ORA-00444，ORA-07446故障排查

phenomenon

startup

ORA-00444: background process “MMAN” failed while starting

ORA-07446: sdnfy: bad value ” for parameter .

Problem

The path to bdump,adump or udump does not exist. Oracle itself does not create any path if a path does not exist. So, you have to change the value of user_dump_dest in the initialize parameter.

Solution

If you use pfile to start your database then edit the pfile with any editor (for example vi on unix) and either change the location of user_dump_dest or remove the parameter user_dump_dest from pfile. And then perform. startup.
