IBM PureData System for Analytics (Netezza) and Db2 user-defined extensions compatibility
If your Netezza® databases used user-defined functions (UDFs), user-defined aggregates (UDAs), or user-defined shared libraries and you want to run these objects in a Db2® environment, you must create new compiled source and register the objects by using Db2 processes.
For more information about using user-defined extensions with Db2 products, see Creating and managing user-defined extensions (UDXs).
For details about differences between Netezza and Db2 SQL that are related to user-defined extensions, see IBM PureData System for Analytics (Netezza) and Db2 SQL compatibility.
