TCTTEST

tcttest − test cases of the table database API

The command ‘tcttest’ 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. ‘bnum’ specifies the number of buckets. ‘apow’ specifies the power of the alignment. ‘fpow’ specifies the power of the free block pool.

tcttest write [−mt] [−tl] [−td|−tb|−tt|−tx] [−rc num] [−lc num] [−nc num] [−xm num] [−df num] [−ip] [−is] [−in] [−it] [−if] [−ix] [−nl|−nb] [−rnd] path rnum [bnum [apow [fpow]]]

Store records with columns "str", "num", "type", and "flag".

tcttest read [−mt] [−rc num] [−lc num] [−nc num] [−xm num] [−df num] [−nl|−nb] [−rnd] path

Retrieve all records of the database above.

tcttest remove [−mt] [−rc num] [−lc num] [−nc num] [−xm num] [−df num] [−nl|−nb] [−rnd] path

Remove all records of the database above.

tcttest rcat [−mt] [−tl] [−td|−tb|−tt|−tx] [−rc num] [−lc num] [−nc num] [−xm num] [−df num] [−ip] [−is] [−in] [−it] [−if] [−ix] [−nl|−nb] [−pn num] [−dai|−dad|−rl|−ru] path rnum [bnum [apow [fpow]]]

Store records with partway duplicated keys using concatenate mode.

tcttest misc [−mt] [−tl] [−td|−tb|−tt|−tx] [−nl|−nb] path rnum

Perform miscellaneous test of various operations.

tcttest wicked [−mt] [−tl] [−td|−tb|−tt|−tx] [−nl|−nb] path rnum

Perform updating operations selected at random.

Options feature the following.

−mt : call the function ‘tctdbsetmutex’.
−tl : enable the option ‘TDBTLARGE’.
−td : enable the option ‘TDBTDEFLATE’.
−tb : enable the option ‘TDBTBZIP’.
−tt : enable the option ‘TDBTTCBS’.
−tx : enable the option ‘TDBTEXCODEC’.
−rc num : specify the number of cached records.
−lc num : specify the number of cached leaf pages.
−nc num : specify the number of cached non−leaf pages.
−xm num : specify the size of the extra mapped memory.
−df num : specify the unit step number of auto defragmentation.
−ip : create the number index for the primary key.
−is : create the string index for the column "str".
−in : create the number index for the column "num".
−it : create the string index for the column "type".
−if : create the token inverted index for the column "flag".
−ix : create the q−gram inverted index for the column "text".
−nl : enable the option ‘TDBNOLCK’.
−nb : enable the option ‘TDBLCKNB’.
−rnd : select keys at random.
−pn num : specify the number of patterns.
−dai : use the function ‘tctdbaddint’ instead of ‘tctdbputcat’.
−dad : use the function ‘tctdbadddouble’ instead of ‘tctdbputcat’.
−rl : set the length of values at random.
−ru : select update operations at random.

This command returns 0 on success, another on failure.
