Error description
After the BACKUP CFSTRUCT command and a subsequent DISPLAY CFSTATUS TYPE(BACKUP) execution, it is possible to see that the BKUPTIME contains a time 30 seconds prior to the execution of BACKUP CFSTRUCT command. IBM MQ Development: z/OS Service team has been able to determine that this occurs because the value of field is incorrectly set from the backup cut-off time that is used to determine the messages that are backed-up. This field is therefore influenced by the EXCLINT value which is used to specify the number of seconds that are used as an exclusion time. The default value of this parameter is 30 seconds which means the backup would not include the last 30 seconds worth of activity for this application-structure before back up started. This would also explain why the value of the BKUPTIME was exactly 30 seconds prior to the BACKUP CFSTRUCT command. This field should instead represent the 'end time of the last successful backup taken for this application structure.'.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM MQ for z/OS Version 9 * * Release 2 Modification 0 and Release 3 * * Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: After issuing a BACKUP CFSTRUCT * * command immediately followed by a * * DISPLAY CFSTATUS command, the BKUPTIME * * field incorrectly contains a timestamp * * prior to the execution of BACKUP * * CFSTRUCT command. The amount by which * * the timestamp is before is influenced * * by the EXCLINT value specified when * * the BACKUP CFSTRUCT is issued. * **************************************************************** The code which handles the BKUPTIME field incorrectly assigns the wrong timing variable.
Problem conclusion
The code has been changed to assign the correct timing variable so that the BKUPTIME field now displays the end time of the last successful backup taken for the structure.
