I have a system with many INSERT and UPDATE. Use STORE PRCEDURES which increases the LOG in the database. Each time the file of LOG is nearing the end of the stipulated value, can not implement more INSERT and UPDATE, or my system STOPS. I have always to increase the file of LOG to use my system. I have been with 100MB of LOG every month and must increase, because there is a way to clear the LOG. I think the HSPHERE have a problem on that, or who knows, it should clear the LOG when it reached some 10% of the final, or someone you know any other solution?
