Management Services Indications
MDS_MU_RECEIVED
Chapter 4 101
MDS_MU_RECEIVED
SNAplus2 uses this data indication to route an MDS_MU to an
MDS-level application in the following cases:
• A remote MDS-level application has sent an MDS_MU, and this
application has used REGISTER_MS_APPLICATION to accept
MDS_MUs.
• A remote application has sent an NMVT, and this application has
used REGISTER_NMVT_APPLICATION to accept NMVTs after
conversion to MDS_MUs. For information about how SNAplus2
determines which MS application receives an incoming NMVT, see
“NMVT Routing”.
To return the MDS_MU_RECEIVED indication, SNAplus2 uses the
callback routine that the application supplied on the
REGISTER_MS_APPLICATION or REGISTER_NMVT_APPLICATION
verb. For more information about the requirements for this callback
routine, see “The Callback Routine Specified on the ms_async Entry
Point”.
