TCBMTTEST(1)
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.
