The following procedures guide you through the process.
Delete the SYSTEM_AVG_EMM_PACKETS Entry from the dncs User .profile File
The SYSTEM_AVG_EMM_PACKETS variable is the average number of EMMs per
STB sent by the emmDistributor process. Setting this variable to 10 or 11 keeps the
number of packets required to deliver the EMMs to the desired value of 3 per STB. In
SR 5.0, the average packets value is set to 3 by default so this environmental variable
is not needed. To delete this variable from the dncs user .profile file, follow these
instructions.
1 From the dncs xterm window, search for the variable by typing the following
