Db2 12 function levels
New Db2 capabilities and enhancements are continuously delivered in a single maintenance stream as the code becomes ready. You can activate the new capabilities in a data sharing group or Db2 subsystem after a function level is delivered. A function level corresponds to a single PTF that enables the activation of a specific set of enhancements that shipped in previous prerequisite or co-requisite PTFs. The activation of a function level results in the activation of all lower function levels.
Many new capabilities and enhancements in Db2 12 are introduced when you activate new function levels. However, some continue to be available even before you activate function level 501 or higher. For more information, see Recent enhancements to Db2 12.
About function levels in Db2 12
A function level enables a particular set of new Db2 capabilities and enhancements that were previously delivered in the single continuous stream of Db2 code. It includes code that supports new capabilities, defect fixes, and preventive service items. Before you can use the new capabilities of a function level, you must activate the function level, or a higher function level. Activation of a function level implies activation of the capabilities that are introduced by all lower function levels.
