Coordinated Resource Recovery is a Virtual Machine/Enterprise Systems Architecture (VM/ESA) function for providing consistency of changes to multiple resources in environments that include distributed applications. It provides a uniform solution for applications to the problem of resource consistency. Systems management of Coordinated Resource Recovery in VM/ESA (CRR) is the set of system services and interfaces that support both automatic and manual procedures for managing CRR installation, performance, and recovery, as well as resource manager and application participation. Much of systems management is focused on application recovery from occasional failures of the procedures for coordinating consistent resource changes. This paper describes several key aspects of CRR systems management, including the CRR recovery log, facilities for minimizing manual intervention when failures occur, performance considerations, and application participation in recovery. |
