In this task of the rolling upgrade, you upgrade the execution stacks.
Before you begin
Note: The testing and simulation feature is not part of the rolling upgrade.
- Back up the client web applications.
- Install Operational Decision Manager for z/OS® V8.8.0.
Procedure
- Stop each zRule
Execution Server for z/OS V8.7 instance and
start the new zRule
Execution Server for z/OS V8.8.0 instances.
Each zRule
Execution Server for z/OS V8.8.0 instance is now connected to the
Rule Execution Server console V8.8.0.
- Optional: If the Rule Execution Server console is deployed as a
Java™ Enterprise Edition archive (EAR) on an application server
that is associated with an execution unit (XU) resource adapter, you must upgrade this XU resource
adapter when the Rule Execution Server console is
upgraded.
Stop and restart your application server after the XU resource adapter is upgraded.
Note: Skip this step if you are using a Tomcat server.
- If you have rule sessions in custom decision services, upgrade them.
- Upgrade hosted transparent decision services (HTDS) from V8.7 to V8.8.0.
Results
All execution stacks are upgraded to V8.8.0.
What to do next

Execution Server for z/OS client
