• Detect and report that an abnormal situation is no

longer apparent or relevant by clearing the related

exception condition and reporting it if enabled.

• Provide for enabling and disabling reporting on

each exception condition.

• Maintain the data of exception condition attributes

indicated in Table 2.

• Reject requests for capabilities not supported (such

as recovery actions).

10.4.2 Interactive Exception Handling — The

fundamental requirements of the exception agent for

interactive exception handling extend the exception

reporting to allow the decision authority to request

recovery actions to be performed to resolve abnormal

situations. These are listed below.

• Support all exception reporting fundamental

requirements specified above.

• Supply a list of valid recovery actions for an

exception condition when posting.

• Execute a requested recovery action for an

exception condition if the requested recovery

action is currently valid. The exception agent may

support only a single recovery action to be in

progress at a time and reject all other recovery

action requests for other exception conditions

while it is busy.

• Report the completion of the recovery action.

• Support Abort of the recovery action at all times,

immediately ceasing recovery activity and

terminating the recovery action.

• Reject requests with incomplete or invalid

parameters.

• Reject requests for capabilities not supported.

Optional capabilities defined or enabled in this standard

include the following:

• Support for multiple concurrent recovery actions.

The standard allows only one recovery action in

progress for each exception condition.

• Adjust the exception condition message and the

valid recovery action list as appropriate during the

error recovery, and post the changes if reporting is

enabled.

The services are defined with mechanisms to reject

unsupported services and options should they be

requested. This improves robustness and enables

sophisticated service-users to adjust its requests to the

capabilities of the particular exception agent.

7 Implementation Details

7.1 Several capabilities of the Exception Management Services (EMS) are accessed through the Object Services

Standard. The Exception Objects are persistent. An Object Services compliant implementation of EMS will allow

access to all the attributes specified in the SEMI E5 Object definition table for an Exception Object.

All implementations shall use Object Service’s GetAttr and SetAttr to access:
