Hi all, anyone know the logic behind GUID generation? we have been in situations where we see duplicate (yup) guid being generated by the system, a SR is open but no ETA. I have seen couple notes that this is well known to happen on AIX (we use that too), So the question is, 1. How the guids are generated (i mean i understand it uses time stamp and all but what other parameters are used) ? 2. what would cause it to generate dups ? this is for 11gr2 Best regards Raj
