Using CA FAVER Functions › RESTORE › Cluster Definition

Cluster Definition

Once selected, clusters must be defined. By default, RESTORE does an auto-define: IDCAMS is called and the cluster or alternate index is deleted and automatically redefined using its original primary allocation and with its original file attributes. Auto-define provides these additional features:

• AMS override capability. The RESTORE parameter *AMS begins a list of AMS parameters that are to replace their counterparts during the define process. Only the parameters that need to be changed are coded. When used along with generic names, a small number of input parameters can change large groups of clusters.
• DEFINED parameter. Bypasses auto-define and uses an existing definition.
• REUSE parameter. Causes a reusable cluster to be opened empty and restored. Next, the alternate index or cluster is opened and all records are written back to disk.
