after recovering your data, check if the LogPages which are still
on the LogVolume are sufficient for a restart. You can do this with
the dbmcli-command db_restartinfo. If the database is restartable,
the you do not need any log-backup. Rather you should execute a restart
until by using the command 
	db_online -u yyyymmdd hhmmss
