Deleting old database records

The number of data records in the tables grows over time, and depending on the amount of storage space available, from time to time, you might want to remove data manually to maintain the tables at a smaller size. After you clear the CHANGE_HISTORY_TABLE, you can remove the corresponding entries in the CHANGE_CAUSE_TABLE. You can also improve performance and usability of the data integrity tool by deleting old records from the ALIASES_JN table.
