Restarting Application Engine Programs

A key feature of Application Engine is its built-in checkpoint and restart capabilities. If a program step terminates abnormally or fails, you can restart the request from the last successful checkpoint or from the step immediately preceding the step that failed. You restart the program from the process request page.

This section provides an overview of restart and discusses how to:

• Determine when to use restart.

• Control abnormal terminations.

• Restart Application Engine programs.

• Start Application Engine programs from the beginning.

• Enable and disable restart.
