Hello,
Is anyonw aware of performace issues related to setting too many OEM (9.2.0.1) events ???

At the site that I am currently at, they have the following events set on all production databases. The frequenct for ALL these events is 5 minutes

probe
tablespace_full
max_extents
process_limit
session_limit

For one thing I am noticing that OEM does not use bind variables (go figure !!!), so if there are a 100 sessions I see 100 statements with the only diff. being sid = ???? . Also if there are say a 100 tablespaces again, there are a 100 statements in the shared pool with the tablespace name being the only difference.

In my mind , setting the above events at the frequency specified can cause performance problems, especially if it is a very active database. IS that accurate ?? If so, are there any notes / white papers about this.

Thanks,

Sunny
