How to recovery CBK files under different operating systems?

The short answer is that you cannot restore a CBK from AIX (a big-endian system) onto Windows (a little-endian system). You would need to restore the CBK on another location on AIX (or another big-endian system), and copy the CACHE.DAT to the Windows system, where you can run the cvendian utility to convert the endianness. Note that this comes directly from that page of documentation:

Note:

This utility does not work for backup and journal files. You must restore databases on a platform of the same endian, move the restored databases to the different endian platform, and then use the cvendian utility to convert the databases.
