HP DCE Measurement Service
Overview of DMS
DMS Prerequisite
You must install HP GlancePlus on the system where you intend to run DMS.
Enabling and Disabling DMS
DMS operates in three different modes:
•Disabled
•Inactive (the default)
•Active
You disable DMS by setting the environment variable DMS_FORCEOFF to any value and exporting the variable. (The software checks that DMS_FORCEOFF exists, not that the variable has any particular value.) DMS is also disabled when the
DMS is inactive by default. DMS is inactive when a DCE process is running, DMS_FORCEOFF is not set, there is no instance of HP GlancePlus executing, and the process euid is root.
DMS is active when a DCE process is running, DMS_FORCEOFF is not set, and at least one instance of HP GlancePlus is executing, and the process euid is root.
Performance Considerations of DMS
If DMS is installed on your system, but disabled, it has no significant impact on the system or on the performance of the server.
If DMS is inactive, there is no significant performance impact on the system.
When DMS is active, there is normally a performance decrease of less than 5%; in some cases, HP GlancePlus and swapping may cause a throughput decrease of greater than 5%.

DMS documentation, like HP GlancePlus documentation, is in the form of online
