'when do we get PORTMAP procedure GETADDR and GETPORT
Can someone comment on how and at which level in portmap program version is decided. Actually in 2 different environments I am getting different Procedure and program version. in case 1 : I am getting Program version as 2 and procedure GETPORT in case 2 : I am getting Program version as 4 and procedure GETADDR.
How can I ensure that in every case GETPORT is called not GETADDR.

The small confusion comes from the fact that you use probably the same client that talk to two 'different' services to portmap, exposed as program with #100000, version 2 and rpcbind service, exposed as program #100000, version 4. To match the correct service the combination of program and the version is used. Thus, bough can share the same TPC/UDP port, but provide different services.
portmap
Returns TCP/UDP port number of registered program, like:
GETPORT {'program': '100003', 'version': 4} => 2049
rpcbind
Returns the universal addresses of registered program, like:
GETADDR {'program': '100003', 'version': 4, 'netid': 'tcp'} => 0.0.0.0.8.1
Typical rpcbind service support the portmap protocol as well.
