tchmttest write [-tl] [-td|-tb|-tt|-tx] [-rc num] [-xm num] [-df num] [-nl|-nb] [-as] [-rnd] path tnum rnum [bnum [apow [fpow]]]
Store records with keys of 8 bytes. They change as ‘00000001’, ‘00000002’...

tchmttest read [-rc num] [-xm num] [-df num] [-nl|-nb] [-wb] [-rnd] path tnum
Retrieve all records of the database above.

tchmttest remove [-rc num] [-xm num] [-df num] [-nl|-nb] [-rnd] path tnum
Remove all records of the database above.

tchmttest wicked [-tl] [-td|-tb|-tt|-tx] [-nl|-nb] [-nc] path tnum rnum
Perform updating operations selected at random.

tchmttest typical [-tl] [-td|-tb|-tt|-tx] [-rc num] [-xm num] [-df num] [-nl|-nb] [-nc] [-rr num] path tnum rnum [bnum [apow [fpow]]
Perform typical operations selected at random.
