Interview Q&A -3: Concurrent Program

Bishnu Prasad Choudhury / / 1

Concurrent Programs
  1. How do you register a report? Explain passing of parameters between a concurrent program Definition and report?
        After developing the report (.rdf), FTP it to the UNIX server.
        Define executable.
        Define concurrent program and attach the executable.
        Attach the concurrent program to a request group.

2       2.    What is the approach to create a new form to be used in Oracle Apps?
The TEMPLATE form is the required starting point of all development of new forms. Start Developing each new form by copying the TEMPLATE.fmb file, located in $AU_TOP/forms/US(or your language and platform equivalent), to local directory and rename it as appropriate.

  1. Explain Value Set? Difference between a Table Validated and Independent Value Set?
A set of values against which Oracle Application Object Library validates values your end users enter when running your program. You define your value set by specifying validation rules, format constraints and other properties. For example, you could define a value set to contain values that are character strings, validated from a table in your application. You can specify that oracle application Object Library use the same value set to validate different report parameters. You can also use value sets that you use in your flex fields to validate your report parameters.

  1. How do you create a table validated value set dependent on another value set?
Use :$FLEX$.<Value set name> in the where condition.

  1. What is difference between a concurrent request and a concurrent request set?
Concurrent request set is the combination of multiple requests which will run in a sequence.

  1. What are the two mandatory parameters required for running a PL/SQL Procedure based concurrent program? 
         Errbuf, Retcode

7.    How can you ensure that only one instance of a concurrent program runs?
         Check the ‘Run Alone’ check box in Concurrent program registration window.

8.    Within a PL/SQL procedure which API is to be used to extract a profile value?
         FND_PROFILE.GET

9.    How do you set the operating unit context in a report?
          Begin
          Dbms_application_info.set_client_info(<Organization_Id>);
          End;

10. Can you submit a concurrent request from the operating system directly?
Write a Shellscript.
Login to database
Run the function FND_REQUEST.Submit()

11. Explain how to generate a trace file for a pl/sql concurrent program for tuning?
          Check the ’Enable Trace’ check box in concurrent program registration window.

12. How do you “write” to the concurrent request Log and Output file?
          FND_FILE.PUT(FND_FILE.LOG or FND_FILE.OUTPUT, <Text>);
