tctmttest \- test cases of the table database API

.SH DESCRIPTION
.PP
The command `\fBtctmttest\fR' is a utility for facility test under multi\-thread situation.  This command is used in the following format.  `\fIpath\fR' specifies the path of a database file.  `\fItnum\fR' specifies the number of running threads.  `\fIrnum\fR' specifies the number of iterations.  `\fIbnum\fR' specifies the number of buckets.  `\fIapow\fR' specifies the power of the alignment.  `\fIfpow\fR' specifies the power of the free block pool.
