In my PL/SQL script, I have requirement to test the connectivity of remote data. Normally, in OS shell, we use command tnsping. Is there any command in SQL or PL/SQL so that I can test connectivity.
Basically, I am getting some data using database link. I want my script to execute immediately. If remote database is available then I want to run query using database link. If remote database is unavailable then I want to skip the getting of data using database link. So, this is the reason why I am looking for.
Kindly guide me for proper way. So, that my script does not hang in case of unavailability of remote database.
I am using Oracle 12.1C.
