NAMEtcbmttest − test cases of the B+ tree database API
DESCRIPTIONThe 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.
This command returns 0 on success, another on failure.
