I am curious as to how a failed statspack job can cause this ?
Christo,

you're probably the only person that will be interested in this, but I
included the callstack of the first trace file from the j00n processes
inline below.
And if not for production monitoring, where would you run statspack :)
This is where I insert some attempt at humor mentioning the Heisenberg
Uncertainty Principle. This generated 75 trace files since yesterday
morning. Preventing any sessions from being created pretty much falls
outside of non-destructive testing.

Binary Stack Dump ---------------------

The Ora-600 lookup tool didn't find the callstack to be very interesting.
I wonder if I can make that my home page in Metalink?

Since this is testing I'll hold off until next week to open an iTAR.

A hanganalyze did not yet complete.
The job still appears to be in progress, so its not completely fubared.
A trace file is being generated by a backround job that appears to be
a statspack snapshot.
Is it just me, or is statspack in 10g not something that is meant for
usage anymore?
(wide open hole for soliciting signatures for Niall's post concerning ASH).
I've seen a perfstat.statspack.snap collide with AMM causing major
amounts of grief in 10.1.0.4 on win32 at least 3 separate times
(disabled both now) and have seen at least 2 other posters here
complain about shared_pool latching issues related to that
combination.

This is not how I planned to spend my afternoon.
I had hoped to sneak out to a theater to catch DOOM (the movie) - not
doom, return of the ora-600.

thanks.

A failed background job executing a statspack.snap was the root cause.

datapump exports now run fine without issue.

The fix was brutally simple and did not require downloading a patch or
regression testing:

SQL> @?/rdbms/admin/spdrop.sql;

I've concluded that scheduled statspack snapshots just plain do not
belong in a production database, at least for win32 10.1.0.4, even
with statistics_level='BASIC'; and AMM not in use.
