UnknownHostException trying to connect to WebService

Hi, I have to connect to a WebService and get the following error when running my client-program.

I know that the host exists so that can't be the error (?).
It would be great if anybody could give me a hint how to solve the problem - I'm running out of ideas.
(Please help a newbie!)

Why not simply create a virtual column yourself, instead of relying on an implicit functionality?
Then you're in control of the name of the virtual column.

create table t1(n number);
alter table t1
add (abs_n generated always as (abs (n)))
/
create index i1 on t1(abs_n);

Is the name of that hidden virtual column stable? In other words, when I upgrade from Oracle 18c to the latest version, will the SYS_NC00002$ name change?
The name is derived from internal_column_id. It changes when the preceding columns are dropped or index recreated.

A common recommendation for function-based indexes which solves the problem of column naming and repeating the potentially complex expression being indexed is to create a view containing the expression as a column and then query the view instead. Whether this is suitable in your case will depend a little on how your environment is maintained and used.

3rd party software is preventing the OP from using a proper Virtual Column.
I'm wondering - if that column was HIDDEN, would the SW work?

User_1871

@mike-kutz Yes, I think a hidden virtual column would work. It's a good idea, thanks.
What does SW mean?
