John, You might want to share the actual SQL command with us? Did you try the MINVALUE and MAXVALUE limits?

When I use the VERSIONS clause, I keep getting "ORA-30052: invalid lower limit snapshot expression". I have tried every reasonable set of timestamp values I can come up with, with no luck. There isn't a lot on this one Metalink or Google. Has anyone had issues with this or have some idea what may be behind it? I am running 10.1.0.3 on AIX 5.2. This is a 2 node RAC cluster. Any pointers would be greatly appreciated. Thanks, John P Weatherman Oracle DBA Advance America -- //www.freelists.org/webpage/oracle-l -- //www.freelists.org/webpage/oracle-l
