    OFsX

    Oracle File system Extension

    Problem: How can Oracle PL/SQL applications read, write, move or copy arbitrarily large files to or from arbitrary file system locations? Solution: This utility (OFsX) uses PL/SQL, Oracle AQ & Spring Integration to handle reading, writing, copying, moving & deleting of files from Oracle PL/SQL in a general way. Summary: PL/SQL is an excellent language for developing data-intensive, enterprise applications. However, it can be difficult for PL/SQL applications to interact with a file system (Fs). OFsX makes two-way PL/SQL-to-Fs interaction easy.

    OMapper

    OMapper

    Automate your bean mappings seamlessly

    OMapper is a simple library to ease the process of mapping objects or beans from one design layer to another design layer, using annotations. One can specify mappings both in source class (Sink Annotation) and target class(Source Annotation). Supports mapping composed user class objects and array fields. It is NOT an ORM Framework like Hibernate, but it facilitates object to object mapping between different design layers. So, say if hibernate or axis generates DTO's and you want to map them to your own beans , so at that point this framework can be used. Please refer to the wiki for usage guidelines. Key Benefits : => Smaller code foot-print => Faster development time => One time mapping creation => Easy to debug => Reduces the bugs due to missed mappings for large DTOs

    Odigos

    Odigos

    Distributed tracing without code changes

    Odigos supports any application written in Java, Python, .NET, Node.js and Go. Historically, compiled languages like Go have been difficult to instrument without code changes. Odigos solves this problem by uniquely leveraging eBPF. Odigos currently supports all the popular managed and open source destinations. By producing data in the OpenTelemetry format, Odigos can be used with any observability tool that supports OTLP. Odigos automatically scales OpenTelemetry collectors based on observability data volume. Manage and configure collectors via a convenient web UI. Installing Odigos takes less than 5 minutes, and requires no code changes.
