1.) Save your current SQL connection xml file located in windows 10: C:\Users\"youruseraccount"\AppData\Roaming\SQL Developer\systemXXXXX\o.jdeveloper.db.connection.xxxxxx

2.)Now delete your SQL Developer Folder and sqldeveloper folder located in: C:\Users\"youruseraccount"\AppData\Roaming\

3.)Now delete the main sqldeveloper folder containing the actual SQL developer application files.This would be located wherever you initially unzipped the SQLDeveloper download.

4.)Download the latest version of SQL Developer and unzip wherever you like.

5.)Launch SQL developer and specify your JDK location.

6.)Copy your connections xml file to your roaming SQL Developer directory here: C:\Users\"youruseraccount"\AppData\Roaming\SQL Developer\systemXXXXXX)\o.jdeveloper.db.connection.xxxxxx

7.)Launch SQL Developer and your DBA view should now be available after selecting view -> DBA
