HA Cluster solution for Linux - which one to use?
Hi all experts,
I need your kind suggestions or feedback on choice of clustering software for red hat linux nodes running certain applications which I need to make highly available.
Minimum requirement is 2 nodes; all nodes shall be active-active running distinct applications e.g. node 1 runs application ABC and node 2 runs application PQR, node 1 is back up node for PQR and node 2 for ABC. Node 1 and node 2 do not have any shared storage required, they access back end database which is protected by Oracle's dataguard.
I need to have cost-effective HA with minimum downtime. There are various HA solutions available in market - SteelEye, Veritas Cluster, Red Hat cluster suite, IBM HACMP etc. and I have almost narrowed down to Red Hat Cluster(for it being cheaper) vs Veritas (for it being feature rich).
Any experiences with clustering? Any pros and cons of these two cluster software (with references would be appreciated) would be of great help?

load(8) System Manager's Manual load(8)
Name
load - down-line load software to a target node
Syntax
/etc/load [ node ]
Description
The command loads software to an unattended target node. The target node is loaded by the host that executes the command.
The command requires the identification of the service circuit over which the load is performed, the Ethernet hardware address of the tar-
get node, and the service password needed to gain access to the target. This information is included in the nodes database entry for the
target node. A node entry is defined with the command. For further information, see The node is the name or address of the target node.
A node name consists of from one to six alphanumeric characters. For single networks, a node address consists of a decimal integer
(1-1023). For multiple networks, a node address consist of two decimal integers (n.n), where the first indicates the network number
(1-63), and the second indicates the node address (1-1023).
Options
-p Uses the specified service and password (next arguments) in accessing the target node. You can omit a target node's service and pass-
word from the nodes database for security reasons, but you must then specify the service and password in the command line by using the
option.
Examples
# /etc/load bangor -p 130fe
This command causes node to be loaded by the ULTRIX host node executing the command. The ULTRIX host uses the load files specified in the
nodes database entry for node to perform the load.
