We have a query that began taking a long time about a week ago. The program, in SAP, ran for 10 - 15 minutes but is now taking about 6 hours. The table has 5.1 million rows. The explain plan shows a simple index range scan. We just reran statistics on the table and all indexes but no luck We are concentrating on the one query that took about 4.75 hours. Does anyone see something glaring or know of a simple test to locate the problem? Let me know if you need any other info. Thank you, William B.
