Yes. The sqgen command takes in the configuration file for the trafodion cluster and generates gomon.cold, gomon.warm and other relevant scripts. These generated scripts are copied to all nodes in the cluster. These scripts are nothing but the commands to sqshell. sqstart uses either gomon.cold or gomon.warm to start the Trafodion instance.
