IV62216: VALIDFROM DOES NOT SELECT THE DAY CORRECTLY HAVING 2 JOB STEAMS WITH THE SAME NAME AND -1 WORKDAYS

APAR status

• Closed as program error.

Error description

• Environment:
  MDM: TWS 8.5.1 GA
  
  Replication steps:
  1. Define a calendar with the first of the month.
  ONEDAY
    "First of the month"
  09/01/2013 10/01/2013 11/01/2013 12/01/2013 01/01/2014
  02/01/2014 03/01/2014 04/01/2014 05/01/2014 06/01/2014
  07/01/2014 08/01/2014 09/01/2014 10/01/2014 11/01/2014
  12/01/2014
  
  2. Define 2 job steams with the same name and validfrom.
  The later validfrom is defined on the day which is calculated
  as "ON" day with -1 WORKDAYS.
  
  Calendar ONEDAY : 06/01/2014.
  Since May 31 is Saturday, "06/01/2014 -1 WORKDAY" is  May 30.
  
  SCHEDULE DR851#JSVALIDFM VALIDFROM 01/10/2014
  ON RUNCYCLE RULE1 ONEDAY -1 WORKDAYS
  :
  DR851#JOB001
  END
  
  SCHEDULE DR851#JSVALIDFM VALIDFROM 05/30/2014
  ON RUNCYCLE RULE1 ONEDAY -1 WORKDAYS
  :
  DR851#JOB002
  END
  
  3. Confirm on Run Cycle Preview that May 30 is not selected as
  a planned date.
  
  
  OK case 1:
  June 1 is selected as plan day correctly.
  
  Calendar day: 06/01/2014
  SCHEDULE DR851#JSVALIDF1 VALIDFROM 01/10/2014
  ON RUNCYCLE RULE1 ONEDAY
  :
  DR851#JOB001
  END
  
  SCHEDULE DR851#JSVALIDF1 VALIDFROM 06/01/2014
  ON RUNCYCLE RULE1 ONEDAY
  :
  DR851#JOB002
  END
  
  OK case 2:
  May 31 is selected as plan day correctly.
  
  Calendar day: 06/01/2014
  "06/01/2014 -1 DAYS is  May 31.
  
  SCHEDULE DR851#JSVALIDF2 VALIDFROM 01/10/2014
  ON RUNCYCLE RULE1 ONEDAY -1 DAYS
  :
  DR851#JOB001
  END
  
  SCHEDULE DR851#JSVALIDF2 VALIDFROM 05/31/2014
  ON RUNCYCLE RULE1 ONEDAY -1 DAYS
  :
  DR851#JOB002
  END
  
  Note:
  The issue occurs if the first day of the month is Saturday or
  Sunday.
  

Local fix

• Define a specific job steam to run on the missing day.
  

Problem summary

• The issue occurs in this case:
  - define a calendar with a set of days
  - define a runcycle that uses the calendar and has the rule
  "Offset: -1 WORKDAYS"
  - define a JOBSTREAM that uses the RUNCYCLE and has a VALIDFROM
  value
  If the VALIDFROM value coincide with one of the calculated
  runcycle instances than that instance is not used.
  E.g.
  Set the calendar defined on the day 01/06/2014, called CAL1
  Set a runcycle RC1 that uses CAL1 with the OFFSET -1 WORKDAYS
  Set the JobStream JS1 with VALIDFROM 30/05/2014.
  The RUNCYCLE is calculated as 01/06/2014 - 1 WORKDAYS that
  should be 31/05/2014. But the 31/05/2014 is sunday so
  30/05/2014 is taken.
  The value 30/05/2014 is the same as the VALIDFROM value. In this
  case TWS is excluding that runcycle instance.
  
  Managing the case in which the runcycle instance coincide with
  the validfrom.
  

Problem conclusion

• This apar will be fixed  8.6.0-TIV-TWS-FP0005,
  8.5.1-TIV-TWS-FP0006, 8.5.0-TIV-TWS-FP0006 and
  9.1.0-TIV-TWS-FP0002, 9.2.0-TIV-TWS-FP0002.
