Detail line descriptions

EXCP counts

Each detail line shows the following information.

Under Heading This is Displayed
DDNAME The DDNAME of the file. If multiple OPENs occurred for the DDNAME, a separate line is reported for each "instance." A sequence number is appended to the DDNAME indicating the instance.
Type The type of file (VSAM, Non-VSAM, Tape, etc.)
Concat The concatenation number. A value (+0, +1, +2 ...) appears here to indicate the data set position in a concatenation.
At Start The EXCP count for the data set when first observed. For VSAM data sets, the system maintains this count for the life of the file. For non-VSAM, this only reflects EXCPs during the step.
At End The EXCP count for the data set when last observed. For VSAM data sets, the system maintains this count for the life of the file. For non-VSAM, this only reflects EXCPs during the step.
During Measurement The number of EXCPs for the measurement duration. This is computed as the difference between the "At Start" count and the "At End" count.
Note:
The system maintains EXCP counts at the data set level. If a data set had more than one file open concurrently under different DDNAMEs, then overlapping EXCP counts will be reported.
