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
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.
