Controls the topology services subsystem.
cthatsctrl { -a [ -p port-number ] │ -s │ -k │ -d │ -b │ -t │ -o │ -r │ -h }
The cthatsctrl control command controls the operation of the topology services subsystem. The subsystem is under the control of the system resource controller (SRC) and belongs to a subsystem group called cthats. Associated with each subsystem is a daemon and a command that configures and starts the daemon.
An instance of the topology services subsystem runs on every node of a cluster.
Adding the subsystem
The service name that is entered in the /etc/services file is cthats.
Starting the subsystem
When the -s flag is specified, the control command uses the startsrc command to start to start the topology services subsystem, cthats.
Stopping the subsystem
When the -k flag is specified, the control command uses the stoptsrc command to stop the topology services subsystem, cthats.
Deleting the subsystem
Rebuilding the configuration
When the -b flag is specified, the control command reads the configuration information from the cluster data and builds a configuration file, machines.lst, for the topology services daemon.
Turning tracing on
When the -t flag is specified, the control command turns tracing on for the topology services daemon using the traceson command.
Turning tracing off
When the -o flag is specified, the control command turns tracing off (returns it to its default level) for the topology services daemon using the tracesoff command.
Refreshing the subsystem
When the -r flag is specified, the control command refreshes the subsystem using the refresh command. The -r flag signals the daemon to read the rebuilt information.
