Michael: Replying a few days late here. Does SAP have parameters internally that will help you control this? It does not really sound like exp/imp but it does sound like SQL*Loader. Can you determine what R3Load invokes? From there, we can help you a bit more. Thank You Stephen P.

This is an SAP system, and the export/import process uses a SAP-written utility called "R3load". That I know of, there are no settable parameters like the buffer parameter in an Oracle import. R3load writes to a flat file than is encoded and compressed using SAP's proprietary programming. It works very well at the compression angle. A 1.5TB database exported out to just under 300GB of flat files. The only tuning opportunities I have are on the database server. I can send out the whole initSID.ora file, but I thought that would be overkill for the first question. Thanks for the support!

If you are doing a conventional import then I would recommend you use a large buffer=3D value. If any of the exported options are unnecessary = for the import such as grants then set the associated parameter off for the = import: grants=3Dn. If the target tables exist and ignore=3Dy is in use and = some of these tables are large drop the indexes so they do not have to be = maintained during the table load. Either build them after or let the import = rebuild them.
