1) There are different types of variables in the Application Engine people code?
Local variable – these are available for the duration of the program in which they are declared.
Global / Component – These variables are available while the Application Engine program is running. They are saved at commits and checkpoints,
So they can be used for restarts. Component variables are same as Global incase of the AE.
2) What are the Different ways pass data between the steps?
1) State records – One row can be passed and can have many state records.
2) Component/Global People code variables
3) Temporary records – Multiple rows of data can be passed.
3) What is Prerequisite for the State record?
1) Should be either Derived work record Or SQL Table.
2) Name of the record must end in AET; this is how the system identifies the record as a state record.
3) PROCESS_INSTANCE must be a key.
4) Any data types except character or numeric must not be required fields.
Note: - No People code fires on an Application Engine state record.
No Validation of translate values or Prompt tables are done.
4) How to read the runctrl parameters in AE
1) SQL: - %Select (EMPLID) Select EMPLID from PS_AERUNCONTROL where PROCESS_INSTANCE = %PROCESS_INSTANCE and ORPID = %oprid
2) People code: - &SQL = “Select EMPLID from PS_AERUNCONTROL Where PROCESS_INSTACNE =” PS_TEST_AET.PROCESS_INSTANCE “and OPRID =” %oprid.
%PROCESS_INSTANCE or %Bind (PROCESS_INSTANCE) can be used.
%PROCESS_INSTANCE is more efficient and faster.
5) How do you execute Application Engine through Push Button?
1) CreateProcessRequest () , Schedule ()
2) CallAppEngine.
6) What is the syntax for CallAppEngine?
CallAppEngine (applid [, state record]);
7) What are the 3 trace parameters you can pass to your psae.exe?
- TRACE
- TOOLSTRACESQL
- TOOLSTRACEPC
8) Which Trace option is the best place to start for general performance information?
- TRACE 384 – mostly used trace value.
9) What is the difference between a Trace value and Trace parameters?A Trace parameter determines which type of trace is turned on.
A Trace parameter determines what type of data is recorded in your trace files (s).
10) What are the 3 common ways to pass a trace parameter and value to your program psae.exe?
Configuration manager, Process Definition, Command prompt.
11) What are the Different types of Application Engine?Standard: Standard entry-point program.
Upgrade Only: Used by PeopleSoft Upgrade utilities only.
Import Only: Used by PeopleSoft Import utilities only
Daemon Only: Use for daemon type programs.
Transform Only: Support for XSLT Transform programs.
12) How do you program AE program for the restarts?
Program Level State RecordOne of the state record needs to SQL Table, Since All Derived work record will be re-initializing on commit.
Program PropertiesOn the Advanced tab in the program properties dialog box, make sure that disable restart is not checked.
Configuration managerIn the configuration manager, sure that Disable restart is not selected on the process scheduler tab.
Section Level
Section type
The option for section type are prepare only and critical updates
If the section is preparing data i,e select data, Populating temporary tables, or updating temporary tables then the section should be prepare only.
If the section is updating the permanent application tables in the database, you should select critical update.
Step LevelAdd an order by clause
%Select Field Select Field1 from PS_SOME_RECORD Where FIELD1 > %Bind (FIELD1) Order by FIELD1.
Add a switch to the selected table
Delete processed rows.
The only restriction for batch runs occurs when you have restart enabled, and you are inside a Do Select that is of the Select/Fetch type (instead of "Re-select" or "Restartable"). with select/Fetch, all commits inside the loop are ignored, including the commit frequency if it's set.
13) What is Set Processing?
Set Processing uses SQL to process groups, or sets, of rows at one time rather than processing each row individually. With row by row processing you following a repetitive loop that selects a row, determines if it meets a given criteria, if so, apply rule x to row Update row, commit. With set processing, you only select those rows that meet the filtering criteria and then run the rule once again all the affected rows.
14) Advantages of Set Processing?
Improved Performance: - Our internal testing has revealed that, in an overwhelming majority of cases, set processing performs significantly better than it is -by-row counterpart for “reasonable” batch processing volumes.
Minimized SQL Overhead: - It tends to use fewer Application Engine SQL statements that each processed more data than the statements executed in row-by-row processing.
Easy Maintenance: - if need to make a fix or add an enhancement to SQL, it’s just a matter of modifying the SQL or inserting the new “Chunk”.
Leveraging the RDBMS: - With Set – based processing, you take advantage of the SQL processing engine on the database rather than placing the processing burden and overhead on the application executable.
15) Testing and debugging application engine?
Application Engine Trace file-You can track the step execution of your application execution.
Application Engine Interactive Debugger – First click on the trace tab and turn off the statement timings. Select Profile -> Edit Profile-> Process Scheduler Tab -> Application section Select Debug check box.
(You can dynamically modify the state record run application engine step by step
People Code Debugger for the Application Engine.)

Without the process instance: - AE__.AET
