Hi, We implemented UNDO management on our servers and started getting these errors for few of our programs:=20 ORA-08176: consistent read failure; rollback data not available=20 Per Oracle9i Database Error Messages reference: Cause: Encountered data changed by an operation that does not generate rollback data: create index, direct load or discrete transaction.=20 Action: In read/write transactions, retry the intended operation. Read-only transactions must be restarted. We did not encounter these errors when we were using the old rollback segments and we have not changed any code on our server.=20 Our environment is Oracle 9.2.0.5.0 DB on Windows 2000 AS. Any inputs/suggestions would be great. Thanks and regads Shreepad=20 -- //www.freelists.org/webpage/oracle-l
