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.

Solution 1

Selecting the View->DBA menu item displays the "DBA" panel, on the left side of the SQL Developer window and somewhere below the "Connections" panel; the exact placement may vary a bit depending on which other panels you have displayed:

You then need to add a connection in that window' if you click the green plus sign you can choose an existing connection to add to this panel. Once you've done that you can expand the sections to see the tablespaces:

Solution 2

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

Solution 3

goto Menu of the Sql Developer windows-->Reset the Windows to Factory Settings

and then goto view menu ----> click DBA

it works.(Version 17.2.0.188)
