About this task

You can set your preferences for debug and Job executions in Talend Studio. To do so:

From the menu bar, click Window > Preferences to display the Preferences dialog box.
Expand the Talend node and click Run/Debug to display the relevant view.

Set the parameters according to your needs.

In the Talend client configuration area, you can define the execution options to be used by default:

Execution options
Option	Description
Stats port range	Specify a range for the ports used for generating statistics, in particular, if the ports defined by default are used by other applications.
Trace port range	Specify a range for the ports used for generating traces, in particular, if the ports defined by default are used by other applications.

In the Job Run VM arguments list, you can define the parameter of your current JVM according to your needs. The default parameters -Xms256M and -Xmx1024M correspond respectively to the minimal and maximal memory capacities reserved for your Job executions.
If you want to use some JVM parameters for only a specific Job execution, for example if you want to display the execution result for this specific Job in Japanese, you need open this Job's Run view and then in the Run view, configure the advanced execution settings to define the corresponding parameters.

For further information about the advanced execution settings of a specific Job, see Setting advanced execution settings.
