Products

• NetMaster Network Management for TCP/IP

Issue/Introduction

 When VSAM RLS (Record Level Sharing) is recommended for UAMS (Userid Access Maintenance System) dataset?

 

Environment

Release : 12.2

Component : CA NetMaster Network Management for TCP/IP

Resolution

Any times you want to SHARE the UAMS file with another region, you should use RLS.

 

From the Install or Upgrade manual - 

Multiple users on multiple systems can update a UAMS VSAM data set simultaneously. The standard VSAM share options do not ensure data set integrity with simultaneous updates from multiple systems. Using RLS, the UAMS VSAM data set can be shared without the possibility of corruption, which reduces the possibility of region outage.
