Informix / MC Service Guard

[Schnabel]

Is there a posibility to configure a 2-Nodes-Cluster with Informix Dynamic-Server in a way that the clients are not disconnected in case of a failover.
Whats is the Enterprise Cluster Master Toolkit?

Thx

Hi,

I am not sure about Dynamic Informix and all, but when first node fails the second server has to reactivate the volumes and restart the applications, so there is no way you can keep the connection alive during switchover. I don't see any possibility of keeping the connections with any kind of tools.....We are also running Informix in cluster...If there is I will be happy to implement..:)

The ECM Toolkit is a set of suggested sample scripts and README's to enable you to get your application working correctly.
As for the Informix product, I have no knowledge of this in use in a ServiceGuard CLuster. You may want to ask Informix if they have implemented this.

NOT possible,

Service Guard has to shutdown database, deactivate VG's and remove IP-address in case of switch-over.

so Clients WILL lose connection to db server

Enterprise cluser master Toolkit is a collection of templates for different cluster aware applications
(databases, web servers etc.)

Hi Schnabel!
The only thing you can use similar to that, is OPS (Oracle Parallel Server). You can choose to use MCSG for OPS or only OPS.
But, for Informix, I don't know about any tool capable of what you ask.
