Error description

  • After upgrade of the federated database, NNSTAT on DRDA
    nicknames may fail with SQL0181N "The string representation of a
     datetime value is out of range"   or  SQL0180N: The syntax of
    the string representation of a datetime value is incorrect.
    
    The problem starts to happen on V97FP9, it is a regression of
    APAR JR47912.
    
    To reproduce:
    
    1.  On data source:
    CREATE TABLE DB2INST1.TT(C1 INT)
    RUNSTATS ON TABLE DB2INST1.TT ON ALL COLUMNS AND INDEXES ALL
    ALLOW WRITE ACCESS
    
    2.  On Federated server:
    
    create wrapper drda
    create server serv type DB2/UDB version 9.7 wrapper drda
    authorization "<userid>" password "<password"  options(dbname
    '<db name>')
    create user mapping for <user id> server serv
    options(remote_authid '<remote userid>', remote_password
    '<password>')
    create nickname db2inst1.nn for serv.db2inst1.tt
    
    
    =>  db2 "CALL
    NNSTAT('SERV','DB2INST1','NN','/tmp/stat.txt',?,?)"
    SQL20274W  Some of the nickname statistics cannot be updated.
    
    => cat /tmp/stat.txt
    Start log...
    
    
    Processing nickname "NN".
    
    An attempt to create a nickname on table "DB2INST1 .NN_DB2II"
    failed. An error was returned when executing the CREATE NICKNAME
    statement.
    
     Could not read the remote stats time properly
    nnstat.SQC, Line 4278 : SQL0180N  The syntax of the string
    representation of a datetime value is incorrect.
    
    With this fix, you may recreate nickname whose stats time might
    be some incorrect format.
    

Local fix

  • Use NNSTAT with method 2.
