DB2 server for VSE an VM V7.5

I don't know why because I should know better by now but I still feel disappointed by this announcement ... again. DB2 has evolved enormously the last couple of years, that is DB2 for Windows, Linux, Unix and z/OS. Not so for DB2 for VSE and VM. I don't know whether I have many readers who are familiar with the z/OS ànd the VM/VSE versions of DB2. I know this is arguable but regarding functionality I tend to compare DB2 V7 for VM/VSE with DB2 V3 for z/OS. As far as I remember, DB2 V3 for z/OS was not a very favourable version as many customers went straight from V2.3 (via V3) to V4. Unfortunately V7 for VM/VSE is the latest version with (as we see now) no immediate improvement in sight. To show you what I mean here's the 'At a Glance' section from both the V7.4 announcement :

IBM DB2 Server for VSE and VM V7.4 delivers a solid base on which businesses can build on demand solutions.

  • Newly designed Data Propagator Q Capture function delivers powerful relational database that enables business intelligence solutions
  • Two-tier and three-tier solutions available
  • Scalable and highly available for demanding 24 x 7 environment
  • Member of DB2 family of products, which is available on all major platforms in the industry

Planned availability date: September 17, 2004

and the V7.5 announcement :

IBM DB2 Server for VSE and VM V7.5 delivers a solid base on which businesses can build on demand solutions. New in V7.5:

  • Newly designed client only feature enables you to buy just the Client Edition of the product.
  • Two-tier and three-tier solutions available.
  • Scalable and very available for demanding 24 x 7 environment.
  • Member of DB2 family of products, which is available on all major platforms in the industry.

Planned availability date: November 30, 2007

Not that many new features for a new release after more than 3 years !
As far as I can see the only significant new feature for this release is the new DB2 Runtime only Client editions for VM and VSE features. With these "you can purchase and use only the DB2 client, without having to pay for the database server. The Client Edition comes with some enhanced features such as bind file support and reduced Distributed Relational Database Architecture (DRDA) code path length, that will help them connect to data servers with greater ease and better performance". I think this message is loud and clear : move away from DB2 server for VM/VSE towards "data servers with greater ease and better performance" (mainly pointing towards DB2 for zLinux) and just run a client version on VM/VSE to preserve your previous investments on the platform.
Correct me if I'm wrong !
