event 44591
        The article at
	
http://orainternals.wordpress.com/2008/05/16/resolving-hw-enqueue-contention/
	
recommends setting event 44591 to improve performance for tables with BLOBS. We tried it and our performance improved.
	
My questions:
	
- Is it ok to set event 44591 in production env?
	
- How to check if event 44591 is arleady set on a system?
	
- The article above and tests we ran in Oracle 10. Do you know if the above applies to oracle 11?
Thanks,
Hisham
