Description: In order to execute a command, a Management Application must first initiate a Get request to read the transaction number for a given command and a given argument. The agent will assign a unique transaction number that can then be used for all subsequent requests to execute the command the transaction number was requested for. Thus, several managers executing the same command with the same argument will be assigned different transaction numbers. The manager shall use the value of transaction number to gather the response(s) from the response table (see the definition of umc1ResponseTable).
