Sorry, I didnt know about problems to receive attached files, I am
resending it as just text
We have worked with VMS for a long time, but two years ago we installed a
new Unix system in a client server configuration with two DEC Alpha
2000-4/275 with two processors each one and 1 GB Ram: a database server
running Oracle and an application server running some ERP software (Baan or
Triton).
After a lot of performance problems, are working on a capacity planning
analysis.
We would appreciate your comments about how should be understand memory
usage, based upon the monitoring data we understand that::
Memory consumpted by all users is the "Active Memory"
When "Active Memory" usage is low, "Inactive Memory" also is low but always
is higher than "Active Memory" what is the relationship and diference
betwen "Active" and "Inactive" memories?
Memory usage, both Active and Inactive, seems to be the same no matter what
is the workload, we are comparing let say Monday vs Wednesday or Friday
when we have different workloads. It is true mainly on the Server, Why?
The "Wired Memory" usage is so high. Is it used by Triton or others
resident procesesses? Can it be reduced? is it adviceable?
What can we expect to happen if we reduce UBC size? who or what generates
UBC memory usage?
Attached you can read the memory usage reports, for both the client and the
server, samples are from Monday to Sunday and only from 09:30 Hrs to 12:30
Hrs that is our peak time.
Memory usage quantities is in number of pages, each page is 8,192 bytes
long.
The data base server has phisicaly 1024 Mb of Ram that equals 131,071
pages, while the clienthas 640 MB of Ram that equals 97,919 pages:
