<h2><a name="Functionality of This Release">Functionality of This Release</a></h2>

The overall level of functionality in the Pegasus environment effective with

this release is as follows:

<h3>CIM Server Functionality</h3>

The following paragraphs list the functions in this release.  All

functions are considered community tested and operational unless specifically

noted below. Features that are marked alpha or beta are not generally of the

quality or completeness for production usage.  Interfaces that are

part of the Pegasus public interface definitions but that the Pegasus team feels

may change are marked experimental. In many cases these features  and

interfaces are conditionally compiled with special environment variables. PEP

174 provides more detailed information on how to enable functionality that is

conditionally compiled in this release.

<h4>CIM Operations over HTTP support</h4>

<ol>

<li>Class Operations (getClass, <span

class=SpellE>deleteClass, modifyClass, <span

class=SpellE>enumerateClass, enumerateClassNames)</li>

<li>Qualifier Operations (getQualifier, setQualifier, deleteQualifier) </li>

<li>Instance Operations (getInstance, <span

class=SpellE>deleteInstance, modifyInstance,

enumerateInstance, enumerateInstanceNames,

getProperty, setProperty)</li>

<li>Association Operations (references, referencenames,

associators, associatornames)</li>

<li>Methods Operations (invokeMethod)</li>

<li>Query operation - Support for ExecQuery was added in 2.4 with

WQL as query language and is defined in PEP 119. This feature is considered at

alpha quality because it has only been contributor tested and there is no test

in the test suite to confirm the functionality.</li>

</ol>

</blockquote>

</div>

This is a place-holder for the 2.5 Release Notes which be added just before

the release.

<h4>Indications</h4>

Earlier versions can be downloaded from CVS, or from among the Release PEPS

Process indications are operational in the Server.  This includes support

here</a>.

for subscriptions, filters, and indication handlers, the provider API for

<span

indications and the CIMXML indication handler.

<h4>Indication Listener</h4>

The generic components for a CIM

Listener and a listener API are operational.  This includes the functions

for HTTP, XML indication input and response, and consumers of indications. This

code can be used to define a separate listener package and is used as an

indication listener in the Pegasus server.

</blockquote>

<h4>Query Language</h4>

The query language today is based on WQL and is implemented and used for

filters and in 2.4 for execQuery.  The execQuery support  for WQL has

been implemented in Pegasus 2.4 but is considered alpha quality.

<h4>Class Repository</h4>

Pegasus uses an XML based file/directory class repository. All class and qualifier operations

access this repository. The repository was modified to improve efficiency in 2.4

by adding a binary repository option to reduce repository size. The binary

repository functions are considered alpha level because they have only been

contributor tested and there is no test function in the automated Pegasus test

suite.

<h4>Instance Repository</h4>

Pegasus uses an XML based file/directory Instance repository.  The

instance  repository may be conditionally used as the default repository

with a Pegasus configuration flag ( As defined in PEP 174, it is normally set 

to NOT use the instance repository as default).

<h4>Server Security</h4>

<li class=MsoNormal style='color:black;mso-list:l14 level1 lfo6;tab-stops:

list .5in'>Basic Authentication (Note that Digest based security is not

implemented) <o:p></o:p></li>

<li class=MsoNormal style='color:black;mso-list:l14 level1 lfo6;tab-stops:

list .5in'>SSL support - SSL is implemented in Pegasus using the <span

class=SpellE>OpenSSL libraries. Pegasus does not provide the <span

supported by OpenSSL.  Minimum level known

to work is  0.9.6c .   This release of Pegasus was tested

with 0.9.6k.  See <a

</ol>

<h4>SLP Discovery</h4>

SLP support is included but is conditionally compiled with the default.  This code can be enabled by setting the compile

environment variable PEGASUS_ENABLE_SLP.   Once compiled, SLP support

is enabled with the slp configuration parameter (slp=true). SLP support includes

an SLP service agent in the Pegasus CIM severas and generates SLP advertisements compatible with the DMTF

slp template specification. The SLP support also includes  extensions to the CIM

Client libraries to execute SLP User Agent requests and analyze the results

(note that these interfaces are not yet part of the Pegasus public SDK).

<h4>Provider Managers</h4>

Pegasus is designed to support multiple Provider Managers to allow multiple

provider interfaces to the CIMOM.  The default provider manager is the C++

Interface.  This section defines the additional provider managers available

with Pegasus 2.4.

<h5>CMPI C interface Provider Manager<o:p></o:p></h5>

Pegasus 2.4 includes a provider manager for the CMPI C interfaces.

This C interface is the result of a project by the IBM SBLIM team (<span

class=GramE>see� <a

href="http://www-124.ibm.com/sblim/)">http://www-124.ibm.com/sblim/)</a> and

also the working draft of the Open Group specification for these interfaces

which is in review now within the WBEMSource

Initiative (<a href="http://www.wbemsource.org/">http://www.wbemsource.org</a>).

This provides a standardized C level interface for creating providers that can

be registered with the Pegasus CIM Server in the same manner as the current C++

providers.

Today, the CMPI provider manager and interfaces are considered experimental

and are subject to change in future versions of Pegasus  until the CMPI

specification is released. Information on writing providers with the CMPI

interface is available in the draft version of the specification today (see

above) and in the following documents (<a href="http://www-124.ibm.com/sblim/doc/CMPIandC++.pdf">http://www-124.ibm.com/sblim/doc/ProviderArchitecture.pdf

</a>and <a href="http://www-124.ibm.com/sblim/doc/CMPIandC++.pdf">

http://www-124.ibm.com/sblim/doc/CMPIandC++.pdf</a>) and readme.cmpi in the

Pegasus source root directory.

<h5>JMPI Java Interface Provider Manager</h5>

Pegasus includes an experimental provider manager for Java provider

interfaces based on the SNIA provider interface definitions.  This provider

manager is  considered alpha quality and is not compiled in the default build.  

See readme.jmpi in the Pegasus source root directory for more information.

</blockquote>

<h3>Providers</h3>

There are a number of providers available in the Pegasus release.

This includes providers in the following categories:

<h4>Pegasus Internal Providers</h4>

Pegasus provides a set of "internal" providers that have direct access to the

CIMOM for information and provide information and services to support the CIMOM

and its administration.    The providers in this category are mostly defined in the directory src/pegasus/controlproviders

and include support for the following classes:

<ul>

<li>DMTF Interop classes including __Namespace,  <span

class=SpellE>CIM_Namespace, CIM_ObjectManager,

CIM_CommunicationMechanism, and CIMOMStatistics.</li>

</ul>

<h4>Generic Providers</h4>

Generic OperatingSystem provider. See the

directory src/Providers/generic.

<h4>Test/Sample Providers</h4>

See the directories src/Providers/TestProviders

and src/Providers/Sample for more information about test and

sample providers.

<h4>Managed System Providers</h4>

ComputerSystem, DNSAdmin,

DNSService, Operating System, Process, Processor. For

more information on these providers see the documentation for each provider in

the directory src/Providers/ManagedSystem

<h4>SLP Provider</h4>

This provider acts as the definer of  SLP

information for SLP registration and also controls the Pegasus SLP Service

Agent. It is treated as a normal provider rather than a control provider because

it does not use internal functions of the CIMOM to generate any of its

information today. (conditionally compiled today)

</blockquote>

<h3>CIM_Schema</h3>

The default CIM_Schema loaded with this release is

the DMTF CIM 2.8, Final release.  In addition, Pegasus includes a number of

local classes defined for Pegasus.  These are defined in the pegasus/Schemas

directory.   CIM 2.9 preliminary

schema is also available in the CVS but is not the default schema for compile. 

There are also a number of older schema available in the CVS.

The mechanism to install other schemas than the default is

defined in the mak/config.mak

NOTE: The CIM 2.5 schema is maintained in the

CVS repository because it remains the basis for parts of the Pegasus test

environment.

<h3>Pegasus MOF Compilers</h3>

Pegasus implements a MOF compiler that can operate either at the client

interface to the Pegasus CIM Server (cimmof) or directly interfacing with a CIM

repository (cimmofl).

The direct interface compiler is used primarily to provide an initial

class/instance repository. WARNING:

the use of cimmofl

to manipulate instances in the repository bypasses any provider that is

registered to serve these  instances and simply installs the instances in the

instance repository; this may result in 1) bad data in the repository if there

are registered providers, 2) corruption of the repository if the CIM Server is

running or, 3) MOF data that is loaded but not available until the server is

stopped and restarted in some cases.  Use of cimmofl in

general is discouraged and particularly  to manipulate

instances served by a registered providers (ex.

Provider registration). Use of <span

class=SpellE>cimmof rather that cimmofl is encouraged

wherever possible.

<h3>Pegasus Interface APIs</h3>

Details of the Pegasus public interfaces for this release are listed in PEP

189

available from the web site(<a

href="../Administrator/My%20Documents/processes/www.openpegasus.org">www.openpegasus.org</a>).

That document is the authorative source for the list

of publicly supported Pegasus APIs.   The Client and Provider API were

originally frozen at the Pegasus version 2.1 release. The interfaces in the

release of Pegasus 2.1 are forward compatible to this release. Well-behaved

clients and providers compiled to the Pegasus 2.1 or 2.2 interfaces should be

compatible with this release without compilation.  There have been

extensions and new interfaces added for this release and these are marked as

experimental.   The Pegasus public

interfaces includes the following major functions

<li class=MsoNormal style='color:black;mso-list:l5 level1 lfo24;tab-stops:

list .5in'>Client APIs<o:p></o:p></li>

<li class=MsoNormal style='color:black;mso-list:l5 level1 lfo24;tab-stops:

list .5in'>Provider APIs<o:p></o:p></li>

<li class=MsoNormal style='color:black;mso-list:l5 level1 lfo24;tab-stops:

list .5in'>CIM Object and System function APIs</li>

</ol>

In addition, there are other client interfaces which are not today in the

public SDK including:

<li class=MsoNormal style='color:black;mso-list:l5 level1 lfo24;tab-stops:

list .5in'>CIM Listener APIs</li>

<li class=MsoNormal style='color:black;mso-list:l5 level1 lfo24;tab-stops:

list .5in'>SLP Client (User Agent) APIs which are

extensions to the Client APIs</li>

</ol>

<o:p> </o:p>

The APIs are documented in

their respective header files and  in HTML documentation based on the information

in the header files extracted with the doc++ tool will be available on the

OpenPegasus web site. <o:p></o:p>

<h3>WMI Mapper</h3>

The WBEM to WMI Mapper provides a way to access

WMI data from Windows platform systems. It converts incoming XML/CIM requests

to Microsoft WMI requests, executes the requests, converts the results to

XML/CIM and returns the results to the client. WMI Mapper

receives an HTTP message containing the XML/CIM request. It decodes the XML

message and extracts from the HTTP message header the user credentials provided

on the connection (username and password). The WMI Mapper

authenticates these credentials, verifying if the provided credentials have

access to the desired WMI data. This is done because the WMI <span

class=SpellE>Mapper runs as a service, logged on using an account with

administrative rights (which has all access to WMI data). Because of this, the

WMI Mapper impersonates the user credentials provided

on the HTTP message to ensure that the calling user has rights to browse WMI

data. Hence, ALL requests made to the WMI Mapper MUST

contain user credentials.

<h2><a name="Supported Platforms">Supported Platforms</a></h2>

Each Pegasus release lists as supported platforms those

hardware/software platforms that have recognized ports for the Pegasus code

base including a maintainer for the platform that will be willing to regularly

assure that the port is maintained as the Pegasus code base is changed. 

Pegasus may be operable on other platforms (ex. Windows 98) but without a group

to provide the role of test and maintenance, the Pegasus project cannot assure

operation. The supported platforms for this Pegasus release are:

<h2><a name="Conformance with DMTF Specifications">Conformance with DMTF Specifications</a></h2>

It is a major goal

of the OpenPegasus project to both drive and utilize the DMTF CIM/WBEM

specifications.  However, today there are a number of known differences. 

As of this release, some of the differences include the following:

<ol>

<li>Provider Registration - Pegasus supports registration through a set of

Pegasus Provider registration classes rather than support the DMTF defined Provider

Qualifier. Pegasus will not support this qualifier in the future. See the readme for more information on provider registration.</li>

<li> Indications -Today Pegasus supports process indications but does not

include any specific support for lifecycle indications.</li>

<li>

Instance qualifiers and class

qualifiers on some Operations -

The DMTF specifications are unclear regarding the inclusion of qualifiers on

CIM instances.  Some CIM Client implementations expect instances returned

from the CIM Server to include the qualifiers defined in the class definition

(such as KEY qualifiers on properties).   Pegasus today expects the provider to complete the qualifiers on instances in

accordance with the specification and generally the interpretation is that

Pegasus applies class level qualifiers when the includeInstance parameter is

supplied on instance operations.  However, Pegasus today is inconsistent in

the return of qualifiers so that the user should NOT depend on Pegasus

accurately honoring the includeQualifier parameter for instance operations. 

In the future it is expected that Pegasus will deprecate the use of qualifiers

on instance operations completely.

</li>

<li>

CIM MOF compiler function for instance aliasing - The

Pegasus MOF compiler does not today support this function.  This function is

planned for a future version.

</li>

<li>

MultiRequest Oprations - Pegasus does not support the DMTF defined MultiRequest

Operation option.

</li>

<li>

LocalOnly option on some instance Operations -

With the 1.1 version of Specification for CIM Operations over HTTP, the

definition of the LocalOnly parameter for the GetInstance and EnumerateInstances

operations was modified. This change was incorrect, resulted in reduced

functionality and introduced a number of backward compatibility issues. As a

result of issues introduced by this change, we strongly recommend that CIM

Clients set LocalOnly = false and do not rely on the use of this parameter to

filter the set of set of properties returned.

</li>

<li>

MOFCompiler namespace pragma - The Pegasus compiler does not support the namespace pragma.

</li>

</ol>

<h2><a name="Changes in This Release">Changes in This Release</a></h2>

The development and release of each version of Pegasus is defined and

controlled through Pegasus PEP documents.  PEP 97 is the controlling document

this release and lists the original set of changes proposed and the status of

each of those changes. Note that not all of the originally defined

functionality was completed for this release.

In general, the areas of development for this release were:

<li class=MsoNormal style='color:black;mso-list:l21 level1 lfo27;tab-stops:

list .5in'>

Expansion of platform globalization.</li>

<li class=MsoNormal style='color:black;mso-list:l21 level1 lfo27;tab-stops:

list .5in'>

Expansion of SLP support (still

experimental and by default not compiled in the 2.4 release).</li>

<li class=MsoNormal style='color:black;mso-list:l21 level1 lfo27;tab-stops:

list .5in'>

Inclusion of the Pluggable Provider   manager

(Providermanager2)as the default provider manager. Note that the original

provider manager will NOT be supported in the future.</li>

<li class=MsoNormal style='color:black;mso-list:l21 level1 lfo27;tab-stops:

list .5in'>

Inclusion of Pluggable

CMPI provider manager and the JMPI provider.  </li>

<li class=MsoNormal style='color:black;mso-list:l21 level1 lfo27;tab-stops:

list .5in'>

Inclusion of the out-of-process

provider mechanism and the remote provider mechanism for CMPI. (Experimental)</li>

<li class=MsoNormal style='color:black;mso-list:l21 level1 lfo27;tab-stops:

list .5in'>

Addition of the binary repository

option. (Experimental)</li>

<li class=MsoNormal style='color:black;mso-list:l21 level1 lfo27;tab-stops:

list .5in'>

Addition of the shared namespace

concept so that class and qualifier definitions can be shared between multiple

namespaces. (Experimental)</li>

<li class=MsoNormal style='color:black;mso-list:l21 level1 lfo27;tab-stops:

list .5in'>

Refactoring of the HTTP monitor.</li>

<li class=MsoNormal style='color:black;mso-list:l21 level1 lfo27;tab-stops:

list .5in'>

Addition of HTTP chunking.

Note that the internal segmenentation of operation responses allowing better control of memory within

the cimom is planned for the future.</li>

</ol>

Note that there were a number of objectives that were not completely achieved

including: <o:p></o:p>

<li class=MsoNormal style='color:black;mso-list:l10 level1 lfo30;tab-stops:

list .5in'>Complete move to segmented operation responses and positive control of memory

for operations.   The chunking code has been incorporated and the

Pegasus client and the Server HTTP components handle chunking.  The

components necessary to segment operation responses from the providers was not

completed and will be included in a future version.</li>

</ol>

The complete set of PEPs defined for this release is

defined in PEP 97.

Pegasus Release Control and Version Definition Documentation</a></h2>

The Pegasus project is controlled largely through a set of documents (PEPs)

that serve as the definition and review mechanism for new and modified Pegasus

functionality and for the definition and documentation of releases.

Specifically the following PEPs define the characteristics of this Pegasus

release.

<ol>

<li>PEP 189 - OpenPegaus 2.4 External Interfaces</li>

<li>PEP 188 - OpenPegaus 2.4 Packaging Definition for Selected Platforms</li>

<li>PEP 185 - Pegasus 2.4 Release Notes (This document)</li>

<li>PEP 181 - OpenPegasus 2.4 SDK Packaging Definition</li>

<li>PEP 175 - Pegasus readme.txt for 2.4 (also in the Pegasus source tree root

directory).</li>

<li>PEP 97 - OpenPegasus Release Definition - This PEP is used throughout the

development of this version as the control point for functionality that will

go into the release and points to all of the PEPs that represent the Pegasus

2.4 functionality changes.</li>

</ol>

<h2><a name="General Documentation">General Documentation</a></h2>

The following documentation is available for the this Pegasus release:

<li class=MsoNormal style='color:black;mso-list:l2 level1 lfo33;tab-stops:

list .5in'>Utilities - A combination of help generally available with the

-h option for each command and HTML documentation for most of the tools.<o:p></o:p></li>

<li class=MsoNormal style='color:black;mso-list:l2 level1 lfo33;tab-stops:

list .5in'>API and  usage documentation - See the header files and the

HTML  API documentation that is on the web site. The best API usage documentation is

the existing utilities and test programs and the examples in the API

documentation.  In particular the

Common/tests unit tests contain extensive examples of the use of the

Common APIs.</li>

<li class=MsoNormal style='color:black;mso-list:l2 level1 lfo33;tab-stops:
