Manually, by executing the DSN_XMLVALIDATE built-in function when you INSERT a document into an XML column or UPDATE a document in an XML column. If you perform XML schema validation using DB2, you need to set up an XML Schema Repository. A DB2 for z/OS XML schema repository (XSR) is a set of DB2 tables where you can store XML schemas.
