Martin,
 
Thanks for your reply.
 
I was setting port = xxxx instead of mapi_port and that's when I created three binaries to see if I could set the mapi_port in each of the configuration files. Anyhow, now I am able to run 3 instances from one binary on 3 different ports and three different data/log directories.

Hi

You don't need three binaries. You can set the properties on the command
line.
You only have to ensure that each server has a dedicated
(dbfarm/dbname,port)

Window 1:
 mserver5 --dbfarm=`pwd`/monet5/dbfarm --dbname=demo --set mapi_port=50001
# MonetDB server v5.3.0, based on kernel v1.21.0
# Serving database 'demo'
# Compiled for x86_64-redhat-linux-gnu/64bit with 64bit OIDs dynamically
linked
# Copyright (c) 1993-2007 CWI, all rights reserved
# Visit http://monetdb.cwi.nl/ for further information
#warning: please don't forget to set your vault key!
#(see /ufs/mk/monet5//Linux/etc/monetdb5.conf)
# Listening for connection requests on mapi:monetdb://127.0.0.1:50001/

Window2:
mserver5 --dbfarm=`pwd`/monet5/dbfarm --dbname=tst --set mapi_port=50002
# MonetDB server v5.3.0, based on kernel v1.21.0
# Serving database 'tst'
# Compiled for x86_64-redhat-linux-gnu/64bit with 64bit OIDs dynamically
linked
# Copyright (c) 1993-2007 CWI, all rights reserved
# Visit http://monetdb.cwi.nl/ for further information
#warning: please don't forget to set your vault key!
#(see /ufs/mk/monet5//Linux/etc/monetdb5.conf)
# Listening for connection requests on mapi:monetdb://127.0.0.1:50002/

Furthermore, running multiple servers and proper redirection of requests
is handled by the merovingian/monetdb packages.
