When using CA Common Services/ENF (called ENF here) to record events in a production LPAR, having the system available is a great concern. However, in order to complete an upgrade of the CA Datacom/AD system (e.g. from version 12.0 to 14.0), ENF must be shut down.
How can we minimize the outage window while making this upgrade?
These instructions will apply to your CA Common Services/ENF environment and its MUF, whether using the ENFIMUF (internal MUF) or ENFXMUF (external MUF) configuration. Because we recommend that clients use the ENFIMUF configuration, this article will assume that perspective.
As with any upgrade of CA Datacom/AD to take the MUF from version 12.0 to version 14.0, you will do a new installation, and this will allocate all new files for the CA Datacom/AD product, but it will not allocate new files for your ENF database.
This can be a relatively easy upgrade, and you should incur only a minimal outage - there is no way to upgrade the CA Datacom/AD software without stopping ENF for a brief time. We would recommend you perform this upgrade during normal outage window, or at a time of low activity where you can shut down ENF for a minute or two.
Below is an overview of the process (the first 4 steps can be done at any time prior to your cutover):
