Oracle tries to fit SGA in 1 segment, if it doesn't oracle searches for
contiguous segment, else tries for non-contiguous segment.
Thanks and Regards,

Subject: relation shared pool elements phys mem
Hi,
=20
I have an undersized development box where my main problem is the memory
=20
I regularly get
ERROR:
ORA-04031: unable to allocate 48 bytes of shared memory ("large
pool","unknown
object","session heap","UGA heap pool")
I have a shortage of phys memory. I remember that the complete SGA
should
fit into=20
1 memory segment. Is this correct and does this imply also this should
be in
phys memory also?
I have a swapfile that is not used extensively.
=20
If I downsize my sga, should i decrease the size of the memory segments
as
well to profit from the=20
decrease ?
=20
Regards,
