NAME
       tcbmttest - test cases of the B+ tree database API

DESCRIPTION
       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 buck‐
       ets.   `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.

       Options feature the following.

	      -tl : enable the option `BDBTLARGE'.
	      -td : enable the option `BDBTDEFLATE'.
	      -tb : enable the option `BDBTBZIP'.
	      -tt : enable the option `BDBTTCBS'.
	      -tx : enable the option `BDBTEXCODEC'.
	      -xm num : specify the size of the extra mapped memory.
	      -df num : specify the unit step number of auto defragmentation.
	      -nl : enable the option `BDBNOLCK'.
	      -nb : enable the option `BDBLCKNB'.
	      -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.
