备份:2台主机:
私有网络配置不仅仅存在ocr中,还存在gpnp profile中,所以首先需要备份profile.xml:
[grid@host01 peer]$ pwd
/u01/11.2.0/grid/gpnp/host01/profiles/peer
[grid@host01 peer]$ ls
pending.xml profile.old profile_orig.xml profile.xml
[grid@host01 peer]$ cp profile.xml profile.xml.bak
[root@host02 ~]#
[root@host02 ~]# cd /u01/11.2.0/grid/gpnp/host02/profiles/peer/
[root@host02 peer]# ls
profile_orig.xml profile.xml
[root@host02 peer]# cp profile.xml profile.xml.bak
Ocr备份:
[root@host01 ~]# /u01/11.2.0/grid/bin/ocrconfig -manualbackup

eth4 172.16.0.0 global public
6.修改VIP--停止数据库和监听
srvctl stop vip -n host01
srvctl stop vip -n host02
#root用户修改:
srvctl modify nodeapps -n host01 -A 172.16.0.136/255.255.255.0/eth4
srvctl modify nodeapps -n host02 -A 172.16.0.139/255.255.255.0/eth4
[root@host01 ~]# /u01/11.2.0/grid/bin/srvctl config vip -n host01
VIP exists: /172.16.0.136/172.16.0.136/172.16.0.0/255.255.255.0/eth4, hosting node host01

--修改:
alter system set local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=172.16.0.136)(PORT=1521))' sid='orcl1';
alter system set local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=172.16.0.139)(PORT=1521))' sid='orcl2';
7.修改SCAN VIP
srvctl stop scan_listener
srvctl stop scan
srvctl status scan_listener
srvctl status scan
#root
/u01/11.2.0/grid/bin/srvctl modify scan -n scan
/u01/11.2.0/grid/bin/srvctl config scan
SCAN name: scan, Network: 1/172.16.0.0/255.255.255.0/eth4
