[Quoted] Same old problem .... slow imports

Is it wise to drop the PK index of the table (tables already exist before import) before importing. The documentation states that even if you specify INDEXES=N for the import, the unique indexes are still created.

Also, should I make 1 huge rollback segment for the import or set COMMIT and BUFFER parameters. What would be a reasonable BUFFER setting?

My imports are very slow!! Also, I noticed by looking at the alert.log file that I am doing a log switch very frequently. My redo logs are 10Megs. Is this unusually small? Should they be more on the magnitude of 100M?

By the way, I am doing direct mode exports. Platform: Solaris 2.6

Thanks for any insight!
