If you are running Rational® Synergy
engines and the database server on the same computer, you do not need
to set up remote engine hosts. If you plan to run engine processes
on computers other than the database server, you must set up remote
engine hosts.
Procedure
- Define the engine hosts in the following network system
files:
- hosts (or DNS)
- hosts.equiv (or .rhosts)
Ensure that your host IP addresses are unique and consistent,
and check access to each host.
- Run ccm_install -l on the engine hosts.
- If you intend to use Rational Change,
you might need to install the Engine Startup Daemon (ESD) or rexec daemons.
See the Configuring the engine startup daemon for UNIX topic in the Rational Change information
center.
- For VPN clients, add the VPN IP address
to /etc/hosts or the DNS equivalent. You can
give the VPN IP address any name as long as it has a name. An example
of the type of entry you can make in your hosts
file is:
192.168.45.10 vpnclient1
192.168.45.11 vpnclient2
192.168.45.12 vpnclient3
Alternatively, instruct your DNS server
to construct host names spontaneously for reverse lookups of IP addresses
in the subnet used for your VPN.
- By default, Linux does
not interpret the plus sign (+) in either the .rhosts file
or the /etc/hosts.equiv file. To permit the use
of +, add the promiscuous argument to the end of
the .rhosts auth line in /etc/pam.d/rsh.
- For Linux users,
set permissions in the /etc/hosts.allow file.
Using the setting ALL:ALL, which allows any client
to use any service, is optimal. However, this setting might raise
network security concerns.
- If the database server and
the installation computers are not the same:
- Run the object registrar on your database server.
- Run ccm_install -l on the engine hosts.
- If you plan to run web mode sessions, run ccm_server on
each computer that will run the sessions.
