DB Server Alias

Hi All, I have the following issue: I need to connect the same instance through 2 IP addresses, i read in this newsgroup that there is a variable in ONCONFIG file called DBSERVERALIASES, this variable permits to set more than one ipaddress/aliasName for the same instance after that I have to configure also sqlhost file to add a new tcp port for the second ipaddress that is associated to the new alias. example: Current ONCONFIG File: # System Configuration SERVERNUM 0 # Unique id corresponding to a OnLineinstance DBSERVERNAME rmtnms02 # Name of default database server DBSERVERALIASES # List of alternate dbservernames DEADLOCK_TIMEOUT 60 # Max time to wait of lock indistributed env. RESIDENT 0 # Forced residency flag (Yes = 1, No = 0) MULTIPROCESSOR 1 # 0 for single-processor, 1 formulti-processor NUMCPUVPS 8 # Number of user (cpu) vps SINGLE_CPU_VP 0 # If non-zero, limit number of cpu vpsto one NOAGE 1 # Process aging Current configuration sqlhost file: ### START OF RMCONF CONFIG rmtnms02 ontlitcp rmtnms02 rmtnms02_tcp ### New configuration: Current ONCONFIG File: # System Configuration SERVERNUM 0 # Unique id corresponding to a OnLineinstance DBSERVERNAME rmtnms02 # Name of default database server DBSERVERALIASES rmtnms02b # List of alternatedbservernames DEADLOCK_TIMEOUT 60 # Max time to wait of lock indistributed env. RESIDENT 0 # Forced residency flag (Yes = 1, No = 0) MULTIPROCESSOR 1 # 0 for single-processor, 1 formulti-processor NUMCPUVPS 8 # Number of user (cpu) vps SINGLE_CPU_VP 0 # If non-zero, limit number of cpu vpsto one NOAGE 1 # Process aging Current configuration sqlhost file: ### START OF RMCONF CONFIG rmtnms02 ontlitcp rmtnms02 rmtnms02_tcp rmtnms02 ontlitcp rmtnms02b rmtnms02b_port ### I have already configured /etc/services for new tcp port (rmtnms02b_port). Is it the correct way to obtain two ipaddres to listen to two different port on the same instance? Thanks in advance, Abanero.
