Hi, Viktor,
Have any long transactions been running parallel to the export when it happened?
And do you specify the parameter CONSISTENT=Y for the export? Regards,,

Hi all,

Last nignt when we were expring data for one of our databases, this error ocurred:

ORA-01555: snapshot too old: rollback segment number 3 with name "R02") offset=(0).

Now, we were able to once again export and load data this morning. And there was no error.

What is the best aproach to try to eliminate this error in the future?

Any suggestions apreciated.

Thanks

Regards
