0 - 3 of 3 tags for lastaccesstimestamp

I have come across a strange situation. I have a view which points to a Global temporary table. There is a daily process that runs a macro to insert data into the view and then use it for select query Joins.
 

In our TD system the ObjectUseCountCollectRate values is set to 10(default value in 14.10), but the DBC.Objectusage table is not updated. the table is empty.
The lastaccesstimestamp and access counts has only NULL vaules in DBC.tables.
Please help me to resolve the issue. The lastaccesstimestamp would help me to a great extent.

I want to modify the ObjectUseCountCollectRate but I need to know if it requires a DBS restart after the MODIFY and WRITE.
 
Anyone know?
