Home -> Community -> Mailing Lists -> Oracle-L -> About having a large SGA for a DataWarehouse
At my site we'll be migrating a [currently very small 20GB] Corporate
DataWarehouse
from 32-bit 8.1.7 Solaris to 32-bit 9i Linux. It will grow rapidly with
Manufacturing Datamarts
to probably 500GB in a year.
Some of the DataMart teams are pushing for a very large SGA while I would
rather have a
large PGA_AGGREGATE_TARGET [not using 10g and Automatic Memory Management]
My rebuttal was :
We must consider how large we really need the SGA. A too large SGA
[assuming that it is not too large as to cause excessive Paging and begin
Swapping at the OS level]
can result in :
Comments / Recommendations / Corrections from this list, please ?
