The command `vltest' is a utility for facility test and performance test. Check a database generated by the command or measure the execution time of the command. This command is used in the following format. `name' specifies a database name. `rnum' specifies the number of the records.

Store records with keys of 8 bytes. They change as `00000001', `00000002'...
Retrieve all records of the database above.
Store records with partway duplicated keys using duplicate mode.
Perform combination test of various operations.
Perform updating operations selected at random.

Options feature the following.

-int : treat keys and values as objects of `int', and use comparing function `VL_CMPINT'.
-cz : compress leaves in the database with ZLIB.
-cy : compress leaves in the database with LZO.
-cx : compress leaves in the database with BZIP2.
-vc : refer to volatile cache.
-cc : select `VL_DCAT' or `VL_DDUP' at random.
-tune lrecmax nidxmax lcnum ncnum : set tuning parameters.
-fbp num : set the size of the free block pool.
-c : perform comparison test with map of Cabin.

This command returns 0 on success, another on failure. The environment variable `QDBMDBGFD' specifies the file descriptor to output the history of updating the variable `dpecode'.
