## NAME

crtest - test cases for QDBM Curia

## SYNOPSIS

**crtest write** \[-s\] \[-lob\] *name* *rnum* *bnum* *dnum*\
 **crtest read** \[-wb\] \[-lob\] *name*\
 **crtest rcat** \[-c\] *name* *rnum* *bnum* *dnum* *pnum* *align*\
 **crtest combo** *name*\
 **crtest wicked** \[-c\] *name* *rnum*

## DESCRIPTION

The command \`crtest' 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 records.  \`bnum' specifies the number of elements of a bucket array.  \`dnum' specifies the number of division of a database.  \`pnum' specifies the number of patterns of the keys.  \`align' specifies the basic size of alignment.  \`fbpsiz' specifies the size of the free block pool.

- **crtest write \[-s\] \[-lob\] name rnum bnum dnum**

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

- **crtest read \[-wb\] \[-lob\] name**

  Retrieve all records of the database above.

- **crtest rcat \[-c\] name rnum bnum dnum pnum align fbpsiz**

  Store records with partway duplicated keys using concatenate mode.

- **crtest combo name**

  Perform combination test of various operations.

- **crtest wicked \[-c\] name rnum**

  Perform updating operations selected at random.

Options feature the following.

**-s** : make the files sparse.\
 **-lob** : handle large objects.\
 **-wb** : use the function \`crgetwb' instead of the function \`crget'.\
 **-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'.
