RTP data vector (X'000300010001')

The format of the RTP data vector is shown in Table 1. RTP data vectors are built for each RTP specified in a collect request.

Table 1. RTP data vector
Byte	Type	Description
8–9	binary	First byte Bit setting B'0000 0000' Normal collect B'1000 0000' Exit called due to HPR path switch B'0100 0000' Exit called because RTP is being deleted B'0010 0000' Exit called due to HPR path switch with CP name change. The `New remote network ID` field and the `New remote CP name` field are set. Second byte is reserved.
10–17	binary	Local NCE
18–25	binary	Local TCID
26–33	binary	Rapid Transport Protocol (RTP) Physical Unit
34–41	EBCDIC	Remote network ID
42–49	EBCDIC	Remote CP name
50–57	EBCDIC	New Remote network ID
58–65	EBCDIC	New remote CP name
66–73	binary	Remote NCE
74–81	binary	Remote TCID
82	binary	RTP state
83–86	binary	HPR path switch timer
87–90	binary	Round-trip delay
91–94	binary rolling counter	Number of bytes sent over the RTP
95–98	binary rolling counter	Number of bytes received over the RTP
99–102	binary rolling counter	Number of PIUs that were first in segment sent over the RTP
103–106	binary rolling counter	Number of PIUs that were middle in segment sent over the RTP
107–110	binary rolling counter	Number of PIUs that were last in segment sent over the RTP
111–114	binary rolling counter	Number of PIUs that were not segmented sent over the RTP
115–118	binary rolling counter	Number of PIUs that were first in segment received over the RTP
119–122	binary rolling counter	Number of PIUs that were middle in segment received over the RTP
123–126	binary rolling counter	Number of PIUs that were last in segment received over the RTP
127–130	binary rolling counter	Number of PIUs that were not segmented received over the RTP
131–134	binary rolling counter	Number of times the allowed send rate changed
135–136	binary rolling counter	HPR path switch attempts initiated by other RTP endpoint
137–138	binary rolling counter	Total number of HPR path switch attempts initiated by this VTAM®
139–140	binary rolling counter	HPR path switch attempts due to operator or VTAM command. Path switch attempts due to any other failure (such as link failure or node failure) can be calculated by subtracting this value from the total number of path switch attempts.
141–142	binary rolling counter	Total number of unsuccessful route selection attempts initiated by this VTAM during HPR path switch
143–144	binary rolling counter	Unsuccessful HPR path switch due to operator command. The number of unsuccessful path switches that originated due to any other failure (such as link failure or node failure) can be calculated by subtracting this value from the total number of unsuccessful path switch attempts.
145–148	binary	Number of active LU-LU sessions using the RTP
149–152	binary rolling counter	Amount of time in seconds that back pressure has been applied
153–154	binary rolling counter	Total number of times that back pressure has been applied
155–156	binary rolling counter	Number of times that back pressure has been applied due to HPR path switch
157–158	binary rolling counter	Number of times that back pressure has been applied due queue depth exceeded. The number of times that back pressure has been applied due to storage shortage can be calculated by subtracting the above two counts from the total count.
159–162	binary rolling counter	Number of retransmitted NLPs
163–166	binary rolling counter	Current number of unacknowledged buffers
