poncejua, thanks for the that, it answers the ORA_SHUTDOWN part of the question: TRUE or FALSE I guess, with a datatype of REG_EXPAND_SZ

But I still need to know about the WORKINGSET parameters.

On oracle instance startup Shared Global area, buffer cache and
redo buffers are reserved and committed. Because only a small no
of these are touched they are not in oracle's working set.

Oracle must contend equeally with other processes and wil have its
working set trimmed if other processes are faulting.

Pre_page_sga does not help if oracle has to contend for its
working set . hence the other two parameters to manipulate oracle's
working set.

ORA_WORKINGSETMAX and ORA_WORKINGSETMIN are
measured in megabytes.

The most useful of these is ORA_WORKINGSETMIN which prevents the working
set of ORacle processes from dropping below the threshold until the instance is
shutdown, only leaving the stub oraclexx.exe in the end.

IF used in combination with pre_page_SGA which touches all of the
SGA pages at ORacle startup, the working set will start above the minimum threshold
and not drop below.

If ORA_WORKINGSETMIN is used in isolation, then once the working set rises above the threshold

And
ORA_SHUTDOWN can be set to true/false , false is the default.

Hope this helps.

This is just in addition to the answer above -
The  line which reads -
if ora_workingsetmin is used in isolation  - is completed as
if ora_workingsetmin is used in isolation , then once the working set
rises above the threshold , it will not drop below.

Also set these parameters in
HKEY_LOCAL_MACHINE -> SOFTWARE -> ORACLE in the
registry

Almost there, the datatype is REG_SZ ?

And what are the default values?

OK! Here we go ...

The default is "FALSE"

and the data values you could set are like 20 for 20MB and
30 for 30MB.

It is a string value.

OK, so i now know how to adjust the workingset size, but I still don't know what the default values for the MAX and MIN are, or are they calculated based on memory size?

Sorry to string this one out, but I omitted this detail from the initial question in error. (I knew what I wanted!!!)

This is my understanding of these parameters.

The workingsetmax is not very useful, but when set would go as high as the total size of the shared_pool, buffer_cache and redo_buffers , which would be the same as setting pre_page_sga. This may not be optimal as other processes could be suffering because of this - especially if the database has a varying work load.

The workingsetmin which is more useful, when set let's say to 20MB, when the system gets loaded, the oracle process retains its memory pages and doesn't fall below the 20MB.

I think that when these parameters are not set by default they are set to false, Oracle's
working set is not fixed and it contends with every other process to get  its memory requirement,  and at instance startup only a few of the memory pages are touched .  And  if other processes are faulting oracle's memory pages / working set could get trimmed and oracle's memory pages could get paged out.

If you don't set , then oracle and NT handle the working set for Oracle and does not reserve any memory pages for oracle and could get paged out if other processes are faulting.

If set then the oracle's working set doesn't go below ORA_WORKINGSETMIN.
