General
IMS discovery defaults to attempting to use the Rexx SPOC interface to
issue what are called ‘type 2 commands’ directed to a given IMS
plex.
If no connection to is available, or no data is returned, then
discovery will attempt to use ‘type 1’ commands. This will issue IMS MTO
commands that can be entered through either the EMCS console interface
or via an 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.
