# 3.28 – Using Java parameters

In some cases, the use of Java parameters during or before the start of SparkView is useful or necessary.\
Depending on the system, these must be entered as follows:

#### Windows
Enter the parameters in the SparkView control panel under the "Java" tab one below the other.

#### Linux/MacOS
Enter the parameters directly with the start command, e.g.
