Bob,
I can't answer your questions directly, but I think, Tim Gorman's book - Essential Oracle8i Data Warehousing can.

Re your signature:
I just struggled today with an error message, It took me quite a while to realize why Oracle was telling me that the values keyword was missing. (An over-simplified version of the statement follows) Are Oracle error messages not keeping up with the code?

SQL> Begin
  2 Merge into emp e
  3 Using (select *
  4 from emp_temp) t
  5 on (e.empno = t.empno)
  6 when matched then

  7      Update  set
  8          e.hiredate = t.hiredate
  9    when not matched then
 10        Insert into emp  (empno, hiredate)
 11        values  (t.empno, t.hiredate);

12 End;
13 /

      values  (t.empno, t.hiredate);
     *

ERROR at line 11:
ORA-06550: line 10, column 14:
PL/SQL: ORA-00926: missing VALUES keyword

Subject: Info on VLDB/DW

Good Morning All, I was hoping someone here can point me to pertinent documents which address (DW). I know there are tons of online docs via google or metalink but was wondering if people her had their own favorites. Im particullary interested in nutshell concepts of:

1 reasonable maximum datafile sizes & physical disk striping 2 getting data from prod to dw
3 various partitioning
4 stratigies for backup + recovery

Thanks
Bob
