why would one be needing multiple listeners for one database . anyways if u do need multiple listeners then u just have to go to net8 assistant and click the green + button and enter the relevent data. thats it .. simple
Having multiple listeners defenitely enhances the performance.
Comming to the point
creating multiple listeners is simple as rugal said.But Plz note that each lisner listens at a unique port on the same machine.
For the additional listeners u need not change any other configuration except the port numbers.
For ex if u'r first listener listens at port 1521,
the second can listen at 2482,2481....
