Archive logs for an instance may be archived by another active instance in the
following situations:
1. The 'alter system archive log all' command was issued manually without
specifying the thread parameter. Manual archiving is performed by the user
process that issues the archiving command; it is not performed by the
instance's ARCH process. The redo log files are archived to the destination
of the instance to which the user is connected.
2. Parallel server can force a log switch for an instance that fails to
archive its online redo log files for some period of time, either because
the instance has not generated many redo entries or because the instance
has shutdown. This prevents a thread from remaining unarchived for too
long. After an instance has shutdown, another instance can force a log
switch for that instance so that its current redo log can be archived.
Either situation can result in archive logs being written to the destination
of the active instance. [/B]
