When starting processes, you can use the bos start command to change their status flags to Run in both the BosConfig file and in the BOS Server's memory. You can also start processes that are temporarily disabled (processes that have a status of Run in the BosConfig file but a status of NotRun in memory) by using the bos startup command and changing only the memory state to Run. You can use the bos startup command to change a process's status in memory to Run even if its status in the BosConfig file is NotRun; thus, you can use the bos startup command to run tests on a server process without enabling it permanently.
A newly started process is a completely new instance; if you install new binaries during the time a process is shut down, they are used when you issue bos start or bos startup. If an instance of a process is already running, the only effect of these commands is to ensure that the process's status flag is set to Run in memory and, if bos start is used, in the BosConfig file; you must issue the bos restart command to start a new instance of the process.
