       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.
