We are planning to install next configuration: two application servers, Oracle data on external disks reachable from both servers and HACMP. Servers will be on AIX 5L, Oracle 9i will be used and my question is: which HACMP version is required (or desired).
Thanks for help.

Hello!
My state of knowledge is, that the version of HACMP only depends on the
the AIX-Level (incl. Maintancence Level).
I guess you are going to create a takeover construct, where appplications
are to taken from failed nodes.
From HACMP's point of view the apllication servers are realized by executing scripts.
To make the long story short :
The latest HACMP-Version for AIX 5L
is V5.1

Greetings

Hi,

We are currently using HACMP E.S 4.5 With AIX 5L and Oracle 9i.

We have two servers and external disks reachable from both servers. We decided to have all SW (Baan and Oracle) and data on external disks. Is this scenario possible? Could be any problem with validation? I suppose, we need to validate network management and HACMP as well.

Thanks in advance for answers.

What about the rootvg's ?
Remember, the brandfile(s) reside(s) in
the directory /.brand.
Seems, that nobody knows about the
exact constitution of the validation code.
But definitely it depends on the system
hardware.
As i previously mentioned, in a takeover
szenario the license daemon will also be
swapped to another hardware. In that
case you will get the demo situation
automatically and that is the problem.
Are you planning to do so?

My idea is to put both servers names in $BSE/lib/licence6.1, validate network and HACMP and result must be brand files on both servers. My question is: is it enough to have only $BSE/bin directory on internal disk or complete Baan SW have to be on internal disk (on both servers)?

Don't you plan to use IPAT ?

As far as I know there is no IPAT anticipated. HACMP will install another person, so I don't know too much about. My duty is to prepare Baan (install and validate) for planed scenario. This person advise me to have all SW on external disks, but I am afraid that in this case it will be not possible to validate Baan properly.

Hmm! Do we have a communication problem?

But don't worry,

The external disks themselves are not the problem, provided that they are supported for HACMP.

The baan validation problem depends
on your HACMP-Konfiguration.

No IPAT means you can use the Cluster and network functions in the validation.
But you have to install an complete baan
application on both nodes.
In case of takeover you have to tell HACMP how to deactivate the "local" baan of the second node except the licence management. The idea of moving
$BSE/bin to a internal filesystem
seems useful.
In case of takeover you can link the local $BSE/bin to the Baan environment, which has been taken over.

In our system baan and oracle runs on different machines and their softwares are on external disk (fastT 700) . RootVG's are on internal disks and both has a /.brand directory.
We don't have any licence problem when we takeover. I do not know how it is licenced by our cunsultant but if I can learn it from him I will post it here.
