RE: view contents of datafile

Joe,

I am reading between the lines here, so bear with me. I think you will be disappointed with the results. Oracle (8.0.x at least) will assign extents in a round robin fashion across all online datafiles in a tablespace. All three files will have some extents in them. The only solution (well, there may be others) is to include a step to drop and recreate the tablespace after the export. And, assuming you export with compress=y, you can create empty tables in the rebuilt tablespace, and know before you import rows if the tablespace is large enough.

If my tablespace became so big that it had 3 datafiles and became so fragmented, then I export and import the whole databse, how can I tell if the REORG only used up one or two datafiles.

OR is there a utility to see contents of a datafile?

Joe
