Alternate Index requires the path in between Alternate index and base cluster for the faster access of the data from the dataset.

So path needs to be defined before building the index for alternate index.

IDCAMS DEFINE PATH command used to define an Alternate Index Path.

Path name will have a catalog entry but path does not contain any records.

The path name is specified in the JCL via the alternate index.

UPDATE/NOUPDATE

UPDATE/NOUPDATE parameters specifies records may be accessed by applications by the alternate index path alone, without opening the base cluster. In such cases any changes made to data will be reflected in the alternate index records if the UPDATE option is specified.

If NOUPDATE is specified then the alternate index records will not be automatically updated.
