How to find the contents of proc from top command

Question

I had a doubt related to how to find the contents of a procedure or the statements from the PID displayed in top command if it can be done from TOAD or
sqlplus. If we can find out the details from top like:-
21211 oracle 16 0 3228 1012 764 R 0 0.0 0:07.68 top
1 root 16 0 1732 552 472 S 0 0.0 0:01.29 init
say, what is the process with PID 21211 and 1 are doing?
I hope, my question is clear.
Please, help in solving the doubt.
regards
