### Understanding fnd_request.submit_request and fnd_request.wait_for_request in Oracle E-Business Suite

By Zafar

In the realm of Oracle E-Business Suite (EBS), managing concurrent requests efficiently is crucial for maintaining smooth operations. Two key functions involved in this process are `fnd_request.submit_request` and `fnd_request.wait_for_request`. Let’s delve into these functions and understand their detailed usage.

#### fnd_request.submit_request:
This function is utilized to submit concurrent requests programmatically within Oracle EBS. It's particularly useful for automation purposes, allowing users to initiate various concurrent processes without manual intervention.

**Usage:**
```sql
l_request_id := fnd_request.submit_request(
    application => 'APPLICATION_NAME',
    program => 'PROGRAM_NAME',
    description => 'REQUEST_DESCRIPTION',
    start_time => NULL,
    sub_request => FALSE,
    argument1 => 'ARGUMENT_1_VALUE',
    argument2 => 'ARGUMENT_2_VALUE',
    ...
    argumentN => 'ARGUMENT_N_VALUE');
```

**Parameters:**
- `application`: The name of the application associated with the concurrent program.
- `program`: The name of the concurrent program to be executed.
- `description`: Description of the request.
- `start_time`: Scheduled start time of the request. If set to NULL, the request starts immediately.
- `sub_request`: Boolean parameter indicating whether it’s a sub-request or not.
- `argument1` to `argumentN`: Arguments required for the concurrent program. The number of arguments depends on the specific program being executed.

#### fnd_request.wait_for_request:
Once a request is submitted, it often needs to be monitored until completion. This function enables the program to wait until the specified request finishes execution, allowing for subsequent actions based on the request’s status.

**Usage:**
```sql
l_phase := fnd_request.wait_for_request(
    request_id => l_request_id,
    interval => 5,
    max_wait => 3600);
```

**Parameters:**
- `request_id`: The ID of the concurrent request being monitored.
- `interval`: The interval (in seconds) at which the function checks the request status.
- `max_wait`: The maximum duration (in seconds) to wait for the request to complete before timing out.

**Return Value:**
- `l_phase`: Phase of the request upon completion (`'C'` for Completed, `'E'` for Error, `'P'` for Pending, etc.).

### Detailed Usage Example:

```sql
DECLARE
   l_request_id NUMBER;
   l_phase VARCHAR2(1);
BEGIN
   l_request_id := fnd_request.submit_request(
       application => 'XX_CUSTOM_APP',
       program => 'XX_CUSTOM_PROGRAM',
       description => 'Custom Request',
       start_time => NULL,
       sub_request => FALSE,
       argument1 => 'ARGUMENT_1_VALUE',
       argument2 => 'ARGUMENT_2_VALUE');

   dbms_output.put_line('Request ID: ' || l_request_id);

   l_phase := fnd_request.wait_for_request(
       request_id => l_request_id,
       interval => 5,
       max_wait => 3600);

   dbms_output.put_line('Request Phase: ' || l_phase);
END;
```

In this example, we submit a custom concurrent request and wait for its completion. Upon completion, the phase of the request is retrieved and printed.

Understanding these functions empowers developers to automate processes effectively within Oracle E-Business Suite, streamlining operations and enhancing productivity.

Understanding the "Run Alone" Flag in Oracle E-Business Suite Concurrent Programs

In Oracle E-Business Suite (EBS), managing the performance and scheduling of concurrent programs is crucial to ensuring efficient processing and optimal resource usage. One of the features available to help manage this is the "Run Alone" flag. This setting allows administrators to control how a specific concurrent program is executed, especially when running alongside other programs. In this blog, we’ll explore what the "Run Alone" flag does, why it’s important, and best practices for its use. What is the "Run Alone" Flag? The "Run Alone" flag is a setting available in the Concurrent Program definition in Oracle EBS. When this flag is enabled, it restricts the concurrent program from running alongside other concurrent programs on the same concurrent manager. In essence, it tells Oracle EBS that this program must run exclusively, with no other concurrent requests processed until it completes. How to Set the "Run Alone" Flag You can enabl...
