Error when deleting a customer table

Question

Hi guys, im deleting a Z table with a loop, and the following error is displayed after 10 minutes.
the log reads as follow.
1. ORACLE storage space request failed.                                
    (ORACLE error 1547)                                                
To execute this operation, the ORACLE instance needs more              
storage space for a segment. This storage is                           
managed by ORACLE in logical units known as extents.                   
The size of an extent depends on the segment definition and            
the current storage situation.                                                                               
One segment (possibly more) is stored in one tablespace.               
The storage space available for a tablespace must be explicitly        
preallocated by the database adminstrator. If, in course of time, the  
volume of data in this tablespace increases considerably, the storage  
space may be filled up (in real terms or through fragmentation).       
2. Maximum number of extents reached for rollback segment.             
    (ORACLE error 1556)                                                
To execute this operation, the ORACLE instance needs more              
storage space for a segment. This storage is                           
managed by ORACLE in logical units known as extents.                   
The size of an extent depends on the segment definition and            
the current storage situation.                                                                               
For each segment, the ORACLE instance can manage only a certain number 
of extents. The maximum number for this                                
segment has been reached.                 
HERE THE CODE:
DO 48 TIMES. " HASTA 4 años.
DELETE FROM (p_ztable)
WHERE perio = periodo.
IF mes = '01' OR mes = '1'.
mes = 12.
anio = anio - 1.
ELSE.
mes = mes - 1.
ENDIF.
CONCATENATE ANIO '0' MES INTO PERIODO.
ENDDO.
any ideas?

Answer 1

Looks like the temporary memory pages are overflowed.
System hold the data in the temporary memory to enable ROLLBACK work.
So, we need to either do the COMMIT WORK or ROLLBACK WORK after cretain number of data.
Or, Reduce the number of loops and process smaller number of data at a time (before next COMMIT or ROLLBACK work).
