Log replay
The log replay process is responsible for the intraday writedowns from the RDB to the IHDB. It also does the EOD writedowns from the RDB and IHDB to the HDB. Writedown frequency is determined by setting the intraday frequency parameters in the LR and the TP.
- To create an LR, right-click on the Navigation panel in the
KxWarehousePackage and select New > Service Class from the context menu.
-
In Service Details, provide a description for the instance.

Configure the Service Parameters. The tables in the
intradayTableListshould match the ones configured in the TP section.
