Researching VSAM RLS as a way to eliminate downtime

If you’re among the estimated 90 percent of organizations with CICS applications that rely on VSAM files, you know that updating those files can involve availability and data integrity issues. In a traditional environment, only one CICS region or one batch process at a time can have control over the VSAM files to maintain data integrity. VSAM RLS changes that, but myths about everything it can do still exist.

In this briefing, you can find out when VSAM RLS helps with providing greater availability while preserving data integrity. You can also see what RLS’s limitations are, especially in relation to CICS and batch. Understand the benefits and limitations of this often discussed solution for CICS, and see the crucial points to consider in relation to your situation.
