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]pathrnum

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]pathrnum

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]pathrnum

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]pathrnum

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.
