Hi, I'm currently working on building an interface that will update part of customer's data daily in CRM on demand. A file will have little over 9000 lines. I'm considering Data Loader utility for updating the records. I'm reading a document, Oracle Data Loader On Demand Guide and it looks like this utility is available in window only? Does this mean I can't run this utility in unix? I'm building in SOA environment so that it can orchestrate the transaction between legacy and CRM on demand and SOA system is installed in unix OS. What's my option for updating a large transactions?
