Service Guard- Cluster

[panchpan]

Hello.
I have one application running on HPUX. It has a database around 30 GB and also a batchscheduler tidal. I plan to have the application running on 4 node cluster. Please suggest IF there is any advantage to do so? Can database + application files + scheduler all could run on cluster or only scheduler.

Thank you for your advice.

Panchalp,

You may be aware of this but just wanted to let you know - if you are talking about running the application from all the 4 nodes of the cluster at same time (load balancing) then essentially you have to write the application in such a way that it is capable of working from all the nodes and still maintaining the consistency. For database you would have to use Oracle RAC and for scheduler - check with the scheduler software notes/vendor if it is capable of running on cluster.
Only after all these things would you be able to load balance the application over 4 nodes.
Also you would need a volume manager capable of sharing the storage across the nodes so that read/write is possible from all nodes to the application/scheduler filesystem area simultaneously from all the nodes.
If you are simply talking about high availability, thus if the server running the applcation fails, then the application is switched over to another server, then it may be possible without having the parallel running capabuility of the application, database and scheduler.

Ninad

You can run anything you want in a cluster.

You can have your apps run on a single node - or have then run on different nodes.

Can you load balance - that depends on the app.

Can you please provide me the link of SG Toolkit where I can find the information on setups of cluster based Progress/MfgPro application?

THANKS!!!
