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.
