Convert short-term history files to delimited flat files
If you selected the option to store data to a data base, that option is mutually exclusive with running the file conversion programs described in this section. To use these conversion procedures, you must have specified Off for the Warehouse option in the History Collection Configuration window of the Tivoli Enterprise Portal.
The conversion procedure empties the history accumulation files and must be performed periodically so that the history files do not take up needless amounts of disk space.
For every ATTRIBUTEGROUPNAME that you plan to use with the krarloff program or itmcmd history, first stop historical collection for that attribute by either using the tacmd histstopcollection or the History Collection Configuration window in the Tivoli Enterprise Portal.
Corruption of the data can occur if both programs, the historical collection and the krarloff program, try to access the data at the same time. Stopping the historical collection ensures that the saving and roll off of the data cannot be done simultaneously.

The krarloff rolloff program can be run either at the Tivoli Enterprise Monitoring Server or in the directory where the monitoring agent is running, from the directory in which the history files are stored.
