Method and system for providing service processor capability in a data processing by transmitting service processor requests between processing complexes

摘要

A method and system are provided for executing a service processor request within a data processing system having one or more processors within a central processing complex, each of the processors within the central processing complex including allocatable processor resources. Each of the processors within the central processing complex is provided with the capability of processing selected service processor requests by reserving a portion of the allocatable processor resources within each of the processors for such purpose. A service processor request within the central processing complex is initially processed utilizing at least one of the processors in response to receiving a service processor request, if sufficient processor resources are available to process the service processor request within the reserved portion of the allocatable resources. Alternatively, the service processor request is transmitted to an external processing complex, if insufficient processor resources are available to process the service processor request within the reserved portion of the allocatable resources.
