ZTRC Maps
ZPRIM
specifies the path to be traced. Valid values are:
ZREC-SIZE
specifies the size of the trace record, in bytes. Valid values are:
ZCNT
specifies the maximum number of trace records to be collected. Valid values are:
ZXDS-PAGES
specifies the number of pages allocated for trace records in the trace data extended
data segment. (The actual size of the segment is greater to account for segment
management information.) Valid values are:
ZCOLL
specifies whether the trace is to the extended data segment or to disk. Valid values
are:
ZSPI-VAL-TRUE or blank Trace the primary path.
ZSPI-VAL-FALSE Trace the backup path.
0 When modifying a trace (that is, if ZFNAME is blank), the current
record size is retained. When starting a trace (ZFNAME contains a
file name), the default record size of 120 bytes is used.
16 through 4050 The record size is set to the specified number of bytes.
0 When modifying a trace, the current maximum is retained.
When starting a trace, this value is equivalent to -1.
-1 Records are collected until the trace is stopped or until end-of-
file is encountered on the collector file (if ZWRAP is set to
FALSE).
1 through (2**32)-1 Tracing stops after the specified number of records is
captured.
0 64 pages are allocated.
4 through 1024 The specified number of pages is allocated.
ZSPI-VAL-TRUE or blank The collector actively writes blocks of trace records
from the extended segment to the trace-data disk file.
ZSPI-VAL-FALSE The only records that the collector writes to the disk
file are those in the extended segment when the trace
stops.
