Oracle Database Multilingual Engine

The Multilingual Engine (MLE) research project investigates how to leverage programming language runtimes in database systems (DBMS). Our hypothesis is that application development and data science can benefit from running code as close to the data as possible. For example, Python workloads for training machine learning models can run directly in the DBMS, using the DBMS as a compute cluster with efficient access to data. Similarly, the best place to run data-centric applications can be the database system itself, completely eliminating performance concerns due to network round trips and reducing infrastructure costs. The focus of our work is to enable Oracle Database to execute such workloads written in modern and popular languages and frameworks. The foundation for the project is GraalVM, Oracle Labs’ high-performance, polyglot programming language runtime. A first outcome of our vision is the JavaScript support in Oracle Database 23c.

Additionally, we leverage Just-In-Time (JIT) compilation to improve the performance of database query processing. We explore making queries on relational tables and document collections faster using code generation and JIT compilation, all based on GraalVM and the Truffle framework.

Internships in the MLE project offer the opportunity to work with state-of-the-art technology at the crossroads of database systems and programming language runtimes. The MLE project conducts research with a strong focus on practical applicability.

Software Supply Chain Security in the Cloud

Adoption of third-party open-source software (OSS) has increased significantly over the last few years. And for a good reason: OSS helps developers lower costs and reduce time to market by reusing existing components as building blocks for their applications. At the same time, vulnerabilities in OSS pose a significant risk to application security. Developers need to keep track of their (transitive) dependencies, known vulnerabilities (CVEs), and upgrade dependencies whenever a new CVE is found. Application Dependency Management (ADM) is an OCI-native service that helps managing dependencies in the customers software supply chain. ADM is exploring and researching the software composition analysis space to help users manage the risk associated to using 3rd parties.


Potential Topics

The goal of this project is to extend the Application Dependency Management cloud service with new capabilities in the areas of automated tuning and upgrades, patching security vulnerabilities in application dependencies and automated testing. We offer various topics depending on the skills and the interests of the candidate:

  • Improve Vulnerability Curation Process: Application Dependency Management provides a knowledge base of artifacts and their known vulnerabilities (CVEs). New and updated CVEs need to be processed to identify the list of vulnerable artifact versions. This curation process currently involves different tools and scripts, but there is no single solution to optimize the time to curate the CVE itself. The objective of this internship is to evaluate the potential of Data Science and Artificial Intelligence techniques, including machine learning, to automate the manual labor involved in the CVE curation process and enhance its overall efficiency. Additionally, the internship may also encompass the development of a user-friendly application to support the entire CVE curation process, further optimizing it through increased automation.
  • Build Profiles of third-party libraries: Modern applications heavily depend on open-source software components (dependencies). Developers are often not aware of what capabilities these dependencies need. For example, if the dependency makes network requests, load code at runtime, start new threads or write to the file system. Giving developers insight into the capabilities that their dependencies require could help them make more informed decisions about which dependencies to include. The goal of this internship is to develop a system to automatically detect what capabilities does an open-source dependency need based on the available test suite. Third-party libraries can suffer from vulnerabilities that are associated with a score according to the Common Vulnerability Scoring System (CVSS). This score will depend on the severity of the vulnerability, however, such score can only be determined if a vulnerability for the third-party has been found. Another objective of the internship could be to evaluate a risk score (additionally to CVSS) for third-party dependency libraries. Different paths can be explored towards this idea, such as a risk score taking into account the maturity of the project and its code repository (project still maintained, license, security policy); the usage of third parties (frequency and ways of usage); how big, how complex the library is, how much is it used in other projects.
  • Evaluate impact of changing a 3rd party library: At the moment, ADM remediation runs the CI/CD pipeline of the customer’s service to confirm that updating a vulnerable dependency did not break the customer’s application. The idea behind this internship topic is to improve this verification, to also include the historical data about the application and evaluate impact of changing a 3rd party by simulating an execution based on a recorded trace of an older version and see if exercised code path is the same. High level idea is to replay the history of the service , but to replace the version of the application that was used at the time with the updated version. Once this test is run, the verify step would have a better idea of how likely the dependency upgrade is to break the application, and this can be communicated to the user through something like a “disruption score”.
  • Query engine on top of Java heap dumps and compilation trace to aggregate and find 3rd party issues: Nowadays open source libraries are used in every project helping developers to not have to re-invent the wheel. These open source libraries are usually trusted by developers and do not go through code review. This opens up the possibility of pulling libraries which contain issues such as memory leaks which are very hard to debug and find. The idea of this internship topic is to find a way to collect Java heap dumps – just enough to build the data lake – making sure that this collection does not impact the performance of the respective service. The detection algorithm should work on top of this data lake and its result should be used to figure out which open source libraries contain memory leaks. The data about open source libraries should be made available to developers in an easy to query manner.

Graal Cloud Service

Oracle Labs is building the next generation serverless platform that provides a fully managed on-demand compute platform for Java users. It brings following benefits to the end user:

  • Developer Productivity - Developers can use GCN provided APIs and tools to develop applications. GCN is an opinionated API for developing multi-cloud applications.
  • Cost Efficiency - Scale to zero is supported without sacrificing cold start latency, so idle applications are not charged to customers (except for private mode).
  • Simplicity - Developers don’t have to learn about containers, networking, SSL, etc. to run production grade application.

Graal Cloud Service (GCS) uses GraalVM native image, a technology to ahead-of-time compile Java code to a standalone executable. Additionally, the service leverages GraalOS, a new virtualization technology built on top of modern hardware features, such as control flow integrity and in-process memory protection features, compilation techniques to isolate untrusted code execution.


Potential Topics

The goal of this project is to extend GCS with new capabilities. We offer various topics depending on the skills and the interests of the candidate:

  • Detect and mitigate metastable failures for applications running on GCS: Metastable failures1 are a class of failures in distributed systems in which a “sustaining effect” prevents the system’s quick recovery after a temporary “trigger”. These failures can be sustained by so-called “Workload Amplification” or “Capacity Degradation Amplification” effects. Examples of sustaining effects include retries, garbage collection, look-aside cache. The GCS platform, acting as a cloud orchestrator managing all/parts of the distributed components of the application and with its virtualization layer, offers the opportunity to detect those issues with a better overview of the states of the components. It can also offer the possibility to correct those issues with or without the aid of the application framework.
  • Secure and optimized cross-isolate communication for GraalOS: The BlackBox paper describes a technique to improve container isolation. Traditionally, container isolation is guaranteed by the operating system. However, operating systems are big code bases that occasionally have vulnerability. Instead, BlackBox runs a container security monitor (CSM) between the container and operating system. The CSM creates protected physical address spaces (PPASes) for each container such that there is no direct information flow from container to operating system or other container PPASes. The authors make clever use of the hardware’s virtualization support to run the CSM at the level of a hypervisor, i.e. a higher privilege than the kernel and user space. However, the CSM is not a hypervisor itself: it still delegates memory management and task scheduling to the OS. Containers are prohibited from accessing each other’s memory and communication between the container and OS is encrypted. In the context of GraalOS, one internship topic would be to investigate the current techniques by which Native Image Isolates are isolated, and whether the techniques from BlackBox can be used to improve this isolation.
  • Platform to analyze application usage to optimize Graal VM Native Image creation: GraalVM Native Image compiles Java code ahead-of-time to a standalone executable. It has the benefit of significantly improving startup time as well as memory footprint. However, peak performance of native image is lower than peak performance running on a traditional JVM that does just-in-time compilation. GraalVM can apply profile-guided optimizations (PGO) for additional performance gain and higher throughput of native images. With PGO, one collects the profiling data in advance and then feeds it to the native image builder, which will use this information to optimize the performance of the resulting binary. The goal of this internship is to extend the Graal Cloud Service to automatically generate and apply profiling data for applications that are running on the platform, effectively simplifying the generation of optimized native images.
  • Tailored security policy generation: parameters refinement: he least privilege principle states that an application should run with the least amount of privileges possible. Today, this principle can be enforced by creating a tailored security policy for mechanisms such as Seccomp, AppArmor & SELinux. However, manually creating such a security policy (i.e., defining the smallest set of privileges that is necessary for the application) is a tedious, error-prone task and one that needs to be revisited every time the application changes. Previous works have shown that it is instead possible to discover, with good accuracy, the smallest set of necessary privileges using static analysis of the source code and thus automatically generate the security policy. Our proposal is to extend this previous approach with symbolic execution to further restrict the privileges of an application. For example detecting that an application is only meant to connect to one specific IP address and thus generates a security policy that forbids connection to other IP addresses, or detecting the set of actual parameters used for a system call and forbids calls to this system call with other parameters.
  • Automatically derive OCI IAM policies: In this internship, we will explore automatically generating OCI IAM policies for a given native image application. First, we will use static analysis to understand the application’s usage of the OCI SDK. Second, analyzing OpenAPI specification (and source code) of OCI cloud services, we will build a database of the permissions for each REST operation. Putting the two information together will enable generating policies, optimizing for giving the least privilege possible to the application
