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 buckets.  `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.
