5.2.7 IMS Application Unit Activity File-Fast Path (IMS_IA)

The placement of observations is dependent only on the data
source used and the scheduling mechanism involved.

|                                    |      DATA SOURCE     |
|       SCHEDULING MECHANISM         |----------------------|
|                                    |    IMF    |  NON-IMF |
+-----------------------------------------------------------+
|  EMH (Expedited Message Handling)  |  IMSIAU   |  IMS_IA  |
+-----------------------------------------------------------+
|  Non-EMH (Message queue or BMP)    |  IMSIAU   |  IMSIAU  |

NOTE:  If the NOFP option is specified in
       prefix.MICS.PARMS(IMSOPS) or in the LDEPARM data set,
       then transactions scheduled by the EMH will not be
       collected in the IMS_IA file.

The following sections describe the file's organization, list
the data elements maintained, and provide usage hints.
