Sun Solaris cluster , SUN Application server 9.1 clustering and failover configuration

Hi,

I'm required urgent to install / configure SUN Application server 9.1 clustering
with failover (ie this application will failover to the secondary server when the
primary server is down).

Q1 :
Kindly point me to a link/site or provide steps on how to install this (brand new install),
assuming Solaris 10 has been installed on both nodes

Q2 :
Is Sun Application server 9.1 free of charge and which DVD / CD on Solaris this is
found?  Let me know also a link / site to download it

Q3:
Do we install Sun App Server 3.1 on one server or on both servers?
If I install Sun App server 9.1, would I still need to install Sun clustering
solution or Sun App server 9.1 alone would have provided the high-availability
feature

Q4:
Short of installing Sun App server 9.1 or Sun's official clustering solution, I heard
there are Shell scripts that can be used as substitute to deliver high-availability
solution.  Any pointers or sample scripts are appreciated

Q5:
Is Sun App server 9.1 or Sun's HA solution free of charge or they're available
freely for distribution/public use

2 more items I'm asked by customer to deliver :

a) create Server1 and psi instances for domain :
   is Server1  referring to Domain1's of Sun Java App server?


b)Test failover of application when there's cluster failover :
    how do I go about doing this?

A3: You install two app servers. You do not need clustering to load balance HTTP (mind the session synch) DNS, SMTP
A4: App server handles load balancing itself, Clustering product requires startup/shutdown script for custom apps.
A5: No, but JBoss is free of charge
Aa: Domain is DNS domain(s) which is organized to serve same app(s) on all cluster servers
Ab: Switch off one node correctly, for more extreme test unplug one from network and cluster.

Thanks a lot Gheist.

So I have to choose between Sun HA cluster or  Sun Java Application server,
ie e don't install both, just one of them?

Do you happen to know if Sun Java Application Server requires a quorum
disk?  What about Sun HA cluster, does it require a quorum disk too?
Trying to choose between Application Server or HA cluster to see which
is simpler and easier to get going.  Both the T5120s run some sort of Java
applications in them.

Currently both the Sun T5120s are connected to an IBM DS4700 SAN :
can this shared SAN disk be used as quorum disk or we need another
chunk/LUN from this SAN to act as quorum disk.

Hoping for something simple that do not require quorum disk as the SAN
administrator is not there anymore.  Practically the whole tech support
team left and I'm called to chip in

HTTP session is a small thing and webservers handle it.
Cluster does start apps on one server when other apps go down.

Failover cluster is not a solution for WWW.

Pardon me, I'm rather slow-witted,

so are you recommending Sun Java application server,
& that Sun HA cluster is not a good option for providing
a high-availability webserver?


You may have replied but could you reply to the following again :

HTTP protocol is designed with HA in mind.
