From ora_dump:<node>_<sid>_FG_ORACLE_000.TRC :

The trace file of the foreground process  starting the Instance contains these messages:

Changes

OpenVMS logicals had been created  in an attempt  to control whether a dump file would be created for pmon if the pmon process died.  The name of the logical was incorrect.

$ define /sys/exec ORA_<instance name>_PMON  false
