Introduction:
As a good practice, we need to clean up and remove unnecessary and unwanted files from the MDS repository, whenever there is a major change in the composites / wsdl / xsd's or if you decide to create a new partition or renaming the default partition to some new name.
With every deployment / import of the metadata artifacts a new document version will be created in the MDS. This means that redeploying an updated WSDL or XSD into the MDS does not delete the previous version of the document. This will end up in ORA MDS errors.
