NAME

ashdata − RWP*Load Simulator ashdata table

DESCRIPTION

The ashdata table is used by the standard oltp workload and contains all ash samples for each run.

DECLARATION

create table ashdata
( runnumber number not null
, second number not null
, cpu number
, e1 number
, e2 number
, e3 number
, e4 number
, e5 number
, e6 number
, e7 number
, e8 number
, other number
, constraint ashdata_pk primary key(runnumber, second)
)

COLUMNS

runnumber

The primary key of the rwlrun table.

second

The number of seconds into the run when the ash sample was taken.

cpu

The count of sessions that are on cpu in that particular sample.

e1 e2 ... e8

The count of sessions that are waiting on some explicitly named wait event.

other

The count of sessions that are waiting on any other wait event.

NOTES

Whenever a run terminates normally, all ash samples that are taken every second are inserted into this table. The top eight wait events during the whole run will have counts in the e1 until e8 columns, and the rwlash table contains the actual wait event names.

As an example, if the top wait event in any run is ’log file sync’ and the second most frequent wait event is ’cell single block physical read’, the e1 and e2 columns in this table contains the number of sessions that in some particular sample were waiting on these two wait events.
