Hello All,
I am running Oracle 10.1.0.4 on Win 2003 and over the past couple of weeks I have noticed that I have been generating trace files and I am not sure how it started or how to stop it. I am not sure if it was enabled after installing the October 2005 Security patch but I have turned off sql_trace, trace_enabled and timed_statistics. The questions I have are:

1) Does this has anything to do with the DBMS_MONITOR feature?
2) Is it alright to have this type of tracing files generated?
3) My servers performance has deteriorated. Would this be a part of the problem?
3) How do I stop it?

I have done the following:
SQL> select * from dba_enabled_traces;

TRACE_TYPE
---------------------
PRIMARY_ID
----------------------------------------------------------------
QUALIFIER_ID1
------------------------------------------------
QUALIFIER_ID2 WAITS BINDS INSTANCE_NAME
-------------------------------- ----- ----- ----------------
SERVICE
SYS$USERS

TRUE FALSE

The trace file generated has the follow information:
