Tuning statistics file report for channel-to-channel adapters

Table 1 shows the format of the record written to the appropriate tuning statistics file.

Table 1. Record format for channel-to-channel adapters
Offset	Length	Format	Description
0	2	Binary	Record length
2	3	Binary	Reserved
5	1	Binary	Record type
6	4	Binary	Time record moved to buffer
10	4	Packed	Date: 01YYDDDF
14	4	EBCDIC	System identification
18	8	EBCDIC	CTCA name (ID)
26	4	Binary	Dump load restart requests (DLRMAX)
30	4	Binary	Normal-sized channel program count (CHNRM)
34	4	Binary	Large-sized channel program count (CHMAX)
38	4	Binary	Total attention interrupts received (ATTN)
42	4	Binary	Number of write buffers used (WRBUF). For packed channel programs the counts represent the number of bytes read or written. For old style (non-packed format) it is the number of buffers.
46	4	Binary	Number of PIUs inbound (IPIU)
50	4	Binary	Number of PIUs outbound (OPIU)
54	4	Binary	Total input bytes used (RDBUF). For packed channel programs the counts represent the number of bytes read or written. For old style (non-packed format) it is the number of buffers.
58	4	Binary	Number of slowdowns (SLODN)
62	1	Binary	CTCA extension length (including this field)
63	1	Binary	CTCA attachment type
64	2	EBCDIC	CTCA version = X'F0F1'
66	4	Binary	Channel program starts because of timer trigger (TIMERS)
70	4	Binary	Channel program starts because of queue depth limit trigger (QDPTH)
74	4	Binary	Channel program starts because of destination capacity limit trigger (BUFCAP)
78	4	Binary	Channel program starts because of high priority request trigger (PRI)
82	32	Binary	Reserved
