The command ` tchmttest' is a utility for facility test under multi-thread situation. 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. ` bnum' specifies the number of buckets. `apow' specifies the power of the alignment. ` fpow' specifies the power of the free block pool.
 
tchmttest write [-tl] [-td|-tb|-tt|-tx] [-rc num ] [-xm num] [-df num] [-nl|-nb] [-as] [ -rnd] path tnum rnum [ bnum [apow [fpow]]]
Store records with keys of 8 bytes. They change as `00000001', `00000002'...
 
tchmttest read [-rc num] [-xm num ] [-df num] [-nl| -nb] [-wb] [-rnd] path tnum
Retrieve all records of the database above.
 
tchmttest remove [-rc num] [-xm num ] [-df num] [-nl| -nb] [-rnd] path tnum
Remove all records of the database above.
 
tchmttest wicked [-tl] [-td|-tb|-tt|-tx] [-nl|-nb] [-nc] path tnum rnum
Perform updating operations selected at random.
 
tchmttest typical [-tl] [-td|-tb|-tt|-tx] [-rc num ] [-xm num] [-df num] [-nl|-nb] [-nc] [ -rr num] path tnum rnum [bnum [apow [ fpow]]
Perform typical operations selected at random.
 
tchmttest race [-tl] [-td|-tb|-tt|-tx] [-xm num ] [-df num] [-nl| -nb] path tnum rnum [bnum [apow [ fpow]]
Perform race condition test.
Options feature the following.
-tl : enable the option `HDBTLARGE'.
 
-td : enable the option `HDBTDEFLATE'.
 
-tb : enable the option `HDBTBZIP'.
 
-tt : enable the option `HDBTTCBS'.
 
-tx : enable the option `HDBTEXCODEC'.
 
-rc num : specify the number of cached records.
 
-xm num : specify the size of the extra mapped memory.
 
-df num : specify the unit step number of auto defragmentation.
 
-nl : enable the option `HDBNOLCK'.
 
-nb : enable the option `HDBLCKNB'.
 
-as : use the function `tchdbputasync' instead of `tchdbput'.
 
-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.
