EM GRID: How to Change DB Console Http Port

I fixed a failed 11g dbconsole installation using http://www.oracledbasupport.co.uk/standalone-11g-dbconsole-configuration But Dbconsole picked up port 5500 instead of our usual EM port 1159.

How can we change dbconsole port from 5500 to 1159?

Before proceeding take backup of these 3 files
