Performing partial subnet initialization in a middleware machine environment

A method for performing subnet initialization in a middleware machine environment, comprising:

• interconnecting a plurality of management nodes running on one or more microprocessors in the middleware machine environment, wherein the plurality of management nodes allows a plurality of subnet managers that are associated with the plurality of management nodes to communicate with each other using an in-band communication protocol;
• negotiating among the plurality of subnet managers and electing a subnet manager as a master subnet manager, wherein the master subnet manager operates to configure and manage the middleware machine environment;
• replicating one or more subnet initialization policies, via the master subnet manager, to other subnet managers in the middleware machine environment using the in-band communication protocol;
• and
• setting up a plurality of client nodes in the middleware machine environment based on the one or more subnet initialization policies.

A machine readable medium having instructions stored thereon that when executed cause a system to perform the steps of:

• interconnecting a plurality of management nodes running on one or more microprocessors in the middleware machine environment, wherein the plurality of management nodes allows a plurality of subnet managers that are associated with the plurality of management nodes to communicate with each other using an in-band communication protocol;
• negotiating among the plurality of subnet managers and electing a subnet manager as a master subnet manager, wherein the master subnet manager operates to configure and manage the middleware machine environment;
• replicating one or more subnet initialization policies, via the master subnet manager, to other subnet managers in the middleware machine environment using the in-band communication protocol;
• and
