Linux application servers and HPUX database servers.

[Alex Lavrov]

Hi,

Most of our applications today run on 2 HPUX servers. One server is the application server (runs apache, java, oc4j, ias..), the second server is a database server (runs oracle).
Our company is now planing our consilidation project. Our idea is creating a "datacenter" in which HPUX servers run the databases (Oracle) and several Linux's run the application software.
I am interested to know if you have experiance with such architecture or any tips.
thanx.

I'd be glad to answer questions about our current architecture or our plan.

Hi Alex

how do you connect running appliactions on Linux with database on hpux server, In this case you should be running both database and applications on hp servers and their clients running on Linux m/c's

[Christopher Caldwell]

We've done exactly as you've suggested:
-Oracle on HP-UX in ServiceGuard
-App server on Linux in ServiceGuard
-App servers on Linux with load balanced front-end for "availability"

The biggest things we've noted is that RAMI doesn't seem to be a primary consideration in commercially vended/assembled hardware. They simply don't cook the hardware the same way (rendundant though-and-through). Even in the case of redundancy (e.g. multiple fiber cables on Linux), the system doesn't seemlessly fail - a la alternate path).

We you go to build RAMI into your system, you're probably better off using the front-end technique on Linux rather than try and N+1 design, since Linux and the hardware aren't quite there [yet].

You'll find that your hetergeneous technology makes for a nice mix of price and performance.

If you plan to use linux to run Oracle Application Server you only can on a supported version of linux such as "RedHat Advanced Server 2.1" or "SuSE SLES 7" which are old versions of linux and costs about 2000???. These are the only versions supported and other versions can cause a lot of problems.
I installed database and app server on two linux RH ADV.S. and works fine.
Now I'm trying to install Oracle Collaboration Suite on a RP5430 HP Server with only two disks not in RAID. Which storage do you use in your HP Servers?

We have a couple of RH7.3 servers running Oracle clients (Apache + mod_owa, Tomcat, cgi perl + DBD::Oracle) connecting to both Windows and HP-UX instrances of Oracle databases.

Clients talk to the hosts using OCI connections.

I recommend running Oracle9i client s/w on Linux, as in my experience it works much better than 8i.
