Seema, The "ORA-1555 snapshot too old" occurs when export tries to construct a read consistent view of your data from rollback segments, which has been overwritten or reused for new transactions.
Other sessions are updating data while the export is running in consistent mode (using consistent = Y) To avoid the ORA-1555 - use consistent=N (default) - use larger rollback segments - increase the number of rollback segments - do exports during quieter periods ie. when not many users are manipulating data Regards $uhen Hi At time of export i am getting following error "EXP-00008: ORACLE error 1555 encountered ORA-01555: snapshot too old: rollback segment number 6 with name "R03" too small" Please suggest Thanks -Seema _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Seema Singh INET: [EMAIL PROTECTED] Fat City Network Services -- (858) 538-5051 FAX: (858) 538-5051 San Diego, California -- Public Internet access / Mailing Lists -------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
