Configure Cluster --load balancing.

[Nguyen Anh Tien]

Now i have 4 node (Just called: node1,node2,node3,node4) Cluster. 2 package. both of these package is on node1 and others node are stanby. In this model node1 is exhausted. Now i want to run 2package running on 4 node(or 2 node) concurrently.
Is there any way to balancing load on 4 node?

There is no way that I know of to have a MC/SG package running on multiple nodes simultaneously.

If possible you would be better to have package1 running on node1 and package2 running on node2 with node3 a standby for node1 and node4 a standby fore node2.

Hi,

Only possible if you can split your application to run on multiple nodes. Then you can package them and run through serviceguard. As long as your application supports that configuration, ServiceGuard shouldn't have any issues with it.

Oracle RAC, MQ/cluster etc., have the capability to load share.

Well...

if you already have a specific package that runs only on HPUX, then the next is not for you.

But,
if you are to set up an environment that needs such growth capacity that you might end up in needing the power of more than one node simultaniously, (like the config in the original question obviously is) then have a look again at VMS (officially called OpenVMS, nowadays also by HP).

ANY software that is NOT written specifically to PREVENT running multi-access (by explicitly specifying single-process access to data, which regrettably several database management software packages do), ALWAYS will run soncurrently on ANY number of cluster nodes. (supported up to 96 nodes, many more sometimes seen "in the wild").
.. and those nodes may be 800 KM ( = 500 miles) separated.

Well, probably the great majority of readers of this forum already have their systems running, and it would be difficult to justify such move, but for those that are in a planning phase, it could well be worthwhile to realise that there DO exist interesting solutions!


fwiw,

Cheers.

Have one on me.
