IMS DB/DC discovery requires that IMS MTO commands be entered through either the EMCS console interface or via the IMS outstanding reply message. If the IMS CMDMCS parameter is other than “N” then by default IMS commands issued by discovery scripts will be issued through the IMS Subsystem Interface (SSI) using the IMSID as the command prefix. If CMDMCS is specified as “N” then commands will be issued using the IMS outstanding reply message.
IMS DBCTL discovery requires that commands must be issued through the EMCS console using the IMS Subsystem Interface (SSI) using the IMSID as the command prefix. For discovery of IMS DBCTL, the CMDMCS parameter must be other than “N”.
