Step 1: Download the latest TIBCO Activation Service product from the TIBCO Software Downloads site: https://www.tibco.com/downloads.

Step 2: Review the TIBCO Activation Service product documentation at https://docs.tibco.com/products/tibco-activation-service-1-0-0.

Step 3: Install and configure the TIBCO Activation Service. Follow the installation and configuration instructions provided in the TIBCO Activation Service documentation.

TIBCO Activation Service is only supported on Linux. Check the readme file for details about the supported platforms.

Installation packages: TIB_tibco-activation_1.0.0_linux_x86_64.zip
unzip TIB_tibco-activation_1.0.0_linux_x86_64.zip
cd TIB_tibco-activation_1.0.0

Install using one of these commands, depending on the Linux platform variant. (You can run the commands without 'sudo' if you have the privileges.)

For Red Hat, Centos , Fedora:
sudo yum install -y rpm/*.rpm 

or
Sudo dnf install -y rpm/*.rpm

Step 4: Activate TIBCO Rendezvous® 8.8.0.

You need to get the host identifier (hostid) for the linux machine where the TIBCO Activation Service runs. Hostid is a unique identifier for the instance of the activation server. It is used to bind a generated license to the instance of TIBCO Activation Service.  A license bound to a specific instance of TIBCO Activation Service can only be uploaded to that instance.

Use following command to get hostid:
tib-activate server hostids
