This document covers the following topics related to zaps and your use of Adabas Cluster Services:
Please be sure to check the Knowledge Center in Software AG's Empower (https://empower.softwareag.com) web site for any cluster-related Adabas zaps (APvrsnnn) when you install Adabas Cluster Services.
Usually, zaps for components of Adabas Cluster Services (Adabas nuclei, the SVCCLU component of the Adabas SVC, the ADACOM task) can be applied and made active one component at a time. That is, individual components can be shut down, have the zap applied, and be brought up again without ever shutting down the entire cluster. This is the default method of applying zaps, which is in effect if the zap description does not explicitly state otherwise.
In some cases, it may be possible that applying and activating a zap one component at a time would introduce erroneous behavior in the components that have not yet been zapped. If this is the case for a zap, it will be clearly indicated in the zap description, and instructions will be given for how to apply and activate the zap properly.
