DB2 LUW 8.2.7 FP14 Red Hat AS2.1

(w/ thanks to Chris Eaton for the cool scripts)

I did this:
 create view DB2$MON_BP
 as select * from table(snapshot_BP('',-1)) as sntable;

then this:
  create view db2$vn_bphitratio as
  with bpsnap as (
  select  bp_name,
        float(pool_data_p_reads) as dp_read,
        float(pool_data_l_reads) as dl_read,
        float(pool_index_p_reads) as ip_read,
        float(pool_index_l_reads) as il_read
  from db2$mon_bp )
  select bp_name,
        dec((1 - (dp_read / dl_read))*100,4,1) as "Data Hit Ratio",
        dec((1 - (ip_read / il_read))*100,4,1) as "Index Hit Ratio"
  from bpsnap ;

Now, I get this:
  db2 => select * from oltp.db2$vn_bphitratio
  SQL1476N  The current transaction was rolled back because of error
"-801".  SQLSTATE=40506
  db2 =>

-801 is a divide by zero error.  My DB CFG DFT_SQLMATHWARN *is* set to
YES for this database. My BUFFERPOOL monitor is also ON.

Any ideas?

TIA
