In literal terms, IBM Db2 is a family of data management products, including the Db2 relational database, and the products feature AI-powered capabilities to help you modernize the management of both structured and unstructured data across on-premises and multi-cloud environments. By helping to make your data simple and accessible, the Db2 family positions your business to pursue the value of AI.
As, most of the Db2 family is available on the IBM Cloud Pak for Data platform, either as an add-on or an included data source service, making virtually all of your data available across hybrid or multi-cloud environments to fuel your AI applications. Easily converge your transactional data stores and rapidly derive insights through universal, intelligent querying of data across disparate sources. Cut costs with the multi model capability that eliminates the need for data replication and migration. On the other hand, it enhances agility by running Db2 on various cloud vendor.
As a result, one of the crucial areas for tuning DB2 subsystem performance is that of its memory usage. DB2 for z/OS uses memory mainly for buffer pools, the EDM pool, RID pool and sort pools in order to cache the data and structures in memory. Thus, the better memory is allocated to these structures, and better the DB2 will perform.(Read more to know the guidelines)
