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'.
