The first thing to try is (from SQL Developer's main toolbar): Window > Reset Windows To Factory Settings
If that does not work, then:
1) Export your connections
2) Rename your user settings folder for 4.2 (on Windows 10 that is %APPDATA%\SQL Developer\system220.127.116.11.089.1709) to something else
3) Restart SQL Developer and see if View > DBA works
4) Import your connections
Thankyou for the prompt answer
Window > Reset Windows To Factory Settings
will i lose my current set of connections ??
No, that is only a problem if you nuke the system18.104.22.168.089.1709 folder without exporting your connections first. Which is why everyone always suggests renaming the folder rather than deleting it.
Thanks the reset windows worked.
how would i export and import the connections anyway ???
also do you know how you can see dbms_jobs for a user in the DBA view or any other way ?
please start new threads for new topics/questions
Jeff is right, of course. But Google is your friend.
In recent SQL Developer releases, the export format changed from xml to json, but I believe the xml format is still supported for connection imports.
When I try and see DBA view in Sql Developer version 22.214.171.124.089 . . .
A terribly old version. My first suggestion would be to upgrade to the current 19.2.
