vltest read [-int] name
vltest rdup [-int] [-cz|-cy|-cx] [-cc] [-tune lrecmax nidxmax lcnum ncnum] [-fbp num] name rnum pnum

DESCRIPTION

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.
vltest write [-int] [-cz|-cy|-cx] [-tune lrecmax nidxmax lcnum ncnum] [-fbp
num] name rnum

Store records with keys of 8 bytes. They change as ‘00000001’, ‘00000002’...

vltest read [-int] [-vc] name

Retrieve all records of the database above.

vltest rdup [-int] [-cz|-cy|-cx] [-cc] [-tune lrecmax nidxmax lcnum ncnum]
[-fbp num] name rnum pnum

Store records with partway duplicated keys using duplicate mode.

vltest combo [-cz|-cy|-cx] name

Perform combination test of various operations.

vltest wicked [-c] [-cz|-cy|-cx] name rnum

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’.
