Considerations
- You cannot use the
ALTER SYSTEM SETstatement to modify this parameter. - When you start an OBServer node, you can specify the IP address by using the
-Ior--local_ipoption. - We recommend that you do not specify both the
local_ipanddevnameparameters. If you specify both, the value oflocal_iptakes precedence. - You can specify the IP address in the
local_ip=xxx.xxx.xxx.xxxformat by using the-ooption. We recommend that you use the-Ior--local_ipoption to specify the IP address. If you specify the IP address by using both the-Ior--local_ipand-ooptions, the IP address specified by using the-ooption takes precedence.
Examples
Start an OBServer node by specifying an IP address.
