Pegasus is regularly tested against a variety of platforms by the
development group. The results of the nightly tests can be found
here: Nightly
test status . The Release notes provides additional details
regarding the platforms.
PEP 249 is the Release Notes PEP for 2.5.x.
To see simple help for a command, invoke it with the "--help" option.
Here is a list of useful commands:
Some of the basic commands:Much of Pegasus is documented in the PEGASUS PEPs which are the basis for approval of Pegasus functionality, changes, plans, etc. These documents are openly available on the PEGASUS web site. The current documentation is maintained both as a manual created under the tool DOC++ in the runtime subdirectory manual/html (see doc/devManual to create), as an api document also creatable from the source tree (see doc/apidoc) and as other miscellaneous documentation in the doc directory. Also there is a set of release notes. Normally the release notes for the current release are available in the root source directory of CVS.
Note that the Pegasus WEB site at The Open Group will be the source of most documentation in the future and today is the source of most discussion and design documentation.
Contributors are welcome to participate in the OpenPegasus development effort. Join the mailing list by visiting http://www.openpegasus.org and clicking on Mailing Lists. Joining the pegasus-l mailing list will provide a login/password for the website.
NOTE: Linux RPMs are only available for a limited set of releases.
The distribution is available via CVS and snapshot images in tar and zip file formats on the web site. The source code from CVS can be found at the Open Group CVS server - cvs.opengroup.org. The source can be checked out anonymously using the instructions at http://www.openpegasus.org/page.tpl?ggid=667
CVS write accounts are managed by Martin Kirk of The Open Group (m.kirk@opengroup.org)
RPM installation instructions can be found here: http://www.openpegasus.org/pr
We have worked to minimize the dependence of Pegasus on other software packages and tools. Currently Pegasus has the following dependencies:
1. GNUMAKE - To simplify the building of Pegasus across multiple platforms we have standardized on a set of build tools including: GNUMAKE. We are using GNUMAKE 3.79.1 successfully both in Windows and Linux environments.
GNUMAKE is available from :
2. FLEX and BISON - These tools were used to develop the MOF compiler and WQL parser. These tools are required only for development of the parsers, not for building Pegasus.
3. DOC++ - The Pegasus documentation is taken from a combination of text files and the Pegasus header files themselves. This documentation is formatted with DOC++ and GAWK. These tools are required to build the interface documentation set.
4. ICU Internationalization libraries - These libraries are used as the basis for message catalogs for message internationalization. See the ICU website (http://oss.software.ibm.com/icu/) for more information on these libraries
5. OpenSSL - If it
is intended to use SSL on the
communication protocol, the OpenSSL libraries are required.
NOTE: A set of the required tools for windows platforms is available on the openpegasus web site. www.openpegasus.org
Before installing or running OpenPegasus, environment variables may
have to be defined or updated.
PEP 237 contains the list of environment variables and setup necessary to use OpenPegasus.
At a minimum, the following need to be set:PEGASUS_ROOT=<location of your pegasus source tree>
PEGASUS_HOME=<location for the built executables, repository, etc>
PEGASUS_PLATFORM=<your platform>
For a list of valid
platforms, enter "make listplatforms" from the root of the Pegasus
source tree.
To build OpenPegasus on Linux, ensure that you you have the environment
variables set (PEGASUS_HOME, PEGASUS_ROOT, PEGASUS_PLATFORM. For
32 bit linux, the definition of PEGASUS_PLATFORM is normally
LINUX_IX86_GNU).
To build with SSL you need the OpenSSL libraries and header files. They are NOT distributed with OpenPegasus. Make sure you have them in a standard directory so OpenPegasus can find them. If that's not the case, set the environment variable OPENSSL_HOME= to point where your OpenSSL installation is.
Also have the PEGASUS_HAS_SSL=true variable set. Then just run 'make' in Pegasus directory and you will have OpenPegasus with SSL enabled. See "Creating SSL certificates" below for more information on how to use SSL.
Refer to the OpenPegasus SSL Guidelines guide found in the doc directory for details on using OpenPegasus with SSL.Use of Windows 2000 SP3 or later is recommended. OpenPegasus is regularly tested on both Windows 2000 and Windows XP using the Microsoft compilers.
Today we build OpenPegasus on Windows using a set of make files contained in the source distribution, the Microsoft compilers (DevStudio 5.x is not supported, Visual Studio 6.0, SP5 is supported) and the GNUMAKE make utility. Note that you MUST have the OpenPegasus mu.exe utility compiled and available before trying to compile OpenPegasus on the normal windows platform. The following is the basic setup steps for the environment.
Setup the environment variables and path for the Micrososft Visual C compiler. Typically this can be done by running the VCVARS32.BAT file supplied with Microsoft Visual C++. (contained in the same directory as cl.exe).
For Windows, try the following for an example environment:
REM call the standard Microsoft .bat for VC 6 setup.
call 'C:/Program Files\Microsoft Visual Studio\VC98\Bin\Vcvars32.bat'
REM Set debug to something if you want compile in debug mode
set PEGASUS_DEBUG=true
REM set PEGASUS_ROOT to top of source tree
set PEGASUS_ROOT=C:/cimom/pegasus (Note: The '/' characters are intentional and required by the OpenPegasus build system)
REM set PEGASUS_HOME to where you want repository and executables
set PEGASUS_HOME=%PEGASUS_ROOT%
REM setup the path to the runtime files.
set path=%path%;%PEGASUS_HOME%\bin
In order to provide a consistent build structure across multiple platforms, we developed a small utility to provide a consistent set of small utilities across these platforms. The MU utility is a simple utility that contains many commands. For example:
C:\> mu rm myfile.cpp yourfile.cpp
You may type "mu" to get a list of valid commands. Here are some of them:
rm, rmdirhier, mkdirhier, echo, touch, pwd, copy, move, compare depend
The MU utility supports globing (expansion of wildcards) so you can do things like this:
C:\> mu rm *.obj *.exe
MU is required to build under the Windows environment. MU is
available as part
of the distribution of OpenPegasus.
Before using Pegasus you must populate the repository. Typically, this is done during the build process when you run the makefile. However, you can also do it manually after the Pegasus has been built.
The providers included with Pegasus are automatically entered into the repository by running the following command: make repository
The 'make repository' in the pegasus directory does three things:
Pegasus registers providers with a set of provider registration classes, not using the provider qualifier as is done in most DMTF CIM CIMOM implementations today. This set of classes is close to but not exactly the same as the experimental DMTF definition (See the DMTF Interop schema, experimental versions starting with 2.6). This will be harmonized in the future when the DMTF scheme is moved to final status.
Registration is performed by creating instances of the registration classes that represent the provider module, providers, classes, etc. to be registered. The easiest way to create a new registration today is to copy from one of the existing registration MOFs. See the providers/sample/load directory for examples of several registration instance implementations that do work with OpenPegasus today.
OpenPegasus includes an extensive set of test facilities as part of the CVS environment, including:
ICU (International Components for Unicode) refers to the set of
libraries that OpenPegasus uses to run globalized. For example: these
libraries are used
to
load messages in different languages, format currency and numbers
according to
a specific locale etc. In order to enable globalization in OpenPegasus,
OpenPegasus
must be built with ICU enabled, ie. the right environment variables
must be
set prior to running "make". Refer to the GlobalizationHOWTO.htm in the
docs
directory for details.
When users run "make poststarttests"
to verify the integrity of a OpenPegasus download, a series of tests
are
run that
require the cimserver to be running. These tests currently depend on
specific
messages returned from the server. When ICU is enabled, all messages
come from the resource bundles and these usually do not match the
hardcoded default messages within OpenPegasus. These hardcoded default
messages are what the various test programs expect in order to complete
successfully. If the ICU enabled server is started without
disabling message loading from the bundles, "make poststartests" will
fail.
In order to run "make poststarttests" successfully with ICU enabled, an
environment variable called PEGASUS_USE_DEFAULT_MESSAGES must exist
prior to
starting the server. Once this is defined, when the cimserver starts,
all
messages generated will be the default hardcoded messages. This will
enable
"make poststarttests" to complete successfully. Once "make
poststarttests" is
complete, you should stop the cimserver and then undefine
PEGASUS_USE_DEFAULT_MESSAGES. If this variable is left defined,
OpenPegasus
will not be able to load messages
using ICU resource bundles.
When running the make tests command with ICU enabled, the PEGASUS_MSG_HOME environment variable must be set to the home directory where the ICU resource bundles are built. By default the resource bundles are built into directories below PEGASUS_HOME/msg, so that should be the setting for PEGASUS_MSG_HOME.
Some of the steps of installing and running Pegasus have
security properties that you should be aware of. If you plan to administer a
Pegasus server, see the 'security considerations' section of the administrators
