srvctl modify scan

Modifies the number of SCAN VIPs to match the number of IP addresses returned by looking up the scan_name you specify in DNS. You use this command when DNS was modified to add, change, or remove IP addresses, and now you must adjust the Oracle Clusterware resource configuration to match.


This command is only available with Oracle Clusterware.

Syntax and Parameters

Use the srvctl modify scan command with the following syntax:

srvctl modify scan -scanname scan_name 

Table A-89 srvctl modify scan Parameters

Parameter Description
-scanname scan_name

Identifies the SCAN name that resolves to the SCAN VIPs that you want to modify.

Note: You can modify this attribute using Online Resource Attribute Modification.


Assume your system currently has a SCAN named scan_name1, and it resolves to a single IP address in DNS. If you modify the SCAN scan_name1 in DNS to resolve to three IP addresses, then use the following command to create the additional SCAN VIP resources:

$ srvctl modify scan -scanname scan_name1
