NAME¶
tcbtest - test cases of the B+ tree database APIDESCRIPTION¶
The command ` tcbtest' 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. ` 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.Store records with keys of 8 bytes. They change as
`00000001', `00000002'...
Retrieve all records of the database above.
Remove all records of the database above.
Store records with partway duplicated keys using
concatenate mode.
Perform queueing and dequeueing.
Perform miscellaneous test of various operations.
Perform updating operations selected at random.

-rnd : select keys at random.
-wb : use the function `tcbdbget3' instead of `tcbdbget'.
-pn num : specify the number of patterns.
-dai : use the function `tcbdbaddint' instead of `tcbdbputcat'.
