The Challenges & Our Solutions
Large Attachments
Uploading large Base64 files caused Oracle CLOB issues and blocked users.
Chunked Storage
Split files into 2,500-character chunks, store in a table, and reassemble later.
Performance Drop
Large uploads locked Oracle resources, reducing concurrency.
Optimized Inserts
Storing smaller chunks improved efficiency and allowed multiple users to upload simultaneously.
Oracle Downtime
Requests hung if Oracle was unavailable.
Retry Queue
Failed requests moved to RabbitMQ Retry Queue and retried automatically when Oracle returned.
System Responsiveness
Users had no feedback during Oracle outages.
Immediate Acknowledgment
Backend returned “Request queued” immediately while processing retries later.
Key Features
Efficient Large File Handling
ToMS handles large attachments such as images, documents and supporting files by breaking them up into manageable chunks of 2,500 characters. These chunks are processed and moved in a systematic manner to Oracle such that oversized requests do not impact the performance of the system. This improves upload reliability as well as allows processing of large files while other operations are performed.
Optimized System Performance
The chunk-based processing architecture minimizes resource consumption and also minimizes database locking during file transfers. Several users can upload, retrieve and process information at the same time with little impact on the responsiveness of the system. The optimized scheme enhances the total throughput and maintains the performance stable as the number of users and files increases.
Resilient Retry Mechanism
ToMS has a strong retry mechanism for handling temporary interruptions in Oracle service or connectivity issues. Requests are not dropped or permanently rejected (unless Oracle is available), and are queued automatically for retry. That means that the requests are queued, and retried automatically when the oracle service is back, providing reliable data.
Uninterrupted User Experience
Ensuring users are informed and responsive even when backend services are temporarily unavailable. The application does not wait for Oracle to recover, instead it acknowledges the request immediately and presents a status such as “Request Queued”. The rest of the work is done in the background . This is a seamless experience but it does guaranty that the requests are eventually completed .
