SMS trace record output

Figure 1 shows an example of SMS trace output. The trace fields are explained in Table 1. In addition to the fields described here, other operating-system-dependent fields may appear. These fields are described in Table 1.

Two separate records will be printed, and they may be separated by another trace entry.

Table 1. Fields in the SMS trace
Field header	Meaning
Pool ID	The first field in each record. Pool ID identifies the buffer pool. Pool IDs and their corresponding buffer pool names are: AP Application program pageable pool (APBUF) BS Boundary session block pool (BSBUF) CR Copied RPL pool (CRPLBUF) CRA4 Component recovery area CRA8 Component recovery area IO Fixed I/O pool (IOBUF) LF Large fixed pool (LFBUF) LP Large pageable pool (LPBUF) SF Small fixed pool (SFBUF) SP Small pageable pool (SPBUF) TI HPDT Services (TIBUF) UE User exit control block (UECB) (obsolete) XD XID pool (XDBUF)
MAXU	The maximum number of buffers in the pool that are in use at any time since the last trace record is written.
MAXQ	The maximum number of requests for buffers that are queued waiting for storage at any time since the last trace record is written.
AVNO	The number of available buffers (those not in use at the time the trace record is written).
TEXP	The number of times the buffer pool is expanded since the last trace record is written.
MBUF	The maximum number of buffers that are in the pool at any time since the last trace record is written. This includes both used and unused buffers.
TOTL	The total number of buffers that are in the pool at the time this record is written. This includes both used and unused buffers.
TOTAL	The amount of CSA storage in use by VTAM® at the time this record is written.
MAX	The largest amount of CSA storage used by VTAM since the last SMS buffer trace.
FREE QUEUE	The amount of CSA storage allocated to VTAM that is waiting to be freed.
TI	Buffer pool supporting HPDT services
CRA4	Component recovery area (4 KB).
CRA8	Component recovery area (8 KB).
