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.
