       tchtest - test cases of the hash database API

DESCRIPTION

       To 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.
