DFS3413X INVALID CONTENTS IN THE MODSTAT DATA SET

Explanation

The MODSTAT data set contains invalid data.

The MODSTAT data set must contain the following fields in such order: 
modifyid,MODBLKSx,IMSACBx,FORMATx
Values must be separated by commas, with no imbedded blanks.
modifyid
The MODSTAT identifier number, which is variable length with no limit. This field is usually initialized to 1.
MODBLKSx
The ddname for the active MODBLKS data set, either IMS.MODBLKSA or IMS.MODBLKSB data set that contains the IMS system definition output. . This field is usually initialized to MODBLKSA. You must define the MODBLKSx field even for an IMS system that does not define the MODBLKS data sets.
IMSACBx
The possible values for the data set suffix xare A and B.
FORMATx
The possible values for the data set suffix xare A and B. This field is usually initialized to FORMATA. You must define the FORMATx field even for an IMS DBCTL environment that does not use the FORMAT libraries.
Note: For more information on the fields, see Initializing the IMS.MODSTAT data set.
If at least one online change has been successfully committed, these fields are followed by an online change prepare timestamp and an online change commit timestamp in the following format: YYYYDDD HHMMSS offset. In the timestamp:
  • YYYY - the year
  • DDD - the Julian day
  • HH - the hour
  • MM - the minutes
  • SS - the seconds
  • offset - the UTC time offset in the format -xx:xx or +xx:xx
Note: The timestamps, if applicable, must be in the correct format to avoid IMS restart failure.
The following example shows the values of a valid MODSTAT data set: 
108,MODBLKSA,IMSACBA,FORMATA 2016099 191653 -07:00 2016100 041751 -07:00

System action

IMS terminates abnormally with abend 3413.

Programmer response

Check the MODSTAT data set content to ensure that the modifyid, the online change fields and the timestamps are in the correct format.

If this message is issued because of an error in the modify identifier number or the online change fields in the MODSTAT data set, use the INITMOD procedure to correct the error and retry.

If this message is issued because of an error in the timestamp in the MODSTAT data set, use the Time Sharing Option (TSO) to correct the error and retry.

In other cases, reconstruct the MODSTAT data set, using the INITMOD procedure with the ddnames indicated on the last successful DFS3410I, or DFS3499I message, and run IMS.
