Clear the data from the RAPCache on a regular schedule.
Use Interactive SQL (isql) to run the script truncate_cache_TAQ_tables.sql.
The script truncate_cache_TAQ_tables.sql is located in the $RAP/RAPCache/datamodel/scripts directory. It clears the data by truncating the STOCK_TRADE and STOCK_QUOTE tables in the RAPCache.
If errors occur during the truncate process, a message is displayed and error messages are written to the file truncate.err.
