No its not a batch insert; each insert is done with auto-commit=true from
the java application. So, after each insert a commit is done at the Db
level, which is the root cause of such a delay, I guess.
But if this auto-commit is the issue than why first 10K records are inserted
quickly.
I cannot disable constraints even for a sinlge second as there will be heavy
reads going on even when inserts are taking place.
Any clues?

Marul,
I think this question needs to be answered, otherwise impossible to make
suggestions...

Marul, what i fail to understand is:
Are you running a batch job of inserting 350,000 inserts?
If that is the case then you should go for dropping and recreating the
indexes. Can you partition the table and use local partitioned indexes?
Can't you try the option of inserting in parallel?
Did you try disabling the constraints and then ENABLE NOVALIDATE them(that
will only work if you r sure of the data)?

Thanks Chris,
So than any clues how to resolve this issue, as earliest, becuase this is

Good question, Jared! Perhaps 'overflow' is technically not the
term to use to decribe this scenario but it seemed to fit the bill
sufficiently to mail off a quick one-liner solution without going into great
depth. Some of us have work to do, you know;)
To redeem myself I probably should have mentioned that this table
sufficiently to mail off a quick one-liner solution without going into great

To redeem myself I probably should have mentioned that this table
pretty volatile. Consequently the index(es) are likely to end up fairly
disorganized, especially if the 350k records are being inserted in
ascending order. Once you start adding levels to the index things
disorganized, especially if the 350k records are being inserted in
ascending order. Once you start adding levels to the index things
