ORA-01562: failed to extend rollback segment number 11 I´m trying to execute this query into a SP

 DELETE FROM table SC
      WHERE SC.evaluationMonth= 'Some month';
 COMMIT;


But for this month there are something like 10 million records. So I get the error 


  ORA-01562: failed to extend rollback segment number 11. 


How can I improve the SP or make something to solve this problem?
Pdta: I had increase de unto to 20G
This isn't a coding issue - the rollback segment simply isn't big enough. Speak to your DBA about getting it extended.

Another issue could be other long running jobs hogging the available rollback space. Either way, the DBA should be your first port of call.
