Online steering means to visualize the current state of an application which includes application data and/or performance
data, and to modify data in the application. Thus, in online steering the application as well as the steering tool must concurrently
access and modify the same data at run time. In this paper a new model for online steering is presented which models the mechanism
of online steering as access to a distributed shared memory. The integrity requirements of the steered application are analyzed.
The integrity can be ensured through an appropriate consistency model. Finally, the online steering system RMOST is presented
which is based on the distributed shared memory model and can be used to steer Grid jobs from the High Energy Physics experiment
