shared pool content

I'm seeing significant pressure in shared pool after partitioning my DB. In statspak I can track rapid growth in a pool labled "partitioning d". Question... what is this? Is there any document that explains details of shared pool structure and contents? I'm interested in learning more about specific pool allocations such as "KQR M PO", "ges enqueues", etc. Snip from a 150 minute statspak report follow. Note the growth in "partitioning d".
