The DB2-version is 22.214.171.1248. Source OS is Windows Vista, target is Windows 7. As I mentioned before, the Vista system is dead and thus the instance on which the database resided does not exist anymore.
I have retreived the database folder and files from the Vista system harddrive and I want to recreate this database from these files.
I am using a relocadedb.cfg file in which I have experimented a little. One version I have tried looked like this (I have consulted the DB2 online help as well as google):
Here is another one:
However, both these files render the same message (DBT1025N).
To me it seems like there is no way of using db2relocatedb for databases that no longer exist within a running db2 instance, but I might ofcourse be mistaken.
I'd try copying the files to the target system using exactly the same directory structure as in the old system. Assuming you have installed DB2 and created a new instance using all the same parameters as before, issuing CATALOG DB whatever ON C: might just work.
