server Migration unix to redhat linux


We have digital alpha unix server and ms dos workstation, all the server and client communication through PATHWORK (software package from digital).
Now we have plan to migrate digital alpha unix server to redhat linux server(only server).
Here we are using c/c++ programing , file syatem for server and workstation for c/c++ programs.
There is no program modification server side and workstation side, just server os level migration.

Question:
1)After migrate unix to redhat linux server, how to communicate the client? Should I use for pathwork software?


Regards..

Sorry, going to have to provide details, before anyone can help.

If you're just changing the server, and your code already is working, not sure what else you think you have to do. "How to communicate"? Since you don't give any details about your OLD setup, what programs, protocols, etc., how can we tell you?

Provide details about your programs, what they're doing, and where you're having problems, and we can try to help. Otherwise, you can contact Redhat support, since you're paying for it with your RedHat enterprise subscription...

OK....

more details...
1)in our old setup hardware was obsolete, no support from vendor forthcoming march 2010.

2) so that we are move unix system to linux system(redhat).

3) we are using c/c++ programing and file system(no database) in server side and c/c++ programing in client side.

4) server and cilent communication through PATHWORK.6 (from digital corporation).

5) server os having alpha unix and client os msdos 6.2


question..
1) is there any possible for unix to redhat linux os?
2)if yes how to communicate server to client ?

Note:
1) we never want to change appliacation and os level client side
2) we don't have any subcription redhat linux, because we are in planning mode unix to redhat linux. if once confirmed with redhat linux, we will go for further.
3) pls provide usefull weblink , if anything related above..

Free replacement for Red Hat (RHEL) is CentOS. They are binary compatible so what efver works on CentOS, it will work on RHEL, but you will not get paid support, so for production use you will want to buy RHEL. There should be fairy easy upgrade path to RHEl, or you just delete CentOS and install RHEL once you are done testing.

Getting software compiled for Alpha to work on Intel processors could pose a problem. Are you able to recompile it?. Or will you have to run
RHEL version for newer Alpha station? This the main question. I have not seen CentOS (nor RHEL) for Alpha platform other then 4.8.

And can you get PATHWORK license for new platform? Or will it be only solution to just stock up with Digital's parts and try to work with different platform? Maybe Thin client approach, not having OS on clients at all?

Still no useful details. You said your program was written in C/C++ to start, but that doesn't say ANYTHING about how it works. Pathwork is from Digital, no longer supported.

Question 1: Yes, you can run C/C++ code on Linux. Copy it over, compile it, and run it.
Question 2: "How to communicate", depends on your program. If you used Pathwork to do it, you'll have to rewrite your code to use something current. Again, you don't say anything about what your application does, what it communicates with, over what protocol, so it's hard to say.

Sorry, not an option. You'll have to change the application. Pathwork is a Digital product, not supported by anything BUT Digital hardware/OS. Upgrade.

Then use CentOS instead. It's RedHat, but community supported.

Please spell out your words. And since this is a custom application, how can there be any 'weblink' to direct you to?? This is your application. We can help you work through porting problems when you recompile/ugrade, but there's not much else we can do.

Actually, given that DEC was bought by Compaq, then they merged with HP, and HP can run RHEL (eg http://h18000.www1.hp.com/products/s.../howtobuy.html), I'd phone HP and ask for the best migration method/advice on PATHWORKS replacement etc.
