Parallel option for DML

Question

Hi ,
I have 8 cpus on my server .
I want to insert data from tab1 into tab2 as follows :
insert into user1.tab1 select * from user1.tab2 ;
I wanted to utilize the parallel option in above query and i tried
INSERT /*+ PARALLEL(user1.tab1,5) */ INTO user1.tab1 SELECT /*+ PARALLEL(user1.tab2,4) */ * FROM user1.tab2;
query run successfully but i when i was monitoring from OS(IBM AIX 6.1) side using NMON utility , it was not consuming/utilizing more then 1 or 2 CPUs .
Can anyone plz tell me the correct syntax....

You've posted enough to know you need to provide your 4 digit Oracle version.

Please read the FAQ at the top of the thread list for how to post a tuning request and the info you need to provide. That info includes the DDL for the tables and indexes, the execution plan for the query you are running, the numbers of rows in the tables involved.
The execution plan will show if PARALLEL is being used.
