Kamal,
This will be the pseudocode.
Procedure A()
select * from EMP bulk collect into records_array; --Of type RECORD_ARRAY
batch_count = (records_array.length) / batch_size;
--batch_size is say 5000 rows and batch_count is the number of batches  
for i in 1..(batch_count+1)
B( records_array);
C();
commit;
Procedure B(records_array in RECORD_ARRAY )
INSERT /*+PARALLEL(EMP_DUMMY, 2) */
INTO TABLE EMP_DUMMY
SELECT * from TABLE(CAST(records_array as RECORD_ARRAY) ;
Procedure C()
Other operations which include reads on the EMP_DUMMY table;
This is the top view of how it looks like. Actually the Select statement for the insert statement is very complex and I do a join on the records that are being passed in by casting it into a table. This query is taking about 40 minutes for 10,000 rows in the records_array. I need to parellelise this query because each row of the records_array yields a different row for the EMP_DUMMY table.
I hope that I made it clear for you.
Can you also tell me if procedure C in which I shall be doing a read on the EMP_DUMMY table, has any affect of the parallel insert
Thanks for your help.
