I have modifies KM to be able to run a sql script using sqlplus. i made sure it runs OK in jython from command line D:\jython2.5.1>jython TEST_SQLPLUS_JYTHON.py. Please find the script below which fails when i execute in the studio using admin and does not populate the E:\ODI_file\TEST_SQL.log.
fyi.. I have also created SUPERVISOR id and gave admin access just to make sure I am covered from ODI.
