFFLINE OFFLINE
ora.scan3.vip ora....ip.type OFFLINE OFFLINE
?
[grid@rac1 ~]$ crsctl stat res ora.scan3.vip-p

[grid@rac1 ~]$
?
[grid@rac1 ~]$ crsctl stat resora.scan3.vip
NAME=ora.scan3.vip
TYPE=ora.scan_vip.type

?
所以我们，我们要修改type里的信息。
?
用root用户执行：
[root@rac1 /]#/u01/gridsoft/12.1.0/bin/crsctl modify type ora.scan_vip.type -attr"ATTRIBUTE=SCAN_NAME,DEFAULT_VALUE=cndba-scan.cndba.cn"
[root@rac1 /]#
?
这次就全变了：
[grid@rac1 ~]$ crsctl stat res ora.scan3.vip -p
NAME=ora.scan3.vip
TYPE=ora.scan_vip.type
…
SCAN_NAME=cndba-scan.cndba.cn
…
USR_ORA_VIP=192.168.56.32
VERSION=12.1.0.1.0
?
至此，修改完成。
?
?
?
2.4 启动SCAN
?
用grid用户操作：
?
[grid@rac1 ~]$ srvctl start scan
[grid@rac1 ~]$ srvctl start scan_listener
?
?
?
2.5 验证
?
[grid@rac2 ~]$ srvctl config scan
