Particularly lock files are not a problem - each database has own lock file, and certainly same database can't be accessed with 2 engines supporting different major ODS. But we have a number of other shared files (trace, mapping change notification, may be else). I see that trace name includes ODS version name (fb12_trace). The only problem that opened database is ODS13 ;) I.e. that issue worth to be checked and fixed. ------------------------------------------------------------------------------ What NetFlow Analyzer can do for you?
