Inconsistent sizes of archive logs in 11.2.0.2

I'm wodnering if anyone has seen this issue with archivelogs before. We have a test/qa system and a sandbox system, both recent copies of our production database. Both are Oracle 11.2.0.2 with the same patch level and bug fixes applied. Both have redologs of size 100mb. On one system, we get archivelogs that are about 80-90mb in size. This is what I would normally expect. On the other system, we get archivelogs that are only about 20-30mb in size, and we get about 3-4 times as many. Does anyone know what may cuase such a drastic difference in archiving?

Thanks.

Hello Dale,

maybe some script or monitoring software executes some "manual" log switches?

Maybe you have set the parmaeter ARCHIVE_LAG_TARGET?
