<p>A method and system fox managing a large number of servers and their server components distributed throughout a heterogeneous computing environment is provided. In one embodiment, an authenticated user, such as an IT system administrator, can securely and simultaneously control and configure multiple servers, supporting different operating systems, through a 'virtual server.' A virtual server is an abstract model representing a collection of actual target servers. To represent multiple physical servers as one virtual server, abstract system calls that extend execution of operating-system-specific system calls to multiple servers, regardless of their supported operating systems, are used. A virtual server is implemented by a virtual server client and a collection of virtual server agents associated with a collection of actual servers. A method and system for executing and undoing distributed server change operations for a collection of server objects across multiple target servers in a transaction-safe manner is provided.</p> |
