To change the properties of query groups or streams:
Note that when you have started a query group using the sdpcqlstart command with the -reload option specified, the settings cannot be changed for some parameters in the property files. To change the settings of such parameters, you must first delete the query group and then register and start a new query group. For details about the parameters whose settings cannot be changed, see 8.7.1 Details of the query group property file or 8.8.1 Details of the stream property file.
