Multi-phase commit processing for creation and deletion of managed objects

In a computing system having a manager application that creates and deletes managed object instances (MOIs) within a plurality of MOIs contained in an agent application running on a management platform, said MOIs organized in an MOI hierarchy mapped as an MOI tree, a computer implemented method for multi-phase commit processing of a create MOI request sent by the manager to the agent comprising the computer implemented steps of:

• receiving the create MOI request within the platform;
• validating the create request within the platform by checking the MOI to be created against the MOI hierarchy;
• registering the requested MOI within the platform as a pending instance node in the MOI tree;
• sending a create request for the requested MOI from the platform to the agent,
• testing at the agent whether the create request is acceptable;
• deleting the pending instance node from the MOI tree if the agent indicates the create request is unacceptable;
• finish connecting the pending instance node to the MOI tree, if the agent indicates the create request is acceptable, whereby the MOI becomes operative in the MOI hierarchy.

In a computing system having a manager application that creates and deletes managed object instances (MOIs) within a plurality of MOIs contained in an agent application running on a management platform, said MOIs organized in an MOI hierarchy mapped as an MOI tree, a computer implemented method for multi-phase commit processing of a delete MOI request sent by the manager to the agent comprising the computer implemented steps of:

• receiving at the platform a delete MOI request from the manager;
• validating the delete request within the platform;
• registering each MOI within the scope of the delete request in a pending delete list;
• sending a delete request to each MOI in the pending delete list;
• determining whether each MOI receiving a delete request is deletable;
• generating a final delete list containing only those MOIs on the pending delete list that said determining step determines to be deletable;
• deleting the MOIs on the final delete list.

In an interconnected computing system having a manager application (manager) in a first computing system and an agent application (agent) in a second computing system and wherein the manager creates and deletes managed object instances (MOIs) in the agent via a common management information protocol (CMIP) platform, apparatus for multi-phase commit processing of a create or delete MOI request sent by the manager to the agent, said apparatus comprising:

• receiving means in the CMIP platform for receiving and validating a create or delete MOI request from the manager to thereby generate validated requests;
• means responsive to the receiving means for adding validated requests to a pending request list in the CMIP platform;
• means for sending a validated request from the CMIP platform to the agent;
• means at the agent for testing whether the validated request is acceptable;
• means responsive to said testing means for marking pending requests on the pending request list in the CMIP platform as final requests if the validated request is acceptable;
• means responsive to the final request list in the CMIP platform for executing each final request at the agent.
