Creating the summary activity report

The SMF data set dump program creates a summary activity report when the DUMP option was specified for any of the input data sets and at least one record was read or written.

Table 1 shows an example of the summary activity report the SMF data set dump program creates. The meaning of each heading is:

START DATE-TIME indicates the date and time of the earliest record read, excluding record types 2, 3, and those greater than 127. Under most circumstances this date and time will not equal the date and time of the first record written.
END DATE-TIME indicates the date and time of the latest record read, excluding record types 2, 3, and those greater than 127. Under most circumstances this date and time will not equal the date and time of the last record written.
RECORD TYPE indicates the identifying number of each record type read by the SMF data set dump program.
RECORDS READ indicates the number of input records read for each record type.
PERCENT OF TOTAL indicates the number of records read for each type divided by total number of records read.
AVG RECORD LENGTH, MIN RECORD LENGTH, and MAX RECORD LENGTH indicate, respectively, the average, minimum, and maximum lengths of the records read for each record type.
RECORDS WRITTEN indicates the number of output records written to the output data sets as specified by the SYSIN parameters.
TOTAL indicates the total activity for each column.
NUMBER OF RECORDS IN ERROR indicates the number of records that were not dumped because of errors. There are two types of errors:
1. Incorrectly-spanned records cannot be read. (A spanned record is larger than the control-interval size of the SMF data set.) These records may be encountered if a physical I/O error occurred on a recording data set while a spanned record was being written. The SMF data set dump program is unable to read incorrectly-spanned records.
2. Incorrectly-formatted time or date values in record-header fields prevent processing of the record. The record is read but not written or processed. If your installation writes user records (record types ranging from 128 through 255), see Standard SMF record header for a description of the proper header format.
If there are any records in error, the INDD-name or LSNAME-name, type of error (INVALID TIME OR DATE or INCONSISTENT SPANNED RECORD), record sequence number, and the first 32 bytes of the record (in error) are printed. This processing is performed only for the first 500 records in error of each SMF recording data set. When more than 500 records in error are found, the SMF data set dump program writes message IFA024I to the SYSPRINT data set. Subsequent records in error are not printed, but are counted in the total number of records in error. The record sequence number is the sequential number of the record in the INDD.
