RE: OEM Events

How often do YOU check these limits (tablespace utilisation, and "max extents")?

Once per day, somewhat less than every 10 minutes.

Sunny,

There is a whitepaper that I found available from:

www.csis.gvsu.edu/GeneralInfo/Oracle/em.920/a96675.pdf

This is the "Oracle Enterprise Manager Event Test Reference Manual Release 9.2.0" document..

I note two things in this document. For the "Tablespace Full" event, it's
"Recommended Frequency" is 30 seconds (!), though it contradicts itself by
saying:

"Note: Running the Tablespace Full event test may be a resource-intensive
operation.
Therefore, Oracle recommends running the Tablespace Full event test during off-peak periods."

It says the same thing with the "Maximum Extents" event as well, stating the
"Recommended Frequency" as 10 minutes (you can take that one back at
least),
whilst still stating:

"Note: Running the Maximum Extents event test may be a resource-intensive
operation. Therefore, Oracle recommends running the Maximum Extents event test during off-peak periods."

One last thing to consider, with all of these events set at 5 minute intervals - do they all the checks execute at the same time? How about monitoring the monitor, to see what kind of resources it really is chewing up? I wonder if you will start to see large spikes on five minute intervals
;)

Here's one for the list:

How often do YOU check these limits (tablespace utilisation, and "max extents")?
