Commit statements attempted and Rollback statements attempted-see Tip 3 ). After the second command is issued, the number of rows read is divided by the number of transactions (RowsPerTX ). In each transaction, OLTP applications should generally read 1 to 20 rows from each table. If you find that hundreds of rows are being read for each transaction, you may need to create an index when scanning. (Sometimes running runstats with distribution and detailed indexes also provides a solution .) 1 g
