Your network administrator informs you that the Internet service provider is being changed
in a month’s time in conjunction with a data center move. You are asked to plan for the
changes required in the Oracle Grid Infrastructure, which is set up to use GNS. The IP
addresses and subnets of the public network are to change. Which two must be done in the
Oracle Grid Infrastructure network setup to accommodate this change using the
command-line Interfaces available?
A.
The interconnect must be reconfigured by using oifcfg, crsctl, and ifconfig.
B.
The SCAN VIPs and node VIPs must be reconfigured by using oifcfg.
C.
The SCAN VIPs and SCAN listener resources must be removed and added to obtain the
new SCAN IP addresses from DHCP.
D.
The SCAN VIPs and node VIPs must be reconfigured using srvctl.
E.
The Interconnect must be reconfigured by using srvctl.
I think the answers are not accurate, generally for change the public addresses it isn’t necessary to change interconnect addresses.
since you want to use GNS, you need to add static address for GNS-VIP and as the public address has been changed we need to change in DNS and the public addresses.
A: is not correct because Interconnect won’t need to be changed at all.
B: is not correct because with oifcfg we couldn’t change SCAN-VIP and NODE-VIP.
C: is not correct because it’s not shortest way to change SCAN VIPs. we could command as below:
$ srvctl modify scan –n mas-scan
$ srvctl modify scan_listener -u
D: is correct answer.
E: is not correct because Interconnect dose not need to change nor SRVCTL tools could be used to change that.
