after servererror trigger

Hello

I would like to ask you about after servererror trigger. I wrote trigger as below:

CREATE OR REPLACE TRIGGER notification_error

after servererror on database

declare

   d_sender varchar2(30) := ora_database_name;

   d_user varchar2(30) :=ora_login_user;

   d_rcp varchar2(100) := ' test';

   d_mailhost VARCHAR2(30) := 'test';

   d_mail_conn utl_smtp.connection;

   d_terminal VARCHAR2(30) :=userenv('terminal');

   d_current_nr_error number := ora_server_error(1);

   ora_server_error_msg varchar2(100);

BEGIN   if d_current_nr_error between 01800 and 02231

                or d_current_nr_error  in (09291,16014)

   then

     ora_server_error_msg := SQLERRM(-d_current_nr_error);

     d_mail_conn := utl_smtp.open_connection(d_mailhost);

     utl_smtp.helo(d_mail_conn, d_mailhost );

     utl_smtp.mail(d_mail_conn, d_sender);

     utl_smtp.rcpt(d_mail_conn, d_rcp);

     utl_smtp.open_data(d_mail_conn);

     utl_smtp.write_data(d_mail_conn, utl_tcp.CRLF || 'From: ' || ora_database_name);

     utl_smtp.write_data(d_mail_conn, utl_tcp.CRLF || 'Subject: ' || ora_server_error_msg);

     utl_smtp.write_data(d_mail_conn, utl_tcp.CRLF || 'User: ' || ora_login_user);

     utl_smtp.write_data(d_mail_conn, utl_tcp.CRLF || 'Terminal: ' || d_terminal);

     utl_smtp.write_data(d_mail_conn, utl_tcp.CRLF || 'Date: ' || to_char(sysdate, 'RRRR-MM-RR HH24:MI:SS') );

     utl_smtp.close_data(d_mail_conn);

     utl_smtp.quit(d_mail_conn);

  end if;

I do not know how to intercept background ORA error example "ORA-01652: unable to extend temp segment by 512 in tablespace TEMP" or

"ORA-9291 invalid device specified for archive destination "

Could you explain me how to do this?

Thanks for help
