>I have also tried the same scenario on a CDB as sysdba and 184.108.40.206 as sysdba running the same sql.
You do not say what the result was. I am assuming it worked on CDB and 220.127.116.11.
select * from v$database; -- works for me though there is a lot of formatting code between the database and the display.
If I can reproduce I can log a bug and work from the code in debug mode.
I want to reproduce and / or cut down where the issue might be:
1/Try other sqlplus or SQLDeveloper against PDB1
eg. SQLDeveloper 3.2.2 against PDB1 (if Production 3.2.2 does not work you can go through Oracle Support), 12c sqlplus against PDB1, or 18.104.22.168 sqlplus against PDB1
I listed out various SQLDeveloper worksheet/sqlplus emulation issues in a blog post SQLDeveloper Senior Member of Tech Staff blog: User check on sqldeveloper (worksheet) issue - I will add to it if there is significant interest.
2/Try to find out what part of v$database is causing the issue
try count(*), subsets of the columns, to_char() on any problem columns so more conversion is done on the database rather than SQLDeveloper
3/Try other user - system
(This is unlikely to be useful but worth a try if nothing else shows promise)
4/There is debugging/log information
e.g.Most serious java issues cause a message to the screen ('Java Stack Trace') if you start sqldeveloper from ide/sqldeveloper/bin from the command line
5/try as a different operating system user
in case your per user settings are corrupt. (This is pretty general advice not worksheet specific)
