While I was examining with tkprof, I noticed that there are 2 undocumented parameters (Oracle 11gR2): verbose and diag. Let’s take a look at them.
Verbose: If you set verbose=y, tkprof will provide some extra information on output files. It adds “SQL Text addres(s)” and “SQL Text Hash Value” lines for each query:
SQL ID: 3g7sxtj9d6zd3 Plan Hash: 742841275
select privilege#,nvl(col#,0),max(mod(nvl(option$,0),2))
from
objauth$ where obj#=:1 and grantee#=:2 group by privilege#,nvl(col#,0)
call count cpu elapsed disk query current rows

It also adds a summary part to the end of the output file:
Oracle command counts:
create table 23
insert 14
select 185
update 17
delete 53
create sequence 3
create view 1
create procedure 2
alter procedure 2
alter session 64

Oracle commands with error during parse:
None found.
Diag: This parameter expects you to give a file name. Tkprof can produce internal diagnostics information which seems only meaningful for Tkprof developers. Sample output of a tkprof diagnostic file:
