We are on sap erp r/3 4.7 110 (oracle 9, solaris 9). we are doing a migration based r3load and we export the source sytem. at first the exporting table speed is neary 800MB/H. but it comes to 100MB/H when it exports a big tabl name BSIS, which size is nealy 30GB. i caculate the speed via monitoring exported file size . i've ready run db update statistic job before we export db. it seems no work.
how can i accelerate the exporting big table speed ? thx in advance.
