If the change protocol request is from DCOM to HTTP, the simple installer component receives a request
to install the ComSocketServiceListener.
It the change protocol request was from HTTP to DCOM, the simple installer receives a request to remove
the ComSocketServiceListener.
The simple installer does not modify the contents of the installation infrastructure. The simple installer job
is only used to initially deploy the infrastructure using the Registration service as a bootstrap loader.
Beacuae the simple installer job cannot take action on the information it receives, it delegates the work to
the Install Module Installer step.
Store Installation Data in the Database
The store installation data in the database process updates the list of modules in the database.
Install Module Installer
The install module installer action reconciles the information regarding what infrastructure modules are
installed, whether to install or remove the ComSocketServiceListener, and determine the actions to
run.
If you are switching from DCOMto HTTP and the ComSocketServiceListener should be installed, the
install module installer creates a request and sends the work of installing this module to the Registration
Service.
If you are switching from HTTP to DCOM and the ComSocketServiceListener should be removed,
the module installer creates a request and sends the work of uninstalling this module to the Registration
Service.
Fully Release the Synchronization Lock On the Target Machine
The fully release the synchronization lock action clears the runtime Agent lock. Clearing the Agent lock
allows the VCM Agent to inspect the target Windows machine.
1. A connection is made to the module installer.
2. Unlock is called.
Submit Request to Agent
The submit request to Agent action is the first VCM Agent inspection on the Windows machine.
After installing the Agent, a machine environment inspection is performed.
Check If Request Is Complete
The check if request is complete action verifies that the Collector successfully collected from the VCM
Agent on the Windows machine.
The Collector checks to determine if the Windows machine environment collection from the Agent is
complete.
Transfer Request Results
The transfer request results action sends the results of the inspection on the Windows machine to the
Collector as part of the change communication protocol process.
After the Agent completes the machine environment inspection on the Windows machine, the results are
sent back to the Collector.
