An IBM Connections environment consists in many servers that run various software product integrated with IBM Connections. The communications between those servers is based on TCP connections and name resolution through dynamic name server (DNS), so you must have a DNS server configured on your environment, because during the installation and configuration process, you must provide host names of the following server:
- Database servers
- LDAP Servers
- WebSphere Application Servers
- Web Servers
- Other components such as Cognos server, Domino mail server, Identity Manager server, WebSphere Portal server, and Security Management server
Check if the servers can communicate with each other with the ping
command. Run the following command to check the host name resolution on all the servers of your environment:
For example, from a WebSphere Application Server server, you can try to ping a web server, LDAP server, database server and all other servers that will be part of the IBM Connections deployment such as Cognos server and Tivoli Directory Integrator server.
The following figure shows that we can ping the IBM HTTP server (con-ihs01.itso.ibm.com) and LDAP server (ldap-dom.itso.ibm.com) from WebSphere Application Server (con-dmgr.itso.ibm.com) in our lab environment.
