Database Performance: large Table getting redistributed causing performance problems - forum topic by nag@rjuna

Hi ,
Good Morning,
I have this performance problem where in I have to join a big table (> 1million records ) on column(which is a part of PI) to get few columns(4) to the semantic layer. I have implemented the code , but the explain plan says the table getting redistributed for every load running. Redistributing 1 Million records for every load(batchly - 1 hr) is causing bottle necks for other queries).
 
Technical details:(Table names and columns are masked for security reasons)
 Table to be joined with : Financial_Statement -- no of columns 98
                                                     --no of rows > 1million
                                                     --PI(col1,col2,col3,col4) all are varchar(100)
                                                     --NUSI(col60,col70) integer and char datatypes
                                                     --Vosi(col45) date datatype
 
here col2 is used in joining condition.
 
 
Would appreciate any help!!!
 
Thanks in advance.
