Oracle : Ошибка ORA-09924

"Can't spawn process - core dump directory not created properly"
*Cause: ORACLE was unable to spawn a background process because the
directory that holds the core dumps produced by ORACLE processes
in the event of exceptions was not created properly.
*Action: Examine the directory pointed to by the initialization
parameter "core_dump_dest". Make sure that all of the
following is true:
1. The directory exists.
2. The name indeed points to a directory, and is not a file.
3. The directory is accessible and writable to the ORACLE user.
