Modifying Application Properties

Prerequisites

To be able to modify a property in the SAP NetWeaver Administrator, it has to be an online modifiable

property, that is, to be flagged onlinemodifiable = true .

Using the Config Tool you can change both offline and online modifiable properties.

Recommendation

We recommend that you use the Config Tool for offline configuration only so that the consistency of the AS Java configuration throughout the cluster is preserved.

Context

You can change particular properties of your application using two different tools:

Config Tool for offline configuration. For the changes to take effect, restart the AS Java.
SAP NetWeaver Administrator for online configuration. The changes take effect immediately.

Recommendation
We highly recommend that you modify application properties using the above listed tools and not programmatically.

Procedure

To modify a property using the Config Tool: Modifying Service, Manager or Application Properties .
To modify a property using the SAP NetWeaver Administrator: Java System Properties .
