The REPL tool was built against ICS running on OCI Classic. As this is no longer available the tool has been withdrawn
Oracle A Team
Earlier in 2017, the Oracle A-Team released a Python library that abstracts the ICS REST API to make some management tasks that you may wish to perform easier. For example, identifying a set of integrations and activating or deactivating them, or simply importing and exporting them. In this Definitive Tip, we will look at the REPL tool and its benefits. The REPL tool can be downloaded here.
Getting setup on Windows at least is a little fiddly as you need to install Python and then depending upon your version of Python update the installer and retrieve a number of additional libraries. REPL itself is available here.
