Step 1: setting up the example environment

Stop all databases running on the same host on which you plan to install your example database.

Stop all databases running on the same host on which you plan to install your example database.

If you are unsure if other databases are running, run the Administration Tools and select View Cluster State. The State column should show DOWN values on pre-existing databases.

If databases are running, click Stop Database in the Main Menu of the Administration Tools interface and click OK.
In a terminal window, log in as the database administrator:
```
$ su dbadmin
Password: 
```
Change to the /VMart_Schema directory.
```
$ cd /opt/vertica/examples/VMart_Schema
```
Do not change directories while following this tutorial. Some steps depend on being in a specific directory.
Run the sample data generator.
```
$ ./vmart_gen
```

Let the program run with the default parameters, which you can review in the README file.

Using default parameters
datadirectory = ./
numfiles = 1
seed = 2
null = ' '
timefile = Time.txt
numfactsalesrows = 5000000
numfactorderrows = 300000
numprodkeys = 60000
numstorekeys = 250
numpromokeys = 1000
numvendkeys = 50
numcustkeys = 50000
numempkeys = 10000
numwarehousekeys = 100
numshippingkeys = 100
numonlinepagekeys = 1000
numcallcenterkeys = 200
numfactonlinesalesrows = 5000000
numinventoryfactrows = 300000
gen_load_script = false
Data Generated successfully !

If the vmart_gen executable does not work correctly, recompile it as follows, and run the sample data generator script again.
```
$ g++ vmart_gen.cpp -o vmart_gen
$ chmod +x vmart_gen
$ ./vmart_gen
```
