Lines that start with WAIT

len	Length of SQL statement.
dep	Recursive depth of the cursor.
uid	Schema user id of parsing user.
oct	Oracle command type.
lid	Privilege user id.
ela	Elapsed time. 8i: in 1/1000th of a second, 9i: 1/1'000'000th of a second
tim	Timestamp. Pre-Oracle9i, the times recorded by Oracle only have a resolution of 1/100th of a second (10mS). As of Oracle9i some times are available to microsecond accuracy (1/1,000,000th of a second). The timestamp can be used to determine times between points in the trace file. The value is the value in v$timer when the line was written. If there are TIMESTAMPS in the file you can use the difference between 'tim' values to determine an absolute time.
hv	Hash id.
ad	SQLTEXT address (see v$sqlarea and v$sqltext).

Lines that start with PARSE, EXEC or FETCH

#n	n = number of cursor
c	cpu time
e	elapsed time
p	physical reads
cr	consistant reads
cu	current mode reads
mis	miss in cache (?)
r	rows processed
dep	recursive depth
og	optimizer goal
