NAMEtchtest − test cases of the hash database API
DESCRIPTIONTo use the hash database API easily, the commands `tchtest', `tchmttest', and `tchmgr' are provided. The command `tchtest' 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. `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.
tchtest write [−mt] [−tl] [−td|−tb|−tt|−tx] [−rc num] [−xm num] [−df num] [−nl|−nb] [−as] [−rnd] path rnum [bnum [apow [fpow]]] Store records with keys of 8 bytes. They change as `00000001', `00000002'...
tchtest read [−mt] [−rc num] [−xm num] [−df num] [−nl|−nb] [−wb] [−rnd] path Retrieve all records of the database above.
tchtest remove [−mt] [−rc num] [−xm num] [−df num] [−nl|−nb] [−rnd] path Remove all records of the database above.
tchtest rcat [−mt] [−tl] [−td|−tb|−tt|−tx] [−rc num] [−xm num] [−df num] [−nl|−nb] [−pn num] [−dai|−dad|−rl|−ru] path rnum [bnum [apow [fpow]]] Store records with partway duplicated keys using concatenate mode.
tchtest misc [−mt] [−tl] [−td|−tb|−tt|−tx] [−nl|−nb] path rnum Perform miscellaneous test of various operations.
tchtest wicked [−mt] [−tl] [−td|−tb|−tt|−tx] [−nl|−nb] path rnum Perform updating operations selected at random. Options feature the following. −mt : call the function `tchdbsetmutex'.
−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'.
−pn num : specify the number of patterns.
−dai : use the function `tchdbaddint' instead of `tchdbputcat'.
−dad : use the function `tchdbadddouble' instead of `tchdbputcat'.
−rl : set the length of values at random.
−ru : select update operations at random.
This command returns 0 on success, another on failure.
