Hi,
We are trying to migrate from Postgres to Oracle, although our DB is
gigantic
but we started on Mar 14th 2012 & its still running with an average of
400000 records per day
How can we check what is going wrong.
Any memory leak, CPU issue or anything.
Please help me fix it

Need more info.
How is Postgres setup, what version.
How are you migrating?
How is Oracle setup, what version.
Etc.

400,000? That's pathetic. Why didn't you just use Postgres's "copy to"
CSVS and then Oracle's SQL*Loader?
How big is "gigantic"?

If you are migrating *to* Oracle, then you should probably ask this question in an Oracle forum.
Or is it the reading of the old data that is that slow?
But anyway: without a lot more information about *how* you do the migration nobody will be able to help you
Which program(s) do you use to migrate the data?
What type of connection do you have between the two servers?
What exactly is slow (inserting into Oracle, selecting from Postgres?)
