Thanks, but how do you actually set that parameter ? I;ve have tried and the ASM instance does not seem to like it.

Thanks, but i cant get that far, as to set that parameter I need ASM up. But it will not start. So I have tried setting a text pfile with this parameter and this is message I get:

ORA-15021: parameter "_disable_interface_checking" is not valid in asm instance
