Any chance to open a database which needs recovery in read-only mode? My attempts with dbeng -r lead to the error message that the database needs recovery and dbeng refuses to start. Recovery is no option as the database has a checksum problem in the checkpoint log :-( |

You cannot open a database which needs recovery in read-only mode. The recovery process makes changes to the database. |
So if the current database file is damaged, can't you go back to the last full backup and the current transaction log (and possibly intermediate TLs), in case those files are not damaged?
yes that is our last option, before that I would liked to run a dbvalid -s to check all checksums and see how much damaged has occurred
AFAIK read-only mode requires a valid database file and will fail in your case. (I assume dbeng -f against a copy of the database file will fail, as well.)
If the current database file is damaged but the current TL is OK, and there is a clear backup path, I would
Of course I do not know your requirements and recovery times so treat this as just my 2 cents.
(In case you except the server hardware to be questionable, well, then that would require a different doing...)
