DESCRIPTION

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.
