Whizkid79,

The biggest difference between DB2 V7 and V8 is the Architectural Requirements. DB2 V8 will run ONLY on a zSeries machine and on a operating system of z/OS v1.3 or higher.

DB2 V8 will Not support old hardware nor will it support OS/390. Additionally, DB2 customers must migrate to V7 before converting to V8. There will be no IBM-supported capability to jump from V6 (or an older version) directly to V8 without first migrating to V7.

DB2 V8 will fully utilize the 64-bit addressing DB2 could have up to 16 hexabytes of virtual storage addressability to be used by a single DB2 address space.So, DB2 V8 will exploit 64 bits and, over time, that will make things faster and more efficient.

Also Many other limitation have been eliminated like large object names, expanded partitioning, new types of partitioned indexes, improved partition management and more.
