The command `tctmttest' is a utility for facility test under multi-thread situation. This command is used in the following format. `path' specifies the path of a database file. `tnum' specifies the number of running threads. `rnum' specifies the number of iterations. `bnum' specifies the number of buckets. `apow' specifies the power of the alignment. `fpow' specifies the power of the free block pool.

tctmttest write [-tl] [-td|-tb|-tt|-tx] [-rc num] [-lc num] [-nc num] [-xm num] [-df num] [-ip] [-is] [-in] [-it] [-if] [-ix] [-nl|-nb] [-rnd] path tnum rnum [bnum [apow [fpow]]]

Store records with columns "str", "num", "type", and "flag".

tctmttest read [-rc num] [-lc num] [-nc num] [-xm num] [-df num] [-nl|-nb] [-rnd] path tnum

Retrieve all records of the database above.

tctmttest remove [-rc num] [-lc num] [-nc num] [-xm num] [-df num] [-nl|-nb] [-rnd] path tnum

Remove all records of the database above.

tctmttest wicked [-tl] [-td|-tb|-tt|-tx] [-nl|-nb] path tnum rnum

Perform updating operations selected at random.

tctmttest typical [-tl] [-td|-tb|-tt|-tx] [-rc num] [-lc num] [-nc num] [-xm num] [-df num] [-nl|-nb] [-rr num] path tnum rnum [bnum [apow [fpow]]

Perform typical operations selected at random.
