tctmttest − test cases of the table database API

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.

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.
