Open Source Database Questions

Because of the current economy we are being encouraged to consider open source databases.

One of the vendors has referenced a JTPCC benchmark which is an open source Java version of TPCC. Has anyone heard of JTPCC? Is it in any way truly comparable to TPCC? Keep in mind that I am skeptical of TPCC so this may be a loaded question.

Is anyone currently using open source databases in production? Our typical database is approximately 200G but the range is 50G to 3.5T. One of our typical databases has approximately 200 distinct users at any one time. Any thoughts on a sweet spot for open source databases?

This does all come down to money! I am pretty sure that we will have an open source database inhouse by year end. The major question is how best to use it.

Thanks,
