In Search Of Footprints

Chuck Hopf

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

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

What Has X Been Up To?

filename smf 'd:\mxgsmf\nov26smf.u' recfm=s370vbs; %smfsrch(lookfor=UXMCBH,nobs=10,USERADD=HSMDS/217 TMNT/238);

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

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)
