Resource Access Security (RAS)

IMS r9.1 introduced RAS as a replacement for AGNs and AGN security. In IMS r10.1, AGNs and AGN security is removed.

With RAS, IMS performs a direct security validation of the terminals, PSBs, and transactions that a dependent region can access. For example, before a transaction is scheduled to execute in a message processing regions, IMS performs a security validation to see if the logonid of the message processing region is allowed to execute the transaction. If not, the transaction is not scheduled in that message processing region.
