Obtaining SMF dump data sets

In order to use this tutorial in an interactive manner, you will need access to at least one, but preferably more than one, SMF dump data set containing zERT Summary (type 119, subtype 12) SMF records.

If you do not already have SMF dump data sets with zERT Summary records, take the following steps to obtain the necessary SMF dump data sets:
  • If you have not already enabled zERT aggregation, enable the function. You must also enable collection of zERT Summary (SMF 119 subtype 12) SMF records to the System Management Facility (SMF). For more details, see Enabling zERT aggregation and zERT Summary record (subtype 12) in IBM® Knowledge Center.
  • After zERT aggregation and zERT Summary SMF record collection has been enabled, collect one or more SMF intervals of record data.
    Note: You can collect the records into more than one SMF dump data set in order to get the most out of using the tutorial interactively.
  • Format the collected SMF records to an SMF dump data set or SMF dump stream.
    • If you are dumping the SMF records to an SMF data set, the records must be dumped to the data set using the IFASMFDP program.
    • If you are dumping the SMF records to an SMF log stream, the records must be dumped to the data stream using the IFASMFDL program.
Note: The SMF dump data sets you plan to use must be cataloged and accessible to z/OSMF, and the user ID under which z/OSMF runs must have permission to read the data sets.
