KCHASHTEST

NAME

kchashtest − command line interface to test the file hash database

DESCRIPTION

The command ‘kchashtest’ is a utility for facility test and performance test of the file hash database. This command is used in the following format. ‘path’ specifies the path of a database file. ‘rnum’ specifies the number of iterations.

kchashtest order [−th num] [−rnd] [−set|−get|−getw|−rem|−etc] [−tran] [−oat|−onl|−onl|−otl|−onr] [−apow num] [−fpow num] [−ts] [−tl] [−tc] [−bnum num] [−msiz num] [−dfunit num] [−lv] path rnum

Performs in−order tests.

kchashtest queue [−th num] [−it num] [−rnd] [−oat|−onl|−onl|−otl|−onr] [−apow num] [−fpow num] [−ts] [−tl] [−tc] [−bnum num] [−msiz num] [−dfunit num] [−lv] path rnum

Performs queuing operations.

kchashtest wicked [−th num] [−it num] [−oat|−onl|−onl|−otl|−onr] [−apow num] [−fpow num] [−ts] [−tl] [−tc] [−bnum num] [−msiz num] [−dfunit num] [−lv] path rnum

Performs mixed operations selected at random.

kchashtest tran [−th num] [−it num] [−hard] [−oat|−onl|−onl|−otl|−onr] [−apow num] [−fpow num] [−ts] [−tl] [−tc] [−bnum num] [−msiz num] [−dfunit num] [−lv] path rnum

Performs test of transaction.

Options feature the following.

−th num : specifies the number of worker threads.
−rnd
: performs random test.
−set
: performs setting operation only.
−get
: performs getting operation only.
−getw
: performs getting with a buffer operation only.
−rem
: performs removing operation only.
−etc
: performs miscellaneous operations.
−tran
: performs transaction.
−oat
: opens the database with the auto transaction option.
−oas
: opens the database with the auto synchronization option.
−onl
: opens the database with the no locking option.
−otl
: opens the database with the try locking option.
−onr
: opens the database with the no auto repair option.
−apow
num : specifies the power of the alignment of record size.
−fpow
num : specifies the power of the capacity of the free block pool.
−ts
: tunes the database with the small option.
−tl
: tunes the database with the linear option.
−tc
: tunes the database with the compression option.
−bnum
num : specifies the number of buckets of the hash table.
−msiz
num : specifies the size of the memory−mapped region.
−dfunit
num : specifies the unit step number of auto defragmentation.
−lv
: reports all errors.
−it
num : specifies the number of repetition.
−hard
: performs physical synchronization.

This command returns 0 on success, another on failure.
