This document covers the procedure and the tools for applying patches for Sentinel products.

General information


The Patch Generator requires a running Rhino with the released software that will be patched. It takes as its main input the SLEE DUs or SLEE Jars (SLEE deployable unit) to be patched. The tool will query the live Rhino to capture the dependencies on services and other components. With that information it will generate a file that captures the dependencies and a set of actions to be taken in a precise order.

The Patch Runner tool is responsible for applying the patch. It takes as input the patch for the Rhino client for the product to be patched. The tool will run a checklist to assert that the system is in the expected state. Checks include component names, version and the dependency tree. If the system is in a state that can be patched, the tool will install the new components according to the list of actions generated by the Patch Generator.
