IBM DB2 11 for z/OS Buffer Pool Monitoring and Tuning


Book Description

IBM® DB2® buffer pools are still a key resource for ensuring good performance. This has become increasingly important as the difference between processor speed and disk response time for a random access I/O widens in each new generation of processor. An IBM System z® processor can be configured with large amounts of storage, which if used wisely, can help compensate by using storage to avoid synchronous I/O. Several changes in buffer pool management have been provided by DB2 10 and DB2 11. The purpose of this IBM RedpaperTM is to cover the following topics: Describe the functions of the DB2 11 buffer pools Introduce a number of matrixes for read and write performance of a buffer pool Provide information about how to set up and monitor the DB2 buffer pools The paper is intended to be read by DB2 system administrators, but it might be of interest to any IBM z/OS® performance specialist. It is assumed that the reader is familiar with DB2 and performance tuning. In this paper, we also assume that you are familiar with DB2 11 for z/OS performance. See DB2 11 for z/OS Technical Overview, SG24-8180; and DB2 11 for z/OS Performance Topics, SG24-8222, for more information about DB2 11 functions and their performance.




Integrating Db2 for z/OS Database Changes Into a CI/CD Pipeline


Book Description

The goal of this IBM® Redbooks® publication is to demonstrate the ability to perform single click automated deployments of multi-platform applications that include IBM Db2 for z/OS database schema changes by using the capabilities of IBM Db2 DevOps Experience for z/OS. Pushing the application and database code changes to a source control management system (SCM) triggers a single CI/CD pipeline execution for application and database changes. Therefore, it mitigates the dependency on the DBA to deploy those database changes in a separate process. At the same time, DBAs can safeguard the integrity of their organization's data by implementing site rules in Db2 DevOps Experience. DBAs define whether a schema change can be approved automatically after all site rules are satisfied or whether it must be approved manually. In this publication, we provide an overview of the CI/CD pipeline architecture in the context of a sample application. We also describe the steps that are relevant to the roles of the DevOps engineer who implements the enterprise CI/CD pipeline, the DBA who is responsible for database code changes in Db2 for z/OS and for defining site rules that ensure quality in production, and the application developer who changes the application code and communicates requirements for changes in the database schema.




Installing and Configuring IBM Db2 AI for IBM Z/OS V1.4.0


Book Description

Artificial intelligence (AI) enables computers and machines to mimic the perception, learning, problem-solving, and decision-making capabilities of the human mind. AI development is made possible by the availability of large amounts of data and the corresponding development and wide availability of computer systems that can process all that data faster and more accurately than humans can. What happens if you infuse AI with a world-class database management system, such as IBM Db2®? IBM® has done just that with Db2 AI for z/OS (Db2ZAI). Db2ZAI is built to infuse AI and data science to assist businesses in the use of AI to develop applications more easily. With Db2ZAI, the following benefits are realized: Data science functionality Better built applications Improved database performance (and DBA's time and efforts are saved) through simplification and automation of error reporting and routine tasks Machine learning (ML) optimizer to improve query access paths and reduce the need for manual tuning and query optimization Integrated data access that makes data available from various vendors including private cloud providers. This IBM Redpaper® publication helps to simplify your installation by tailoring and configuration of Db2 AI for z/OS®. It was written for system programmers, system administrators, and database administrators.
