 **vltest read** \[-int\] *name*\

## DESCRIPTION

The command \`vltest' is a utility for facility test and performance test.  Check a database generated by the command or measure the execution time of the command.  This command is used in the following format. \`name' specifies a database name.  \`rnum' specifies the number of the records.

- **vltest write \[-int\] \[-cz\|-cy\|-cx\] \[-tune lrecmax nidxmax lcnum ncnum\] \[-fbp num\] name rnum**

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

- **vltest read \[-int\] \[-vc\] name**

  Retrieve all records of the database above.

- **vltest rdup \[-int\] \[-cz\|-cy\|-cx\] \[-cc\] \[-tune lrecmax nidxmax lcnum ncnum\] \[-fbp num\] name rnum pnum**

  Store records with partway duplicated keys using duplicate mode.

- **vltest combo \[-cz\|-cy\|-cx\] name**

  Perform combination test of various operations.

- **vltest wicked \[-c\] \[-cz\|-cy\|-cx\] name rnum**

  Perform updating operations selected at random.

Options feature the following.

**-int** : treat keys and values as objects of \`int', and use comparing function \`VL\_CMPINT'.\
 **-cz** : compress leaves in the database with ZLIB.\
 **-cy** : compress leaves in the database with LZO.\
 **-cx** : compress leaves in the database with BZIP2.\
 **-vc** : refer to volatile cache.\
 **-cc** : select \`VL\_DCAT' or \`VL\_DDUP' at random.\
 **-tune lrecmax nidxmax lcnum ncnum** : set tuning parameters.\
 **-fbp num** : set the size of the free block pool.\
 **-c** : perform comparison test with map of Cabin.

This command returns 0 on success, another on failure.  The environment variable \`QDBMDBGFD' specifies the file descriptor to output the history of updating the variable \`dpecode'.
