ccm7.2 or later_router 5412/tcp # Rational Synergy router port
The first column is the service name, which must be ccm7.2 or later_router. The second column starts with the port number. You can use any deallocated port number, but use 5412 if you can. This TCP port number is reserved for Rational by the Internet Assigned Number Authority (IANA).
Make a note of the service name and port number that you chose. You must supply that information to ccm_install. By default, ccm_install uses the service name ccm7.2 or later_router, and the reserved port number 5412.
Also, you might want to reserve port numbers for the CCM server (ccm_server) and engine startup daemon (esd). Use of esd is optional.
If you are running NIS, add the appropriate entries to your master services map. If you do not use NIS, add these entries to the /etc/services file on each relevant computer.
The /etc/services entry for a particular database server looks like the following entry:
server_name_host_name port_number/tcp
Choose any unused value for port_number.
For example, if your are using an Informix database and are planning to create an Informix database server on the computer olga, create a services entry of the form:
olga_olga 5432/tcp
On some systems, depending on how the system and the send mail configuration are set up, the host_name portion of this entry might need to be the long name (fully qualified domain name):
olga_olga.cwi.com 5432/tcp
