Check the character set in your data base side.

use:
select * from nls_database_parameters where parameter='NLS_CHARACTERSET'
also check your DS Director log. Especially the second log which has the environmental settings: Check the NLS.

you can use the Oracle load option parameter in your job but make sure your data is clean. If you have already staged the data in a dataset ot sequential file then use bulk loading option, because i have many times faced issues with index (being unusable -due to duplicate data).

Do a row count before going for a join stage. If the row count is very less use SQL query to join the tables, ot use a look up instead, go for join only if its necessary(very huge data/less space)

Allow stage write cache -- this is not checked
create file --- not checked

When reading:

Pre-Load file to memory:
Enabled --> is chosen. so do you want me to disable this and try.

"Is this hashed file the source for your surrogate key? If so this could be part of your issue. "

Yes. you are right. this file stores only the table name ans the column name and the surrogate key.
