change data guard ip
let say currently data guard server is at a.b.c.d (ip address).
so we create a new connection to the server. a.b.e.d.
eg: 1.2.3.4 (current ip)
1.2.5.4 (new ip)
other than to change tnsnames.ora and data guard setting (DGMGRL > edit database "drsmp" set property 'LocalListenerAddress'='(ADDRESS=(PROTOCOL=tcp)(HOST=), what else should i do?
and what could cause "ora-16737 the redo transport...." it related to tns,right? and if tnsping a success?
