My 9.3 IDS instance runs on an IBM RS6000 server( 4-way SP winterhawk node 450 MHz running AIX). Everytime an onbar logical log backup kicks off, I have noticed that it takes 25% of CPU resources(1 CPU). Can somebody explain why the logical log backup process is so resource intensive(all it should be doing is moving records from the logical log on disk to the tape sub-system)?
