GFTAXTR Output Report—Final Record Output Phase

Figure 1 is an example of part of the GFTAXTR output report that shows SMF record output statistics. These are the records that are input to GFTAVMA.

35 This shows the system identifiers for the systems you are studying in the SMF sample. Systems in a run must all belong to the same logical complex with shared access to the tape subsystems being analyzed. See Understanding the Limitations of the Volume Mount Analyzer for shared systems considerations.

After you run GFTAVMA, make sure that the system IDs and the date and time on this GFTAXTR report match the system IDs and date and time on the GFTASRT1 summary report. See GFTASRT1—Input Analysis Report.

36 GFTAXTR has taken the original SMF data, extracted only the parts necessary for the analysis, and compressed the data. These statistics reflect the efficiency of this process. In this example, the output from GFTAXTR uses only 25.2% of the storage that the original SMF data would have used.

37 Data set open records do not always correlate with previous processing phases because in some cases a data set can have more than one open record. See Open Counts for more information.

38 GFTAXTR creates its own internal record types. The counts of these records match the counts of the similar type SMF input records that were not dropped. But the format of these records is different from that of the SMF records. GFTAXTR has indexed data set and demount records to one another and added job flow information so that GFTAVMA can get an accurate picture of the jobs that created the data sets.

Because of GFTAXTR's data compression, the total number of output records is smaller than the total in Figure 1.

39 Ideally, the return code is 0. However, the return code is usually 4 because GFTAXTR generates warning messages to tell you the time and reasons that SMF records were dropped or altered. Missing information in the input SMF records caused these warning messages. Normally, the missing information only represents a small percentage of the total SMF input and does not affect the analysis. See Volume Mount Analyzer Messages.
