I just got this weird oracle error message upon attempting to start up my Oracle XE:
ORA-44412: Invalid ACL: Cyclic ACL inheritance is not allowedIt happened after setting SGA_TARGET to 1GB in the SPFILE, on a windows XP pc where probably the amount of virtual memory was not sufficient to support this request.
I could open the database normally by using a backup PFILE with a lower SGA_TARGET value.
See a previous topic for instructions on how to restore a valid SPFILE.
