Modifying D-Series Applications for G-Series
Systems
The CTRL^DESC descriptor, which is used in D-series PVUs to identify
CONTROLLER entities, does not exist in G-series PVUs. It is replaced by the
SVNET^DESC descriptor, which identifies ServerNet addressable controllers (SACs).
However, you need not modify applications that include the CTRL^DESC descriptor if
the descriptor specifies all controllers or specifies only a CPU number. On systems
running G-series RVUs, the application measures all SACs. To identify a specific SAC,
you must use the SVNET^DESC descriptor and specify the SAC identifiers.
Applications that access Measure data files might need to be changed because of a
change for G-series RVUs in ERROR field values. The ERROR field can now return a
value of -1, indicating that there is data in the record but one or more fields overflowed.
If an application tests for the presence of data by checking for a 0 (zero) value, you
must change the application to check for either 0 or -1.
