PM82770: SEE AN INCREASE IN THE NUMBER OF UNCOMMITTED UR INCIDENTS BEING GENERATED IN FM/DB2 V12.1 VS. V11.1

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Client sees an increase in the number of  Uncommitted UR
  incidents being generated by queries being run when viewing DB2
  table data using File Manager V12.1
  

Local fix

• 1. This issue can be avoided by turning off the 'Read-only
     access' option on the last editor options panel (7/7).
  
  2. Even with the change that will be made in the APAR, DSNU035I
     messages may be issued for a customer using FM/DB2 edit
     (not view or browse) in 'Large table' mode (row count = 0,
     ALL, *).
  
     These messages will not be issued unless the user has the
     'Read-only access' option selected.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of File Manager DB2 component.     *
  ****************************************************************
  * PROBLEM DESCRIPTION: DB2 issues DSNR035I messages under some *
  *                      circumstances, caused by File Manager   *
  *                      DB2 component editor sessions.          *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  Certain combinations of File Manager editor options can result
  in fetches against DB2 data using "uncommitted read", without
  a COMMIT after the initial data fetch.  This can lead to DB2
  issuing DSNR035I messages after a DB2-installation-dependent
  delay.
  

Problem conclusion

• The File Manager DB2 component editor has been changed as
  follows:
  1. For browse and view, always issue a COMMIT after the initial
  data fetch, regardless of the editor's operating mode ("normal"
  or "large").
  2. For edit sessions in "large" mode, issue a COMMIT after the
  initial data fetch when the "Commit after data fetch" is
  selected.
  3. Display a warning panel for any edit session where the
  editor options include "Uncommitted read" and no "Commit after
  data fetch".
