Hi all,

I am having trouble identifying the optimum SGA and PGA settings for a data-warehouse style application.

We have a 10g rel2 database running on a windows server 2003. The server RAM is 2G, with 2 CPU's. Nothing else to note is running on this server.

The application is running 7 similtaneous scheduled jobs, each of which is extracting data using a dblink from a progress database using datadirect odbc driver. The dblink\odbc\progress part of the equation is working fine.

current settings are:
SGA_MAX_SIZE=1577M
PGA_AGGREGATE_TARGET=300M
SGA_TARGET=1098M

OEM addm is advising increasing SGA_TARGET to 1834M - which obviously will not work (1834 >1577) and I dont want to increase SGA_MAX_SIZE above (2000M - 20%) = 1600M

Any advice much appreciated !.

Advisor says one value, you say (and I agree) you can't set this, so stay to your maximum.
