DB2 High Performance Unload + remove unwanted data

Hello,

Linux RedHat AS4 running DB2 V8 FP15.

I have very large tables (100 Million+ rows), and I only need to keep
6 months of data online/available. The tables have a timestamp field.

I was hoping that DB2 High Performance Unload V3 allow me to 'extract
and delete' data from tablespaces very quickly, but unfortunately it
is only able to extract/export data (much faster than regular 'export'
statements).

Silly question: How do I efficiently remove unwanted data from very
large tables, without having to take my applications down ? DELETE
statements are fairly slow/unefficient with large tables.

PS: High Performance Unload is a great tool. You can extract tables
(full or parts of it) from a backup image. It is a must have for all
DBAs.

Thanks
