Program Execution - the Job Launcher

A session refers to an execution of a single application, that means, any executable. Examples of sessions are Hull Extract Scheme, Hull Parts List and Ppanparts.

The environment refers to all the environment variables listed in the environment table. The environment table specific for AVEVA Marine is separated from Windows system and user variables.

Sessions together with their corresponding input- and output parameters are called Jobs. A job file refers to an instance of a specific job. A session that is executed has a corresponding job file that contains information about the application, the input/output parameters, date of execution Job files are considered as temporary; that means, they hold no actual data, but only information about the parameters of that specific job. They are stored in a subdirectory called jobs below the directory given by the Windows environment variable %PDMSWK%.

In practice, job files are invisible to the end user and are used for example, by the Log Viewer to view input/output parameters and to follow up the execution status.
