To change retention of securefiles use (retention min ) clause.

eg:

alter table 
 modify lob () (retention min );



alter table test.cust_int modify lob (c_lob) (retention none) ;

 alter table test.cust_int modify lob (c_lob) (retention );

Table altered.

alter table test.cust_int modify lob (c_lob) (retention default);




 

To check

 

For Non-partitioned LOB

select TABLE_NAME,COLUMN_NAME,SECUREFILE,RETENTION_TYPE,RETENTION_VALUE from dba_lobs where table_name='';

 

For partitioned LOB  

select TABLE_OWNER,COLUMN_NAME,LOB_NAME,DEF_PCTVERSION,DEF_RETENTION,DEF_MINRET from dba_part_lobs where table_name='';


select TABLE_NAME,COLUMN_NAME,PCTVERSION,RETENTION,SECUREFILE,RETENTION_TYPE,RETENTION_VALUE from dba_lobs where table_name='CUST_INT';
