setting Event dynamically

Hi all,
I'm running into some nasty ora 600. not really a show stopper but and Oracle says setting an event would suppress it. This is a prod box. My question is whether this event can be set dynamically?

event = "10262 trace name context forever, level 4000"

Thanks
Tony

By "dinamically" you mean "without a db cycle" ??? If so : I don´t know specifically for 10262, BUT for all events what I needed until today, yes, I could to do an :

sql> Alter session set events 'nnn trace name context nnn, level x';

OR use oradebug, inside sqlplus, as :

/u1/app/oracle>sqlplus /nolog

Thnks,
It appears that those "events" with "=" sign cannot be set dynamically.

Nonsense, the "=" is just part of the syntax to set an event inside an initfile, ANY event setted in initfiles need it, this is NOT the stopper here..... The sintax showed is right, BOTH for oradebug and for ALTER SESSION (and you can use ALTER SYSTEM with the same syntax), but the point is : some events MUST be setted before the database is completely open (at startup-time), so such events works ONLY in initfiles... As I said, I do not use 10262, so I don´t know if it works out of the initfile, YOU will test it, in your test db, and (of course!!!) with Oracle Support help...
