Table partition strategy

edited Oct 10, 2013 5:58AM in Database Tuning (MOSC) 5 commentsAnswered
Hi All,

I am using oracle 11.2.0.6 database on Linux 5.9 plateform. One of my database partition table size is around 400GB. Table have 150 columns and 334529000 num_rows.  I have to redefine the partition strategy as data is not equally distributed and facing performance issues.

Existing  : PARTITION BY RANGE ("Col_1")    SUBPARTITION BY LIST ("Col_2")
Proposed : PARTITION BY LIST ("Col_1")  SUBPARTITION BY LIST ("Col_3")

My Question : Can you please help in followings ...

    1- what would be best way to load the data from existing partition table to new partition table?

    2- what is best approach for indexing?

Let me know for more info

Howdy, Stranger!
