The Oracle HMP tool, hwmgmtcli, might not work after Windows 2008 SP2 and Windows 2008 R2 installation. When hwmgmtcli is called, the following error message appears:
This application has failed to start because hwmgmtcommon.dll was not found. Re-installing the application may fix this problem.
The Oracle HMP agents are not installed unless the SNMP agent is installed first. SNMP must be installed before installing the Oracle Hardware Management Agent.
