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

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