Uninstalling Teracloud® Streams

Use this procedure to remove the Teracloud® Streams product from your system.

Before you begin

To uninstall Teracloud® Streams, you must be the installation owner or have root authority.

Stop the applications, instances, and domains that are using the version of the product that you are uninstalling. For more information, see Stopping Teracloud® Streams applications, instances, and domains.

Enter the following command as user root to unregister the resource from the domain and stop the domain controller service on the resource:

  streamtool unregisterdomainhost -d domain-id --zkconnect host:port

The --zkconnect option specifies the name of one or more host and port pairs for the configured external ZooKeeper ensemble. If you specify multiple host and port pairs, separate each pair with a comma. This value is the external ZooKeeper connection string. To obtain this value, you can use the streamtool getzk command.
