  1. In Search Of Footprints Chuck Hopf

  2. The Worst or Funnest Part of the Job • Managing Capacity is OK but getting boring • Not nearly the challenge it once was • Managing Performance is tedious with WLM • How much can you change? • Finding the footprints in the sand is much more interesting • We are the SMF ‘experts’ • Everything (well almost everything) on a zOS system leaves footprints

  3. Common Questions • Who deleted/updated/renamed my dataset/PDS member? • Ask not for whom the bell tolls… • What has person X been doing on the system? • X was caught doing something naughty and management wants to know everything they touched

  4. What Has X Been Up To? filename smf 'd:\mxgsmf\nov26smf.u' recfm=s370vbs; %smfsrch(lookfor=UXMCBH,nobs=10,USERADD=HSMDS/217 TMNT/238);

  5. What Has X Been Up To? • SMFSRCH in MXG 29.07 • Reads all SMF data and finds and identifies by type and subtype what records were found and copies them to another file • Reads the copied records including as many user records as are defined to MXG • Prints a report of all TYPEs/SUBTYPEs found • Prints a report of all SAS datasets created • Prints the detailed records for all SAS datasets created

  7. SMFSRCH • LOOKFOR could be • A USERID • A dataset name • A volser • A db2 subsystem name • Most anything you can think of so long as it is alpha (if you specify numerics it will generate an alpha search so if you were looking for a packed or binary number it would never match)
