O$er$iew

The prpose o! the 8alt 9anagement 8ramewor: is to provide error handling that is e&ternal

to S"# and does not impact the S"#;BPE< design or rntime. The !ramewor: is implemented

sing policies de!ined in =9hen hman intervention comes into pla', the Enterprise

9anager provides a G?I !or managing the !alted instance.

>hen the policies have been de!ined and bond to composites and;or components, the!ramewor: will intercept the !alt be!ore the standard !alt handler comes into pla'. 8ore&ample( i! a BPE< process has de!ined standard BPE< !alt handling and a !alt polic' hasbeen de!ined;bond to the BPE< process, when a !alt occrs the !ramewor: will intercept the!alt allowing an' o! the spported actions to be applied to the instance(
