Hi,

What is the actual definition of clusters in IMS?
As far as i have seen in JCLs which run IMS programs we provide some VSAM datasets that point to the IMS db. Are these called Clusters?

Please clarify.

Thanks.

When an IMS database is defined using VSAM with IDCAMS you define a cluster. So the answer is yep unless you mean something else. Follow the first link in the sticky and learn a lot icon_idea.gif
