What to monitor during stress test

We want to monitor our Oracle server during a test where we submit an unusually high amount of data to the server.  On a server side, what are some of the key resources that we should monitor?  On the application side, the same.  Are there any tools out there that can be used to collect key data from Oracle?  We are using Red Hat Enterprise 5 as our OS.

If you are licensed for it, I suggest AWR and ADDM through Enterprise Manager.

I suppose monitoring the application depends on things like:  What is it written in?

Apart from the above, If you want to monitor an oracle database or unix or linix box, there are plenty of tools/utilities/resources available which you can get by search from google or any search engine.

For example, if you specific about the application monitoring - then monitoring the weblogic/app server connections, database connections to see whether they are hitting the max number of allowed connections etc can be done to avoid app not crashing/becoming unresponsive/throwing errors etc.

What kind of app is yours and what is that used for ? If we have some more information, then we can give more responses/feedback related to that one and also we can try to keep that precise with respect to the context of your question.

it's always the queries, well ... in 98% of the cases it is

if you are uploading tons of data, then i would assume you have thought of parallel inserts
check the tables INITRANS parameter if you do this (default it's at 2)


next to that the report as slightwv suggested

or do it yourself ... way cheaper

every x seconds (we do this every second)
query the v$sql table sorted by disk_reads and buffer_gets
the queries  with the highest disk_reads and buffer_gets require attention

v$sql sorted by the field executions will give you the queries executed most
> these top ones are usually design flaws or some of them can be buffered

If you want to go the 'free' way, I suggest Statspack.  It will do most of what is posted above and a lot more.

Oracle is trying to get away from this but it is still around.

This is a 9i doc but it should still apply up through 11gR2 (Haven't checked 12c).

And what are you trying to learn or demonstrate with this test?  Are you trying to be prepared for an increase in data or transaction volume that you know (or hope) may happen someday soon?  Are you trying to demonstrate that your current server and storage hardware is adequate or inadequate?  What kind of application is this: transaction processing, data warehouse, a mix, etc.?  Is this a purchased application (if so, which one) or is this a custom application?  Who set up the permformance-related parameters in your Oracle parameter file?  Was that someone with a lot of experience managing Oracle on Linux for this kind of application?  What kind of storage system do you have: NAS, SAN, etc.?    Does it include some SDDs?  Does your database use Oracle's ASM feature?

Unless you can help us understand what some of the business problems are that you are trying to solve, it is very difficult for us to give you specific help.

Some Experts post that they are available for contract jobs in their profiles.
