How does force_error function work ? If we set never abort in reformat , will force_error stop the graph or will it continue to process the next set of records ?

raja

• Feb 9th, 2015

Force_error function will not throw any error when we keep the reject threshold as never abort. but it will reject all unwanted records per requirement and will provide you the message.

1. If the requirement is to just move the files to Unix , you can do that using WINSCP tool
2. Depends on where you install GDE , in unix or windows ?
3. You can map the data after transforming (if required) to a target table.
4. Staging is not mandatory

Hello Raj,

Ab-Initio Certifications are only available in United States which can cost around $3-4k. Residents outside states dont have this privilege. Presuming that you are in India, I would recommend you to go-ahead with Teradata SQL and Oracle SQL Certifications.

If the stats are not collected on the table the index info is not available in the data dictionary, ,In such case the optimizer would pick up the full table scan instead of using the indexes. In order to always use the indexes we can give the hint to oracle to always use the index.

It depends on schema, since the star/snow flake schema has one fact table attached to multiple dimensions
so, I would go with 3rd normalized form.
