Subject Re: full-import failed after 5 hours with Exception: ORA-01555: snapshot too old: rollback segment number with name "" too small ORA-22924: snapshot too old

Hi,

I'd go talk to the DBA.  How long does this query take if you run it
directly against Oracle?  How long if you run it locally vs. from a
remove server (like Solr is in relation to your Oracle server(s)).
What happens if you increase batchSize?
