Deploying a Custom Feed Handler

Move custom feed handlers to your production environment by installing or updating.

To move a new feed handler to a new or existing production environment, use the installer:
1. Install the publisher API in the production environment.
2. Use the custom installer to complete the installation. Specify settings for your feed handler in the Publisher API configuration dialogs.
3. Copy the binary into the folder for the feed handler.
4. Configure the agent to start the feed handler.
5. Start the agent.
6. Start the feed handler from the OpsConsole.
Note: If you want to add a new feed handler to an existing environment, Sybase recommends using the installer to install the Publisher API in the directory where the new feed handler should reside. Using the installer rather than just copying files has these benefits:
- Installer prompts for configuration file settings. Using the installer ensures that your publisher.xml settings correctly match settings entered during installation, and used by various components.
- Installer creates a directory for the agent and does most of its configuration, again from values entered into the installer. All you need to do is specify the command to start the feed handler from the agent.
To update an existing feed handler:
1. From the OpsConsole, shut down the running feed handler.
2. Update the binary for the feed handler.
3. Use the OpsConsole to configure the publisher, and add or edit data stream channels.
4. Start the feed handler from the OpsConsole.
