Sharing VSAM files through RLS
By using the VSAM JCL parameter RLS
, you can specify record-level sharing with VSAM.
Specifying RLS
is the only way to request the RLS
mode when running COBOL programs.
Use RLS=CR
when consistent read protocols are required, and RLS=NRI
when no read integrity protocols are required. You
cannot specify RLS
if you allocate your VSAM data set with an environment
variable
