Management Policy
Policy influences behaviour of objects
Need to specify and modify policies without coding into automated agents
But can be dynamically modified
Notes:
Change policy to change behaviour
Traditional systems - policy is coded into programs of controllers or agents
To change policy have to edit, recompile, stop agent and reload new program
Request to backup staff PCs is not a policy but a 1 off command
A persistent policy would say “archiver must back up staff PCs every night at 1 am”.
