in my ksds vsam file ....

vsam-rec
05 KEY-FLD
10 REGN X(9).
10 NRIC X(8).

The primary key is KEY-FLD and alternate key is NRIC.

i've defined the vsam cluster with keys(17,0)

and in my cobol program i'm using the alternate key to
access single record in this vsam file.
is there a need to build an alternate index for this vsam file.

Sure, you have to BLDINDEX and also to DEFINE PATH otherwise you can't access VSAM file using AIX .

I think the build index would be required only if you a creating alternate index to an existing VSAM file (ie) which has some records.
Correct me if im wrong
