The IQ main store and IQ temporary store space management has undergone some improvements in Sybase IQ 15.0.
The user with DBA authority can now limit the amount of space used per connection. In addition, when IQ runs out of space in IQ main store or the IQ temporary store, it no longer suspends the transaction that ran out of space until new space is added. In IQ 15.0, the transaction that runs out of space in the IQ main store or the IQ temporary store will fail and gets rolled back.
