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. Options feature the following. -tl : enable the option `HDBTLARGE'. -td : enable the option `HDBTDEFLATE'. -tb : enable the option `HDBTBZIP'. -tt : enable the option `HDBTTCBS'. -tx : enable the option `HDBTEXCODEC'. -rc num : specify the number of cached records. -xm num : specify the size of the extra mapped memory. -df num : specify the unit step number of auto defragmentation. -nl : enable the option `HDBNOLCK'. -nb : enable the option `HDBLCKNB'. -as : use the function `tchdbputasync' instead of `tchdbput'. -rnd : select keys at random. -wb : use the function `tchdbget3' instead of `tchdbget'. -nc : omit the comparison test. -rr num : specify the ratio of reading operation by percentage. This command returns 0 on success, another on failure. SEE ALSO tchtest(1), tchmgr(1), tchdb(3), tokyocabinet(3) Man Page 2012-08-18 TCHMTTEST(1)
