The command `tcftest' is a utility for facility test and performance test. This command is used in the
following format. `path' specifies the path of a database file. `rnum' specifies the number of
iterations. `width' specifies the width of the value of each record. `limsiz' specifies the limit size
of the database file.
tcftestwrite [-mt] [-nl|-nb] [-rnd] pathrnum [width [limsiz]]
Store records with keys of 8 bytes. They change as `00000001', `00000002'...
tcftestread [-mt] [-nl|-nb] [-wb] [-rnd] path
Retrieve all records of the database above.
tcftestremove [-mt] [-nl|-nb] [-rnd] path
Remove all records of the database above.
tcftestrcat [-mt] [-nl|-nb] [-pnnum] [-dai|-dad|-rl] pathrnum [limsiz]]
Store records with partway duplicated keys using concatenate mode.
tcftestmisc [-mt] [-nl|-nb] pathrnum
Perform miscellaneous test of various operations.
tcftestwicked [-mt] [-nl|-nb] pathrnum
Perform updating operations selected at random.
Options feature the following.
-mt : call the function `tcfdbsetmutex'.
-nl : enable the option `FDBNOLCK'.
-nb : enable the option `FDBLCKNB'.
-rnd : select keys at random.
-wb : use the function `tcfdbget4' instead of `tcfdbget2'.
-pnnum : specify the number of patterns.
-dai : use the function `tcfdbaddint' instead of `tcfdbputcat'.
-dad : use the function `tcfdbadddouble' instead of `tcfdbputcat'.
-rl : set the length of values at random.
This command returns 0 on success, another on failure.
