修改SCAN IP

1，修改/etc/hosts

2，使用grid用户停止scanIP
 $GRID_HOME/bin/srvctl stop scan_listener
 $GRID_HOME/bin/srvctl stop scan

3，使用root用户修改scan
export ORACLE_HOME=/u01/app/11.2.0/grid
export PATH=$PATH:$ORACLE_HOME/bin
srvctl modify scan -n scan_name 
检查参数文件remote_listener参数
SQL> show parameter remote_listener

### For 11.2.0.1 only, if you intend to change SCAN name, due to bug 9603829, execute the following:
 $GRID_HOME/bin/crsctl modify type ora.scan_vip.type -attr "ATTRIBUTE=SCAN_NAME,DEFAULT_VALUE=<new SCAN name>"
### Example:
 $GRID_HOME/bin/crsctl modify type ora.scan_vip.type -attr "ATTRIBUTE=SCAN_NAME,DEFAULT_VALUE=pay-scan.us.oracle.com"

4，使用grid用户启动资源
$ srvctl modify scan_listener -u
$ srvctl start scan_listener

5，验证
$ srvctl config scan 
$ srvctl config scan_listener

srvctl status scan
srvctl status scan_listener
