Question 1 of 32 from exam 1Z0-1042-20: Oracle Cloud Platform Application Integration 2020 Specialist
Question
You need to create an OIC integration that will be processing many records individually that are contained within a large file.
You have been advised to use an implementation approach that includes using the Download File operation of an FTP adapter in conjunction with the Stage File action Read File in Segments operation to mitigate issues with memory consumption.
When using this approach, which is a valid consideration regarding the use of the Read File in Segments operation? (Choose the best answer.)

Sure!
The Read File in Segments operation in Oracle Integration Cloud (OIC) is a powerful feature that allows you to process large files in a memory-efficient way. When you use this operation in conjunction with the Download File operation of an FTP adapter, you can read a large file in segments and process each segment individually, without loading the entire file into memory at once. This can be particularly useful when dealing with large files that would otherwise consume too much memory to be processed efficiently.
Regarding the use of the Read File in Segments operation, the following is a valid consideration:
A. Segment sizes will default to 50 records but can be configured to any other segment size.
The Read File in Segments operation in OIC allows you to specify the number of records to be read per segment. By default, the segment size is set to 50 records, but you can configure it to any other segment size that suits your needs. This means that you can adjust the segment size based on the size of your file and the available memory on your system to optimize the processing of your file.
B. You will need to explicitly configure a Scope action for this operation if you want to add additional actions during the processing of each segment.
When you use the Read File in Segments operation, you need to wrap it in a Scope action if you want to add additional actions that will be executed for each segment. The Scope action is used to define the boundaries of the segment processing and to ensure that any variables used in the processing are properly scoped. This means that you need to explicitly configure a Scope action if you want to perform any additional processing during the segment processing.
C. The Read File in Segments operation allows for you to process the segments sequentially or in parallel.
The Read File in Segments operation allows you to specify whether you want to process the segments sequentially or in parallel. By default, the segments are processed sequentially, but you can configure the operation to process the segments in parallel if you want to optimize the processing time. This means that you can adjust the processing mode based on the available resources and the processing requirements of your file.
D. You must provide the actual filename because file references cannot be processed by the Read File in Segments operation.
When you use the Read File in Segments operation, you need to provide the actual filename of the file that you want to process. The operation cannot process file references, such as URLs or file IDs, directly. This means that you need to have access to the file system where the file is located and provide the actual filename to the operation.
In summary, when using the Read File in Segments operation in conjunction with the Download File operation of an FTP adapter to process a large file in Oracle Integration Cloud, a valid consideration is that the segment sizes can be configured to any size, you need to explicitly configure a Scope action to add additional actions, you can process the segments sequentially or in parallel, and you must provide the actual filename of the file.
