APAR status

  • Closed as program error.

Error description

  • Intermittent -901 instead of expected -910 are possible when
    running ALTER SQL statements and
    commits are not done by the application as expected.
    
    In sql where user should commit immediately after the ALTER SQL
    statement, if that is not done,
    SQL910N  should be returned. However sometimes SQL0901N is
    returned and FODC directory is created.
    This is wrong.
    
    db2diag.log will have:
    
    FUNCTION: DB2 UDB, data management, sqldSeqFetchUpdateGen,
    probe:3038
    MESSAGE : ZRC=0x82040001=-2113667071=SQLD_NONSEVERE_PRGERR
              "non-severe dms programming error"
              DIA8532C An internal processing error has occurred.
    DATA #1 : String, 38 bytes
    DTS mismatch between request and cache
    DATA #2 : String, 21 bytes
    

Local fix

  • Do:
      execute immediate 'alter table  <tablename> alter column ...
      commit;--
    
    As expected
