NAME
tchmttest - test cases of the hash database APIDESCRIPTION
The command `tchmttest' 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.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.
tchmttest race [-tl] [-td|-tb|-tt|-tx] [-xm num ] [-df num] [-nl|-nb] path tnum rnum [bnum [apow [fpow]]
Perform race condition test.
