Troubleshooting CHINIT statistics data

Checks to carry out if CHINIT statistics SMF data is not being produced.


Procedure

  1. Issue the display trace command. You need TRACE(S) CLASS(4) enabled for information about the CHINIT.
  2. If the trace is enabled, SMF data is written:

    • On a timed interval - depending on the value of the STATIME system parameter. A value of zero means that the SMF statistics broadcast is used. Use the DIS SYSTEM command to display the value of STATIME.
    • If the SET SYSTEM command is issued to change the value of the STATIME system parameter.
    • When the CHINIT is shut down.
    • If the STOP TRACE(S) CLASS(4) is issued, any statistics data is written out.
  3. SMF can hold the data in memory before writing it out to the SMF data sets or the SMF structure. Issue the MVS command D SMF,O and note the MAXDORM value. SMF can keep the data in memory for the MAXDORM period before writing it out.
