About the ARM_OMA Subsystem
Application Response Measurement (ARM) is a standard for managing the
performance of distributed applications. The ARM_OMA subsystem of the SAS
Metadata Server uses ARM API calls to return detailed log entries when the following
events occur:
3 A SAS Open Metadata Interface method is started.
3 Certain metadata server functions are started.
3 An XML request is issued.
3 One of the following subtransactions occurs:
3 An association is added, retrieved, or removed.
3 An association overwrites an existing association.
3 A list of metadata objects is retrieved.
3 A SAS Open Metadata Interface method, function, or XML request is stopped.
The ARM_OMA log entries are useful for performance analysis and basic method call
debugging. For more background information about the ARM system, see "Monitoring
Performance Using Application Response Measurement (ARM)" in SAS Language
