Trying to understand Fetch in a TKPROF output. We have an application on Oracle Apps Server 10.1 Database 10.2.0.4 On production, a specific query runs in about 3 seconds. On this new database server we created, it runs about 30 secs. Looks like the query does the same thing in the database, but we have a ton of SQL*Net message waits on the query below. What are Fetches? What are reasons why waits for SQL*Net messaging happens that relate to Fetches? See below...

Here it is:
