Name : Service_Services
|
|
|
|
Description : Handler program for all module related services.
|
|
|
|
Notes : Service module to support environmental state issues. Environmental refers to the state of the
|
|
operating system, which includes version, client vs. server, and path to critical systems.
|
|
|
|
Parameters :
|
|
Service [in] -- Name of the service being requested
|
|
Param1-10 [in/out] -- Additional request parameter holders
|
|
Response [out] -- Response to be sent back to the Controller (MCP) or requesting procedure
|

History : (Date, Initials, Notes)
|
|
02/06/18 dmb Original programmer.
|
|
07/25/18 dmb Update the GetServices service to pick services without any assigned servers. This is to
|
|
allow a service to be ran against any server.
