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?

remnode
remnode(8) System Manager's Manual remnode(8)
Name
remnode - remove one or more entries from the nodes database
Syntax
/etc/remnode [ node ]
Description
For each given node argument, deletes the corresponding node entry (or entries) from the nodes database. The nodes database is the one used
by DECnet. The node is either the node address or the node name for each node entry that you want to delete. Note, you can specify more
than one node argument in a single command.
A node address is a decimal integer in the range of 1 to 1023 for single area networks, or has the format a.n for multiarea networks, where
a is the network area number (a decimal integer in the range of 2 to 63) and n is the node number (a decimal integer in the range of 1 to
1023).
A node name can be from one to six alphanumeric characters, including at least one letter.
Examples
This command removes the entries for nodes 44.70 and Mynode from the nodes database:
# /etc/remnode 44.70 mynode <RET>
This command removes the entry for node lttwi from the nodes database:
# /etc/remnode lttwi <RET>
