= System Properties
:imagesdir: ../..

These system properties can overwrite default properties of the application,
for example, by passing `-Doptaweb.generator.zoneId="America/New_York"` to Spring Boot.
These system properties might also be exposed as OpenShift template parameters.

* *optaweb.generator.timeZoneId*:
The time zone ID for the automatically generated tenants.
For example `America/New_York`.
This defaults to the system default Zone ID.

* *optaweb.generator.initial.data*:
What data to initially put in the database.
Supported values are: `EMPTY` (no data) and `DEMO_DATA` (several tenants of various sizes).
This defaults to `DEMO_DATA`
