Administering Configuration Files

Two configuration files are used by CCM tool: clusters and serialports. These files are created automatically by cluster_tool_setup, which places them in  /etc. (These files are not updated automatically; if you later change cluster characteristics, you must update these files manually.)

The clusters File

The clusters configuration file maps a cluster name to the list of host names that make up the cluster Each line in this database corresponds to a cluster. The format is:

clustername hostname-1 hostname-2 [...] hostname-n

For example:

cities
chartres izmir tampico inchon essen sydney

The clusters file is used to map cluster names to host names on the command line and in the Select Hosts dialog.

The serialports File

The serialports file maps each host name to the terminal concentrator and the terminal concentrator serial port to which it is connected. Each line in this database specifies a separate serial port using the format:

hostname terminal_concentrator serial_port

For example:

chartres
cities-tc 5002
izmir
cities-tc 5003

The serialports file is used by cconsole to determine which terminal concentrator and serial ports to connect to for the various cluster nodes that have been specified on the command line or the Select Hosts dialog.
