Config and environment setup questions.

Question

This environment is all on a Solaris 9 server. Any input would be greatly
appreciated.
Apache error with WebLogic proxy plug-in, used Red Hat rpm.
[Tue Jul  1 10:31:15 2003] [warn] Loaded DSO modules/mod_wl.so uses plain
Apache 1.3 API, this module might crash under EAPI! (please recompile it
with -DEAPI)
What exactly does this mean? Should I move up to version 2.0 or would I
still have the same problem? Is there no way around compiling Apache again?
Also, Do I need to have WebLogic installed on the Apache proxy server? Could
I just take the mod_wl.so and copy it over onto the proxy server and follow
the regular procedures? If not can this be shared via NFS? How is it usually
done? I also entered replication group names, but cannot get any failover
capabilities. Is there anywhere else where I need to define these groups
other than the console. I'm trying to use the same .war used for the lab
during training.
-Dweblogic.management.discover=true (in startWebLogic.sh under my domain)
is giving me the following results for servers that are supposed to be
running.
UNKNOWN for a managed instance
FAILED_MIGRATABLE for 3 cluster nodes
This process also seems to take a very long time.
Able to start all these instance from the console but not if I let the
discovery process take it's course. The managed instance encounters no
errors. The cluster nodes get the following:

Is there any documentation regarding the use of a CVS repository for
development in conjunction with BEA deployments? For that matter any type of
reading the admin might find helpful when planning the development
deployment procedures. Thanks.

Jim,
If you already have a working application and just need to read/write a few tags I would look into DataSockets
http://www.ni.com/white-paper/3224/en/
Take a look at the example "Monitor OPC Items with DataSocket.vi" Under Industry Applications > Process Control.
