Oracle Database Discussions

Hi,

I am confused abort database ports. Are database ports the same as the listener ports?

I have 15 databases in our windows 2003 server. Combination of 9i,10g,11g

It has 3 kinds of listeners for 9i, 10g, and 11g.

5 9i database uses listener9i with port 1521 ===> does this mean their database port is 1521?
5 10g database uses listener10g with port 1522 ===> does this mean their database port is 1522?
5 11g database uses listener11g with port 1523 ===> does this mean their database port is 1523?

If I merge all 3 listeners into the 11g listener with port 1523. Does this mean all my 15 databases has same port which is 1523?

Can it be possible that 1 database can be enrolled in 3 listeners, so that it can have 3 different ports?

So it follows that database port is not unigue to each database?



Thanks
