Accroding to this article, I can install OEM Sequalink server (comes with IBM WAS CD) without having to enter a registration key.

Does it mean that if I follow the instruction to install it (add /v"IPE=NO" after the setup command), the Sequalink server will not expire?

I didn't know this two weeks ago so I simply double-clicked the setup.exe and I ended up getting a Sequalink server that will expire in 30 days.

Thanks...
