How it works
------------

During an Oracle database checkpoint, dirty blocks from the buffer
cache are flushed to disk. Typically a checkpoint operation occurs at
a log switch - it's often the most write intensive operation in a busy
transaction processing database.

empower_checkpoint replays the writes captured from 4 real Oracle
checkpoints for tablespaces with different block sizes: 2K, 4K, 8K,
and 16K.

In each case the data loaded prior to the checkpoint is the same - a
250MB import of a TPC-C Customer table.

You don't even need an Oracle database to run the test.

In just a couple of minutes, empower_checkpoint will give you a
baseline for the performance of your storage for an Oracle I/O
intensive operation.

Disclaimer: if you run accidentally against a file with data you want
to keep, the file contents will be trashed.

Full usage details are in the readme file.
