46 // Description: The classes represent the characterization of
47 // software resources (SW resource). A SW resource is an
48 // abstraction of the utilization of other entities in the
49 // environment (communications, memory, files, etc.) within
50 // the context of the software entity being managed. This version
51 // version of software resources concentrates on
52 // entities to transfer data over space and time from the
53 // internal view of running software. Processor/CPU-like resources
54 // are not considered for now.
55 // Software for which resources exist can be vary from operating
56 // system to application systems. An application system is
57 // an entity that supports a particular business
58 // function and that can be managed as an independent unit.
59 // The behavior a software resource is that items bundled
60 // in transfers are input to or output from the resource.
61 // What happens to the items inside the resource depends on
62 // type of resource (transferring data over time or space) and
63 // the implementation.
64 a.dunfey 1.1 // The following types of software resources are considered:
65 // Buffer, Queue, Protocol Endpoint, Remote Interface, Pool,
66 // Cache, File and Database.
67 // The software resources consist of statistics that
68 // describe their input, output and allocation (size).
69 // An associated settings class allows for setting
70 // the limits (I/O, allocation) of the software
71 // resource. The limits are designed as one of the levers
72 // to manipulate and control the operation of the software
73 // through managing software resources. The statistics
74 // provide the operational parameters of the limits, performance
75 // metrics and error information for performance and fault
76 // management functions as well as management tasks like
77 // monitoring, reporting or root cause analysis.
78 // Some of the software resources (file, protocol endpoint
79 // and database) are linked to existing classes since they
80 // cannot share the same base class due to existing,
81 // incompatible inheritance hierarchies and the fact that they
82 // are concurrently viewed and controlled outside the software
83 // by the OS. Thus, software resources are aspects of these
84 // existing objects.
85 a.dunfey 1.1 //
86 // They are maintained as a separate MOF file in the
87 // Application Model.
88 //
89 // The object classes below are listed in an order that
90 // avoids forward references. Required objects, defined
91 // by other working groups, are omitted.

104 "A Software Resource (SWR) is an abstraction of the utilization "
105 "of other entities in the environment (communications, memory, "
106 a.dunfey 1.1 "files, etc.) within the context of the software entity being "
107 "managed. SWR have a component-like implementation that is "
108 "independently manageable from the real entity outside the "
109 "software. These implementations are often used for storage and "
110 "transmission. Thus, a Software Resource (SWR) is: \n"
111 "a) any entity that is used by a system (e.g. an application "
112 "system) to transfer data over space and time (i.e., no data "
113 "processing in terms of creation/deletion or modification of "
114 "data). In contrast to normal (application) services (i.e., the "
115 "abstraction of data processing in terms of its "
116 "creation/deletion etc.), the SWR has limits (bounds) that are "
117 "not to be exceeded. This version does not consider resources "
118 "like CPU. \n"
119 "b) the system's view of such a transfer entity. Note that the "
120 "software resource is ultimately contained by or related to a "
121 "limited (physical or logical) resource of the encompassing "
122 "(operating) system such as memory, storage or a communication "
123 "links. \n"
124 "Anything transferred by an SWR is called an 'item'. Items may "
125 "be data, code, connections, packets, etc.. Items are atomic in "
126 "the model, thus there is no partial items. \n"
127 a.dunfey 1.1 "An instance only exists if a running system exists since it is "
128 "an internal component of the system implemented by its "
129 "software. Software resources are potentially external entities "
130 "like files viewed internally and (at least partially) "
131 "controlled by the software of the system. \n"
132 "SoftwareResource is contained by System via SystemComponent. "
133 "At least one system (e.g., one application system or a system "
134 "in general) contains 0 or more software resources. If more "
135 "than one system claims to contain the software resource, it is "
136 "a shared resource. \n"
137 "SoftwareResource is associated to SWRLimitSetting via "
138 "ElementSettingData. One software resource can have multiple "
139 "limit settings. Only one of the settings is the default and "
140 "one (potentially another one) is operational (current). "
141 "Settings can be shared by software resources. \n"
142 "SoftwareResource is associated to SWRStatistics via "
143 "ElementStatisticalData. In general, one software resource is "
144 "expected to have three statistics. The statistics type covers "
145 "each behavior characteristics at most once. I.e., the software "
146 "resource has at most one allocation statistcs, one input "
147 "statistics and one output statistics. Nevertheless, the "
148 a.dunfey 1.1 "implementation of the software resource may exhibit more "
149 "statistics SWRStatistics instances that cover more "
150 "context-specific behavior characteristics.")]
