Not able to catch Exception

Question

While passing SQLERRM into a variable. Exception is not being caught. Am I missing something?
create or replace procedure schema1.proc1 (p_sequence number)
v_status_flag varchar2(1000);
begin
v_status_flag := 'INITIAL';
begin
schema2.proc2 (p_sequence, v_status_flag);
exception
when others then
v_status_flag := 'ERROR--';
end;
insert into temp1(status)
values (v_status_flag);
end;
select * from temp1;
ERROR--
create or replace procedure schema1.proc1 (p_sequence number)
v_status_flag varchar2(1000);
begin
v_status_flag := 'INITIAL';
begin
schema2.proc2 (p_sequence, v_status_flag);
exception
when others then
v_status_flag := 'Error--'|| SQLERRM;
end;
insert into temp1(status)
values (v_status_flag);
end;
select * from temp1;
INITIAL

Thanks Manik, sorry I missed commit.No, the problem isn't that you missed Commit. The actual problem lies in the way you are handling exceptions.
This way, you will never understand if there was any exception during execution of your stored program. Needless to say, exceptions must be propogated to the Parent callers after logging appropriate Error messages in your tables.
Below is a sample way of doing so:
create or replace procedure logError(err_code in number, err_msg in varchar2)
is
declare
  pragma autonomous_transaction;
begin
  insert into error_table(err_code, err_msg);
  commit;
end;
create or replace procedure schema1.proc1 (p_sequence number)
v_status_flag varchar2(1000);
begin
  v_status_flag := 'INITIAL';
    begin
      schema2.proc2 (p_sequence, v_status_flag);
    exception
    when others then
      log_errors(sqlerrcode, sqlerrm);
      raise;
    end;
end;
/Similar exception handling needs to be performed in Proc2 as well, as this ensures the exception is Caught, Logged and then propogated further in calling hierarchy.
I hope this helps understanding Exception handling. Also read a nice demonstration and explanation by BluShadow on Exception handling {message:id=2718301}
