Had a look on Metalink - looks like its a bug in 9iR2 when using it to create a DB with datafiles over 2GB

From looking at the bug report its not fixed till 10G:

This seems to be JAVA jarring/unjarring limitation (In 9.2, we use Java compression to copy seed databases). Looks like Zip entries have a limit of 2 GB. Still investigating if there any possible work arounds. . This problem will not be seem in 10i, since we use RMAN instead of JAVA compression for cloning databases in DBCA.
