2 – Database connections

Database connections are considered as a pool or resources, which can be used for several purposes. This core functionality will be installed with every VIP.LEAN app requiring read and /or write access to the databases.
Under the menu point: Manage apps > VIP.LEAN ETL FOR REPORTING > Database Connections you can create, edit, and delete the database connections:

Field

Type

Description

Please select your database version.

Connection URL

String

When you click in this field a configuration URL will be recommended. Please enter the URL without any user or password information. See attached pictures below this table.
Oracle URL:
jdbc:oracle:thin@<host>:<post>:<sid> or
jdbc:oracle:thin:@//<host>:<port>/<service name>

Postgres URL:
jdbc:postgresql://<host>:<post>/<database>

Please ask your ETL admin for the correct URL.

Username

String

Database username provided by the DB Admin.

Password

String

Database password provided by the DB Admin.

Max. Pool Size

Number

Number of open connections to be used by the ETL for Reporting app to accelerate the DB read and write actions. When you increase this value, please make sure the required hardware resources are available.

Please test your connection before you save the connection. In case you receive an error message, please contact your DB admin to analyze the root cause (Network connection error, User and password are wrong, Connection URL is wrong …).

Once the connection is saved, it can be used by the app for further actions.

Please note: In the case where you use the DB connection actively for read or write actions, any subsequent change to the database parameters could lead to major errors. If you want to migrate your ETL for Reporting App to another ETL connection, please create first a second DB connection and migrate the Data ETL Rules to this connection.
