The column-oriented Vertica Analytics Database Platform was designed to manage large, fast-growing volumes of data and provide very fast query performance when used for data warehouses and other query-intensive applications. The following instructions show how to create a Vertica database version 9.1.1-0 in Oracle Linux Server 7.6, just for test purposes. This will be handy if we perform tests before implementing a change in the production system. But if you need to install Vertica in a real scenario, please follow all the requirements on
Vertica Installation Guide
Installing Vertica database software in a single node for test purposes
1. As root user, install dialog package with "yum install dialog".
[root@host1 ~]# yum install dialog

7. During the Vertica software installation, the user dbadmin was created.
7.1 Login as dbadmin.
7.2 Create the Vertica database with admintools command line, using --skip-fs-checks to skip file system check.
[dbadmin@host1 database]$ admintools -t create_db -c /home/dbadmin/database/ -D /home/dbadmin/database/ -s host1 -d vdb --skip-fs-checks
- Parameters used on above syntax -t | --tool -c CATALOG, the catalog is a set of files that contains information (metadata) about the objects in a database, such as the nodes, tables, constraints -D DATA, --data_path=DATA -s NODES, --hosts=NODES -d DB, --database=Database Name --skip-fs-checks Skip file system checks while creating a database (not recommended).

10. VMart Example Database
Vertica ships with a sample multi-schema database called the VMart Example Database, which represents a database that might be used by a large supermarket (VMart) to access information about its products, customers, employees, and online and physical stores. Using this example, you can create, run, optimize, and test a multi-schema database for learning purposes. Further information in
