SQL Issue in Oracle

Richard_Ma_(mtrcadmin_-_(deleted))

I found that in my Livelink Oracle database, the following SQL is triggered by Livelink and this SQL generated a "sequential write" in Oracle which was slowing down the Oracle performance. Do anyone knows why this SQL will be triggered and how to avoid it. Thanks.select file#,block#,length from uet$ where ts#=:1 and segfile#=:2 and segblock#=:3 and ext#=:4
