You might try running hot backups at the OS level instead. It sounds like your export is just taking too long. To get it to work with active users on board you might have to increase your rollback segments to truly ridiculous levels especially if you have large batches running while the export is running. To really understand the issue go to http://www.ixora.com.au and look at Steve Adams' material on snapshot too old.
Allan -----Original Message----- Sent: Friday, February 21, 2003 4:00 AM To: Multiple recipients of list ORACLE-L Hi all I have a problem when doing an export in one of ourt production databases. The export fails with ORA-01555, snapshot too old error. I have increased the number of rollback segments and their sizes on the database. Also I have went to an extent of specifying the parameter constent=n on my script but backups fails. The worst part is this export runs for a long time and then fails, more than 24 hours. The only time that this export succeed is over the weekend, because most of the time few people are working or not at all. Now I have tried to start it after hours but as I said it still takes long and end up failing the next day. Could somebody help me here, this is very critical to be running production without proper backups .....!
