Symptoms

Users are running the Demantra Batch Forecasting Engine. However it is encountering a severe performance problem and is not completing as tablespaces and logs are filling up rapidly. There are 19 million rows in Sales_data table when they were expecting only 250,000. On a separate laptop install, the engine runs in 17 minutes and completes successfully with similar data. When checking the data in the sales_data table in the laptop install there are only about 250,000 rows. Users state they only have 2 years of historical demand.


STEPS
1. Launch the batch forecast analytical engine
2. It hangs while inserting into the sales_data table
3. Review log file sizes and table sizes
