5.3 Uninstalling a Single API Gateway

If you have only one API Gateway, uninstalling the API Gateway is the same as uninstalling Secure API Manager. For more information, see Uninstalling Secure API Manager. If you have clustered Secure API Manager and have multiple API Gateways, you can uninstall a single API Gateway without uninstalling Secure API Manager. You uninstall a single API Gateway if technical support recommend it or if you upgrade to a newer version of Secure API Manager. Some upgrade scenarios require that you deploy a new API Gateway with the new version, and then delete an old API Gateway. This way your system is always up and available to users when you perform an upgrade.

To uninstall a single API Gateway:

  1. Delete the API Gateway object.

    1. Log in to the Administration Console as an administrator.

    2. On the Dashboard, click the API Gateway cluster that contains the API Gateway that you want to delete.

    3. In the upper right corner of the API Gateway, click Actions.

    4. Click Delete, then click OK to confirm the deletion of the API Gateway object.

      IMPORTANT:As long as you have more than one API Gateway, the APIs that have been created in Secure API Manager are not deleted when you uninstall one API Gateway. However, if you delete your only API Gateway, all APIs are deleted.

  2. (Conditional) Power off and delete the Secure API Manager appliance from VMware. For more information, see Delete a Virtual Machine.

  3. (Conditional) If you are using the Docker deployment, run the uninstall script on each node in the cluster for the Docker deployment using the following command:

    ./sapim-node-uninstall.sh

    NOTE:The uninstall script is located in the sapim-install-2.2.x.tar.gz file.

  4. (Conditional) If you clustered Secure API Manager, remove the configuration information for the Secure API Manager deployments from the L4 switch.
