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.
vltestwrite[-int][-cz|-cy|-cx][-tunelrecmaxnidxmaxlcnumncnum][-fbpnum]namernum
Store records with keys of 8 bytes. They change as `00000001', `00000002'...
vltestread[-int][-vc]name
Retrieve all records of the database above.
vltestrdup[-int][-cz|-cy|-cx][-cc][-tunelrecmaxnidxmaxlcnumncnum][-fbpnum]namernumpnum
Store records with partway duplicated keys using duplicate mode.
vltestcombo[-cz|-cy|-cx]name
Perform combination test of various operations.
vltestwicked[-c][-cz|-cy|-cx]namernum
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.
-tunelrecmaxnidxmaxlcnumncnum : set tuning parameters.
-fbpnum : 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'.
