What are Maintenance Packs and when are they applied?
Environment:
Maintenance Packs (previously known as Service Packs)
Oracle B2C Service Release and Maintenance Schedule
All supported versions
Resolution:
Oracle issues maintenance packs to enhance the product release cycle of Oracle B2C Service. Maintenance packs deliver code fixes and performance improvements without the need to perform a full upgrade. For more information about other update types, please see Answer ID 2525: Oracle B2C Service - Product Release Updates.
See also Support Notifications for important service notifications relating to system updates.
Maintenance Pack Contents
Each maintenance pack includes a comprehensive set of fixes and improvements produced during its release cycle, as well as fixes from previous maintenance packs for the same major release. For example, the 20C February Maintenance Pack includes several new fixes in addition to all fixes provided in the 20C January Maintenance Pack.
Fixes and updates contained in each maintenance pack are published in the maintenance pack release notes.
- To view information about fixes that have been applied to your site, expand the section below for your site's version and select the maintenance pack you would like review the notes for.
- To view what version and maintenance pack your site is running, select the File option in the upper left of the console, then Help > About.
- This information is also available from Answer ID 5168: Documentation for Oracle Service by following the link for your version and referring to the Maintenance Pack Release Notes section.
NOTE: Maintenance pack release notes do not include references to fixes associated with known security vulnerabilities.
Maintenance packs do not generally include new features, schema changes, or changes to customer-facing user interfaces and APIs. Maintenance packs also will not change the look and feel of your site. The application of these updates is not expected to result in downtime or reduced functionality.
