PK97285: DIAGNOSTICS TRACE ENHANCEMENT FOR PE SERVER SUBTASK

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• This solution is to generate additional diagnostics data which
  will help to analyze SVC dumps with the titles
  having the keywords 'INCORRECT RA', 'INCORRECT DPM0', 'HIGH CPU'
  in their titles. These dumps are produced by PE Server subtask
  when a corresponding problem comes up.

  PROBLEM SUMMARY:
  This solution is to generate additional diagnostic data which
  will help to analyze SVC dumps with the titles containing the
  keywords 'INCORRECT RA', 'INCORRECT DPM0', 'HIGH CPU' in their
  titles. These dumps are produced by PE Server subtask when a
  corresponding problem comes up.
  
  For V420: FFit of V410 APAR PK87487
  During initialization of the Snapshot History Manager an already
  existing Snapshot History data set is read to build the table of
  contents. When corrupted data are read, the processing of the
  data can cause an ABEND S0C4 in load module DGOVHM00. The PE
  Server subtask tries to recover once and therefore restarts the
  Snapshot History Manager. The same corrupted data are read again
  and cause the same ABEND S0C4.

Problem conclusion

• This solution is to generate additional diagnostic data which
  will help to analyze SVC dumps with the titles containing the
  keywords 'INCORRECT RA', 'INCORRECT DPM0', 'HIGH CPU' in their
  titles. These dumps are produced by PE Server subtask when a
  corresponding problem comes up.
  
  For V420: FFit of V410 APAR PK87487
  When the Snapshot History data set is read, the data are checked
  for consistency before they are processed to build the table of
  contents. When inconsistencies are detected, the Snapshot
  History data set is renamed and a new Snapshot History data set
  is allocated to continue the collection of Snapshot History
  data.
