Attention: To align with new corporate security policies, and to match policies adopted by other communities within Oracle, the My Oracle Support Community access requirements will change beginning September 18, 2025. MOSC will now require that member accounts in our community be associated to a *corporate* email address. This means that users with generic domains (such as gmail.com, yahoo.com, and others) will no longer be granted access to the discussion forums and ideas labs. If this policy affects you, act now to change the email address that is associated with your Oracle (and community) account. Alternatively, you can opt to create a new Oracle account that uses your corporate email domain.

EXPDP Causes ORA-01555 Snapshot too old Rollback segment too small

Aug 7, 2009 6:51AM edited Oct 8, 2009 3:52AM in Database Utilities (MOSC) 12 commentsAnswered ✓

Greetings,

In a recent attempt to move from the traditional exp logical backup tool to data pump, large tables

are skipped over due to an ORA-01555 error. EXP works fine. Is increasing the rollback segment space going

to resolve this or is there more to it ? Oracle 11g

Thanks

Jeff
