To apply a PowerExchange hotfix, run the z/OS Installation Assistant.
The hotfix must be for the existing PowerExchange version, such as 9.6.1 HotFix 3 for PowerExchange 9.6.1. Otherwise, complete an upgrade to get the software for the PowerExchange version with the latest hotfix.
Hotfixes provide a subset of the PowerExchange software that you install on top of an existing PowerExchange environment. When you install a hotfix, PowerExchange does not create new data libraries, such as those containing data maps, capture registrations, and extraction maps. As a result, you do not need to migrate the contents of these data sets, which simplifies the installation process.
When you apply a hotfix, you cannot add new data sources to an existing PowerExchange environment. To add new data sources, you must complete a full installation or an upgrade.
Because PowerExchange hotfixes are cumulative, install only the latest available hotfix.
