kchashtest (1)

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.

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.
