## NAME

tcfmttest - test cases of the fixed-length database API

## DESCRIPTION

The command \`**tcfmttest**' is a utility for facility test under multi-thread situation.  This command is used in the following format.  \`*path*' specifies the path of a database file.  \`*tnum*' specifies the number of running threads.  \`*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.

**tcfmttest write** \[**-nl**\|**-nb**\] \[**-rnd**\] *path* *tnum* *rnum* \[*width* \[*limsiz*\]\]

Store records with keys of 8 bytes.  They change as \`00000001', \`00000002'...

**tcfmttest read** \[**-nl**\|**-nb**\] \[**-wb**\] \[**-rnd**\] *path* *tnum*

Retrieve all records of the database above.

**tcfmttest remove** \[**-nl**\|**-nb**\] \[**-rnd**\] *path* *tnum*

Remove all records of the database above.

**tcfmttest wicked** \[**-nl**\|**-nb**\] \[**-nc**\] *path* *tnum* *rnum*

Perform updating operations selected at random.

**tcfmttest typical** \[**-nl**\|**-nb**\] \[**-nc**\] \[**-rr** *num*\] *path* *tnum* *rnum* \[*width* \[*limsiz*\]\]

Perform typical operations selected at random.

Options feature the following.

**-nl** : enable the option \`FDBNOLCK'.\
 **-nb** : enable the option \`FDBLCKNB'.\
 **-rnd** : select keys at random.\
 **-wb** : use the function \`tcfdbget4' instead of \`tcfdbget2'.\
 **-nc** : omit the comparison test.\
 **-rr** *num* : specify the ratio of reading operation by percentage.\

This command returns 0 on success, another on failure.
