if you are going with traditional export (the one with exp) then you need to ensure you have a large enough buffer (think along the lines of largest row). Datapump is your best bet from 10g on. Though dblink replication won't work on long data, it's easy enough to export only tables containing longs to a dump and duplicate the rest with datapump over network link. hth Alan.- On Tue, Apr 23, 2013 at 1:13 AM, Raja Subramaniyan <raja.s28@xxxxxxxxx>wrote: > Hi, > I need to safely transfer databases / tables with LONG RAW coloumns from > one machine to another. > > What parameters have to be used to make exp work with the LONG RAW data > type and what are all the steps have to be taken? > > Thanks > Raja > > > -- > //www.freelists.org/webpage/oracle-l > > > -- //www.freelists.org/webpage/oracle-l
