RE: Database writer

It's right there SID = 2, SERIAL# = 1. The name column is the THREAD running the background process. The program column is the PROCESS under NT which is ORACLE80.EXE. Oracle on NT runs ALL the oracle processes under one process with many threads that's why you need the join to v$bgprocess to get the thread name.
