Thanks Lex, I thought that if a parameter is documented (even if an _parameter), it was supported. So if it's not, I agree that it's not a good idea to set it unless explicitly suggested by Oracle support staff.

I do agree this one is pretty "harmless" but the above is true for any parameter that starts with an underscore, regardless how harmless it is. for one thing, these parameters are not tested as thoroughly as the documented ones. So if Oracle support wants to play it formal, they can refuse to help you because you are running Oracle in an unsupported configuration ... kind regards, Lex. ------------------------------------------------------------------ Steve Adams Seminar http://www.naturaljoin.nl/events/seminars.html ------------------------------------------------------------------ ------------------------------------------------------------------------------ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Radoulov, Dimitre Sent: Monday, July 18, 2005 15:43 To: Lex de Haan; 'oracle-l' Subject: Re: BIN$ objects (after media recovery) Hi Lex, I agree that this solution is drastic, but we monitor our production systems with BMC Patrol (with recyclebin the CPU is always on 100% because of the tablespace free space check). "if your database is properly sized ..." We are an outsourcing company: many clients, many sistem integrators, too much third party/custom code and load/functionality changing every day, it's really hard to size properly these systems. "to disable a nice feature in an unsupported/undocumented way ..." Why undocumented? See Note:265253.1: 10g Recyclebin Features And How To Disable it( _recyclebin ). Cheers Dimitre Radoulov
