Working with Operator

Sessions

Session, step, tasks

A session is an execution (of a scenario, an interface, a package or a procedure, ...) undertaken by an execution agent. A session is made up of steps which are themselves made up of tasks.

A step is the unit of execution found between a task and a session. It corresponds to a step in a package or in a scenario. When executing an interface or a single variable, for example, a session has only one session step.

The task is the smallest execution unit. It corresponds to a procedure command in a KM, a procedure, assignment of a variable, etc

Status

A Session, step or task always has a status.

There are six possible status values:

When terminated, a session takes the status of the last executed step (Done or Error). When terminated, the step, takes the status of the last executed task (Except if the task returned a Warning. In this case, the step takes the status Done)

Handling Errors

To analyze an error:

  1. In the Operator tree view, identify the session, the step and the task in error.

  2. Double click the Error marker on the task. The task window opens:

Managing the Log

Oracle Data Integrator provides several solutions for managing your log data:

Scenarios

To run a scenario from Operator:

  1. Select the required scenario in the Scenarios view of Operator.

  2. Right click and select Execute.

  3. Select the Context and the required Agent (for execution by a client station, choose the option Local (no agent)).

  4. Click OK.

Oracle Data Integrator has created and launched an execution session when the message Session started is displayed. You can monitor the execution of the session in the log.

Before running a scenario, you need to have the scenario generated from Designer or imported from a file.

To delete a scenario:

  1. Right click the scenario and select Delete.

  2. Click OK to confirm the deletion.

  3. Specify whether to delete linked sessions or not. A linked session is one that was created by executing the scenario.

  4. Click OK.
