Oracle LogMiner (Unsupported Operation)

oracle

I'm currently using Oracle 11g on RHEL5. I'm digging to see what are in the archived log files. After I query from v$logmnr_contents, I see many transactions of UNSUPPORTED operation.

What do these unsupported transactions mean?
I think that it's the cause that make my database generates lots of archived logs.
Moreover, I'm using global temporary table for generating reports. I discover that when I insert and delete from those temporary table, it also records in the archived log file.

How to do to reduce those recorded transactions?
