Management Services Applications
The verbs and entry points you use when you write an MS application
depend on whether the MS application:
• Only sends data
• Sends and receives data
MS Applications That Only Send Data
This most simple type of application only sends data and never receives
any data fromthe SNAplus2 node. This type of application can use either
the synchronous or asynchronous entry point and needs to use only one
or both of the following verbs to send data:
• The SEND_MDS_MU verb sends data in MDS_MU format, which
SNAplus2 sends to a remote MS application.
• The TRANSFER_MS_DATA verb sends data in NMVT format,
which SNAplus2 sends to a remote MS application. The data can be
either a complete NMVT or subvectors to which SNAplus2 adds the
required NMVT header information.
For more information about the synchronous and asynchronous entry
points, see “Description of the MS API Entry Points”.
MS Applications That Both Send and Receive Data
This type of application both sends data and receives data and status
indications from the SNAplus2 node. When you write this type of
application, you must include the following verbs (except where noted,
you can use either the synchronous or asynchronous entry point):
1. Issue a CONNECT_MS_NODE verb to establish communication
with the SNAplus2 node, so that the application can register to
receive data, focal point indications, or both.
2. Register withthe SNAplus2 node to indicate the type of datathat the
application wants to receive. You must use the asynchronous entry
point to register with SNAplus2 using either or both of the following
verbs:
