Can't open View->DBA Menu in SQL Developer (Oracle 12C Standard Edition Installed)

Question

I have installed Oracle 12C Standard Edition. Everything works fine there. I have also connected the Oracle SQL Developer Client 4.0. From that I can access the tables, indexes etc.

I am trying to see the tablespace details from SQL Developer Client by clicking the View -> DBA menu. By clicking this menu, nothing is getting opened.

Through EM I can able to see those. But I want to see through SQL developer.

I am not sure, whether I need to do any settings, so that the View -> DBA menu can be opened.

Attached Screenshot for reference:

Here I am selecting the DBA option under View Menu

But I don't see any DBA related window.

Answer 1

I faced same problem, solved by: Windows->reset windows to factory settings. After that everything worked fine
