  • 1.  Data Set Refresh Time

    Posted Fri June 17, 2022 10:49 AM
    I am using a couple of data sets behind some reports.  A database view is the source to those data sets.

    The data sets have scheduled to refresh every day in the morning.  The below fig 1 is the snap shot of the data sets run time part of a scheduled job.  It shows a data set takes time around 10 minutes and other one does 12 minutes.  Whereas fig 2 shows actual time taken to refresh each data set thru its properties.  They show max 4 minutes.  In this case, why does the schedule always takes around 12 minutes to complete?  Is there any other factor for the cause ?  Could anyone help me to understand?

    Please let me know if you have any questions.

    We have similar observation in our Cognos Analytics 11.1.7 environment. Did anyone come across an explanation for this?

    Thanks in advance.

    Hi Karthikeyan,

    If you are having such issues, I would suggest you open a support call if you haven't already, they would help you to find a real explanation about this issue.
