ORA-01089: immediate shutdown or close in progress - no operations are permitted
We can see above that MMON was first stopped. Then, strangely, the MMON start
was attempted. Since the database was already shutting down, MMON start got
ORA-01089. This error got then propagated to SQLPlus.
The dedicated server process trace confirms this and adds a bit more
information:

Could anybody guess the reason for MMON start in the course of the shutdown and
how to prevent it?
