First statement before you start processing?? SET TRANSACTION USE ROLLBACK SEGMENT BIG_RBS1; OR dbms_transaction.use_rollback_segment(‘BIG_RBS1’);
column last_number format 9999999999999999 select * from user_sequences where sequence_name in (‘UOC_ORDER_SEQ_ID’); select 2400000000 – CurrVAl – 20 LAST_NUMBER from dual; alter sequence UOC_ORDER_SEQ_ID increment by NOCACHE; Increment Once. select UOC_ORDER_SEQ_ID.nextval from dual; Confirm Value comes to 2300000000. After that alter sequence UOC_ORDER_SEQ_ID increment by 1 NOCACHE; alter sequence UOC_ORDER_SEQ_ID maxvalue 2499999999 NOCACHE;
