Answer / codebulls
At times a vendor might offer a file to be consumed by a mainframe application. Rather than the primary key, the file would contain another field in the VSAM which is unique but not the primary key of VSAM. If such fields are made to be Alternate Index, unnecessary reads and performance overhead can be avoided.

Answer / sanjana
we use aix to reduce the fields in base table.in further
divided tables will have their own primary key for each
table.in this way we can search the records in the cluster
very easily.

Hi...........
we use AIX to extend the limit of Keys.
Suppose i have following records with key(5,0)
00001 Ravindra Uttaranchal
00002 Reena Uttaranchal
And We got new records from Client as following
00001 Manmohan New Delhi
00002 Gaurav New Delhi
So there may be confliction
To resolve this we create AIX on KSDS/ESDS.
Thanks & Regards.
