SGeRAC and package active - standby

[Pablo Luis Romano]

We already have a cluster SGeRAC working perfectly, but we need to create a new package only active/standby.

This supported that in a cluster SGeRAC also has a package active / standby.
Which are problems or disadvantages?

SGeRAC contains everything that is in Serviceguard anyway, so absolutely you can create a standard "failover" type package and run it in the same cluster as RAC instances. There are no known problesm/disadvantages specific to doing this that I am aware of. Obviously good package design dictates that you keep packages as "loosely coupled" as possible (i.e. the minimum of interdependencies - seperate IPs, seperate filesystems, seperate disks and volume groups etc.)

What you describe is the advantage of using ServiceGuard with Oracle RAC is that you get all of the Oracle RAC functionality while you get all of the HA functionality of ServiceGuard.

Lan failover, Application packages for HA of other applications or failover oracle instances separate from RAC.

Go for it. This is a great way to do things.
