How to set the duration of the DW collection task

0
Hehui Liu (70●5●28●30) | asked Aug 08 '12, 5:17 a.m.
Here, we are using some of the RTC reports, but the data comes from dataware house, and default, the duration of the DW collection task is one day. Does there any way to tune the duration? Or could we trigger the collection task by a program? Thanks a lot!

There is a "Task delay"  property which is set to 86400=24*60*60 , I guess this is the time interval. If you set to 60*60=3600, it is gonna run every hour.

Thanks Canberk, as my understand, in the link you provide, we just only could set at which time in one day, the data collection task should be executed, but it can not set how long the data collection should be executed, for example, every 4 hours. Pls correct me, if it is wrong.

There is a property which is set to 24, if you change it to 4, it will execute at 4 hours intervals i believe :) I am not sure :)

I dont have connection to my prod server that's whhy I am guessing right now.

I believe that number is not an interval but an hour of the day when the jobs are run. At least that's what I gather from http://pic.dhe.ibm.com/infocenter/clmhelp/v4r0/topic/com.ibm.rational.reporting.admin.doc/topics/t_running_the_data_collection_jobs.html
as well as the tooltip text when hovering over the "Data Warehouse Snapshot Time" property at https://vhost0585.dc1.on.ca.compute.ihost.com:9443/jts/admin#action=com.ibm.team.reportsManagement.configureDataWarehouseConnection:
Choose a value between 1 and 24 (hours). All the scheduled daily snapshots will run at the chosen hour.

It is highly discouraged to set the interval to less than 24 hours as doing so will impact performance and increase significantly the size requirements of the data warehouse. Most of our scrum reports (Burndown, Burnup, Release Burndown) will display a live point to display an up to date chart.
