Installing
Review this section for information about installing the WebSphere Commerce product, associated maintenance, and WebSphere Commerce enhancements.
Installing maintenance
WebSphere Commerce maintenance includes installing fix packs, interim fixes (APARs), and cumulative interim fixes.
Interim fixes and cumulative interim fixes
A WebSphere Commerce interim fix (iFix) is a software patch that contains fixes for one or more APARs. A WebSphere Commerce cumulative iFix is a comprehensive collection of interim fixes for a specific release. Both types of fixes are installed with the WebSphere Commerce Update Installer (UPDI).
Additional steps for member or session management-related interim fixes
Some interim fixes include changes that affect login or session management. After you install the fix, you might need to complete additional steps to enable the fix on your environment.
