Read File In Segments In Oracle Integration Cloud


Read File In Segments In Oracle Integration Cloud

Reading a file in segments in Oracle Integration Cloud is useful when dealing with large files that cannot be processed at once. This helps in conserving memory and improving performance. Here’s a high-level guide that you can follow to read a file in segments in Oracle Integration Cloud:

  1. Accessing the File: Depending on where the file is stored, you may need to use the appropriate adapter. For example, you could use the FTP adapter if the file is hosted on an FTP server, or the File adapter if it’s on a file system accessible by Oracle Integration Cloud.

  2. Reading in Segments: You’ll need to configure your integration to read the file in chunks or segments. This is typically done by specifying the segment size that you want to read.

  3. Processing Each Segment: You can then configure your integration to process each segment. This could involve transforming the data, mapping it to a different format, or whatever processing you need.

  4. Looping Through the File: You’ll likely need to use a loop to iterate through the file, reading and processing each segment in turn. This can be done using the While action in Oracle Integration Cloud.

  5. Managing Errors: Don’t forget to handle potential errors that might occur during the reading and processing of the file. You can use fault handling in Oracle Integration Cloud to define what should happen if an error occurs.

Here’s a simplified step-by-step guide that illustrates these concepts:

  1. Create an Integration: Start by creating a new integration in Oracle Integration Cloud.

  2. Configure the Adapter: Add the appropriate adapter (e.g., File, FTP) to read the file. During the configuration, you may find options related to reading in chunks or segments.

  3. Add a Loop: Use the While action to iterate through the file, reading a segment on each iteration.

  4. Read a Segment: Inside the loop, add an action to read the next segment of the file.

  5. Process the Segment: Add any actions needed to process the segment.

  6. Handle Errors: Optionally, add fault handling to manage any errors that might occur.

  7. Complete the Integration: Finish configuring the integration, and then activate it.

  8. Monitor and Test: Use Oracle Integration Cloud’s monitoring tools to test the integration and ensure it’s working as expected.
