We often need to produce record counts of the particular schema.
 Create this procedure, change it as per yr requirements.
right now I am inserting rowcounts in a table with timestamp.
  create table table_count(T_owner varchar2(50), T_tablename varchar2(50),
T_rows number);

create or replace procedure count_records is
v_ct number := 0 ;
v_sqlcode number := 0 ;
v_stmt varchar2(90) ;
cursor c_tbl is
select owner, table_name
from sys.dba_tables
where owner = 'SYSADM';

r_tbl c_tbl%rowtype;
open c_tbl;
fetch c_tbl into r_tbl;
exit when c_tbl%notfound;
v_stmt := 'select count(*) from '||r_tbl.owner||'.'||r_tbl.table_name;
execute immediate v_stmt into v_ct;
v_sqlcode := SQLCODE;
if v_sqlcode = 0
-- An insert into a row count history table should probably be here
then dbms_output.put_line('Table '||r_tbl.owner||'.'||
' count is '||to_char(v_ct,'999999999990')

insert into table_count values(r_tbl.owner,r_tbl.table_name,v_ct);

else dbms_output.put_line('Bad return code'||v_sqlcode||
' on select of '||r_tbl.owner||
end if;
end loop;
close c_tbl;
