Managing jobs

36 Sybase IQ ETL 4.1

If you have multiple data streams it is highly advisable to design a project for

each data stream so that all components within a project are connected to each

other. By following this design guideline, it is easy control the data streams by

connecting the projects to form a job process flow.

Managing jobs

A job lets you easily set up the powerful control flows for one or multiple

projects. Although Sybase IQ ETL projects require some kind of user

interaction during simulation or execution, a Sybase IQ ETL job can be

scheduled to run without any user interaction.

Depending on the success or failure of a project within a job, you can control

the job execution.

Job components

A job consists at least one of the following components:

• A Start component

• A Project component

• A Success component

Figure 4-2 shows an example of a job with one Start component, one Project

component, and one Success component.

Figure 4-2: A Job with the minimum components

A job can be extended to include:

• Multiple projects in sequential or parallel order

• Multiple synchronizers

• Multiple Success and Error components
