TCFTEST

tcftest − test cases of the fixed-length database API

The command ‘tcftest’ is a utility for facility test and performance test. This command is used in the following format. ‘path’ specifies the path of a database file. ‘rnum’ specifies the number of iterations. ‘width’ specifies the width of the value of each record. ‘limsiz’ specifies the limit size of the database file.

tcftest write [−mt] [−nl|−nb] [−rnd] path rnum [width [limsiz]]

Store records with keys of 8 bytes. They change as ‘00000001’, ‘00000002’...

tcftest read [−mt] [−nl|−nb] [−wb] [−rnd] path

Retrieve all records of the database above.

tcftest remove [−mt] [−nl|−nb] [−rnd] path

Remove all records of the database above.

tcftest rcat [−mt] [−nl|−nb] [−pn num] [−dai|−dad|−rl] path rnum [limsiz]]

Store records with partway duplicated keys using concatenate mode.

tcftest misc [−mt] [−nl|−nb] path rnum

Perform miscellaneous test of various operations.

tcftest wicked [−mt] [−nl|−nb] path rnum

Perform updating operations selected at random.

Options feature the following.

−mt : call the function ‘tcfdbsetmutex’.
−nl : enable the option ‘FDBNOLCK’.
−nb : enable the option ‘FDBLCKNB’.
−rnd : select keys at random.
−wb : use the function ‘tcfdbget4’ instead of ‘tcfdbget2’.
−pn num : specify the number of patterns.
−dai : use the function ‘tcfdbaddint’ instead of ‘tcfdbputcat’.
−dad : use the function ‘tcfdbadddouble’ instead of ‘tcfdbputcat’.
−rl : set the length of values at random.

This command returns 0 on success, another on failure.
