The command ‘tcbmttest’ 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. ‘tnum’ specifies the number of running threads. ‘rnum’ specifies the number of iterations. ‘lmemb’ specifies the number of members in each leaf page. ‘nmemb’ specifies the number of members in each non-leaf page. ‘bnum’ specifies the number of buckets. ‘apow’ specifies the power of the alignment. ‘fpow’ specifies the power of the free block pool.

tcbmttest write [-tl] [-td|-tb|-tt|-tx] [-xm num] [-df num] [-nl|-nb] [-rnd] path tnum rnum [lmemb [nmemb [bnum [apow [fpow]]]]]
Store records with keys of 8 bytes. They change as ‘00000001’, ‘00000002’...

tcbmttest read [-xm num] [-df num] [-nl|-nb] [-wb] [-rnd] path tnum
Retrieve all records of the database above.

tcbmttest remove [-xm num] [-df num] [-nl|-nb] [-rnd] path tnum
Remove all records of the database above.

tcbmttest wicked [-tl] [-td|-tb|-tt|-tx] [-nl|-nb] [-nc] path tnum rnum
Perform updating operations selected at random.

tcbmttest typical [-tl] [-td|-tb|-tt|-tx] [-xm num] [-df num] [-nl|-nb] [-nc] [-rr num] path tnum rnum [lmemb [nmemb [bnum [apow [fpow]]]]]
Perform typical operations selected at random.

tcbmttest race [-tl] [-td|-tb|-tt|-tx] [-xm num] [-df num] [-nl|-nb] path tnum rnum [lmemb [nmemb [bnum [apow [fpow]]]]]
Perform race condition test.

-tl : enable the option ‘BDBTLARGE’.
-td : enable the option ‘BDBTDEFLATE’.

-nb : enable the option ‘BDBLCKNB’.
-rnd : select keys at random.
