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.
