5.3 DMI Functionality

DMI functionality for the SEA includes the following:

• Dynamic installation and removal of component instrumentations and management application

• Responsibility for all runtime access to the MIF data

• Assurance that at least one group (the component ID group) is in each MIF file

• Responsibility for launching the component instrumentation, if necessary

• Slicing commands. When a management application requests more than one attribute value from a component in a single command, the SP sends commands to the component instrumentation for each attribute

• Assurance that commands serialize to a component instrumentation and ensure that commands are allowed to run to completion. Multiple requests for a particular component instrumentation must be queued

• Provide event/indication subscription and filtering

• Forward indications based on subscription and filters to each registered management application and timestamp incoming indications before forwarding them

• Send indications to all registered management applications that subscribe to receive indications when components are installed or removed from the MIF database

• Appear to management applications as a component with ID 1 (one). As a component, it must support the standard ComponentID group. Additionally, the DMI SP must support the subscription and filter standard group. Also, similar to a component, it may define additional groups beyond the ComponentID group
