Folks,

We have some shedulars to load data in to tables in daily basis . Some times we get below error though we have enough space in tablespace and this cause loader failure .

ORA-1653: unable to extend table RBA.DT_TABLE by 12800 in tablespace RBA_DATA .

In the above case we have 400 MB freespace in RBA_DATA
tablespace , still we get the error .

Is there any way to monitor or predict this one or two days in advance so that we can take care about the situation .

thanks
