IDUG NA 2025

The intent of this presentation is to allow DBAs with either Db2 z/OS or Db2 LUW skills apply thier knowledge to the other Db2 platform. There is a lot of commonality between these versions of Db2, however there are some huge differences.  Deployment models, differences in functionality and how each is structured will be explained in detail.

Large language models (LLMs) have revolutionized AI by enabling a new category of applications called language apps. Enterprises have widely started using these apps for various purposes such as chatbots, document summarization, question–answering, and information retrieval. This has sparked renewed interest in AI in recent years. A crucial aspect of language apps is the generation of vector embeddings using language models. This process converts unstructured content, like PDFs, into AI–readable representations. These embeddings are used for vector similarity search, which offers more precise semantic search compared to traditional methods. However, vectors have high dimensionality, so they need cost–effective and secure storage, as well as efficient search methods. Db2 is introducing its first phase of vector support, which includes in–database vector storage, vector similarity search, and various vector operations. In this presentation, the Speaker will discuss Db2’s upcoming vector support features and how they can be utilized to develop modern LLM applications with Db2.

Db2 for z/OS provides several features to influence the query optimizer. Learn how to leverage these features to improve query performance, and to avoid access path changes that introduce the risk of regression after a BIND, REBIND or full PREPARE. Also, should an access path regression occur, learn what your options are to quickly restore performance.The session includes how Db2ZAI works with the Db2 optimizer to improve query performance while minimizing the risk of access path regression.

Bring your own device to this workshop, where you will have a chance to perform a hands–on lab to experience the latest deliverables towards Db2 user transformation. 

Db2 administrator personas can execute some of their daily tasks in a more intuitive way via Db2 Administration Foundation and its integration with Db2 Tuning Services, Query Workload Tuner and IDAA Administration services. Last but not least, administrators can also benefit from Db2 DevOps experience (DBaaS) to “shift–left” database operations to application developers under their rules and administrative directives.
Db2 application developer personas can develop / test and deploy application changes that also require database change in a speed that business demand. Using Db2 Developer Extension in IDE will simplify coding of SQL including native stored procedure code. Using Db2 DevOps Experience services (DBaaS), developers can, on demand, self–service database operations under the rules previously established by the Db2 administrators.
