RLS is a VSAM function , provide by DFHSMS , that enables
data to be shared with full updates capability, between many
applications running in many CICS programs. With RLS CICS
share VSAM data sets can reside in multiple MVS images
within a parallel sysplex, RLS also provide the benefits
when data sets being shared between CICS regions and batch
jobs. also provide different level of READ integrity and
update with Browse.
So if multiple application use same VSAM file then better
option to use VSAM RLS.
Second we can achieve by using SUSPEND option , it allow the
application programs to control the action if the records to
be accessed in unavailable .
