Machines running Rational® Synergy daemons (router, object registrar, and engine startup daemon) must be reachable by all other Rational Synergy processes. Machines running database servers must be reachable from Rational Synergy engine processes. Machines running engines, routers, object registrars, and ESDs must be reachable from Rational Synergy interface processes.
About this task
For machine A to be reachable from machine B:
- Machine A must return a host name that can be resolved by machine B.
OR
- The host name of machine A must map (on machine A) to an IP address that can be used to connect to machine B (possibly by resolving a different name).
If your site starts Rational Synergy sessions that must cross a firewall to access Rational Synergy servers, the IP address or host name might be valid. You might not be able to connect because the engine, router, or object registrar host name might not be resolvable on the client machine if the client is behind a firewall. Instead, the IP address or host name must be accessible to the proxy server. For more information, in the Rational Synergy Information center, go to .
Procedure
To allow machines to be reachable through consistent names:
- Verify that each machine that is used for daemons, database servers, and engines has a single, unique name recognized throughout your network. Also, ensure that either a simple or fully qualified name is used consistently.
If the database server machines do not have recognized names, set the servers names to their IP addresses to make them recognizable, provided this IP address is reachable throughout your network.
Use the ccmdb info command to set a server name (HOSTNAME) to its IP address, for a specific database. Use the following syntax:
$ ccmdb info -k hostname -v IP_address database_path
- Verify that the Informix® sqlhosts file consistently uses the same host name.
For example, verify that the server named horse has host name horse.vod.com and service name horse_horse.vod.com.
$ cd $CCM_HOME/informix/etc
$ vi sqlhosts
horse onsoctcp horse.vod.com horse_horse.vod.com
