Zoomdata Version

Enabling the Real Time Sales Demo Source

A demo data source called Real Time Sales (RTS) is included as part of the Zoomdata installation package. This data generator simulates a real-time data stream; allowing users to interact with and explore Zoomdata's capabilities without the need to connect to a data source. However, this demo source, by default, is not available in the Zoomdata Client and must be manually activated. This article walks you through how to enable and disable the demo source.

A known issue with real-time streaming sources such as this demo source exists. If such sources are left enabled for an extended period of time, 'Out of Memory' errors may occur in the Zoomdata Server. To avoid this problem, disable such sources when not in use.

Preparations

To enable the Real Time Sales demo source, use an automated script that activates the demo source in the Zoomdata Client. This script, labeled create-rts.sh , is included as part of the installation package. However, the script needs to be run from the Linux prompt, so administrative access to your Linux server is necessary.

RTS is one of the components that is installed in your server as part of the Zoomdata installation process . However, if an alternative installation method was used to manually install each Zoomdata component, you should first confirm whether the RTS package was included during the installation efforts.

More specifically, running the automated RTS script will do the following (in the Zoomdata Client):

  1. Add the RTS connector server details in the Zoomdata Client (using port 8108).
  2. Define the connection type for the RTS demo source.
  3. Create the connection and generate the RTS icon in the Data Source page (as shown in Figure 3).

Set Up the Real Time Sales Demo Source

To set up the RTS demo source, take the following steps:

  1. Log out of the Zoomdata Client and close the browser window.
  2. Access the Linux prompt and log into your Zoomdata Server (via Secure Shell or SSH).
  3. From your Linux prompt, run the RTS script:
sudo /opt/zoomdata/lib/create-rts.sh -a admin: YourAdminPassword -s supervisor: YourSupervisorPassword ​​

Enabling RTS After Upgrading Zoomdata

If you are upgrading your Zoomdata Server to the current release version, that version's RTS demo source is deleted during the process and the current version is installed. You need to activate RTS following the same steps outlined above.

Disable the Real Time Sales Demo Data Source

To disable the Real Time Sales demo source, do the following:

  • Log in using the Supervisor credential
  • Select the Connectors tab
  • Go to the Connection Types section and locate the RTS source under Connection Type Name
  • Clear the checkbox in the Enabled column (as shown in Figure 4)
