I tried this at your suggestion (though it didn't look like it was analyzing as there were not status on the tables). This didn't help. I even tried turning off archiving and no joy.

Sounds strange and I can't give you any good reason but I do have one idea. Have you tried:
analyze=n

If you take RAC out of Oracle you get OLE! What can this mean?

Oracle 8.1.7 on Solaris 8

I am testing and upgrade from 7.3.4 to 8.1.7. Because the test server is solaris 8, and I can't find the patches for 7 anymore, I am trying to upgrade via an export and import. Besides, the DB is small - less than 2G. The export was done with compress=n. There are 200+ tables to be imported. It is taking 3+ minutes per table for the import, even on tables that have 0 rows. (Though it does take longer than that for the few tables with over 50K rows).

I have tried:

1. Simple import.
2. Import with indexes=n
3. Import with table and constraints (but not indexes) pre-created and indexes=n ignore=y
4. All of the above with the buffer set to 8M (This actually slows the import down, taking 5+ minutes per table).
5. Increasing the sort_area_size for the DB to twice as large as it was and trying the above.

In looking at how long it takes, the table imports in a second or less, but it takes 3 minutes + to start the import of the next table. I'm not sure what it is doing for 3 minutes after the table imports.

Does anyone have any ideas how I can speed this up? 10 hours to import a 2G. DB is extreme and unacceptable.

TIA. Terry
