Collection Details Of Driver

Message Counters

 Environment: 
At both the start and end of collection, the driver records the non-keypointed control program message counters (high speed processed, low speed, high speed routed, and created entries message counts), and the system message counters (program entry counters maintained by UII).

 Effect: 
Because these are non-keypointed counters, the driver will record zero message counts if data collection is abnormally stopped because of a system failure.

One-Time Driver Records

 Environment: 
At the start of collection, the driver records on the RTC tape contain various configuration defining records.

 Effect: 
Provides reduction programs with data needed to reference configuration dependent arrays.
