Modifying SCAN Configuration in Oracle 11g Release 2 RAC
Rename SCAN
The original name was "ol6-112-scan" and I want to rename it to "ol6-112-scan2". Check the new name is configured in the DNS.
$ nslookup ol6-112-scan2 Server: 192.168.0.4 Address: 192.168.0.4#53 Name: ol6-112-scan2.localdomain Address: 192.168.0.117 Name: ol6-112-scan2.localdomain Address: 192.168.0.116 Name: ol6-112-scan2.localdomain Address: 192.168.0.115 $
Display the current configuration using the following command as the oracle/grid user.
$ export GRID_HOME=/u01/app/11.2.0.3/grid $ $GRID_HOME/bin/srvctl config scan SCAN name: ol6-112-scan, Network: 1/192.168.0.0/255.255.255.0/eth0 SCAN VIP name: scan1, IP: /ol6-112-scan/192.168.0.115 SCAN VIP name: scan2, IP: /ol6-112-scan/192.168.0.116 SCAN VIP name: scan3, IP: /ol6-112-scan/192.168.0.117 $
Turn off the SCAN and SCAN listeners using the following commands as the oracle/grid user.
$ export GRID_HOME=/u01/app/11.2.0.3/grid $ $GRID_HOME/bin/srvctl stop scan_listener $ $GRID_HOME/bin/srvctl stop scan
Modify the SCAN name using the following commands as the root user.
# export GRID_HOME=/u01/app/11.2.0.3/grid # $GRID_HOME/bin/srvctl modify scan -n ol6-112-scan2 # $GRID_HOME/bin/crsctl modify type ora.scan_vip.type -attr "ATTRIBUTE=SCAN_NAME,DEFAULT_VALUE=ol6-112-scan2"
Turn on the SCAN and SCAN listeners again using the following commands as the oracle/grid user.
$ $GRID_HOME/bin/srvctl modify scan_listener -u $ $GRID_HOME/bin/srvctl start scan_listener
Display the changed configuration.
$ $GRID_HOME/bin/srvctl config scan SCAN name: ol6-112-scan2, Network: 1/192.168.0.0/255.255.255.0/eth0 SCAN VIP name: scan1, IP: /ol6-112-scan2/192.168.0.115 SCAN VIP name: scan2, IP: /ol6-112-scan2/192.168.0.116 SCAN VIP name: scan3, IP: /ol6-112-scan2/192.168.0.117 $
