Defining the logon mode for CP-CP sessions

CP-CP sessions always use the CPSVCMG logon mode. This logon mode is defined in the IBM-supplied default logon mode table, ISTINCLM. Logon mode CPSVCMG must be included in ISTINCLM in order to establish CP-CP sessions.

If no CPSVCMG logon mode is defined, CP-CP session activation will fail, and VTAM® will issue the following message:

   IST264I REQUIRED LOGMODE NAME CPSVCMG UNDEFINED.

In addition, message IST663I will display the error sense code X'08210002' (not valid mode name at CP).
