If you’ve been reading about concurrent programs in Oracle apps, you may be wondering how to get code for spawned programs. The concept of concurrent program executables is outlined in Oracle Application Object Library. Concurrency is a term that refers to running multiple concurrent programs with the same file name. It is used in programs that run concurrently and do not require extensions.
Concurrency
In Oracle applications, you can create a spawned program using the Request Set Stage Function. To do this, you can follow the steps below. Before starting any program, make sure it is ready to be used. You can also use Oracle’s Execute Command. This will start the execution of the spawned program. It should be called “exec”, but you can change it to whatever you want.
To use the default execution style of the spawned program, use Ctrl+S and select the appropriate option in the menu. The default value will be “File a Save.”
Using the spawned program, you can start the process from the operating system without the help of a concurrent manager. Alternatively, you can use the default user profile option to run the program. In either case, you should create an executable file. For this, navigate to the Application Developer responsibility. Once there, look for Executable and define it. This form defines the executable of the spawned program.
A spawned program has a name that will identify it from other programs running in the same database. It is often eight characters long. You can enter it in the application or description fields. Then, you need to choose an execution method. Java stored procedures are executables written in Java, so if your database uses an external database, you should use that one. This will ensure that the spawned program is able to interact with it and the operating system.
Compilation
The Compilation for Sprouted Program (CPS) is used to define the execution file of a spawned concurrent program in Oracle apps. The program’s execution file should match the file name of the compile of the EXMAIN.c program. In some operating systems, you can write your spawned concurrent program in a command language. In Oracle apps, spawned concurrent programs run in a separate process and consume more system resources.
The first statement of the concurrent program calls the fdpscp() function. This function retrieves the program’s parameters and prints a standard header in a log file. Then, the spawned concurrent program connects to the database and logs itself. If it is successful, the spawned concurrent program returns a TRUE. Otherwise, it returns a FALSE.
Usually, this code is compiled in two parts: the application and the server. The server process performs the actual work. It receives calls from the application and then processes them. In addition to processing the requests, it also processes data blocks from the disk. Combined, these two processes reduce the system overhead. This process is called a “combined process” in Oracle apps. This feature enables a single application to share the same library with several other processes.
A concurrent program should update the Who columns. Oracle Application Object Library loads the user profile options for a concurrent program. The concurrent program calls the function afpoget() to retrieve current values. The following table lists the user profile options that must be updated in concurrent programs. These options are updated during insert or update. These functions must be able to handle concurrent requests. You must also attach a Concurrent Program to a request group.
Execution
When you use the spawned program method in Oracle Apps, the executable that you want to execute must map to an AOL. Generally, you should pass a character string using the double quote, such as “This is an example of a ” (double quote). Similarly, you should include the executable that will be executed in the bin directory. Then, you can pass parameters to this concurrent program.
You can use an immediate executable type to execute a program. This executable type is a subroutine in the concurrent manager, which is used by Oracle. You can also use a multi-language function, which supports execution of a concurrent program in several languages. For example, a Java Stored Procedure should be named “executed.java”. However, a PL/SQL Stored Procedure should have a fully-defined name.
You should note that Oracle does not ship source code for the spawned program. However, the corresponding object files are found in the PRODUCT_TOP/lib directory. You can decompile these object files using a decompiler. An anonymous PL/SQL block, such as a report parameter, uses a spawned program. A spawned program may use a value set.
Concurrent spawned programs run in parallel, one on top of the other. Unlike traditional concurrent programs, the concurrent executable file can be manually run or scheduled to run. Concurrent processing allows you to use the entire hardware capacity of your application, and is typically used for long-running data-intensive tasks. But, the execution code for spawned programs in Oracle applications is often a PL/SQL Stored Procedure.
Printing
To print the code for a spawned program in Oracle apps, you must first determine the naming convention of the concurrent program. Generally, a concurrent report or program is named after its type. Then, you should go to the Responsibility View of the Oracle Application Object Library. Select the Concurrent Program and click OK. Afterward, choose the appropriate name for the concurrent report or program.
For concurrent programs, the execution method may be spawned, immediate, or stored procedure. Sprouted concurrent programs are run as independent processes and have their own processes. The latter requires additional steps before they can be submitted. Among these, they must be added to the program library and linked to the Oracle Application Object Library. For concurrent programs written in C or Pro*C, you must define the naming convention in the program.
Depending on the language used in the program, you can create a different executable file for the concurrent spawned program. A Java Stored Procedure, PL/SQL Stored Procedure, Oracle Reports, or SQL*Plus program can be created as separate executables. When creating these executables, you must ensure that the names of the C and Pro*C programs match.
You can also set different default settings for each row and column. Oracle applications will use the column and row lengths to determine the print style. You can also choose whether to save the report by pressing Ctrl+S or by using File a Save command. Then, your user will be able to change their default settings, such as spawning or terminating the process. In the meantime, you can also choose the printing style and submit the request.
Incompatibility
There are two ways to schedule your concurrent programs in Oracle applications: immediate and spawned. Immediate concurrent programs run as subroutines of a concurrent manager and spawned concurrent programs are stand-alone processes. Incompatibility of spawned programs occurs when SQL statements are not parsed between invocations. Therefore, instant and spawned concurrent programs use different system resources.
Concurrent processing is a great way to fully utilize the capacity of your hardware. Concurrent processing allows you to write multiple non-interactive, data-intensive programs that are scheduled to run in the background. This method is typically used to automate long-running data-intensive tasks. For example, if you need to run multiple transactions or run several data-intensive jobs, you can use Oracle applications’ concurrent processing functionality.
To resolve this problem, you must include the application you wish to use in the appropriate data group. To do this, read the Standard Request Submission chapter and refer to the Cross-application Reporting section. NULLs are allowed in form columns but should not be used when determining the data types. This way, you’ll be able to report on all data types. Using cross-application reporting is a great way to avoid incompatibility of spawned program in Oracle apps.
Concurrent programs can be C, Pro*C, or host-language programs. Concurrent programs must be placed in the application base directory. Similarly, they must be defined with Concurrent Program Executable form. In addition, they must specify the method of execution. In addition, the Oracle Application Object Library looks for these files based on the method the concurrent program will use. This is especially important for asynchronous applications.
