I have created one AIX for a base cluster with UPGRADE option,now the rule is if i change something in the base cluster it will be updated in the AIX cluster also, now as wi know that the AIX is also a cluster itself so if we change something in it will it be upgrade in the bsae cluster as well?

If you update the Base Cluster, it's reflected in your AIX.

The base Cluster is usually defined first. Then an alternate index is created and a build index is run against the original dataset building a list of all the alternate index keys. The data is not held in the alternate index, just the reference to the original dataset.

If you insert a RECORD into the base cluster USING the alternate index then that is ok. If you try to insert a index directly into the alternate index then the base cluster knows nothing about it.
