TCBTEST

tcbtest − test cases of the B+ tree database API

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|−tt|−tx] [−lc num] [−nc num] [−xm num] [−df num] [−ls num] [−ca num] [−nl|−nb] [−rnd] 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] [−xm num] [−df num] [−nl|−nb] [−wb] [−rnd] path

Retrieve all records of the database above.

tcbtest remove [−mt] [−cd|−ci|−cj] [−lc num] [−nc num] [−xm num] [−df num] [−nl|−nb] [−rnd] path

Remove all records of the database above.

tcbtest rcat [−mt] [−cd|−ci|−cj] [−tl] [−td|−tb|−tt|−tx] [−lc num] [−nc num] [−xm num] [−df num] [−ls num] [−ca num] [−nl|−nb] [−pn num] [−dai|−dad|−rl|−ru] 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|−tt|−tx] [−lc num] [−nc num] [−xm num] [−df num] [−ls num] [−ca num] [−nl|−nb] path rnum [lmemb [nmemb [bnum [apow [fpow]]]]]

Perform queueing and dequeueing.

tcbtest misc [−mt] [−tl] [−td|−tb|−tt|−tx] [−nl|−nb] path rnum

Perform miscellaneous test of various operations.

tcbtest 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’.
−cd : use the comparison function ‘tccmpdecimal’.
−ci : use the comparison function ‘tccmpint32’.
−cj : use the comparison function ‘tccmpint64’.
−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’.
−lc num : specify the number of cached leaf pages.
−nc num : specify the number of cached non−leaf pages.
−xm num : specify the size of the extra mapped memory.
−df num : specify the unit step number of auto defragmentation.
−ls num : specify the maximum size of each leaf page.
−ca num : specify the capacity number of records.
−nl : enable the option ‘BDBNOLCK’.
−nb : enable the option ‘BDBLCKNB’.
−rnd : select keys at random.
−wb : use the function ‘tcbdbget3’ instead of ‘tcbdbget’.
−pn num : specify the number of patterns.
−dai : use the function ‘tcbdbaddint’ instead of ‘tcbdbputcat’.
−dad : use the function ‘tcbdbadddouble’ instead of ‘tcbdbputcat’.
−rl : set the length of values at random.
−ru : select update operations at random.

This command returns 0 on success, another on failure.
