You can use the SQLExecutor transformer to get information from the TAB table in the Oracle database (Select tabtype from TAB where TNAME = '@Value(fme_feature_type)'). This will show if the fetaure type is a VIEW or TABLE.

Optionally you can just filter out the views if the information can be found in feature type (e.i using V or VW for view in the feature type name) eventually try avoiding reading the views if the naming is consistent by using the Feature Type To Read parameter.

Hope this helps.
