DVIPA target server ended record (subtype 37)

The dynamic virtual IP address (DVIPA) target server ended record is created by a sysplex distributor stack when it receives notification from a target stack that a server has closed a listening socket on a distributed port, or that a server has been quiesced using the V TCPIP,,SYSPLEX,QUIESCE command.

Creation of this SMF record is controlled by the following:

DVIPA and NODVIPA parameters on the SMFCONFIG profile statement
If DVIPA is specified, the record is created and written to the SMF MVS™ data sets.
DVIPA and NODVIPA options of the SMFSERVICE parameter on the NETMONITOR profile statement
If DVIPA is specified, the record is created and written to the real-time TCP/IP network monitoring NMI. For more information about this NMI, see Real-time TCP/IP network monitoring NMI.

See Table 1 for the contents of the TCP/IP stack identification section. For the DVIPA target server ended record, the TCP/IP stack identification section indicates STACK as the subcomponent and X'08' (event record) as the record reason.
