Sybase must look at providing test environment like Oralce
does for "Oracle 10g RAC On Linux Using VMware Server".

Did you see the disclaimer in the introduction of the article? They describe
this only as a setup for testing the *installation* of RAC (which is indeed
pretty complex; ASE CE is much easier to install), and indicate this is not
efficient not production-ready.

your point being!

any idea if sybase plans on having the eval-ASE-CE or
something like that, in the near future?

I don't know that. I guess you'd need to talk to your Sybase sales contact
perwson for evaluation licenses.

The demo I ran at TW 2007

(http://s3.podiumsystems.com/sybase/techwave2007/wein.html)

was done on the same environment. VMware Server, Centos virtual
machines, VMware private networks, and VMware for shared storage. In
fact you could probably take the first half of that document (the VMware
/ OS setup) and follow the same instructions for getting ASE running.

One shortcoming I've found in this as a test environment is that you
can't "pull the plug" on the shared disks. With VMware you can
disconnect the network adapters which is great for testing cluster link
failure, but you can't disconnect the disk, which means you can't use
this environment to test what happens when one node in the cluster loses
its disk access. To get around this you could setup a software based
iscsi target on your host OS (such as IET - iscsi Enterprise Target) and
do shared storage via iscsi instead of VMware disks, creating a separate
host-only network in VMware for the iscsi traffic. Then you can use
VMware to pull the plug on that network. Two immediate downsides to
this: (1) it is a bit of a pain to setup that iscsi stuff since, in my
opinion, it is poorly documented and suffers from interoperability
problems; (2) you'll want to test storage disconnect handling on the
actual storage stack you intend to run in production. There is far more
variability on how the storage drivers react than in the network handling.

One more thing - Last I checked (and it may have changed in version 2)
VMware Server doesn't support SCSI-3 persistent group reservations,
which means you can't use this environment to test i/o fencing.
Unfortunately IET doesn't support this either. The latest Solaris iscsi
target software supposedly does, so you could setup a Solaris 10 x86
virtual machine and host the iscsi storage there, but then you get into
more interop issues with the linux iscsi initiators.

As Rob says, you'll need to contact Sybase sales to acquire the software.

"sybase"

Who are you ? can you identify yourself by something better than
