DESCRIPTION

The command `tcbtest' 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. `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.


tcbtest write [-mt] [-cd|-ci|-cj] [-tl] [-td|-tb] [-lc num] [-nc num] [-ls num] [-nl|-nb] path rnum [lmemb [nmemb [bnum [apow [fpow]]]]]
Store records with keys of 8 bytes. They change as `00000001', `00000002'...

tcbtest read [-mt] [-cd|-ci|-cj] [-lc num] [-nc num] [-nl|-nb] [-wb] path
Retrieve all records of the database above.

tcbtest remove [-mt] [-cd|-ci|-cj] [-lc num] [-nc num] [-nl|-nb] path
Remove all records of the database above.

tcbtest rcat [-mt] [-cd|-ci|-cj] [-tl] [-td|-tb] [-lc num] [-nc num] [-ls num] [-nl|-nb] [-pn num] [-rl] path rnum [lmemb [nmemb [bnum [apow [fpow]]]]]
Store records with partway duplicated keys using concatenate mode.

tcbtest queue [-mt] [-cd|-ci|-cj] [-tl] [-td|-tb] [-lc num] [-nc num] [-ls num] [-nl|-nb] path rnum [lmemb [nmemb [bnum [apow [fpow]]]]]
Perform queueing and dequeueing.

tcbtest misc [-mt] [-tl] [-td|-tb] [-nl|-nb] path rnum
Perform miscellaneous test of various operations.

tcbtest wicked [-mt] [-tl] [-td|-tb] [-nl|-nb] path rnum
Perform updating operations selected at random.

Options feature the following.

-mt : call the function `tchdbsetmutex'.
-cd : use the comparison function `tcbdbcmpdecimal'.
-ci : use the comparison function `tcbdbcmpint32'.
-cj : use the comparison function `tcbdbcmpint64'.
-tl : enable the option `BDBTLARGE'.
-td : enable the option `BDBTDEFLATE'.
-tb : enable the option `BDBTTCBS'.
-lc num : specify the number of cached leaf pages.
-nc num : specify the number of cached non-leaf pages.
-ls num : specify the maximum size of each leaf page.
-nl : enable the option `BDBNOLCK'.
-nb : enable the option `BDBLCKNB'.
-wb : use the function `tcbdbget3' instead of `tcbdbget'.
-pn num : specify the number of patterns.
-rl : set the length of values at random.

This command returns 0 on success, another on failure.
