# Integrating Decisions with External Oracle Database

## Overview

**Oracle Database** is a multi-model database management system commonly used for running online transaction processing, data warehousing, and mixed database workloads. This tutorial demonstrates how to Integrate **Decisions** with Oracle Database.

## Oracle Integration

This example, will demonstrate how to Integrate Decisions with **Oracle Database**. Once the table has been added, [Specific tables](/v9/docs/integrate-with-database-table) and custom queries can be created in the connection folder.

1. Begin by Creating Database Connection. In the**Portal,** navigate to **System > Integrations > Databases** and click CREATE CONNECTION on the Folder Actions Panel. ![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/2024-07-16_12h00_13.png) 2. First, define a desirable **Connection Name**.

3. Then, from the **Database Type** drop down, pick **ORACLE**.

Next, there are option to specify properties to connect to **Oracle Server**. Which are:

| Use TNS |
| --- |
| Database Name |
| User Name |
| Password |
| Host Name |
| Port |

4. Click TEST before saving. If the Test Status is **Success**, then click OK to save this Database Integration. 5. The database connection being created can be found in **System > Integrations > Databases**Folder.

## Fetch Size

In v8.12 and higher the Steps Raw SQL and Run Query [QueryName] have a configuration under CONNECTION SETTINGS called Fetch Size.

This setting allows for control over how many records are within a data packet. Either Step will return all records, but the driver will only fetch the number of records entered at a time. There are performance implications to how this is set. A database with 800,000 records will likely timeout if the fetch size is too low or too high. A single fetch of 800,000 records or 800,000 fetches of a single record will cause performance issues. The recommended way to determine the best performance is to start with a value of 100 and then try 500, 1000, and finally 5000.
