Running a Project

Running a project automatically starts the project either on a local cluster or on another connected cluster, enabling you to upload data from a file, manually enter data, and view streams in that project.

Prerequisites

To run a project in a workspace other than the default, ensure that one or more connected workspaces are available.

Task

Select and open the .ccl file you want to run.
If no editors are open, pick a project to run.
To run the project, either:
- Click Run ESP Project in the main toolbar (in either the SAP Sybase ESP Authoring or the SAP Sybase ESP Run-Test perspective) to run the project in the default workspace, or,
- Click the drop-down arrow next to the Run ESP Project tool and choose Run ESP Project in Workspace. Then select the workspace where this project will run.
The project runs and shows results in SAP Sybase ESP Run-Test perspective.

Note: If you have run the project before and encounter an error stating that a failure occurred because the application already exists, this is because the project still exists on the server in a stopped state. To redeploy, remove the project from the SAP Sybase ESP Run-Test server view, and then restart the project from the SAP Sybase ESP Authoring perspective.

Server View
The Server View shows servers available for connecting and running projects.
Viewing a Stream
Stream View shows all of the events of an output stream and all of the retained events in an output window for the running project.
Controlling the Pulse Rate for Viewing a Stream
When a data stream contains few items with a high volume of changes, you can set a pulse rate so that changes are delivered periodically, in optimally coalesced blocks. For example, a stream containing three ticker symbols may generate thousands of updates every second. You can set the pulse period to control the frequency at which you receive updates when viewing the stream. If you set the pulse to refresh every 5 seconds, the subscription then delivers, at most, one updated record for each of the three symbols every five seconds.
Uploading Data to ESP Server
Use the File Upload tool to load event data from files into a running project. Normally used in testing a project. Date and time stamps in data loaded through the File Upload tool are assumed to be in the local timezone.
Manually Entering Data to a Stream
Manually create and publish an event as input to a stream or window. By default, date and time stamps in data loaded through the Manual Input tool are assumed to be in the local timezone. You can change this setting to use Universal Coordinated Time (UTC) through your Studio preferences.
