Ok, I'll admit my ignorance. What the heck does "1 row" mean? It can't mean the
row length, or you'll end up with a negative PCT_USED.

Hi Bambang,
Analyze the table and you'll find the average row length in
USER_TABLES.AVG_ROW_LEN. Subtract 90 bytes from the block size before
expressing that as a percentage and round it up. Also, the formula
should be PCT_USED = 100 - (PCT_FREE + 1 row). There are scripts on the
Ixora web site that do this sort of stuff.

Dear Listers,
I've download a presentation talking about Calculating PCT_USED .
the formula is quite simple :
PCT_USED + PCT_FREE < 100
PCT_USED = PCT_FREE + 1 row size
but I have no idea to calculate the size of 1 row in a table .
is there anyone who knows to calculate it ?
or any alternative formula to calculate PCT_USED ?
Thanks a lot in advance : )
