Combining Affinities Between Resource Groups

You can create more complex behaviors by combining multiple affinities. For example, the state of an application might be recorded by a related replica server. The node selection requirements for this example are as follows:

You can satisfy these requirements by configuring resource groups for the application and the replica server as follows:

Example 2–38 Combining Affinities Between Resource Groups

This example shows the commands for combining affinities between the following resource groups.

In this example, the resource groups declare affinities as follows:

This example assumes that both resource groups exist.

# scrgadm -c -g app-rg RG_affinities=+rep-rg
# scrgadm -c -g rep-rg RG_affinities=--app-rg
