It's dependant on block size, or at least it was the last time I checked, which was a few years ago.

You can see the number of slots by doing a block dump the rollback segment.

Hello Folks,

I carried out a test, whereby I had just one rollback segment online with a
block size of 2K, and then running updates against the database thru different sessions without commiting any of them? As expected, it accepted the first 21 transactions, and on the 22nd transaction, threw an "Unable to
use system rollback segment for a non system .... " error.

When does Oracle report an "ORA-1554: Out of transaction slots" for a rollback segment?

Thanks
Raj
