Database Software

Hi all,

we are facing an upgrade of Oracle Clusterware and ASM from 11.1.0.7 to 11.2.0.3.

We are in a mixed environmet, where we are using only 10g (10.2.0.4) databases with 11.1.0.7 clusterware and asm.

We configured the Cluster Interconnect over rdbms and asm with init.ora parameter cluster_interconnect.

Therefore the cluster interconnect ist not shown over oifcfg:

# oifcfg getif
bge50000 192.168.5.0 global public

When upgrading to 11.2.0.3 and while issuing the pre Upgrade Check it turns out, that the cluster_interconnect needs to be set.

I have already read the doc 283684.1 about Modification of the cluster Interconnect.

But I'm not sure if I need to restart the clusterware stack after this modification.

The modification would not be a change in my opinion.
It would only put the already configured interface for Cluster Interconnect into the ocr by issuing the following:

# oifcfg setif -global nxge1/192.168.200.0:cluster_interconnect

So my question is, if the modification would recommend a restart of both Clusterware Stacks on both nodes?

If so, could it be made in a rolling manner, for example while patching crs on 11.1.0.7.7,
meens issuing command before patching node 1 (crs is down on node1), then patching node 2 after crs is up again on node 1?

Thanks in advance

Matthias
