Hello Lothar,
true, these lines are related to DBRM and are just a consequence of long parsing (CPU usage). However depending on your Oracle release you can easily troubleshoot why it takes so long to parse :)

See page 19 here ( http://www.soocs.de/public/talk/160616_DOAG_Regio_NUE_Identifying_Performance_Issues_Beyond_The_Oracle_Wait_Interface_PPT.pdf ) and you can use a script from Franck Pachot to parse the CBO output for better readability ( https://blog.dbi-services.com/cbo-parse-time-match-time-with-transformation/ ).
