Answer / subhash

1.Increase the 'Numbers Readers per Node' to '2' in source file.
2. Use the Bulk Load Option in Target Oracle Connector.
3. set option Re-Build Index option, so that it will drop indexes before loading and It will create the indexes once load is completed.
4. Increase the 'Record count'(set 10,000, should be multiple of Array size) in TGT.
5. Increase 'Array size'(set 5,000, default is 2,000) in TGT.
6. SRC---->COPY---->TGT,
use COPY stage, so, it work like buffer whenever there is diff in number records processing at source side and at target side.
