Manually Installing the Database Engines

MariaDB and MySQL

MongoDB

MariaDB and MySQL

Databases are installed on the Discovery Server to collect, analyze, and work with the data received from the robots. Nintex Process Discovery uses four application databases managed by one or the other database engine:

Database	Database engine
PD application database #1 (data segregated by Team)	MySQL 8.0.11 (or higher)
PD application database #2 (data aggregated for all Teams)
Process Library database
User Management platform database

You can choose manually install MariaDB 10.3.7 (or higher) or MySQL 8.0.11 (or higher).

See MariaDB and MySQL – Manual installation

MongoDB

Nintex Process Discovery uses MongoDB to store user actions in collections:

1. Raw data collections:

Images + metadata recorded by Discovery Robots (segregated by team)

Collection prefix - pd-rawdata-${TEAM_GUID}

2. Masked images:

Only if masking is enabled (segregated by team)

Collection prefix - pd-masking-rawdata-${TEAM_GUID}

Connecting to remote MongoDB

You can configure the connection to MongoDB before or after you install Process Discovery.
