PEP#: 9999
TITLE: add wsm

DESCRIPTION: add wsm components

For the demo, we need class level information within the wsman
conversions but do not have things like xsds, access to xsd 
repositories, etc.  The pegasus repository was a logical source
of this information.  

So, we extensivly use the pegasus repository with getclass to
crete meta-information about classes.  This assumes that we can
access a pegasus repository even for instance operations.

When working with Pegasus that is easy since Pegasus is always
available. We assume that the address of the wsman server and 
the source for class information are the same.

However, when working with other wsman servers both the client aps
and internal implementation need access to this information so
for the demo we set up a way that we can have one address for
the wsman server and a second address representing the pegasus
server which will be used for class operations and for getting
any class level information needed by the client.

To use this, set the following Environment variable before starting
any client

WSM_PEGASUS_HOST
and
WSM_PWGASUS_PORT

Thus

export WSM_PEGASUS_HOST=localhost
export WSM_PEGASUS_PORT=5988

When the WSM_USE_WSMAN=true environment variable is set, the WSMCLI client
sends instance operations to a wsman destination and both api driven class
operations (ex. getClass) and background class operations to the PEGASUS Host
defined. This means the the host and port specified on the CIMCLient   connect
call (the -n option with CLI)  represent:

1. the cimxml cimserver when WSM_USE_WSMAN is NOT set.
2. The wsman server for all instance operations and ignored for class
operations if WSM_USE_WSMAN is set.

The defaults for server addresses are applied as follows:

cimxml server address:

    localhost:5988

wsmanserver address

localhost:<<value in defines.h>> (port 80 for the demo)

Thus, The cli -n options specifies the WSM host and port for instance operations
when the WSM_USE_WSMAN=true flag is set and the cimxml host when the
flag is not set.

NOTE: The code today DOES NOT allow the port 5988 to be used as the port for
the wsman server.  If you do use that address, it will cause problems.

Thus, some examples that work:

export WSM_PEGASUS_HOST=hostb
export WSM_PEGASUS_PORT=5988

cli ni CIM_Computersystem -l hostb:5988

    will access the cimxml server with cimxml address

export WSM_USE_WSMAN=1

cli ni CIM_ComputerSystem -l hostb:80
   
   will access the wsman server on hostb at port 80
   Note that it will also get class info from the Pegasus server
   defined in the exports above.

cli ni CIM_ComputerSystem -l hostb
