Home -> Community -> Usenet -> c.d.o.server -> Automatic index generation & little tunning
Hi !!
Can someone explain under What circunstances are index automatically
generated ?
I know that, when I create a table with PK, automatically is generated
an index for this table,
but... has the same result a Fk ? or a NOT NULL constraint ?
And related with index and tunning, I think that default Storage
parameters and
increase parameters are in general good, not allways.
For a example, if in table A I've lots of inserts and updates, what
are the best
parameters ? (PCTFREE, MINEXTENTS, PCTINCREASE...)
And if in table B are only 1 insert and lots of selects ? (by a PK with its own index)
Thank's in advance !
