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".
