Here is something to consider. A new trend is developing (and being
promoted by big SW companies like SAP) is Tier consolidation whereby OS
instances are reduced by placing the App server(s) on the same server as
the DB. Since most servers are only running less than 20% in peak time,
this makes a lot of sense - you just need to ensure things like workload
mgmt are in place to ensure one process does not do something silly and
impact other processes. No big deal as this has been a practice on many
other platforms for years (including OpenVMS).

And how things used to on Unix. Remember, it *is* a timesharing OS, just like VMS.

You not only eliminate OS instances, but also network latency issues, as
well as provide a common OS environment for doing batch jobs.

True. Depending on how beefy your server is, and how parsimonious the CFO is. Since it's being rewritten in Oracle and hosted on a SAN, moving the batch cycle to another machine (a blade, maybe) shouldn't be "that much" of a chore if the database+batch machine gets burdened.

Which is what has happened on 2 of our VMS clusters. But one of them is /finally/ migrating to a GS1280. Yay!!! I guess the string of crashes attributed to ancient hardware pried open the purse strings.

I guess the falling price of used Alpha kit made it palatable.

Now, ask your Dev team that is hot for Linux how they plan to address
this growing trend in the future i.e. a common platform for the App
server, db and batch environment.

See, that's the beauty of client-server. If it's written in a network-centric manner, the apps don't care where they are.

And since x86 Gbit NICs cost probably the same as 100Mb NICs that are VMS-qualified, and 4Gbit Linux-qualified HBAs are also readily available, making the database server a bandwidth demon is pretty darned simple.

And the forever-growing power of x86-64 h/w means that if "they" do decide to keep it host-based, regular guts swaps are pretty darned cheap.

Want to bet they will say they need a separate server for each
Application and DB?

Want to bet they have likely not even thought or included the pricing
for converting and migrating their batch requirements (some environments
run hundreds of jobs per day)

If *management* did not factor that into the contract with our clients (who wanted off of VMS), then shame on them, not the developers.

or their many supporting Operational
applications with associated custom code developed over many years that

You must think us flaming idiots.

now must also change as part of the new platform?

They may be "just" developers, but they're not stupid.

A dozen or so of the lead developers have been with the project 8 years or more (in that time, 2 of them have had the time to segue from "Indian consultants wanting to return in 5 years" to married-
with-children naturalized citizens).
