SETAPPC command

Use the SETAPPC command to dynamically define or modify the APPC/MVS configuration. Using this command, you can dynamically add or modify definitions for the APPC configuration without the need to edit an APPC parmlib member and issue a separate SET APPC command. However, if changes made to the APPC configuration using SETAPPC are permanent in nature, incorporate the configuration modifications into the appropriate APPC parmlib member. In this way, whenever APPC is recycled or if the system is re-IPLed, the configuration reflects the changes made by the SETAPPC command.
