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 search-related interim fixes
Some interim fixes include changes to search indexes, search directory templates, or WebSphere Commerce search configuration files. After you install the fix, you might need to complete additional steps to enable the fix on your environment.
Enabling interim fix JR57304
Interim fix JR57304 adds the ability to disable data cache invalidation for delta di-buildindex runs.

Enabling interim fix JR57304

About this task

By default, the di-buildindex command (DataImportProcessorMain) registers the following cache invalidation entries in the CACHEIVL table regardless of any delta changes.

WCT+CATGRPREL+?
WCT+CATGRPDESC+?
WCT+CATGROUP+?
WCT+SRCHATTR+?

This default setting can cause high CPU usage on the search server when the system makes frequent catalog updates.

To disable these data cache invalidations, use the parameter -skipInvalidation true when you run the di-buildindex command.

Example

di-buildindex.sh -instance instance_name -masterCatalogId masterCatalogId -fullbuild false -skipInvalidation true
