Install the following JCL in SYS1.PROCLIB to allow the data set ENQ contention monitor to be started from the operator console:

  //ISGECMON PROC INTERVAL=60
  //ISGECMON EXEC PGM=ISGECMON,PARM='&INTERVAL'
  //*
  //*  Invoke from console with
  //*       START ISGECMON
  //*  to have the program scan for contention
  //*  every 60 seconds.
  //*
  //*  Optionally, invoke from console with
  //*       START ISGECMON,INTERVAL=ssss
  //*  where ssss is the number of seconds (in decimal)
  //*  to pause between scans.
  //*
