Question 18

Consider an App Engine process named `EMP_LOADER` designed to import employee data. The process has two sections: `Get_Data` and `Process_Records`. The `Get_Data` section retrieves employee records from an external source. The `Process_Records` section iterates through these retrieved records, updates employee information in the `PS_EMPLOYEES` table, and then calls a PeopleCode function `Validate_Employee_Data` for each record. This validation function, in rare cases, might throw an unhandled exception due to invalid data formats. An explicit `COMMIT` statement is placed at the very end of the `Process_Records` section. If an unhandled exception occurs within the `Validate_Employee_Data` function during the processing of the 50th employee record, what will be the state of the `PS_EMPLOYEES` table concerning the data processed before the exception?

Accepted Answer

All updates to the `PS_EMPLOYEES` table made by the `Process_Records` section, including those for the first 49 employee records, will be rolled back to the state they were in before the App Engine process began.

Question 19

A critical business requirement necessitates the integration of a PeopleSoft financial system with an aging, proprietary legacy system that generates daily transaction reports. This legacy system’s output is exclusively in a fixed-width, delimited flat-file format, and its specifications are unalterable due to its critical role and limited support.
